      <h1 class="heading">DbProviderFactories and You</h1>
      <p>One of the great new features of ADO.NET 2.0 is the use of reflection as a 
        means of instantiating database providers programmatically. The information 
        .NET uses to enumerate the available data providers in the system is relatively 
        simple. It merely looks in the machine.config and in your own app.config file for some XML data to tell it what providers are 
        installed and what assemblies those providers are in.
      </p>
      <h4>
        Scenario 1:&nbsp; Version Independent (does not use the Global Assembly Cache)</h4>
      <p>
        This method allows you to drop any new version of the System.Data.SQLite.DLL into
        your application's folder and use it without any code modifications or recompiling.&nbsp;
        Add the following code to your app.config file:</p>
      <div class="syntax">
        <PRE>&lt;configuration&gt;
  &lt;system.data&gt;
    &lt;DbProviderFactories&gt;
      &lt;remove invariant="System.Data.SQLite"/&gt;
      &lt;add name="SQLite Data Provider" invariant="System.Data.SQLite"
           description=".Net Framework Data Provider for SQLite"<br />           type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" /&gt;
    &lt;/DbProviderFactories&gt;
  &lt;/system.data&gt;
&lt;/configuration&gt;
</PRE>
      </div>
      <h4>
        Scenario 2:&nbsp; Version Dependent, using either the DLL located in the same folder
        as the application or the Global Assembly Cache</h4>
      <p>
        This method expands on the above XML to provide the version number and key token
        of the SQLite DLL so it can be found either in the same folder as the application
        or looked up in the GAC.&nbsp; The downside to this method is that DbProviderFactories
        will use this version information to only load the version specified.&nbsp; This
        means if you update the DLL, you must also update this XML.</p>
      <div class="syntax">
        <PRE>
&lt;configuration&gt;
  &lt;system.data&gt;
    &lt;DbProviderFactories&gt;
      &lt;remove invariant="System.Data.SQLite"/&gt;
      &lt;add name="SQLite Data Provider" invariant="System.Data.SQLite" 
           description=".Net Framework Data Provider for SQLite"
           type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite,
                 Version=1.0.77.0, Culture=neutral,
                 PublicKeyToken=db937bc2d44ff139"/&gt;
    &lt;/DbProviderFactories&gt;
  &lt;/system.data&gt;
&lt;/configuration&gt;
</pre>
      </div>
      <p>
        The following C# code demonstrates 
        instantiating SQLite through DbProviderFactories:</p>
      <div class="syntax"><pre>      DbProviderFactory fact = DbProviderFactories.GetFactory("System.Data.SQLite");
      using (DbConnection cnn = fact.CreateConnection())
      {
        cnn.ConnectionString = "Data Source=test.db3";
        cnn.Open();
      }</pre>

      <h1 class="heading">Installing SQLite Visual Studio Design-Time Support</h1>
      <p>Supporting the Visual Studio query designer and allowing you to manipulate 
        SQLite databases from within Visual Studio is a great time-saver.&nbsp; Though 
        the support is not yet fully-implemented, there's certainly enough there to 
        keep you busy.&nbsp; You can create databases, design and execute queries, 
        create typed datasets and lots more all from Visual Studio.</p>
      <h3> Installation Instructions</h3>
      <p>
        In Windows Explorer, navigate to <STRONG>SQLite.Net\bin\Designer</STRONG>
        and execute the <STRONG>INSTALL.EXE</STRONG> program.&nbsp; It will automatically
        detect what eligible Visual Studio products are installed, and allow you to check
        and uncheck which environments to install the designer for.</p>
      <h3> Express Edition Limitations</h3>
      <p>All Express Editions (except Visual Web Developer) are hard-coded to only allow you to design for Jet and Sql Server Database Files.&nbsp; The only way for SQLite
        to install its designer is to temporarily replace one of the existing "approved"
        designers.&nbsp; Therefore, when you install the SQLite designer for one of these
        express editions, it will temporarily replace the Microsoft Access designer.&nbsp;
        You can revert back to the Access designer simply by re-running the install.exe
        program and un-checking the boxes.</p>

      <p>
        SQLite's version of the ALTER TABLE command allows the user to rename or add a new
        column to an existing table. It is not possible to remove a column from a table.
      </p>
      <p>
        The RENAME TO syntax is used to rename the table identified by <i>[database-name.]table-name</i>
        to <i>new-table-name</i>. This command cannot be used to move a table between attached
        databases, only to rename a table within the same database.</p>
      <p>
        If the table being renamed has triggers or indices, then these remain attached to
        the table after it has been renamed. However, if there are any view definitions,
        or statements executed by triggers that refer to the table being renamed, these
        are not automatically modified to use the new table name. If this is required, the
        triggers or view definitions must be dropped and recreated to use the new table
        name by hand.
      </p>
      <p>
        The ADD [COLUMN] syntax is used to add a new column to an existing table. The new
        column is always appended to the end of the list of existing columns. <i>Column-def</i>
        may take any of the forms permissable in a CREATE TABLE statement, with the following
        restrictions:
      </p>
      <ul>
        <li>The column may not have a PRIMARY KEY or UNIQUE constraint. </li>
        <li>The column may not have a default value of CURRENT_TIME, CURRENT_DATE or CURRENT_TIMESTAMP.
        </li>
        <li>If a NOT NULL constraint is specified, then the column must have a default value
          other than NULL. </li>
      </ul>
      <p>
        The execution time of the ALTER TABLE command is independent of the amount of data
        in the table. The ALTER TABLE command runs as quickly on a table with 10 million
        rows as it does on a table with 1 row.
      </p>
      <p>
        After ADD COLUMN has been run on a database, that database will not be readable
        by SQLite version 3.1.3 and earlier until the database is <a href="lang_vacuum.html">
          VACUUM</a>ed.</p>

        The ANALYZE command gathers statistics about indices and stores them in a special
        tables in the database where the query optimizer can use them to help make better
        index choices. If no arguments are given, all indices in all attached databases
        are analyzed. If a database name is given as the argument, all indices in that one
        database are analyzed. If the argument is a table name, then only indices associated
        with that one table are analyzed.</p>
      <p>
        The initial implementation stores all statistics in a single table named <b>sqlite_stat1</b>.
        Future enhancements may create additional tables with the same name pattern except
        with the "1" changed to a different digit. The <b>sqlite_stat1</b> table cannot be <a href="lang_droptable.html">DROP</a>ped, but all the content can be <a href="lang_delete.html">
          DELETE</a>d which has the same effect.</p>

      <p>
        The ATTACH DATABASE statement adds another database file to the current database
        connection. If the filename contains punctuation characters it must be quoted. The
        names 'main' and 'temp' refer to the main database and the database used for temporary
        tables. These cannot be detached. Attached databases are removed using the <a href="lang_detach.html">
          DETACH DATABASE</a> statement.</p>
      <p>
        You can read from and write to an attached database and you can modify the schema
        of the attached database. This is a new feature of SQLite version 3.0. In SQLite
        2.8, schema changes to attached databases were not allowed.</p>
      <p>
        You cannot create a new table with the same name as a table in an attached database,
        but you can attach a database which contains tables whose names are duplicates of
        tables in the main database. It is also permissible to attach the same database
        file multiple times.</p>
      <p>
        Tables in an attached database can be referred to using the syntax <i>database-name.table-name</i>.
        If an attached table doesn't have a duplicate table name in the main database, it
        doesn't require a database name prefix. When a database is attached, all of its
        tables which don't have duplicate names become the default table of that name. Any
        tables of that name attached afterwards require the table prefix. If the default
        table of a given name is detached, then the last table of that name attached becomes
        the new default.</p>
      <p>
        Transactions involving multiple attached databases are atomic, assuming that the
        main database is not ":memory:". If the main database is ":memory:" then transactions
        continue to be atomic within each individual database file. But if the host computer
        crashes in the middle of a COMMIT where two or more database files are updated,
        some of those files might get the changes where others might not. Atomic commit
        of attached databases is a new feature of SQLite version 3.0. In SQLite version
        2.8, all commits to attached databases behaved as if the main database were ":memory:".
      </p>
      <p>
        There is a compile-time limit of 10 attached database files.</p>

      <p>
        Comments aren't SQL commands, but can occur in SQL queries. They are treated as
        whitespace by the parser. They can begin anywhere whitespace can be found, including
        inside expressions that span multiple lines.
      </p>
      <p>
        SQL comments only extend to the end of the current line.</p>
      <p>
        C comments can span any number of lines. If there is no terminating delimiter, they
        extend to the end of the input. This is not treated as an error. A new SQL statement
        can begin on a line after a multiline comment ends. C comments can be embedded anywhere
        whitespace can occur, including inside expressions, and in the middle of
          other SQL
        statements. C comments do not nest. SQL comments inside a C comment will be ignored.

      <p>
        The ON CONFLICT clause is not a separate SQL command. It is a non-standard clause
        that can appear in many
          other SQL commands. It is given its own section in this
        document because it is not part of standard SQL and therefore might not be familiar.</p>
      <p>
        The syntax for the ON CONFLICT clause is as shown above for the CREATE TABLE command.
        For the INSERT and UPDATE commands, the keywords "ON CONFLICT" are replaced by "OR",
        to make the syntax seem more natural. For example, instead of "INSERT ON CONFLICT
        IGNORE" we have "INSERT OR IGNORE". The keywords change but the meaning of the clause
        is the same either way.</p>
      <p>
        The ON CONFLICT clause specifies an algorithm used to resolve constraint conflicts.
        There are five choices: ROLLBACK, ABORT, FAIL, IGNORE, and REPLACE. The default
        algorithm is ABORT. This is what they mean:</p>
      <dl>
        <dt><b>ROLLBACK</b> </dt>
        <dd>
          <p>
            When a constraint violation occurs, an immediate ROLLBACK occurs, thus ending the
            current transaction, and the command aborts with a return code of SQLITE_CONSTRAINT.
            If no transaction is active (other than the implied transaction that is created
            on every command) then this algorithm works the same as ABORT.</p>
        </dd>
        <dt><b>ABORT</b> </dt>
        <dd>
          <p>
            When a constraint violation occurs, the command backs out any prior changes it might
            have made and aborts with a return code of SQLITE_CONSTRAINT. But no ROLLBACK is
            executed so changes from prior commands within the same transaction are preserved.
            This is the default behavior.</p>
        </dd>
        <dt><b>FAIL</b> </dt>
        <dd>
          <p>
            When a constraint violation occurs, the command aborts with a return code SQLITE_CONSTRAINT.
            But any changes to the database that the command made prior to encountering the
            constraint violation are preserved and are not backed out. For example, if an UPDATE
            statement encountered a constraint violation on the 100th row that it attempts to
            update, then the first 99 row changes are preserved but changes to rows 100 and
            beyond never occur.</p>
        </dd>
        <dt><b>IGNORE</b> </dt>
        <dd>
          <p>
            When a constraint violation occurs, the one row that contains the constraint violation
            is not inserted or changed. But the command continues executing normally. Other
            rows before and after the row that contained the constraint violation continue to
            be inserted or updated normally. No error is returned.</p>
        </dd>
        <dt><b>REPLACE</b> </dt>
        <dd>
          <p>
            When a UNIQUE constraint violation occurs, the pre-existing rows that are causing
            the constraint violation are removed prior to inserting or updating the current
            row. Thus the insert or update always occurs. The command continues executing normally.
            No error is returned. If a NOT NULL constraint violation occurs, the NULL value
            is replaced by the default value for that column. If the column has no default value,
            then the ABORT algorithm is used. If a CHECK constraint violation occurs then the
            IGNORE algorithm is used.</p>
          <p>
            When this conflict resolution strategy deletes rows in order to satisfy a constraint,
            it does not invoke delete triggers on those rows. This behavior might change in
            a future release.</p>
        </dd>
      </dl>
      <p>
        The algorithm specified in the OR clause of a INSERT or UPDATE overrides any algorithm
        specified in a CREATE TABLE. If no algorithm is specified anywhere, the ABORT algorithm
        is used.</p>

        The CREATE INDEX command consists of the keywords "CREATE INDEX" followed by the
        name of the new index, the keyword "ON", the name of a previously created table
        that is to be indexed, and a parenthesized list of names of columns in the table
        that are used for the index key. Each column name can be followed by one of the
        "ASC" or "DESC" keywords to indicate sort order, but the sort order is ignored in
        the current implementation. Sorting is always done in ascending order.</p>
      <p>
        The COLLATE clause following each column name defines a collating sequence used
        for text entires in that column. The default collating sequence is the collating
        sequence defined for that column in the CREATE TABLE statement. Or if no collating
        sequence is otherwise defined, the built-in BINARY collating sequence is used.</p>
      <p>
        There are no arbitrary limits on the number of indices that can be attached to a
        single table, nor on the number of columns in an index.</p>
      <p>
        If the UNIQUE keyword appears between CREATE and INDEX then duplicate index entries
        are not allowed. Any attempt to insert a duplicate entry will result in an error.</p>
      <p>
        The exact text of each CREATE INDEX statement is stored in the <b>sqlite_master</b>
        or <b>sqlite_temp_master</b> table, depending on whether the table being indexed
        is temporary. Every time the database is opened, all CREATE INDEX statements are
        read from the <b>sqlite_master</b> table and used to regenerate
        SQLite's internal
        representation of the index layout.</p>
      <p>
        If the optional IF NOT EXISTS clause is present and another index with the same name aleady exists, then this command becomes a no-op.</p>
      <p>
        Indexes are removed with the <a href="lang_dropindex.html">DROP INDEX</a> command.</p>

        A CREATE TABLE statement is basically the keywords "CREATE TABLE" followed by the
        name of a new table and a parenthesized list of column definitions and constraints.
        The table name can be either an identifier or a string. Tables names that begin
        with "<b>sqlite_</b>" are reserved for use by the engine.</p>

        Each column definition is the name of the column followed by the datatype for that
        column, then one or more optional column constraints. The datatype for the column
        does not restrict what data may be put in that column. See <a href="http://www.sqlite.org/datatype3.html">
          Datatypes In SQLite Version 3</a> for additional information. The UNIQUE constraint
        causes an index to be created on the specified columns. This index must contain
        unique keys. The COLLATE clause specifies what text <a href="http://www.sqlite.org/datatype3.html#collation">
          collating function</a> to use when comparing text entries for the column. The
        built-in BINARY collating function is used by default.
      </p>
      <p>
        The DEFAULT constraint specifies a default value to use when doing an INSERT. The
        value may be NULL, a string constant or a number. Starting with version 3.1.0, the
        default value may also be one of the special case-independant keywords CURRENT_TIME, CURRENT_DATE or CURRENT_TIMESTAMP. If the value is NULL, a string constant or number,
        it is literally inserted into the column whenever an INSERT statement that does
        not specify a value for the column is executed. If the value is CURRENT_TIME, CURRENT_DATE
        or CURRENT_TIMESTAMP, then the current UTC date and/or time is inserted into the
        columns. For CURRENT_TIME, the format is HH:MM:SS. For CURRENT_DATE, YYYY-MM-DD.
        The format for CURRENT_TIMESTAMP is "YYYY-MM-DD HH:MM:SS".
      </p>
      <p>
        Specifying a PRIMARY KEY normally just creates a UNIQUE index on the corresponding
        columns. However, if primary key is on a single column that has datatype INTEGER,
        then that column is used internally as the actual key of the B-Tree for the table.
        This means that the column may only hold unique integer values. (Except for this
        one case, SQLite ignores the datatype specification of columns and allows any kind
        of data to be put in a column regardless of its declared datatype.) If a table does
        not have an INTEGER PRIMARY KEY column, then the B-Tree key will be a automatically
        generated integer. The B-Tree key for a row can always be accessed using one of
        the special names "<b>ROWID</b>", "<b>OID</b>", or "<b>_ROWID_</b>". This is true
        regardless of whether or not there is an INTEGER PRIMARY KEY. An INTEGER PRIMARY
        KEY column man also include the keyword AUTOINCREMENT. The AUTOINCREMENT keyword
        modified the way that B-Tree keys are automatically generated. Additional detail
        on automatic B-Tree key generation is available <a href="http://www.sqlite.org/autoinc.html">
          separately</a>.</p>
      <p>
        If the "TEMP" or "TEMPORARY" keyword occurs in between "CREATE" and "TABLE" then
        the table that is created is only visible within that same database connection and
        is automatically deleted when the database connection is closed. Any indices created
        on a temporary table are also temporary. Temporary tables and indices are stored
        in a separate file distinct from the main database file.</p>
      <p>
        If a &lt;database-name&gt; is specified, then the table is created in the named
        database. It is an error to specify both a &lt;database-name&gt; and the TEMP keyword,
        unless the &lt;database-name&gt; is "temp". If no database name is specified, and
        the TEMP keyword is not present, the table is created in the main database.</p>
      <p>
        The optional conflict-clause following each constraint allows the specification
        of an alternative default constraint conflict resolution algorithm for that constraint. The default is abort ABORT. Different constraints within the same table may have
        different default conflict resolution algorithms. If an COPY, INSERT, or UPDATE
        command specifies a different conflict resolution algorithm, then that algorithm
        is used in place of the default algorithm specified in the CREATE TABLE statement.
        See the section titled <a href="lang_conflict.html">ON CONFLICT</a> for additional
        information.</p>
      <p>
        CHECK constraints are supported as of version 3.3.0. Prior to version 3.3.0, CHECK
        constraints were parsed but not enforced.</p>
      <p>
        There are no arbitrary limits on the number of columns or on the number of constraints
        in a table. The total amount of data in a single row is limited to about 1 megabytes
        in version 2.8. In version 3.0 there is no arbitrary limit on the amount of data
        in a row.</p>
      <p>
        The CREATE TABLE AS form defines the table to be the result set of a query. The
        names of the table columns are the names of the columns in the result.</p>
      <p>
        The exact text of each CREATE TABLE statement is stored in the <b>sqlite_master</b>
        table. Every time the database is opened, all CREATE TABLE statements are read from
        the <b>sqlite_master</b> table and used to regenerate
        SQLite's internal representation
        of the table layout. If the original command was a CREATE TABLE AS then then an
        equivalent CREATE TABLE statement is synthesized and store in <b>sqlite_master</b>
        in place of the original command. The text of CREATE TEMPORARY TABLE statements
        are stored in the <b>sqlite_temp_master</b> table.
      </p>
      <p>
        If the optional IF NOT EXISTS clause is present and another table with the same
        name aleady exists, then this command becomes a no-op.</p>
      <p>
        Tables are removed using the <a href="lang_droptable.html">DROP TABLE</a> statement.

      <p>
        The CREATE TRIGGER statement is used to add triggers to the database schema. Triggers
        are database operations (the <i>trigger-action</i>) that are automatically performed
        when a specified database event (the <i>database-event</i>) occurs.
      </p>
      <p>
        A trigger may be specified to fire whenever a DELETE, INSERT or UPDATE of a particular
        database table occurs, or whenever an UPDATE of one or more specified columns of
        a table are updated.</p>
      <p>
        At this time SQLite supports only FOR EACH ROW triggers, not FOR EACH STATEMENT
        triggers. Hence explicitly specifying FOR EACH ROW is optional. FOR EACH ROW implies
        that the SQL statements specified as <i>trigger-steps</i> may be executed (depending
        on the WHEN clause) for each database row being inserted, updated or deleted by
        the statement causing the trigger to fire.</p>
      <p>
        Both the WHEN clause and the <i>trigger-steps</i> may access elements of the row
        being inserted, deleted or updated using references of the form "NEW.<i>column-name</i>"
        and "OLD.<i>column-name</i>", where <i>column-name</i> is the name of a column from the table that the trigger is associated with. OLD and NEW references may only be
        used in triggers on <i>trigger-event</i>s for which they are relevant, as follows:</p>
      <p>
        <table border="0" cellpadding="10">
          <tr>
            <td align="right" valign="top" width="120">
              <i>INSERT</i></td>
            <td valign="top">
              NEW references are valid</td>
          </tr>
          <tr>
            <td align="right" valign="top" width="120">
              <i>UPDATE</i></td>
            <td valign="top">
              NEW and OLD references are valid</td>
          </tr>
          <tr>
            <td align="right" valign="top" width="120">
              <i>DELETE</i></td>
            <td valign="top">
              OLD references are valid</td>
          </tr>
        </table>
      </p>
      <p>
      </p>
      <p>
        If a WHEN clause is supplied, the SQL statements specified as <i>trigger-steps</i>
        are only executed for
        rows for which the WHEN clause is true. If no WHEN clause
        is supplied, the SQL statements are executed for all rows.</p>
      <p>
        The specified <i>trigger-time</i> determines when the <i>trigger-steps</i> will
        be executed relative to the insertion, modification or removal of the associated
        row.</p>
      <p>
        An ON CONFLICT clause may be specified as part of an UPDATE or INSERT <i>trigger-step</i>.
        However if an ON CONFLICT clause is specified as part of the statement causing the
        trigger to fire, then this conflict handling policy is used instead.</p>
      <p>
        Triggers are automatically dropped when the table that they are associated with
        is dropped.</p>
      <p>
        Triggers may be created on views, as well as ordinary tables, by specifying INSTEAD
        OF in the CREATE TRIGGER statement. If one or more ON INSERT, ON DELETE or ON UPDATE
        triggers are defined on a view, then it is not an error to execute an INSERT, DELETE
        or UPDATE statement on the view, respectively. Thereafter, executing an INSERT,
        DELETE or UPDATE on the view causes the associated triggers to fire. The real tables
        underlying the view are not modified (except possibly explicitly, by a trigger program).</p>
      <p>
        <b>Example:</b></p>
      <p>
        Assuming that customer records are stored in the "customers" table, and that order
        records are stored in the "orders" table, the following trigger ensures that all
        associated orders are redirected when a customer changes his or her address:</p>
      <blockquote>
        <pre>
CREATE TRIGGER update_customer_address UPDATE OF address ON customers 
  BEGIN
    UPDATE orders SET address = new.address WHERE customer_name = old.name;
  END;
</pre>
      </blockquote>
      <p>
        With this trigger installed, executing the statement:</p>
      <blockquote>
        <pre>
UPDATE customers SET address = '1 Main St.' WHERE name = 'Jack Jones';
</pre>
      </blockquote>
      <p>
        causes the following to be automatically executed:</p>
      <blockquote>
        <pre>
UPDATE orders SET address = '1 Main St.' WHERE customer_name = 'Jack Jones';
</pre>
      </blockquote>
      <p>
        Note that currently, triggers may behave oddly when created on tables with INTEGER
        PRIMARY KEY fields. If a BEFORE trigger program modifies the INTEGER PRIMARY KEY
        field of a row that will be subsequently updated by the statement that causes the
        trigger to fire, then the update may not occur. The workaround is to declare the
        table with a PRIMARY KEY column instead of an INTEGER PRIMARY KEY column.</p>
      <p>
        A special SQL function RAISE() may be used within a trigger-program, with the following
        syntax</p>
      <p>
        <table cellpadding="10">
          <tr>
            <td align="right" width="1%" nowrap>
              <i><font color="#ff3434">raise-function</font></i> ::=</td>
            <td>
              <b><font color="#2c2cf0">RAISE <big>(</big> ABORT<big>,</big> </font></b><i><font

                </b><big>|</big><b><font color="#2c2cf0">
                  <br />
                  RAISE <big>(</big> FAIL<big>,</big> </font></b><i><font color="#ff3434">error-message</font></i><b><font
                    color="#2c2cf0"> <big>)</big> </font></b><big>|</big><b><font color="#2c2cf0">
                      <br />
                      RAISE <big>(</big> ROLLBACK<big>,</big> </font></b><i><font color="#ff3434">error-message</font></i><b><font
                        color="#2c2cf0"> <big>)</big> </font></b><big>|</big><b><font color="#2c2cf0">
                          <br />
                          RAISE <big>(</big> IGNORE <big>)</big></font></b></td>
          </tr>
        </table>
      </p>
      <p>
        When one of the first three forms is called during trigger-program execution, the
        specified ON CONFLICT processing is performed (either ABORT, FAIL or ROLLBACK) and
        the current query terminates. An error code of SQLITE_CONSTRAINT is returned to
        the user, along with the specified error message.</p>
      <p>
        When RAISE(IGNORE) is called, the remainder of the current trigger program, the
        statement that caused the trigger program to execute and any subsequent trigger
        programs that would of been executed are abandoned. No database changes are rolled
        back. If the statement that caused the trigger program to execute is itself part
        of a trigger program, then that trigger program resumes execution at the beginning
        of the next step.
      </p>
      <p>
        Triggers are removed using the <a href="lang_droptrigger.html">DROP TRIGGER</a>
        statement.</p>

        The CREATE VIEW command assigns a name to a pre-packaged <a href="lang_select.html">
          SELECT</a> statement. Once the view is created, it can be used in the FROM clause
        of another SELECT in place of a table name. 
      </p>
      <p>
        If the "TEMP" or "TEMPORARY" keyword occurs in between "CREATE" and "VIEW" then
        the view that is created is only visible to the process that opened the database
        and is automatically deleted when the database is closed.</p>
      <p>
        If a &lt;database-name&gt; is specified, then the view is created in the named database.
        It is an error to specify both a &lt;database-name&gt; and the TEMP keyword, unless
        the &lt;database-name&gt; is "temp". If no database name is specified, and the TEMP
        keyword is not present, the table is created in the main database.</p>
      <p>
        You cannot COPY, DELETE, INSERT or UPDATE a view. Views are read-only in SQLite.
        However, in many cases you can use a <a href="lang_createtrigger.html">TRIGGER</a>
        on the view to accomplish the same thing. Views are removed with the <a href="lang_dropview.html">
          DROP VIEW</a> command.</p>

      <p>
        A virtual table is an interface to an external storage or computation engine that
        appears to be a table but does not actually store information in the database file.</p>
      <p>
        In general, you can do anything with a virtual table that can be done with an ordinary
        table, except that you cannot create triggers on a virtual table. Some virtual table
        implementations might impose additional restrictions. For example, many virtual
        tables are read-only.</p>
      <p>
        The &lt;module-name&gt; is the
        name of an object that implements the virtual table.
        The &lt;module-name&gt; must be registered with the SQLite database connection using
        <a href="capi3ref.html#sqlite3_create_module">sqlite3_create_module</a> prior to
        issuing the CREATE VIRTUAL TABLE statement. The module takes zero or more comma-separated
        arguments. The arguments can be just about any text as long as it has balanced parentheses.
        The argument syntax is sufficiently general that the arguments can be made to appear
        as column definitions in a traditional <a href="lang_createtable.html">CREATE TABLE</a>
        statement. SQLite passes the module arguments directly to the module without any
        interpretation. It is the responsibility of the module implementation to parse and
        interpret its own arguments.</p>
      <p>
        A virtual table is destroyed using the ordinary <a href="lang_droptable.html">DROP
          TABLE</a> statement. There is no DROP VIRTUAL TABLE statement.</p>

      <h1 class="heading">Date and Time Functions</h1>
<p>Five date and time functions are available, as follows:

<p><ol>
<li>date( <i>timestring</i>, <i>modifier</i>, <i>modifier</i>, ...)
<li>time( <i>timestring</i>, <i>modifier</i>, <i>modifier</i>, ...)
<li>datetime( <i>timestring</i>, <i>modifier</i>, <i>modifier</i>, ...)
<li>julianday( <i>timestring</i>, <i>modifier</i>, <i>modifier</i>, ...)
<li>strftime( <i>format</i>, <i>timestring</i>, <i>modifier</i>, <i>modifier</i>, ...)
</ol>

<p>All five functions take a time string as an argument.  This
time string may be followed by zero or more modifiers.  The
<b>strftime()</b> function also takes a format string as its first
argument.

<p>The <b>date()</b> function returns the date in this format: YYYY-MM-DD.
The <b>time()</b> function returns the time as HH:MM:SS.  The <b>datetime()</b>
function returns &quot;YYYY-MM-DD HH:MM:SS&quot;.  The <b>julianday()</b> function
returns the number of days since noon in Greenwich on November 24, 4714 B.C.
The julian day number is the preferred internal representation of
dates.  The <b>strftime()</b> routine returns the date formatted according
to the format string specified as the first argument.  The format string
supports most, but not all, of the more common substitutions found in
the strftime() function from the standard C library:

<p><pre>
   %d  day of month
   %f  ** fractional seconds  SS.SSS
   %H  hour 00-24
   %j  day of year 001-366
   %J  ** Julian day number
   %m  month 01-12
   %M  minute 00-59
   %s  seconds since 1970-01-01
   %S  seconds 00-59
   %w  day of week 0-6  sunday==0
   %W  week of year 00-53
   %Y  year 0000-9999
   %%  %
</pre>

<p>The %f and %J conversions are new.  Notice that all of the other four
functions could be expressed in terms of <b>strftime()</b>.

<p><pre>
   date(...)      -&gt;  strftime(&quot;%Y-%m-%d&quot;, ...)
   time(...)      -&gt;  strftime(&quot;%H:%M:%S&quot;, ...)
   datetime(...)  -&gt;  strftime(&quot;%Y-%m-%d %H:%M:%S&quot;, ...)
   julianday(...) -&gt;  strftime(&quot;%J&quot;, ...)
</pre>

<p>The only reasons for providing functions other than <b>strftime()</b> is for
convenience and for efficiency.

<p><b>Time Strings</b>

<p>A time string can be in any of the following formats:

<p><ol>
<li>YYYY-MM-DD
<li>YYYY-MM-DD HH:MM
<li>YYYY-MM-DD HH:MM:SS
<li>YYYY-MM-DD HH:MM:SS.SSS
<li>YYYY-MM-DDTHH:MM
<li>YYYY-MM-DDTHH:MM:SS
<li>YYYY-MM-DDTHH:MM:SS.SSS
<li>HH:MM
<li>HH:MM:SS
<li>HH:MM:SS.SSS
<li>now
<li>DDDD.DDDD
</ol>

<p>In formats 5 through 7, the &quot;T&quot; is a literal character separating the date and the time, as required by the ISO-8601 standard. These formats are supported in SQLite 3.2.0 and later.
Formats 8 through 10 that specify only a time assume a date of 2000-01-01.
Format 11, the string 'now', is converted into the current date and time.
Universal Coordinated Time (UTC) is used.
Format 12 is the julian day number expressed as a floating point value.

<p><b>Modifiers</b>

<p>The time string can be followed by zero or more modifiers that alter the
date or alter the interpretation of the date.  The available modifiers
are as follows.

<p><ol>
<li>NNN days
<li>NNN hours
<li>NNN minutes
<li>NNN.NNNN seconds
<li>NNN months  (see <a href="tktview?tn=551">#551</a>
 and <a href="chngview?cn=1163">[1163]</a>
)
<li>NNN years  (see <a href="tktview?tn=551">#551</a>
 and <a href="chngview?cn=1163">[1163]</a>
)
<li>start of month
<li>start of year
<li>start of week  (withdrawn -- will not be implemented)
<li>start of day
<li>weekday N  (see <a href="tktview?tn=551">#551</a>
 and <a href="chngview?cn=1163">[1163]</a>
)
<li>unixepoch
<li>localtime
<li>utc
</ol>

<p>The first six modifiers (1 through 6) simply add the specified amount
of time to the date specified by the preceding timestring.

<p>The &quot;start of&quot; modifiers (7 through 10) shift the date backwards to
the beginning of the current month, year or day.

<p>The &quot;weekday&quot; modifier advances the date forward to the next date where
the weekday number is N.  Sunday is 0, Monday is 1, and so forth.

<p>The &quot;unixepoch&quot; modifier (12) only works if it immediately follows
a timestring in the DDDDDDDDDD format.  This modifier causes the DDDDDDDDDD
to be interpreted not as a julian day number as it normally would be, but
as the number of seconds since 1970.  This modifier allows unix-based times
to be converted to julian day numbers easily.

<p>The &quot;localtime&quot; modifier (13) adjusts the previous time string so that it
displays the correct local time.  &quot;utc&quot; undoes this.

<p><b>Examples</b>

<p>Compute the current date.

<p><pre>
  SELECT date('now');
</pre>

<p>Compute the last day of the current month.

<p><pre>
  SELECT date('now','start of month','+1 month','-1 day');
</pre>

<p>Compute the date and time given a unix timestamp 1092941466.

<p><pre>
  SELECT datetime(1092941466, 'unixepoch');
</pre>

<p>Compute the date and time given a unix timestamp 1092941466, and compensate for your local timezone.

<p><pre>
  SELECT datetime(1092941466, 'unixepoch', 'localtime');
</pre>

<p>Compute the current unix timestamp.

<p><pre>
  SELECT strftime('%s','now');
</pre>

<p>Compute the number of days since the battle of Hastings.

<p><pre>
  SELECT julianday('now') - julianday('1066-10-14','gregorian');
</pre>

<p>Compute the number of seconds between two dates:

<p><pre>
  SELECT julianday('now')*86400 - julianday('2004-01-01 02:34:56')*86400;
</pre>

<p>Compute the date of the first Tuesday in October (January + 9) for the current
year.

<p><pre>
  SELECT date('now','start of year','+9 months','weekday 2');
</pre>

<p><b>Caveats And Bugs</b>

<p>The computation of local time depends heavily on the whim of local
politicians and is thus difficult to get correct for all locales.  In
this implementation, the standard C library function localtime() is
used to assist in the calculation of local time.
Note that localtime() is not
threadsafe, so use of the &quot;localtime&quot; modifier is not threadsafe.
Also, the localtime() C function normally only works for years between
1970 and 2037.  For dates outside this range, SQLite attempts to
map the year into an equivalent year within this range, do the
calculation, then map the year back.

<p><i>Please surround uses of localtime() with sqliteOsEnterMutex() and sqliteOsLeaveMutex() so threads
using SQLite are protected, at least!
-- e</i>  It is so. --drh

<p><i>[Consider instead, using localtime_r which is reentrant and may be used
*without* expensive mutex locking. Although non-standard it's available
on most Unixes --hauk]</i> But it is not available on windows, as far as I
am aware. --drh On windows localtime() is thread-safe if the MT C runtime is used. The MT runtime uses thread-local storage for the static variables, the kind functions use.--gr <i>[What about using localtime_r, and on systems where it
is unavailable defining it as sqliteOsEnterMutext() ; locatime() ; sqliteOsLeaveMutex()
so that non-windows systems get the maximum advantage, with almost zero
code impact?]</i> The autoconfigury and patch for localtime_r is here: <font color="#a0a0a0">&curren;</font><a href="http://www.sqlite.org/cvstrac/tktview?tn=1906">http://www.sqlite.org/cvstrac/tktview?tn=1906</a> . I'm curious why this obvious fix is not applied. gmtime() also suffers from this same threadsafety problem.

<p>Date computations do not give correct results for dates before Julian
day number 0 (-4713-11-24 12:00:00).

<p>All internal computations assume the Gregorian calendar system.

<p><hr>
<i>An anonymous user adds:</i> <br>

For my use I added new functions and functionalities to the date functions that
come with the sqlite 3.3.0 (can be used in older versions as well with small effort).

<p>In main lines they are as follows:

<p><ol>
<li>NNN days
<li>NNN hours
<li>NNN minutes
<li>NNN.NNNN seconds
<li>NNN months  (see <a href="tktview?tn=551">#551</a>
 and <a href="chngview?cn=1163">[1163]</a>
)
<li>NNN years  (see <a href="tktview?tn=551">#551</a>
 and <a href="chngview?cn=1163">[1163]</a>
)
<li>start of month
<li>start of year
<li>start of week  (!!! implemented)
<li>start of day
<li>weekday N  (see <a href="tktview?tn=551">#551</a>
 and <a href="chngview?cn=1163">[1163]</a>
)
<li>unixepoch
<li>localtime
<li>utc
<li>julian  (not implemented as of 2004-01-05)
<li>gregorian  (not implemented as of 2004-01-05)
<li>start of minute
<li>start of hour
<li>end of minute
<li>end of hour
<li>end of day
<li>end of week
<li>end of month
<li>end of year
<li>group seconds by
<li>group minutes by
<li>group hours by
<li>group days by
<li>group weeks by
<li>group months by
<li>group years by
</ol>

<p>The &quot;start of&quot; modifiers (7 through 10 and 17 through 18) shift the date backwards to the beginning of the current minute, hour, week, month, year or day.

<p>The &quot;end of&quot; modifiers (19 through 24) shift the date forwards to
the end of the current minute, hour, week, month, year or day.

<p>The &quot;group * by&quot; modifiers (25 through 31) round the date to the closest backward multiple supplied, with some limitations, to the current seconds (1 through 30), minutes (1 through 30), hours (1 through 12), days (1 through 15), weeks (1 through 26), months (1 through 6), years (1 through 100), these limitations are due to dont complicate the calculations when a multiple can span beyound the unit modified.

<p>Ex:

<p>SELECT datetime('2006-02-04 20:09:23','group hours by 3'); =&gt; '2006-02-04 18:00:00'

<p>SELECT datetime('2006-02-05 20:09:23','group days by 3'); =&gt; '2006-02-04 00:00:00'

<p>New functions &quot;week_number(date)&quot; returns the week number of the year on the supplied date parameter, &quot;datetime2seconds(datetime)&quot; return the number of seconds from the supplied datetime parameter.

        The DELETE command is used to remove records from a table. The command consists
        of the "DELETE FROM" keywords followed by the
        name of the table from which records
        are to be removed.
      </p>
      <p>
        Without a WHERE clause, all rows of the table are removed. If a WHERE clause is
        supplied, then only those rows that match the expression are removed.</p>

        This statement detaches an additional database connection previously attached using
        the <a href="lang_attach.html">ATTACH DATABASE</a> statement. It is possible to have the same database file attached multiple times using different names, and detaching
        one connection to a file will leave the others intact.</p>
      <p>
        This statement will fail if SQLite is in the middle of a transaction.</p>

        The DROP INDEX statement removes an index added with the <a href="lang_createindex.html">
          CREATE INDEX</a> statement. The index named is completely removed from the disk.
        The only way to recover the index is to reenter the appropriate CREATE INDEX command.</p>
      <p>
        The DROP INDEX statement does not reduce the size of the database file in the default
        mode. Empty space in the database is retained for later INSERTs. To remove free
        space in the database, use the <a href="lang_vacuum.html">
          VACUUM</a> command. If
        AUTOVACUUM mode is enabled for a database then space will be freed automatically by DROP INDEX.</p>

        The DROP TABLE statement removes a table added with the <a href="#createtable">CREATE TABLE</a> statement. The
        name specified is the table name. It is completely removed
        from the database schema and the disk file. The table can not be recovered. All
        indices associated with the table are also deleted.</p>
      <p>
        The DROP TABLE statement does not reduce the size of the database file in the default
        mode. Empty space in the database is retained for later INSERTs. To remove free
        space in the database, use the <a href="lang_vacuum.html">
          VACUUM</a> command. If
        AUTOVACUUM mode is enabled for a database then space will be freed automatically by DROP TABLE.</p>
      <p>
        The optional IF EXISTS clause suppresses the error that would normally result if the table does not exist.</p>

        The EXPLAIN command modifier is a non-standard extension. The idea comes from a similar command found in PostgreSQL, but the operation is completely different.</p>
      <p>
        If the EXPLAIN keyword appears before any
          other SQLite SQL command then instead
        of actually executing the command, the SQLite library will report back the sequence
        of virtual machine instructions it would have used to execute the command had the
        EXPLAIN keyword not been present. For additional information about virtual machine
        instructions see the <a href="http://www.sqlite.org/arch.html">architecture description</a>
        or the documentation on <a href="http://www.sqlite.org/opcode.html">available opcodes</a>
        for the virtual machine.</p>

        This section is different from the others. Most other sections of this document
        talks about a particular SQL command. This section does not talk about a standalone
        command but about "expressions" which are subcomponents of most other commands.</p>
      <p>
        SQLite understands the following binary operators, in order from highest to lowest
        precedence:</p>
      <blockquote>
        <pre><font color="#2c2cf0"><big>|| * / % + - &lt;&lt; &gt;&gt; &amp; | &lt; &lt;= &gt;
  &gt;= = == != &lt;&gt; </big>IN AND OR</font>
</pre>
      </blockquote>
      <p>
        Supported unary operators are these:</p>
      <blockquote>
        <pre><font color="#2c2cf0"><big>- + ! ~ NOT</big></font>
</pre>
      </blockquote>
      <p>
        The unary operator [Operator +] is a no-op. It can be applied to strings, numbers,
        or blobs and it always gives as its result the value of the operand.</p>
      <p>
        Note that there are two variations of the equals and not equals operators. Equals
        can be either <font color="#2c2cf0"><big>=</big></font> or <font color="#2c2cf0"><big>
          ==</big></font>. The non-equals operator can be either <font color="#2c2cf0"><big>
            !=</big></font> or <font color="#2c2cf0"><big>&lt;&gt;</big></font>. The <font color="#2c2cf0">
              <big>||</big></font> operator is "concatenate" - it joins together the two
        strings of its operands. The operator <font color="#2c2cf0"><big>%</big></font>
        outputs the remainder of its left operand modulo its right operand.</p>
      <p>
        The result of any binary operator is a numeric value, except for the <font color="#2c2cf0">
          <big>||</big></font> concatenation operator which gives a string result.</p>
      <a name="literal_value"></a>
      <p>
        A literal value is an integer number or a floating point number. Scientific notation
        is supported. The "." character is always used as the decimal point even if the
        locale setting specifies "," for this role - the use of "," for the decimal point
        would result in syntactic ambiguity. A string constant is formed by enclosing the
        string in single quotes ('). A single quote within the string can be encoded by
        putting two single quotes in a row - as in Pascal. C-style escapes using the backslash
        character are not supported because they are not standard SQL. BLOB literals are
        string literals containing hexadecimal data and preceded by a single "x" or "X"
        character. For example:</p>
      <blockquote>
        <pre>X'53514697465'
</pre>
      </blockquote>
      <p>
        A literal value can also be the token "NULL".
      </p>
      <p>
        A parameter specifies a placeholder in the expression for a literal value that is
        filled in at runtime using the <a href="capi3ref.html#sqlite3_bind_int">sqlite3_bind</a>
        API. Parameters can take several forms:

        Parameters that are not assigned values using <a href="capi3ref.html#sqlite3_bind_int">
          sqlite3_bind</a> are treated as NULL.</p>
      <a name="like"></a>
      <p>
        The LIKE operator does a pattern matching comparison. The operand to the right contains
        the pattern, the left hand operand contains the string to match against the pattern.
        A percent symbol <font color="#2c2cf0"><big>%</big></font> in the pattern matches
        any sequence of zero or more characters in the string. An underscore <font color="#2c2cf0">
          <big>_</big></font> in the pattern matches any single character in the string.
        Any other character matches itself or it's lower/upper case equivalent (i.e. case-insensitive
        matching). (A bug: SQLite only understands upper/lower case for 7-bit Latin characters.
        Hence the LIKE operator is case sensitive for 8-bit iso8859 characters or UTF-8
        characters. For example, the expression <b>'a' LIKE 'A'</b> is TRUE but <b>'æ' LIKE
          'Æ'</b> is FALSE.).</p>
      <p>
        If the optional ESCAPE clause is present, then the expression following the ESCAPE
        keyword must evaluate to a string consisting of a single character. This character
        may be used in the LIKE pattern to include literal percent or underscore characters.
        The escape character followed by a percent symbol, underscore or itself matches
        a literal percent symbol, underscore or escape character in the string, respectively.
        The infix LIKE operator is implemented by calling the user function <a href="#likeFunc">
          like(<i>X</i>,<i>Y</i>)</a>.</p>
      <p>
        The LIKE operator is not case sensitive and will match upper case characters on
        one side against lower case characters on the other. (A bug: SQLite only understands
        upper/lower case for 7-bit Latin characters. Hence the LIKE operator is case sensitive
        for 8-bit iso8859 characters or UTF-8 characters. For example, the expression <b>'a'
          LIKE 'A'</b> is TRUE but <b>'æ' LIKE 'Æ'</b> is FALSE.).
      </p>
      <p>
      </p>
      <p>
        The infix LIKE operator is implemented by calling the user function <a href="#likeFunc">
          like(<i>X</i>,<i>Y</i>)</a>. If an ESCAPE clause is present, it adds a third parameter
        to the function call. If the functionality of LIKE can be overridden by defining
        an alternative implementation of the like() SQL function.</p>
      <p>
      </p>
      <a name="glob"></a>
      <p>
        The GLOB operator is similar to LIKE but uses the Unix file globbing syntax for
        its wildcards. Also, GLOB is case sensitive, unlike LIKE. Both GLOB and LIKE may
        be preceded by the NOT keyword to invert the sense of the test. The infix GLOB operator
        is implemented by calling the user function <a href="#globFunc">glob(<i>X</i>,<i>Y</i>)</a>
        and can be modified by overriding that function.</p>
      <a name="regexp"></a>
      <p>
        The REGEXP operator is a special syntax for the regexp() user function. No regexp()
        user function is defined by default and so use of the REGEXP operator will normally
        result in an error message. If a user-defined function named "regexp" is added at
        run-time, that function will be called in order to implement the REGEXP operator.</p>
      <a name="match"></a>
      <p>
        The MATCH operator is a special syntax for the match() user function. The default
        match() function implementation raises and exception and is not really useful for
        anything. But extensions can override the match() function with more helpful logic.</p>
      <p>
        A column name can be any of the names defined in the CREATE TABLE statement or one
        of the following special identifiers: "<b>ROWID</b>", "<b>OID</b>", or "<b>_ROWID_</b>".
        These special identifiers all describe the unique random integer key (the "row key")
        associated with every row of every table. The special identifiers only refer to
        the row key if the CREATE TABLE statement does not define a real column with the
        same name. Row keys act like read-only columns. A row key can be used anywhere a
        regular column can be used, except that you cannot change the value of a row key
        in an UPDATE or INSERT statement. "SELECT * ..." does not return the row key.</p>
      <p>
        SELECT statements can appear in expressions as either the right-hand operand of
        the IN operator, as a scalar quantity, or as the operand of an EXISTS operator.
        As a scalar quantity or the operand of an IN operator, the SELECT should have only
        a single column in its result. Compound SELECTs (connected with keywords like UNION
        or EXCEPT) are allowed. With the EXISTS operator, the columns in the result set
        of the SELECT are ignored and the expression returns TRUE if one or more rows exist
        and FALSE if the result set is empty. If no terms in the SELECT expression refer
        to value in the containing query, then the expression is evaluated once prior to
        any other processing and the result is reused as necessary. If the SELECT expression
        does contain variables from the outer query, then the SELECT is reevaluated every
        time it is needed.</p>
      <p>
        When a SELECT is the right operand of the IN operator, the IN operator returns TRUE
        if the result of the left operand is any of the values generated by the select.
        The IN operator may be preceded by the NOT keyword to invert the sense of the test.</p>
      <p>
        When a SELECT appears within an expression but is not the right operand of an IN
        operator, then the first row of the result of the SELECT becomes the value used
        in the expression. If the SELECT yields more than one result row, all rows after the first are ignored. If the SELECT yields no rows, then the value of the SELECT
        is NULL.</p>
      <p>
        A CAST expression changes the datatype of the
        <expr>
</expr>
        into the type specified by &lt;type&gt;. &lt;type&gt; can be any non-empty type
        name that is valid for the type in a column definition of a CREATE TABLE statement.</p>
      <p>
        Both simple and aggregate functions are supported. A simple function can be used
        in any expression. Simple functions return a result immediately based on their inputs.
        Aggregate functions may only be used in a SELECT statement. Aggregate functions
        compute their result across all rows of the result set.</p>

              unlike the mean value, which is the sum of a set of numbers divided by the count 
              of numbers in the set). The median value is determined by choosing the smallest 
              value such that at least half of the values in the set are no greater than the 
              chosen value. If the number of values within the set is odd, the median value 
              corresponds to a single value. If the number of values within the set is even, 
              the median value corresponds to the sum of the two middle values divided by two.</td>

              input rows then sum() returns NULL but total() returns 0.0. NULL is not normally
              a helpful result for the sum of no rows but the SQL standard requires it and most
              other SQL database engines implement sum() that way so SQLite does it in the same
              way in order to be compatible. The non-standard total() function is provided as
              a convenient way to work around this design problem in the SQL language.

              </p>
              <p>
                The result of total() is always a floating point value. The result of sum() is an
                integer value if all non-NULL inputs are integers. If any input to sum() is neither
                an integer or a NULL then sum() returns a floating point value which might be an
                approximation to the true sum.</p>
              <p>
                Sum() will throw an "integer overflow" exception if all inputs are integers or NULL
                and an integer overflow occurs at any point during the computation. Total() never
                throws an exception.</p>

      <p>
        The INSERT statement comes in two basic forms. The first form (with the "VALUES"
        keyword) creates a single new row in an existing table. If no column-list is specified
        then the number of values must be the same as the number of columns in the table.
        If a column-list is specified, then the number of values must match the number of
        specified columns. Columns of the table that do not appear in the column list are
        filled with the default value, or with NULL if not default value is specified.
      </p>
      <p>
        The second form of the INSERT statement takes it data
        from a SELECT statement. The
        number of columns in the result of the SELECT must exactly match the number of columns
        in the table if no column list is specified, or it must match the number of columns
        name in the column list. A new entry is made in the table for every row of the SELECT
        result. The SELECT may be simple or compound. If the SELECT statement has an ORDER
        BY clause, the ORDER BY is ignored.</p>
      <p>
        The optional conflict-clause allows the specification of an alternative constraint conflict resolution algorithm to use during this one command. See the section titled
        <a href="lang_conflict.html">ON CONFLICT</a> for additional information. For compatibility
        with MySQL, the parser allows the use of the single keyword <a href="lang_replace.html">
          REPLACE</a> as an alias for "INSERT OR REPLACE".

      <p>
        The REINDEX command is used to delete and recreate indices from scratch. This is
        useful when the definition of a collation sequence has changed.
      </p>
      <p>
        In the first form, all indices in all attached databases that use the named collation
        sequence are recreated. In the second form, if <i>[database-name.]table/index-name</i>
        identifies a table, then all indices associated with the table are rebuilt. If an
        index is identified, then only this specific index is deleted and recreated.
      </p>
      <p>
        If no <i>database-name</i> is specified and there exists both a table or index and
        a collation sequence of the specified name, then indices associated with the collation
        sequence only are reconstructed. This ambiguity may be dispelled by always specifying
        a <i>database-name</i> when reindexing a specific table or index.

        The REPLACE command is an alias for the "INSERT OR REPLACE" variant of the <a href="lang_insert.html">
          INSERT</a> command. This alias is provided for compatibility with MySQL. See the
        <a href="lang_insert.html">INSERT</a> command documentation for additional information.</p>

      <p>
        The SELECT statement is used to query the database. The result of a SELECT is zero
        or more rows of data where each row has a fixed number of columns. The number of
        columns in the result is specified by the expression list in between the SELECT
        and FROM keywords. Any arbitrary expression can be used as a result. If a result
        expression is <font color="#2c2cf0"><big>*</big></font> then all columns of all
        tables are substituted for that one expression. If the expression is the name of
        a table followed by <font color="#2c2cf0"><big>.*</big></font> then the result is
        all columns in that one table.</p>
      <p>
        The DISTINCT keyword causes a subset of result rows to be returned, in which each
        result row is different. NULL values are not treated as distinct from each other.
        The default behavior is that all result rows be returned, which can be made explicit
        with the keyword ALL.</p>
      <p>
        The query is executed against one or more tables specified after the FROM keyword.
        If multiple tables names are separated by commas, then the query is against the
        cross join of the various tables. The full SQL-92 join syntax can also be used to
        specify joins. A sub-query in parentheses may be substituted for any table name
        in the FROM clause. The entire FROM clause may be omitted, in which case the result
        is a single row consisting of the values of the expression list.
      </p>
      <p>
        The WHERE clause can be used to limit the number of rows over which the query operates.</p>
      <p>
        The GROUP BY clauses causes one or more rows of the result to be combined into a
        single row of output. This is especially useful when the result contains aggregate
        functions. The expressions in the GROUP BY clause do <em>not</em> have to be expressions
        that appear in the result. The HAVING clause is similar to WHERE except that HAVING
        applies after grouping has occurred. The HAVING expression may refer to values,
        even aggregate functions, that are not in the result.</p>
      <p>
        The ORDER BY clause causes the output rows to be sorted. The argument to ORDER BY
        is a list of expressions that are used as the key for the sort. The expressions
        do not have to be part of the result for a simple SELECT, but in a compound SELECT
        each sort expression must exactly match one of the result columns. Each sort expression
        may be optionally followed by a COLLATE keyword and the name of a collating function
        used for ordering text and/or keywords ASC or DESC to specify the sort order.</p>
      <p>
        The LIMIT clause places an upper bound on the number of rows returned in the result.
        A negative LIMIT indicates no upper bound. The optional OFFSET following LIMIT specifies
        how many rows to skip at the beginning of the result set. In a compound query, the
        LIMIT clause may only appear on the final SELECT statement. The limit is applied
        to the entire query not to the individual SELECT statement to which it is attached.
        Note that if the OFFSET keyword is used in the LIMIT clause, then the limit is the
        first number and the offset is the second number. If a comma is used instead of
        the OFFSET keyword, then the offset is the first number and the limit is the second
        number. This seeming contradition is intentional - it maximizes compatibility with
        legacy SQL database systems.
      </p>
      <p>
        A compound SELECT is formed from two or more simple SELECTs connected by one of
        the operators UNION, UNION ALL, INTERSECT, or EXCEPT. In a compound SELECT, all
        the constituent SELECTs must specify the same number of result columns. There may
        be only a single ORDER BY clause at the end of the compound SELECT. The UNION and
        UNION ALL operators combine the results of the SELECTs to the right and left into
        a single big table. The difference is that in UNION all result rows are distinct
        where in UNION ALL there may be duplicates. The INTERSECT operator takes the intersection
        of the results of the left and right SELECTs. EXCEPT takes the result of left SELECT
        after removing the results of the right SELECT. When three or more SELECTs are connected
        into a compound, they group from left to right.</p>

      <p>
        Beginning in version 2.0, SQLite supports transactions with rollback and atomic
        commit.</p>
      <p>
        The optional transaction name is ignored. SQLite currently does not allow nested
        transactions.</p>
      <p>
        No changes can be made to the database except within a transaction. Any command
        that changes the database (basically, any SQL command
          other than SELECT) will automatically start a transaction if one is not already in effect. Automatically started transactions
        are committed at the conclusion of the command.
      </p>
      <p>
        Transactions can be started manually using the BEGIN command. Such transactions
        usually persist until the next COMMIT or ROLLBACK command. But a transaction will
        also ROLLBACK if the database is closed or if an error occurs and the ROLLBACK conflict
        resolution algorithm is specified. See the documentation on the <a href="lang_conflict.html">
          ON CONFLICT</a> clause for additional information about the ROLLBACK conflict
        resolution algorithm.
      </p>
      <p>
        In SQLite version 3.0.8 and later, transactions can be deferred, immediate, or exclusive.
        Deferred means that no locks are acquired on the database until the database is
        first accessed. Thus with a deferred transaction, the BEGIN statement itself does
        nothing. Locks are not acquired until the first read or write operation. The first
        read operation against a database creates a SHARED lock and the first write operation
        creates a RESERVED lock. Because the acquisition of locks is deferred until they
        are needed, it is possible that another thread or process could create a separate
        transaction and write to the database after the BEGIN on the current thread has
        executed. If the transaction is immediate, then RESERVED locks are acquired on all
        databases as soon as the BEGIN command is executed, without waiting for the database
        to be used. After a BEGIN IMMEDIATE, you are guaranteed that no other thread or
        process will be able to write to the database or do a BEGIN IMMEDIATE or BEGIN EXCLUSIVE.
        Other processes can continue to read from the database, however. An exclusive transaction
        causes EXCLUSIVE locks to be acquired on all databases. After a BEGIN EXCLUSIVE,
        you are guaranteed that no other thread or process will be able to read or write
        the database until the transaction is complete.
      </p>
      <p>
        A description of the meaning of SHARED, RESERVED, and EXCLUSIVE locks is available
        <a href="lockingv3.html">separately</a>.
      </p>
      <p>
        The default behavior for SQLite version 3.0.8 is a deferred transaction. For SQLite
        version 3.0.0 through 3.0.7, deferred is the only kind of transaction available.
        For SQLite version 2.8 and earlier, all transactions are exclusive.
      </p>
      <p>
        The COMMIT command does not actually perform a commit until all pending SQL commands
        finish. Thus if two or more SELECT statements are in the middle of processing and
        a COMMIT is executed, the commit will not actually occur until all SELECT statements
        finish.
      </p>
      <p>
        An attempt to execute COMMIT might result in an SQLITE_BUSY return code. This indicates
        that another thread or process had a read lock on the database that prevented the
        database from being updated. When COMMIT fails in this way, the transaction remains
        active and the COMMIT can be retried later after the reader has had a chance to
        clear.

      <p>
        Use the TYPES keyword before a SELECT statement to provide the SQLite ADO.NET provider
        a list of return datatypes to expect from the subsequent SELECT statement.&nbsp;
      </p>
      <p>
        This is a language extension (aka <strong>hack</strong>) to SQLite specifically for the ADO.NET data
        provider.&nbsp; It is a pseudo-statement, meaning only the ADO.NET provider understands
        it.</p>
      <h3>
        Background</h3>
      <p>
        Due to SQLite's typeless nature, there are certain kinds of queries for which the
        ADO.NET provider cannot determine the proper return data type.&nbsp; Scalar and
        aggregate functions pose a particular problem because
        there is no requirement for a given scalar or aggregate function to return any particular
        datatype.&nbsp; As a matter of fact, scalar functions could theoretically return
        a different datatype for every row or column in a query and this is perfectly legal
        from SQLite's point of view.</p>
      <p>
        Since ADO.NET is designed around a typed system and we're shoe-horning SQLite into
        it, this keyword helps the provider out in cases where the return type cannot be easily determined.</p>
      <p>
        This command must be used in conjunction with a SELECT statement.&nbsp; It only
        works when both the TYPES keyword and its value(s) are passed along with a SELECT
        statement as a single semi-colon separated unit.</p>
      <h3>
        Examples</h3>
      <p>
        <strong><span style="color: #2c2cf0">TYPES</span> [bigint], [int], [smallint], [tinyint];<br />
          <span style="color: #2c2cf0">SELECT</span> 1, 2, 3, 4;</strong></p>
      <p>
        The above query would return the columns as types System.Int64, System.Int32, System.Int16
        and System.Byte respectively.</p>
      <p>
        <strong><span style="color: #2c2cf0">TYPES</span> [bigint], [int], , [tinyint];<br />
          <span style="color: #2c2cf0">SELECT</span> 1, 2, 3, 4;</strong></p>
      <p>
        In this sample, only columns 1, 2 and 4 would have explicit typing.&nbsp; Column
        3's datatype would pass though the system and be discovered normally.</p>
      <p>
        <strong><span style="color: #2c2cf0">TYPES</span> real;<br />
          <span style="color: #2c2cf0">SELECT</span> SUM(Cost) FROM [Products];</strong></p>
      <p>
        The above query explicitly tells the provider that the SUM aggregate function returns
        a System.Double.</p>
      <h3>
        Usage Notes</h3>
      <ul>
        <li>You cannot use parameters in the TYPES statement.</li>
        <li>The TYPES statement must be immediately followed by a SELECT statement.</li>
        <li>It is legal to pass multiple TYPES and SELECT statements in a multi-statement
          command.</li>
        <li>You may enclose datatypes in quotes <strong>""</strong> or brackets <strong>[]</strong>
          or those <strong>``</strong> thingies if you want.<br />
        </li>

      <p>
        The UPDATE statement is used to change the value of columns in selected rows of
        a table. Each assignment in an UPDATE specifies a column
        name to the left of the
        equals sign and an arbitrary expression to the right. The expressions may use the
        values of
          other columns. All expressions are evaluated before any assignments are
        made. A WHERE clause can be used to restrict which rows are updated.</p>
      <p>
        The optional conflict-clause allows the specification of an alternative constraint conflict resolution algorithm to use during this one command. See the section titled
        <a href="lang_conflict.html">ON CONFLICT</a> for additional information.</p>

      <p>
        The VACUUM command is an SQLite extension modeled after a similar command found
        in PostgreSQL. If VACUUM is invoked with the name of a table or index then it is
        suppose to clean up the named table or index. In version 1.0 of SQLite, the VACUUM
        command would invoke <b>gdbm_reorganize()</b> to clean up the backend database file.</p>
      <p>
        VACUUM became a no-op when the GDBM backend was removed from SQLITE in version 2.0.0.
        VACUUM was reimplemented in version 2.8.1. The index or table name argument is now
        ignored.
      </p>
      <p>
        When an object (table, index, or trigger) is dropped from the database, it leaves
        behind empty space. This makes the database file larger than it needs to be, but
        can speed up inserts. In time inserts and deletes can leave the database file structure
        fragmented, which slows down disk access to the database contents. The VACUUM command
        cleans the main database by copying its contents to a temporary database file and
        reloading the original database file from the copy. This eliminates free pages,
        aligns table data to be contiguous, and otherwise cleans up the database file structure.
        It is not possible to perform the same process on an attached database file.</p>
      <p>
        This command will fail if there is an active transaction. This command has no effect
        on an in-memory database.</p>
      <p>
        As of SQLite version 3.1, an alternative to using the VACUUM command is auto-vacuum
        mode, enabled using the <a href="pragma.html#pragma_auto_vacuum">auto_vacuum pragma</a>.</p>

      <h1 class="heading">Limitations of this ADO.NET SQLite Data Provider</h1>
      <p>As providers go, this one doesn't have many restrictions. SQLite has no 
        support for row-level or table-level locks. When a connection locks the database for writing, no other connection or process may read or write to the database until the write operation is complete.  The SQLite.NET provider attempts to retry 
        internally if a database is locked, up to the CommandTimeout property of the 
        command in question.</p>
      <p>SQLite is inherently type-less, and only understands a few basic datatypes 
        natively. They are (in .NET-speak) Int64, Double, String and Blob. The 
        SQLite.NET provider will use the database schema information it can glean to 
        enforce type-ness, but it is an inexact science.</p>
      <p>
        Hierarchical DataReaders are not supported. In the 
        case of transactions, any SQLiteCommand created on a connection will (when 
        executed) automatically join a transaction in progress, regardless of whether 
        that transaction was created before or after the command.</p>
      <p>A SQLiteCommand object <b>can</b> be re-assigned a new SQLiteConnection object 
        as long as no DataReaders are active on the command.</p>
      <p>Opening a transaction is considered a write operation, so only use them when 
        you want to write to the database! If you hold open a transaction, all readers on other
        connections
        will be blocked until the transaction is closed!</p>
      <p></p>
      <h4 class="subHeading">Thread Safety</h4>
      <p>Multi-threading in SQLite must be done carefully. Here are the restrictions:</p>
      <ul>
        <li>
          <b>You May</b>
        Clone() a SQLiteConnection object in one thread and pass the cloned object to 
        another thread. Once passed, the other thread becomes the new owner of the 
        cloned connection, and the original thread must not keep a reference to the 
        clone or call any methods on the clone.
        <LI>
          <STRONG>You May</STRONG>
        create multiple threads, and those threads can create their own 
        SQLiteConnection and subsequent objects for accessing a database.&nbsp; 
        Multiple connections on multiple threads to the same database file are 
        perfectly&nbsp;acceptable&nbsp;and will behave predictably.&nbsp;
        <li>
          <b>You May NOT</b>
        call methods or properties or otherwise reference any SQLite provider classes 
        that belong to another thread.
        <li>
          <b>You May NOT</b> pass a SQLiteCommand, SQLiteDataReader, SQLiteDataAdapter or 
          any other SQLite provider class except a cloned SQLiteConnection to another 
          thread.</li>
      </ul>
      <p>Understand again that SQLite has no fine-grained locking mechanisms. It is 
        therefore your own responsibility in a multi-threaded environment to handle 
        potential timeouts that may occur if a long-running query in one thread 
        prevents a query in another thread from executing. These timeouts will only 
        occur if one thread is attempting to read while another thread is attempting to 
        write. Whichever thread got its lock first will be the one to execute, and the 
        other thread will block until the CommandTimeout value elapses or the other 
        thread finishes.</p>

      <h1 class="heading">Tips on Optimizing Your Queries</h1>
      <p>The next few paragraphs will attempt to give you a few rudimentary rules for 
        speeding up your queries in general, and especially how SQLite is adversely 
        affected by the kinds of SQL behaviors you may have taken for granted in other 
        providers. It is by no means a complete optimization guide. For even more 
        details on optimizing your queries, visit <a href="http://www.sqlite.org">sqlite.org</a>.</p>
      <h4 class="subHeading">The Importance of Transactions</h4>
      <p>If you are inserting data in SQLite without first starting a transaction: <b>DO 
          NOT PASS GO! Call BeginTransaction() right now, and finish with Commit()!</b> 
        If you think I'm kidding, think again. SQLite's A.C.I.D. design means that 
        every single time you insert any data outside a transaction, an implicit 
        transaction is constructed, the insert made, and the transaction destructed. <b>EVERY 
          TIME.</b> If you're wondering why in the world your inserts are taking 100x 
        longer than you think they should, look no further.</p>
      <h4 class="subHeading">Prepared Statements</h4>
      <p>Lets have a quick look at the following code and evaluate its performance:</p>
      <div class="syntax">
        <pre>
      using (SQLiteCommand mycommand = new SQLiteCommand(myconnection))
      {
        int n;
        
        for (n = 0; n < 100000; n ++)
        {
          mycommand.CommandText = String.Format("INSERT INTO [MyTable] ([MyId]) VALUES({0})", n + 1);
          mycommand.ExecuteNonQuery();
        }
      }</pre>
      </div>
      <p>This code seems pretty tight, but if you think it performs well, you're dead 
        wrong. Here's what's wrong with it:</p>
      <ul>
        <li>
          I didn't start a transaction first! This insert is dog slow!</li>
        <li>
          The CLR is calling "new" implicitly 100,000 times because I am formatting a 
          string in the loop for every insert</li>
        <li>
          Since SQLite precompiles SQL statements, the engine is constructing and 
          deconstructing 100,000 SQL statements and allocating/deallocating their memory</li>
        <li>
          All this construction and destruction is involving about 300,000 more native to 
          managed interop calls than an optimized insert</li>
      </ul>
      <p>So lets rewrite that code slightly:</p>
      <div class="syntax">
        <pre>
      using (SQLiteTransaction mytransaction = myconnection.BeginTransaction())
      {
        using (SQLiteCommand mycommand = new SQLiteCommand(myconnection))
        {
          SQLiteParameter myparam = new SQLiteParameter();
          int n;
        
          mycommand.CommandText = "INSERT INTO [MyTable] ([MyId]) VALUES(?)";
          mycommand.Parameters.Add(myparam);
          
          for (n = 0; n < 100000; n ++)
          {
            myparam.Value = n + 1;
            mycommand.ExecuteNonQuery();
          }
        }
        mytransaction.Commit();
      } </pre>
      </div>
      <p>Now this is a blazing fast insert for <b><i>any</i></b> database engine, not 
        just SQLite. The SQL statement is prepared one time -- on the first call to 
        ExecuteNonQuery(). Once prepared, it never needs re-evaluating. Furthermore, 
        we're allocating no memory in the loop and doing a very minimal number of 
        interop transitions. Surround the entire thing with a transaction, and the 
        performance of this insert is so far and away faster than the original that it 
        merits a hands-on-the-hips pirate-like laugh.</p>
      <p>Every database engine worth its salt utilizes prepared statements. If you're 
        not coding for this, you're not writing optimized SQL, and that's the bottom 
        line.
      </p>

        SQL As Understood By SQLite</h1>
      <h4>
        PRAGMA</h4>
      <p>
        The <a href="#syntax">PRAGMA command</a> is a special command used to modify the
        operation of the SQLite library or to query the library for internal (non-table)
        data. The PRAGMA command is issued using the same interface as other SQLite commands
        (e.g. SELECT, INSERT) but is different in the following important respects:
      </p>
      <ul>
        <li>Specific pragma statements may be removed and others added in future releases
          of SQLite. Use with caution! </li>
        <li>No error messages are generated if an unknown pragma is issued. Unknown pragmas
          are simply ignored. This means if there is a typo in a pragma statement the library
          does not inform the user of the fact. </li>
        <li>Some pragmas take effect during the SQL compilation stage, not the execution stage.
          This means if using the C-language sqlite3_compile(), sqlite3_step(), sqlite3_finalize()
          API (or similar in a wrapper interface), the pragma may be applied to the library
          during the sqlite3_compile() call. </li>
        <li>The pragma command is unlikely to be compatible with any other SQL engine. </li>
      </ul>
      <p>
        The available pragmas fall into four basic categories:</p>
      <ul>
        <li>Pragmas used to <a href="#schema">query the schema</a> of the current database.
        </li>
        <li>Pragmas used to <a href="#modify">modify the operation</a> of the SQLite library
          in some manner, or to query for the current mode of operation. </li>
        <li>Pragmas used to <a href="#version">query or modify the databases two version values</a>,
          the schema-version and the user-version. </li>
        <li>Pragmas used to <a href="#debug">debug the library</a> and verify that database
          files are not corrupted. </li>
      </ul>

        The pragmas that take an integer <b><i>value</i></b> also accept symbolic names.
        The strings "<b>on</b>", "<b>true</b>", and "<b>yes</b>" are equivalent to <b>1</b>.
        The strings "<b>off</b>", "<b>false</b>", and "<b>no</b>" are equivalent to <b>0</b>.
        These strings are case- insensitive, and do not require quotes. An unrecognized
        string will be treated as <b>1</b>, and will not generate an error. When the <i>value</i>
        is returned it is as an integer.</p>

        Pragmas to modify library operation</h1>
      <ul>
        <a name="pragma_auto_vacuum"></a>
        <li>
          <p>
            <b>PRAGMA auto_vacuum;
              <br />
              PRAGMA auto_vacuum = </b><i>0 | 1</i><b>;</b></p>
          <p>
            Query or set the auto-vacuum flag in the database.</p>
          <p>
            Normally, when a transaction that deletes data from a database is committed, the
            database file remains the same size. Unused database file pages are marked as such
            and reused later on, when data is inserted into the database. In this mode the <a
              href="lang_vacuum.html">VACUUM</a> command is used to reclaim unused space.</p>
          <p>
            When the auto-vacuum flag is set, the database file shrinks when a transaction that
            deletes data is committed (The VACUUM command is not useful in a database with the
            auto-vacuum flag set). To support this functionality the database stores extra information
            internally, resulting in slightly larger database files than would otherwise be
            possible.</p>
          <p>
            It is only possible to modify the value of the auto-vacuum flag before any tables
            have been created in the database. No error message is returned if an attempt to
            modify the auto-vacuum flag is made after one or more tables have been created.
          </p>
          <a name="pragma_cache_size"></a></li>
        <li>
          <p>
            <b>PRAGMA cache_size;
              <br />
              PRAGMA cache_size = </b><i>Number-of-pages</i><b>;</b></p>
          <p>
            Query or change the maximum number of database disk pages that SQLite will hold
            in memory at once. Each page uses about 1.5K of memory. The default cache size is
            2000. If you are doing UPDATEs or DELETEs that change many rows of a database and
            you do not mind if SQLite uses more memory, you can increase the cache size for
            a possible speed improvement.</p>
          <p>
            When you change the cache size using the cache_size pragma, the change only endures
            for the current session. The cache size reverts to the default value when the database
            is closed and reopened. Use the <a href="#pragma_default_cache_size"><b>default_cache_size</b></a>
            pragma to check the cache size permanently.</p>
          <a name="pragma_case_sensitive_like"></a></li>
        <li>
          <p>
            <b>PRAGMA case_sensitive_like;
              <br />
              PRAGMA case_sensitive_like = </b><i>0 | 1</i><b>;</b></p>
          <p>
            The default behavior of the LIKE operator is to ignore case for latin1 characters.
            Hence, by default <b>'a' LIKE 'A'</b> is true. The case_sensitive_like pragma can
            be turned on to change this behavior. When case_sensitive_like is enabled, <b>'a'
              LIKE 'A'</b> is false but <b>'a' LIKE 'a'</b> is still true.</p>
          <a name="pragma_count_changes"></a></li>
        <li>
          <p>
            <b>PRAGMA count_changes;
              <br />
              PRAGMA count_changes = </b><i>0 | 1</i><b>;</b></p>
          <p>
            Query or change the count-changes flag. Normally, when the count-changes flag is
            not set, INSERT, UPDATE and DELETE statements return no data. When count-changes
            is set, each of these commands returns a single row of data consisting of one integer
            value - the number of rows inserted, modified or deleted by the command. The returned
            change count does not include any insertions, modifications or deletions performed
            by triggers.</p>
          <a name="pragma_default_cache_size"></a></li>
        <li>
          <p>
            <b>PRAGMA default_cache_size;
              <br />
              PRAGMA default_cache_size = </b><i>Number-of-pages</i><b>;</b></p>
          <p>
            Query or change the maximum number of database disk pages that SQLite will hold
            in memory at once. Each page uses 1K on disk and about 1.5K in memory. This pragma
            works like the <a href="#pragma_cache_size"><b>cache_size</b></a> pragma with the
            additional feature that it changes the cache size persistently. With this pragma,
            you can set the cache size once and that setting is retained and reused every time
            you reopen the database.</p>
          <a name="pragma_default_synchronous"></a></li>
        <li>
          <p>
            <b>PRAGMA default_synchronous;</b></p>
          <p>
            This pragma was available in version 2.8 but was removed in version 3.0. It is a
            dangerous pragma whose use is discouraged. To help dissuide users of version 2.8
            from employing this pragma, the documentation will not tell you what it does.</p>
          <a name="pragma_empty_result_callbacks"></a></li>
        <li>
          <p>
            <b>PRAGMA empty_result_callbacks;
              <br />
              PRAGMA empty_result_callbacks = </b><i>0 | 1</i><b>;</b></p>
          <p>
            Query or change the empty-result-callbacks flag.</p>
          <p>
            The empty-result-callbacks flag affects the sqlite3_exec API only. Normally, when
            the empty-result-callbacks flag is cleared, the callback function supplied to the
            sqlite3_exec() call is not invoked for commands that return zero rows of data. When
            empty-result-callbacks is set in this situation, the callback function is invoked
            exactly once, with the third parameter set to 0 (NULL). This is to enable programs
            that use the sqlite3_exec() API to retrieve column-names even when a query returns
            no data.
          </p>
          <a name="pragma_encoding"></a></li>
        <li>
          <p>
            <b>PRAGMA encoding;
              <br />
              PRAGMA encoding = "UTF-8";
              <br />
              PRAGMA encoding = "UTF-16";
              <br />
              PRAGMA encoding = "UTF-16le";
              <br />
              PRAGMA encoding = "UTF-16be";</b></p>
          <p>
            In first form, if the main database has already been created, then this pragma returns
            the text encoding used by the main database, one of "UTF-8", "UTF-16le" (little-endian
            UTF-16 encoding) or "UTF-16be" (big-endian UTF-16 encoding). If the main database
            has not already been created, then the value returned is the text encoding that
            will be used to create the main database, if it is created by this session.</p>
          <p>
            The second and subsequent forms of this pragma are only useful if the main database
            has not already been created. In this case the pragma sets the encoding that the
            main database will be created with if it is created by this session. The string
            "UTF-16" is interpreted as "UTF-16 encoding using native machine byte-ordering".
            If the second and subsequent forms are used after the database file has already
            been created, they have no effect and are silently ignored.</p>
          <p>
            Once an encoding has been set for a database, it cannot be changed.</p>
          <p>
            Databases created by the ATTACH command always use the same encoding as the main
            database.</p>
          <a name="pragma_full_column_names"></a></li>
        <li>
          <p>

              PRAGMA full_column_names = </b><i>0 | 1</i><b>;</b></p>
          <p>
            Query or change the full-column-names flag. This flag affects the way SQLite names
            columns of data returned by SELECT statements when the expression for the column
            is a table-column name or the wildcard "*". Normally, such result columns are named
            &lt;table-name/alias&gt;&lt;column-name&gt; if the SELECT statement joins two or
            more tables together, or simply &lt;column-name&gt; if the SELECT statement queries
            a single table. When the full-column-names flag is set, such columns are always
            named &lt;table-name/alias&gt; &lt;column-name&gt; regardless of whether or not
            a join is performed.
          </p>
          <p>
            If both the short-column-names and full-column-names are set, then the behaviour
            associated with the full-column-names flag is exhibited.

          <p>
            Query or change the fullfsync flag. This flag affects determines whether or not
            the F_FULLFSYNC syncing method is used on systems that support it. The default value
            is off. As of this writing (2006-02-10) only Mac OS X supports F_FULLFSYNC.

              PRAGMA legacy_file_format = <i>ON | OFF</i></b></p>
          <p>
            This pragma sets or queries the value of the legacy_file_format flag. When this
            flag is on, new SQLite databases are created in a file format that is readable and
            writable by all versions of SQLite going back to 3.0.0. When the flag is off, new
            databases are created using the latest file format which might to be readable or
            writable by older versions of SQLite.</p>
          <p>
            This flag only effects newly created databases. It has no effect on databases that
            already exists.</p>

            Query or set the page-size of the database. The page-size may only be set if the
            database has not yet been created. The page size must be a power of two greater
            than or equal to 512 and less than or equal to 8192. The upper limit may be modified
            by setting the value of macro SQLITE_MAX_PAGE_SIZE during compilation. The maximum

          <p>
            Query, set, or clear READ UNCOMMITTED isolation. The default isolation level for
            SQLite is SERIALIZABLE. Any process or thread can select READ UNCOMMITTED isolation,
            but SERIALIZABLE will still be used except between connections that share a common
            page and schema cache. Cache sharing is enabled using the <a href="capi3ref.html#sqlite3_enable_shared_cache">
              sqlite3_enable_shared_cache()</a> API and is only available between connections

          <p>
            Query or change the setting of the "synchronous" flag. The first (query) form will
            return the setting as an integer. When synchronous is FULL (2), the SQLite database
            engine will pause at critical moments to make sure that data has actually been written
            to the disk surface before continuing. This ensures that if the operating system
            crashes or if there is a power failure, the database will be uncorrupted after rebooting.
            FULL synchronous is very safe, but it is also slow. When synchronous is NORMAL,
            the SQLite database engine will still pause at the most critical moments, but less
            often than in FULL mode. There is a very small (though non-zero) chance that a power
            failure at just the wrong time could corrupt the database in NORMAL mode. But in
            practice, you are more likely to suffer a catastrophic disk failure or some other
            unrecoverable hardware fault. With synchronous OFF (0), SQLite continues without
            pausing as soon as it has handed data off to the operating system. If the application
            running SQLite crashes, the data will be safe, but the database might become corrupted
            if the operating system crashes or the computer loses power before that data has
            been written to the disk surface. On the other hand, some operations are as much
            as 50 or more times faster with synchronous OFF.
          </p>
          <p>
            In SQLite version 2, the default value is NORMAL. For version 3, the default was
            changed to FULL.

            Query or change the setting of the "<b>temp_store</b>" parameter. When temp_store
            is DEFAULT (0), the compile-time C preprocessor macro TEMP_STORE is used to determine
            where temporary tables and indices are stored. When temp_store is MEMORY (2) temporary
            tables and indices are kept in memory. When temp_store is FILE (1) temporary tables
            and indices are stored in a file. The <a href="#pragma_temp_store_directory">temp_store_directory</a>
            pragma can be used to specify the directory containing this file. <b>FILE</b> is
            specified. When the temp_store setting is changed, all existing temporary tables,
            indices, triggers, and views are immediately deleted.</p>
          <p>
            It is possible for the library compile-time C preprocessor symbol TEMP_STORE to
            override this pragma setting. The following table summarizes the interaction of
            the TEMP_STORE preprocessor macro and the temp_store pragma:</p>

          <p>
            Query or change the setting of the "temp_store_directory" - the directory where
            files used for storing temporary tables and indices are kept. This setting lasts
            for the duration of the current connection only and resets to its default value
            for each new connection opened.
          </p>
          <p>
            When the temp_store_directory setting is changed, all existing temporary tables,
            indices, triggers, and viewers are immediately deleted. In practice, temp_store_directory
            should be set immediately after the database is opened.
          </p>
          <p>
            The value <i>directory-name</i> should be enclosed in single quotes. To revert the
            directory to the default, set the <i>directory-name</i> to an empty string, e.g.,
            <i>PRAGMA temp_store_directory = ''</i>. An error is raised if <i>directory-name</i>
            is not found or is not writable.
          </p>
          <p>
            The default directory for temporary files depends on the OS. For Unix/Linux/OSX,
            the default is the is the first writable directory found in the list of: <b>/var/tmp,
              /usr/tmp, /tmp,</b> and <b><i>current-directory</i></b>. For Windows NT, the default
            directory is determined by Windows, generally <b>C:\Documents and Settings\<i>user-name</i>\Local
              Settings\Temp\</b>. Temporary files created by SQLite are unlinked immediately
            after opening, so that the operating system can automatically delete the files when
            the SQLite process exits. Thus, temporary files are not normally visible through
            <i>ls</i> or <i>dir</i> commands.</p>

          </p>
          <p>
            The pragmas schema_version and user_version are used to set or get the value of
            the schema-version and user-version, respectively. Both the schema-version and the
            user-version are 32-bit signed integers stored in the database header.</p>
          <p>
            The schema-version is usually only manipulated internally by SQLite. It is incremented
            by SQLite whenever the database schema is modified (by creating or dropping a table
            or index). The schema version is used by SQLite each time a query is executed to
            ensure that the internal cache of the schema used when compiling the SQL query matches
            the schema of the database against which the compiled query is actually executed.
            Subverting this mechanism by using "PRAGMA schema_version" to modify the schema-version
            is potentially dangerous and may lead to program crashes or database corruption.
            Use with caution!</p>
          <p>
            The user-version is not used internally by SQLite. It may be used by applications
            for any purpose.</p>

            The command does an integrity check of the entire database. It looks for out-of-order
            records, missing pages, malformed records, and corrupt indices. If any problems
            are found, then a single string is returned which is a description of all problems.

            Turn listings of virtual machine programs on and off. With listing is on, the entire

        SQL As Understood By SQLite</h1>
      <p>
        The SQLite library understands most of the standard SQL language. But it does omit
        some features while at the same time adding a few features of its own. This document
        attempts to describe precisely what parts of the SQL language SQLite does and does
        not support. A list of keywords is also provided. In all of the syntax diagrams
        that follow, literal text is shown in bold blue. Non-terminal symbols are shown
        in italic red. Operators that are part of the syntactic markup itself are shown
        in black roman. This document is just an overview of the SQL syntax implemented
        by SQLite.
      </p>

    <p><b>1.0.77.0 - November 28, 2011</b></p>
    <ul>
      <li>Updated to SQLite 3.7.9 <a href="http://www.sqlite.org/src/info/a499ae3835">[a499ae3835]</a>.</li>
      <li>More enhancements to the build and test automation.</li>
      <li>Plug native memory leak when closing a database connection containing a statement that cannot be finalized for some reason.</li>
      <li>The SQLite3 class should always attempt to dispose the contained SQLiteConnectionHandle, even when called via the finalizer.</li>
      <li>When compiled with DEBUG defined, emit diagnostic information related to resource cleanup to any TraceListener objects that may be registered.</li>
      <li>Stop characterizing all log messages as errors. From now on, if the errorCode is zero, the message will not be considered an error.</li>
      <li>Never attempt to configure the native logging interface if the SQLite core library has already been initialized for the process. Fix for <a href="http://system.data.sqlite.org/index.html/info/2ce0870fad">[2ce0870fad]</a>.</li>
      <li>Allow the SQLiteLog class to be used for logging messages without having an open connection.</li>
      <li>Support building the core System.Data.SQLite assemblies using the .NET Framework 4.0 Client Profile. Fix for <a href="http://system.data.sqlite.org/index.html/info/566f1ad1e4">[566f1ad1e4]</a>.</li>
      <li>When generating the schema based on the contents of a SQLiteDataReader, skip flagging columns as unique if the data reader is holding the result of some kind of multi-table construct (e.g. a cross join) because we must allow duplicate values in that case. Fix for <a href="http://system.data.sqlite.org/index.html/info/7e3fa93744">[7e3fa93744]</a>.</li>
      <li>When returning schema information that may be used by the .NET Framework to construct dynamic SQL, use a fake schema name (instead of null) so that the table names will be properly qualified with the catalog name (i.e. the attached database name). Partial fix for <a href="http://system.data.sqlite.org/index.html/info/343d392b51">[343d392b51]</a>.</li>
      <li>Add SQLiteSourceId property to the SQLiteConnection class to return the SQLite source identifier.</li>
      <li>Add MemoryUsed and MemoryHighwater properties to the SQLiteConnection class to help determine the memory usage of SQLite.</li>
      <li>Add DateTimeKind connection string property to control the DateTimeKind of parsed DateTime values. Partial fix for <a href="http://system.data.sqlite.org/index.html/info/343d392b51">[343d392b51]</a>.</li>
      <li>Improve the robustness of the SQLiteLog class when it will be initialized and unloaded multiple times.</li>
      <li>Fix the name of the interop assembly for Windows CE. Add unit tests to prevent this type of issue from happening again. Fix for <a href="http://system.data.sqlite.org/index.html/info/737ca4ff74">[737ca4ff74]</a>.</li>
      <li>Formally support the SQL type name BOOLEAN in addition to BOOL. Fix for <a href="http://system.data.sqlite.org/index.html/info/544dba0a2f">[544dba0a2f]</a>.</li>
      <li>Make sure the SQLiteConvert.TypeNameToDbType method is thread-safe. Fix for <a href="http://system.data.sqlite.org/index.html/info/84718e79fa">[84718e79fa]</a>.</li>
    </ul>
    <p><b>1.0.76.0 - October 4, 2011</b></p>
    <ul>
      <li>Prevent the domain unload event handler in SQLiteLog from being registered multiple times. Fix for <a href="http://system.data.sqlite.org/index.html/info/0d5b1ef362">[0d5b1ef362]</a>.</li>
      <li>Stop allowing non-default application domains to initialize the SQLiteLog class. Fix for <a href="http://system.data.sqlite.org/index.html/info/ac47dd230a">[ac47dd230a]</a>.</li>
    </ul>
    <p><b>1.0.75.0 - October 3, 2011</b></p>

      <li>More enhancements to the build system.</li>
      <li>Add official <a href="http://www.nuget.org/">NuGet</a> packages for x86 and x64.</li>
      <li>Add Changes and LastInsertRowId properties to the connection class.</li>
      <li>Support more formats when converting data from/to the DateTime type.</li>
      <li>Make all the assembly versioning attributes consistent.</li>
      <li>Add unit testing infrastructure using <a href="http://eagle.to/">Eagle</a>.</li>
      <li>Integrate all legacy unit tests, including the &quot;testlinq&quot; project, into the new test suite.</li>
      <li>Add projects to build the interop assembly statically linked to the Visual C++ runtime. Fix for <a href="http://system.data.sqlite.org/index.html/info/53f0c5cbf6">[53f0c5cbf6]</a>.</li>
      <li>Add SQLITE_ENABLE_STAT2 compile-time option to the interop assembly.  Fix for <a href="http://system.data.sqlite.org/index.html/info/74807fbf27">[74807fbf27]</a>.</li>
      <li>Fix mutex issues exposed when running the test suite with the debug version of SQLite.</li>
      <li>Fix transaction enlistment when repeated attempts are made to enlist in the same transaction. Fix for <a href="http://system.data.sqlite.org/index.html/info/ccfa69fc32">[ccfa69fc32]</a>.</li>
      <li>Support the SQLITE_FCNTL_WIN32_AV_RETRY file control to mitigate the impact of file sharing violations caused by external processes.</li>
      <li>Refactor the logging interface to be thread-safe and self-initializing.</li>
      <li>Shutdown the SQLite native interface when the AppDomain is being unloaded. Fix for <a href="http://system.data.sqlite.org/index.html/info/b4a7ddc83f">[b4a7ddc83f]</a>.</li>
      <li>Support Skip operation for LINQ using OFFSET. Fix for <a href="http://system.data.sqlite.org/index.html/info/8b7d179c3c">[8b7d179c3c]</a>.</li>
      <li>Support EndsWith operation for LINQ using SUBSTR. Fix for <a href="http://system.data.sqlite.org/index.html/info/59edc1018b">[59edc1018b]</a>.</li>

        during the disposal of the transaction.&nbsp; If autocommit is enabled, then the
        database has already rolled back the transaction and we don&#39;t need to do it
        during dispose, and can quietly ignore the step without throwing an error.</li>
      <li>Eliminated the mergebin step altogether.&nbsp; It was developed primarily to
        merge the Compact Framework binaries together, but since we&#39;re not doing that
        anymore, its use is limited.&nbsp; Its non-standard method of merging a binary
        on the desktop framework is redundant as well.&nbsp; The desktop binary now
        hard-links to MSCOREE, but as of Windows XP, this was redundant as well since XP

        a couple different EF issues that were either giving inconsistent results or
        crashing the engine.</li>

        <a href="http://sqlite.phxsoftware.com/forums/p/1377/5921.aspx#5921">Microsoft's EF Query Samples</a> application --
        the exception being the <i>datetimeoffset </i>and<i> time</i> constants tests, and tests
        that use the <i>APPLY </i>keyword which are unsupported for now.</li>
      <li>Revamped the Compact Framework mixed-mode assembly.&nbsp; Tired of playing cat
        and mouse with the Compact Framework&#39;s support for mixed-mode assemblies.&nbsp;
        The CF build now requires that you distribute both the System.Data.SQLite
        library and the paired SQLite.Interop.XXX library.&nbsp;&nbsp; The XXX denotes
        the build number of the library.</li>
      <li>Implemented a workaround for Vista&#39;s overzealous caching by turning off
        FILE_FLAG_RANDOM_ACCESS for OS versions above XP.&nbsp; This is implemented
        as a custom (default override) VFS in the interop.c file, so no changes are made
        to the SQLite source code.</li>
      <li>Fixed some registry issues in the designer install.exe, which prevented some
        design-time stuff from working on the Compact Framework when .NET 3.5 was
        installed.</li>

        57!&nbsp; Several LINQ issues have been resolved with this engine release
        relating to deeply-nested subqueries that the EF SqlGen creates.</li>

        which fixes an Entity Framework bug I was seeing.&nbsp; I currently have 3 other
        tickets out on the engine, which are not yet resolved and relate to EF.</li>
      <li>Fixed decimal types to store and fetch using InvariantCulture.&nbsp; If you&#39;re
        using decimal datatypes in your database and were affected by the 56 release,
        please issue an UPDATE &lt;table&gt; SET &lt;column&gt; = REPLACE(&lt;column&gt;, &#39;,&#39;, &#39;.&#39;);&nbsp;
        to fix the decimal separators.&nbsp; Apologies for not testing that more
        thoroughly before releasing 56.</li>
      <li>Too many LINQ fixes to list.&nbsp; Fixed views so they generate,
        fixed the LIMIT clause, implemented additional functionality and removed unnecessary code.</li>
      <li>Fixed foreign key names in the designer so viewing the SQL script on a new
        unsaved table after renaming it in the properties toolwindow will reflect in the
        script properly.</li>
      <li>Fixed the Update and Commit events on SQLiteConnection so they don&#39;t require
        the connection to be opened first.</li>
      <li>Fixed userdef aggregate functions so they play nice with each other when
        appearing multiple times in the same statement.</li>
      <li>Fixed the editing and saving of default values in the table designer.</li>
      <li>Fixed ForeignKeys schema to support multi-column foreign keys.&nbsp; Also
        hacked support for them in the table designer, provided two foreign keys in the
        designer have the same name and reference the same foreign table and different
        columns.&nbsp; Will implement first-class support for this in the next release.</li>

    <p><b>1.0.56.0 - August 11, 2008</b></p>

        save the table first before being able to create indexes and foreign keys.</li>
      <li>Tweaks to decimal type handling.&nbsp; The &#39;decimal&#39; type can&#39;t be represented
        by Int64 or Double (without loss of precision) in SQLite, so we have to fudge it
        by treating it like a string and converting it back and forth in the provider.&nbsp;
        Unfortunately backing it to the db as a string causes sorting problems.&nbsp;

    <ul>
      <li>Code merge with SQLite 3.6.1</li>
      <li>Added support for the user-contributed extension-functions at
        <a href="http://www.sqlite.org/contrib">http://www.sqlite.org/contrib</a>.&nbsp;
        Feel free to override any of them with your own implementation.&nbsp; The new
        functions are: <i>acos, asin, atan, atn2, atan2, acosh, asinh, atanh,
        difference, degrees, radians, cos, sin, tan, cot, cosh, sinh, tanh, coth, exp,
        log, log10, power, sign, sqrt, square, ceil, floor, pi, replicate, charindex,
        leftstr, rightstr, reverse, proper, padl, padr, padc, strfilter,</i> and
        aggregates <i>stdev, variance, mode, median, lower_quartile, upper_quartile.</i></li>
      <li>Moved the last_rows_affected() function to the C extension library.</li>
      <li>Added a new class, SQLiteFunctionEx which extends SQLiteFunction and adds the
        ability for a user-defined function to get the collating sequence during the
        Invoke/Step methods.&nbsp; User-defined functions can use the collating sequence
        as a helper to compare values.</li>
      <li>When registering user-defined collation sequences and functions, the provider
        will now register both a UTF8 and a UTF16 version instead of just UTF8.</li>
      <li>Revamped connection pooling and added static ClearPool() and ClearAllPools()
        functions to SQLiteConnection.&nbsp; Behavior of the pool and its clearing
        mechanics match SqlClient.</li>
      <li>Fixed connections going to the pool so that any unfinalized lingering commands
        from un-collected datareaders are automatically reset and any lurking
        transactions made on the connection are rolled back.</li>
      <li>Transaction isolation levels are now partially supported.&nbsp; Serializable
        is the default, which obtains read/write locks immediately -- this is compatible
        with previous releases of the provider.&nbsp; Unspecified will default to
        whatever the default isolation mode is set to, and ReadCommitted will cause a
        deferred lock to be obtained.&nbsp; No other values are legal.</li>
      <li>Revamped the test.exe program.&nbsp; It&#39;s now an interactive GUI application.&nbsp;
        Easier for me to add tests now.</li>
      <li>Tweaks to the VS designer package and installer.</li>
      <li>More adjustments to the internal SQLite3.Prepare() method to account for both
        kinds of lock errors when retrying.</li>
      <li>Stripped a lot of unnecessary interop() calls and replaced with base sqlite calls.&nbsp;
        Revamped most of UnsafeNativeMethods to make it easier to port the code.</li>
      <li>Rerigged internal callbacks for userdef functions and other native to managed
        callbacks.&nbsp; More portable this way.</li>
      <li>Source can now can be compiled with the SQLITE_STANDARD preprocessor symbol to
        force the wrapper to use the stock sqlite3 library.&nbsp; Some functionality is
        missing, but its minimal.&nbsp; None of the precompiled binaries are compiled
        using this setting, but its useful for testing portability.</li>
      <li>Added &quot;boolean&quot; and a couple other missing datatypes to the &quot;DataTypes&quot; schema
        xml file.&nbsp; Used by the VS designer when displaying tables and querying.</li>
      <li>Added a new connection string option &quot;Read Only&quot;.&nbsp; When set to True, the
        database will be opened in read-only mode.</li>
      <li>Added a new connection string option &quot;Max Pool Size&quot; to set the maximum size
        of the connection pool for a given db file connection.</li>
      <li>Added a new connection string option &quot;Default IsolationLevel&quot; to set the
        default isolation level of transactions.&nbsp; Possible values are Serializable and
        ReadCommitted.</li>
      <li>Added a new connection string option &quot;URI&quot; as an optional parameter for
        compatibility with other ports of the provider.</li>
    </ul>
    <p><b>1.0.54.0 - July 25, 2008</b></p>

      <li>Fixed a crash in the table designer when creating a new table and tabbing past
        the &quot;Allow Nulls&quot; cell in the grid while creating a new column.</li>
      <li>Fixed a mostly-benign bug in SQLiteDataReader&#39;s GetEnumerator, which failed to
        pass along a flag to the underyling DbEnumerator it creates.&nbsp; This one&#39;s
        been around since day 1 and nobody&#39;s noticed it in all these years.</li>
      <li>Added a new connection string parameter &quot;Journal Mode&quot; that allows you to set
        the SQLite journal mode to Delete, Persist or Off.</li>
    </ul>
    <p><b>1.0.53.0 - July 24, 2008</b></p>

      <li>Added a new schema to SQLiteConnection.GetSchema() called <i>Triggers</i>.&nbsp;
        Used to retrieve the trigger(s) associated with a database and/or table/view.</li>
      <li>Extensive updates to table/view editing capabilities inside Visual Studio&#39;s
        Server Explorer.&nbsp; The program now parses and lets you edit CHECK constraints and
        triggers on a table, as well as define triggers on views.&nbsp; Experimental
        still, so e-mail me if you have issues.</li>
      <li>Minor bugfix to the ViewColumns schema to return the proper base column name
        for a view that aliases a column.</li>
      <li>Fixed the insert/update/delete DML support in the Linq module.</li>
      <li>Changed the behavior of SQLiteCommand to allow a transaction to be set even if
        the command hasn&#39;t been associated with a connection yet.</li>

        native library.</li>
      <li>Fixed SQLiteDataReader to check for an invalid connection before operating on
        an open cursor.</li>
      <li>Implemented the Cancel() function of SQLiteCommand to cancel an active reader.</li>
      <li>Added beta table and view designers to the Visual Studio Server Explorer.&nbsp; You can now
        edit/create tables and views, manage indexes and foreign keys from Visual Studio.&nbsp;
        This feature is still undergoing testing so use at your own risk!</li>
      <li>Fixed the Server Explorer so VS2005 users can once again right-click tables
        and views and open the table data.</li>
      <li>Added some new interop code to assist in returning more metadata not normally
        available through the SQLite API.&nbsp; Specifically, index column sort modes
        and collating sequences.&nbsp; Also added code to detect (but not parse) CHECK
        constraints, so the table designer can pop up a warning when editing a table
        with these constraints.&nbsp; Since I can&#39;t currently parse them.</li>
      <li>Lots of LINQ SQL generation improvements and fixes.</li>
      <li>Made some progress cleaning up and fixing up the schema definitions and
        manifests for EdmGen.</li>
      <li>Added a built-in SQLiteFunction called last_rows_affected() which can be
        called from SQL to get the number of rows affected by the last update/insert
        operation on the connection.&nbsp; This is roughly equivalent to Sql Server&#39;s

        System.Data.SQLite.Linq.&nbsp; Some things work, some don&#39;t.&nbsp; I haven&#39;t
        finished rigging everything up yet.&nbsp; The core library remains stable.&nbsp;
        All LINQ-specific code is completely separate from the core.</li>
      <li>&nbsp;Added some columns to several existing schemas to support some of the
        EDM framework stuff.</li>
      <li>Minor tweaks to the factory to better support dynamic loading of the Linq
        extension library for SQLite.</li>
      <li>SQLite&#39;s busy handler was interfering with the provider&#39;s busy handling
        mechanism, so its been disabled.</li>
    </ul>
    <p><b>1.0.50.0 - June 27, 2008</b></p>
    <ul>
      <li>Fixed some lingering dispose issues and race conditions when some objects were finalized.</li>
      <li>Fixed the SQLiteConvert.Split() routine to be a little smarter when splitting
        strings, which solves the quoted data source filename problem.</li>
      <li>Enhanced the mergebin utility to work around the strong name validation bug on
        the Compact Framework.&nbsp; The old workaround kludged the DLL and caused WM6.1
        to fail to load it.&nbsp; This new solution is permanent and no longer kludges
        the DLL.</li>
    </ul>
    <p><b>1.0.49.0 - May 28, 2008</b></p>
    <ul>
      <li>Code merge with SQLite 3.5.9</li>
      <li>Fixed schema problems when querying the TEMP catalog.</li>
      <li>Changed BLOB datatype schema to return IsLong = False instead of True.&nbsp; This
        was preventing DbCommandBuilder from using GUID's and BLOB's as primary keys.</li>
      <li>Fix rollover issue with SQLite3.Reset() using TickCount.</li>
      <li>Fixed SQLiteDataReader to dispose of its command (if called for) before
        closing the connection (when flagged to do so) instead of the other way around.</li>
      <li>Fixed a DbNull error when retrieving items not backed by a table schema.</li>
      <li>Fixed foreign key constraint parsing bug.</li>
      <li>Added FailIfMissing property to the SQLiteConnectionStringBuilder.</li>
      <li>Converted the source projects to Visual Studio 2008.</li>
    </ul>
    <p><b>1.0.48.0 - December 28, 2007</b></p>
    <ul>
      <li>Code merge with SQLite 3.5.4</li>
      <li>Calling SQLiteDataReader.GetFieldType() on a column with no schema information
        and whos first row is initially NULL now returns type Object instead of type DbNull.</li>
      <li>Added support for a new DateTime type, JulianDay.&nbsp; SQLite uses Julian dates
        internally.</li>
      <li>Added a new connection string parameter "Default Timeout" and a corresponding
        method on the SQLiteConnection object to change the default command timeout.&nbsp;
        This is especially useful for changing the timeout on transactions, which use SQLiteCommand
        objects internally and have no ADO.NET-friendly way to adjust the command timeout
        on those commands.</li>
      <li>FTS1 and FTS2 modules were removed from the codebase.&nbsp; Please upgrade all
        full-text indexes to use the FTS3 module.&nbsp;</li>
    </ul>
    <p><b>1.0.47.2 - December 10, 2007</b></p>
    <ul>
      <li>Fixed yet one more bug when closing a database with unfinalized command objects</li>
      <li>Fixed the DataReader's GetFieldType function when dealing with untyped SQLite affinities</li>
    </ul>
    <p><b>1.0.47.1 - December 5, 2007</b></p>
    <ul>
      <li>Fixed a leftover bug from the codemerge with SQLite 3.5.3 that failed to close a database.</li>
      <li>Fixed the broken Compact Framework distribution binary.</li>
      <li>SQLite 3.5.x changed some internal infrastructure pieces in the encryption interface
        which I didn't catch initially.&nbsp; Fixed.&nbsp;</li>
    </ul>
    <p><b>1.0.47.0 - December 4, 2007</b></p>
    <ul>
      <li>Code merge with SQLite 3.5.3</li>
      <li>Added installer support for Visual Studio 2008.&nbsp; Code is still using the
        VS2005 SDK so one or two bells and whistles are missing, but nothing significant.</li>
      <li>This is the last version that the FTS1 and FTS2 extensions will appear.&nbsp;
        Everyone should rebuild their fulltext indexes using the new FTS3 module.&nbsp;
        FTS1 and FTS2 suffer from a design flaw that could cause database corruption with
        certain vacuum operations.</li>
      <li>Fixed pooled connections so they rollback any outstanding transactions before
        going to the pool.&nbsp; </li>
      <li>Fixed the unintended breaking of the TYPES keyword, and mis-typing of untyped
        or indeterminate column types. </li>
      <li>Assert a FileIOPermission() requirement in the static SQLiteFunction constructor.
      </li>
      <li>The CE-only SQLiteFunction.RegisterFunction() is now available on the desktop
        platform for dynamic registration of functions.&nbsp; You must still close and re-open
        a connection in order for the new function to be seen by a connection.</li>
      <li>Fixed the "database is locked" errors by implementing behavioral changes in the
        interop.c file for SQLite.&nbsp; Closing a database force-finalizes any prepared
        statements on the database to ensure the connection is fully closed.&nbsp; This
        was rather tricky because the GC thread could still be finalizing statements itself.
        &nbsp;</li>
      <li>Modifed the mergebin utility to help circumvent a long-standing strong name verification
        bug in the Compact Framework.</li>
    </ul>
    <p><b>1.0.46.0 - September 30, 2007</b></p>
    <ul>
    <li>Fixed faulty logic in type discovery code when using SQLiteDataReader.GetValue().</li>
      <li>Fixed Connection.Open() bug when dealing with :memory: databases.</li>
      <li>Fixed SQLiteCommand.ExecuteScalar() to return a properly-typed value.</li>
      <li>Added support for SQLiteParameter.ResetDbType().</li>
      <li>Added test cases for rigid and flexible type testing.</li>
    </ul>
    <p><b>1.0.45.0 - September 25, 2007</b></p>
    <ul>
    <li><strong>Breaking change in GetSchema("Indexes") </strong>-- MetaDataCollections
      restrictions and identifier parts counts were wrong for this schema and I was using
      the wrong final parameter as the final restriction.&nbsp; Meaning, if you use the
      Indexes schema and are querying for a specific index the array should now be {catalog,
      null, table, index } instead of {catalog, null, table, null, index}</li>
      <li>Fixed some errors in the encryption module, most notably when a non-default page
        size is specified in the connection string.</li>
      <li>Fixed SQLiteDataReader to better handle type-less usage scenarios, which also
        fixes problems with null values and datetimes.</li>
      <li>Fixed the leftover temp files problem on WinCE </li>
      <li>Added connection pooling.&nbsp; The default is disabled for now, but may change
      in the future.&nbsp; Set "Pooling=True" in the connection string to enable it. </li>
      <li>Sped up SQLiteConnection.Open() considerably.</li>
      <li>Added some more robust cleanup code regarding SQLiteFunctions.</li>
      <li>Minor additions to the code to allow for future LINQ integration into the main
        codebase.</li>
      <li>Fixed a long-standing bug in the Open() command of SQLiteConnection which failed
      to honor the documented default behavior of the SQLite.NET provider to open the
      database in "Synchronous=Normal" mode.&nbsp; The default was "Full". </li>
      <li>If Open() fails, it no longer sets the connection state to Broken.&nbsp; It instead
        reverts back to Closed, and cleans up after itself.</li>
      <li>Added several new parameters to the ConnectionString for setting max page count,
        legacy file format, and another called FailIfMissing to raise an error rather than
        create the database file automatically if it does not already exist.</li>
      <li>Fixed some designer toolbox references to the wrong version of the SQLite.Designer</li>
      <li>Fixed a bug in the mergebin utility with regards to COR20 metadata rowsize computations.&nbsp;
      </li>
      <li>Minor documentation corrections &nbsp;&nbsp;</li>
    </ul>
    <p><b>1.0.44.0 - July 21, 2007</b></p>
    <ul>
    <li>Code merge with SQLite 3.4.1</li>
      <li>Fixed a bug in SQLiteConnection.Open() which threw the wrong kind of error in
        the wrong kind of way when a database file could not be opened or created.&nbsp;</li>
      <li>Small enhancements to the TYPES keyword, and added documentation for it in the
        help file.</li>
      <li>Hopefully fixed the occasional SQLITE_BUSY errors that cropped up when starting
        a transaction.&nbsp; Usually occurred in high-contention scenarios, and the underlying
        SQLite engine bypasses the busy handler in this scenario to return immediately.</li>
    </ul>
    <p><b>1.0.43.0 - June 21, 2007</b></p>
    <ul>
    <li>Code merge with SQLite 3.4.0</li>
      <li>Fixed a reuse bug in the SQLiteDataAdapter in conjunction with the SQLiteCommandBuilder.&nbsp;
      It's been there unnoticed for more than a year, so it looks like most folks never
      encountered it. </li>
      <li>Fixed an event handler bug in SQLiteCommandBuilder in which it could fail to unlatch
        from the DataAdapter when reused.&nbsp; Relates to the previous bugfix.</li>
      <li>Fixed a double-dispose bug in SQLiteStatement that triggered a SQLiteException.&nbsp;</li>
    </ul>
    <p><b>1.0.42.0 - June 1, 2007</b></p>
    <ul>
    <li>Code merge with SQLite 3.3.17</li>
      <li>Changed the SQLiteFunction static constructor so it only enumerates loaded modules
        that have referenced the SQLite assembly, which hopefully should cut down dramatically
        the time it takes for that function to execute.&nbsp;</li>
      <li>Added the FTS2 full-text search extension to the project.&nbsp; Look for FTS1
        to disappear within the next couple of revisions.&nbsp;</li>
      <li>Fixed a bug introduced with the finalizers that triggered an error when statements
        ended with a semi-colon or had other non-parsable comments at the end of a statement&nbsp;</li>
      <li>Fixed an intermittent multi-threaded race condition between the garbage collector
        thread and the main application thread which lead to an occasional SQLITE_MISUSE
        error.</li>
      <li>Fixed another issue relating to SQLite's inherent typelessness when dealing with
        aggregate functions which could return Int64 or Double or even String for a given
        row depending on what was aggregated.</li>
      <li>Remembered to recompile the DDEX portion of the engine this time, so Compact Framework
        users can once again use the design-time functionality</li>
    </ul>
    <p><b>1.0.41.0 - April 23, 2007</b></p>
    <ul>
    <li>Code merge with SQLite 3.3.16</li>
      <li>Second go at implementing proper finalizers to cleanup after folks who've forgotten to Dispose() of the SQLite objects</li>
      <li>Enhanced GetSchema(IndexColumns) to provide numeric scale and precision values</li>
      <li>Fixed the column ordinals in GetSchema(IndexColumns) to report the ordinal of the column in the index, not the table</li>
      <li>Fixed a bug whereby parameters named with an empty string (such as String.Empty) were treated like a named parameter instead of an unnamed parameter</li>
    </ul>
    <p><b>1.0.40.0 - January 31, 2007</b></p>
    <ul>
    <li>Code merge with SQLite 3.3.12</li>
      <li>Lots of new code to handle misuse of the library.&nbsp; Implemented finalizers
        where it made sense, fixed numerous garbage collector issues when objects are not
        disposed properly, &nbsp;fixed some object lifetime issues, etc.</li>
      <li>A failed Commit() on a transaction no longer leaves the transaction in an unusable
        state.</li>
    </ul>
    <p><b>1.0.39.1 - January 11, 2007</b></p>
    <ul>
    <li>Fixed a really dumb mistake that for some reason didn't trigger any errors in
      the testcases, whereby commands when associated with a connection were not adding
      or removing themselves from an internal list of commands for that connection --
      causing a "database is locked" error when trying to close the connection.</li>
    </ul>
    <p><b>1.0.39.0 - January 10, 2007</b></p>

      <li>Fixed a multi-threaded race condition bug in the garbage collector when commands
        and/or connections are not properly disposed by the user.</li>
      <li>Switched the encryption's internal deallocation code to use sqlite's built-in
        aux functions instead of modifying the pager.c source to free the crypt block.&nbsp;
        This eliminates the last of the code changes the provider makes to the original
        sqlite engine sources.&nbsp; Props to Ralf Junker for pointing that out.</li>
    </ul>
    <p><b>1.0.38.0 - November 22, 2006</b></p>
    <ul>
    <li>Fixed a bug when using CommandBehavior.KeyInfo whereby integer primary key columns may be duplicated in the results. </li>
      <li>Enhanced the CommandBuilder so that update/delete statements are optimized when the affected table contains unique constraints and
      a primary key is present.</li>
      <li>Fixed a bug in the DataReader when used in conjunction with CommandBehavior.CloseConnection.</li></ul>
    <p><b>1.0.37.0 - November 19, 2006</b></p>
    <ul>
    <li>Added support for CommandBehavior.KeyInfo.&nbsp;
      When specified in a query, additional column(s) will be returned describing the
      key(s) defined for the table(s) selected in the query.&nbsp; This is optimized when
      INTEGER PRIMARY KEY is set for the given tables, but does additional work for other
      kinds of primary keys.</li>
      <li>Removed the default values from SQLiteDataReader.GetTableSchema(), to better follow
        Sql Server's pattern and suppress schema errors when loading the records into a
        dataset/datatable.</li>
      <li>Allow integers to implicitly convert to double/decimal/single.</li></ul>
    <p><b>1.0.36.1 - October 25, 2006</b></p>
    <ul>
    <li>Added support for LONGVARCHAR, SMALLDATE and SMALLDATETIME.  These were actually added in 1.0.36.0 but were undocumented.</li>
    <li>Fixed the embedded helpfile which was accidentally built from old sources. </li>
    <li>Fixed an unfortunate re-entry of a bug in the .36 codebase that caused the provider to "forget" about commands on a connection under certain circumstances.</li>
    </ul>
    <p><b>1.0.36.0 - October 23, 2006</b></p>

    <li>Code merge with SQLite 3.3.8, including support for full-text search via the FTS1
      extension.&nbsp;</li><li>Fixed a bug retrieving data types when UseUtf16Encoding is true.  Side-effect of further merging the common code between the two base classes.</li>
      <li>Fixed a bug with System.Transactions whereby a connection closed/disposed within
        a transaction scope is rolled back and cannot be committed.</li>
      <li>Added more error checking and reporting to transactions to help user's isolate
        the source of transaction failures.</li>
      <li>Implemented a workaround for a Compact Framework issue regarding strong-named
        assemblies containing a PE section with a raw size less than the virtual size.&nbsp;</li>
    </ul>
    <p><b>1.0.35.1 - September 12, 2006</b></p>
    <ul>
    <li>Fixed the TYPES keyword to work when UseUTF16Encoding is true.</li>

      <li>Updated the help documentation.&nbsp;</li>
    </ul>
    <p><b>1.0.35.0 - September 10, 2006</b></p>
    <ul>
    <li>Fixed an infinite loop bug in SQLiteCommand caused when multiple semi-colon separated
      statements in a single command are executed via datareader and one of the statements
      contains a syntax error preventing it from being prepared.&nbsp;</li><li>Added the TYPES preparser keyword to be placed before a SELECT statement to
    aid the wrapper in converting expressions in a subsequent select clause into more
    robust types.&nbsp; Documentation yet to be integrated, but available on the forums.</li>
      <li>Added a new connectionstring parameter "BinaryGUID=true/false" (default is "true").&nbsp;
        When true, guid types are stored in the database as binary blobs to save space.&nbsp;
        Binary has been the default format since 1.0.32.0 but this parameter eases backward
        compatibility.</li>

    <li>Fixed a bug in SQLiteParameterCollection.RemoveAt(namedparam)</li>
    <li>Fixed a bug in SQLiteDataReader introduced in 1.0.30 that broke DateTimes using the Ticks option in the connection string.</li>
      <li>Fixed a bug in the recent changes to guid behavior wherein using a datareader's
        indexer to fetch a guid from a column containing both binary and text guids would
        sometimes return a byte array instead of a guid.</li>
      <li>Enacted a workaround involving typed datasets in Compact Framework projects in
        which it took an excessive amount of time to open a form and generated a lot of
        temporary files in the user's Local Settings\Application Data\Microsoft\VisualStudio\8.0\Assembly

    <li>Added AllowPartiallyTrustedCallers attribute to the assembly</li><li>Added the missing "nchar" type</li>
      <li>Added support for binary Guid's.&nbsp; Guids are now stored as binary by default
        when using parameterized queries.&nbsp; Text guids are still fully supported.</li>
      <li>Fixed a TransactionScope() error that caused the transaction not to be completed.</li>
      <li>Enhanced parameter names so that if they are added to the Parameters collection
        without their prefix character (@ : or $) they are still properly mapped.&nbsp;</li>

      <li>Added hook notification support to SQLiteConnection.&nbsp; Specifically, there
      are three new events on the SQLiteConnection object which are raised when an update/insert/delete
      occurs and when transactions are committed and rolled back.</li><li>Changed SQLiteTransaction to default to BEGIN IMMEDIATE instead of just BEGIN,
    which solves a multithreaded race condition.&nbsp;</li>
      <li>Changed SQLiteDataReader to better support SQLite's typelessness.&nbsp; The data
        reader no longer caches column affinity, but re-evaluates it for each column/row.</li>
      <li>Fixed a bug in Prepare() which caused an intermittant fault due to the code accessing
        the memory of an unpinned variable.&nbsp;</li>
      <li>Fixed a multithreaded lock-retry bug in in SQLiteConnection.Open() and in

    <li>Fixed a parsing bug in SQLiteDataReader.GetSchemaTable() to account for numeric(x,y) datatypes with specified precision and scale</li>
    <li>Fixed a bug in SQLiteConnection.Open() which tried to automatically enlist in an ambient transaction but had not yet set the state of the database to Opened, thereby causing a transaction fault</li>
    <li>Changed SQLiteException to inherit from DbException on the full framework</li>

        prefixing the file with ".\".&nbsp; i.e. "Data Source=.\\mydb.db3"</li>
      <li>Several more changes and enhancements to schemas for better compatibility.</li>
      <li>Fixed several bugs with the 64-bit builds of the provider.&nbsp; The x64 binary
        is now optimized.</li>
      <li>Design-time installer now tries to install the 64-bit builds into the GAC along
        with the 32-bit build.</li>
      <li>Fixed a bug in the SQLiteDataReader.GetSchemaTable() function when used with tables
        containing apostrophes.</li>
      <li>Fixed an XSD-related bug whereby the XSD utility was unable to locate the provider
        and could not generate typed datasets.</li>
      <li>Added NTEXT and STRING datatypes to the list of recognized keywords (used for
        schema retrieval).</li>
      <li>Due to the XSD bug and other potential problems related to external build utilities,
        changes to the installation of the designer have had to be made.&nbsp; The installer
        used to write the DbProviderFactories XML into the devenv.exe.config file and its
        express cousins, but now has to write instead to the machine.config.</li>
      <li>Installer writes to both the 32-bit machine.config and the 64-bit machine.config

    <p><b>1.0.27.1 - February 28, 2006</b></p>
    <ul>
    <li>Fixed a bug when doing data binding in Compact Framework projects that prevented
      you from assigning a typed dataset to a bindingsource.&nbsp; It turns out, the CF
      version of the SQLite provider needs to be flagged as retargetable so it'll work
      in the design-time desktop environment.&nbsp; No changes were made to the desktop
      build, but the revision was bumped on all libraries anyway in order to keep them

      performance.</li>
      <li>Lots of design-time attributes added to the code.&nbsp; The DbDataAdapter, DbCommand,
        and DbConnection objects now have greatly enhanced design-time capabilities when
        added to the toolbox and dropped on a form.</li>
      <li>Lots of Server Explorer enhancements.</li>

    <ul>
    <li>This beta is built from sqlite.org's 3.3.2 beta.</li><li>Eliminated the static linking of mscoree from all binaries.&nbsp; Native projects
      can now use the library without any dependencies on the .NET framework, while managed
      projects continue to be able to use the library normally.</li></ul>
    <p><b>1.0.24.5 beta - January 20, 2006</b></p>
    <ul>
    <li>This beta is built from sqlite.org's 3.3.1 alpha and contains development-in-progress code.&nbsp; Therefore no guarantees
      can be made regarding its suitability for production use.</li>
    <li><strong>You no longer need to distribute 2 files on the CompactFramework.&nbsp;
      You can delete SQLite.Interop.DLL entirely.&nbsp; </strong>I wrote a custom tool
      called "mergebin" (available in the source zip file) which combines the two libraries
      and gets around a glaring defect in the VS2005 linker for ARM processors which doesn't
      allow you to link netmodules.</li>
      <li><strong>x64 and ia64 builds now use the same strong name as the x86 build.</strong>&nbsp;
        This means breaking backward compatibility, but it was necessary in order to allow
        you to drop any of those 3 builds onto a PC and have your .NET program run properly.&nbsp;
        Prior to this, you'd get an error if you built your program using the x86 build,
        and then installed the x64 version on a target machine and tried to run your program
        against it.</li>
      <li>The entire source project has been gone over top to bottom.&nbsp; A debug build
        no longer combines the binaries into a single module, which was preventing proper
        debugging.</li></ul>
    <p><b>1.0.24.4 beta - January 16, 2006</b></p>

    <li>Fixed a bug in the UTF-16 handling code for preparing statements due to a behavioral
      change in SQLite 3.3.0.</li>
      <li>Added pager.c code necessary to cleanup after an encrypted file is closed.</li>
      <li>Fixed an encryption bug that caused a fault when an encrypted file was rolled
        back.</li>
      <li>Modified the testcase code to take advantage of optimizations regarding the use
        of a DbCommandBuilder.&nbsp; DataAdapter insert speed increased dramatically as

    <li>This beta is built from sqlite.org's CVS HEAD (as it appeared at of the date of
      this beta) and contains development-in-progress code.&nbsp; Therefore no guarantees
      can be made regarding its suitability for production use.</li><li>Added support for database encryption at the pager level.&nbsp; Databases
    are encrypted using a 128-bit RC4 stream algorithm.&nbsp; To open an existing encrypted
    database, you may now specify a "Password={password}" text in the ConnectionString,
    or you may call the SQLiteConnection.SetPassword() function to set the password
    on an open connection. &nbsp;To encrypt existing non-encrypted databases or to change
    the password on an encrypted database, you must use the SQLiteConnection.ChangePassword()
    function.&nbsp; If you use SetPassword() instead of specifying a password in the
    connection string, or call ChangePassword() you may use a binary byte array or a
    text string as the password.</li>
      <li>Rewrote the locking implementation for the Compact Framework.&nbsp; It is now
        more robust and incorporates into the SQLite codebase more efficiently than the
        previous CE adaptation.</li>
      <li>Moved some of the embedded schema XML data into a resource file to ease code readability.</li>
      <li>Automated the fixup of the original sqlite codebase's source prior to compiling,

      fixes a bug whereby a multi-statement command that alters the database and subsequently
      references the altered data would fail during Prepare().</li><li>Tightened up the SQLiteDataReader to prevent reading columns before calling
    the first Read() and to prevent reading columns after the last Read().</li>

        introduce a method of retrieving column usage for an arbitrary prepared
        statement, I'll retool this library to be a lightweight function call wrapper
        around the core binary distribution.

          Added a <B>doc</B>
        directory where preliminary documentation on the class library can be found.
        <LI>
          Documented a lot more of the classes internally.
        </LI>
      </UL>
      <P><B>1.0.04 - Feb 24, 2005</B>
      </P>
      <UL>
        <LI>
        Removed the SQLiteContext class and revamped the way UserFunctions work to
        simplify the imlementation.
        <LI>
        Fixed a counting bug in the TestCases class, specifically in the function tests
        where I wasn't resetting the counter and it was consequently reporting
        intrinsic and raw select calls as being much much faster than they actually
        were.&nbsp; The numbers are now much closer to what I expected for performance,
        with .NET user-functions still being the slowest, but only by a small margin.
        <LI>
        Small performance tweaks to SQLiteDataReader.
        <LI>
        Added PageSize to the SQLiteConnectionStringBuilder and subsequently to the
        SQLiteConnection
        <LI>
          Added a PRAGMA encoding=XXX execution statement to the SQLiteConnection after
          opening a connection.
        </LI>
      </UL>
      <P><B>1.0.03 - Feb 23, 2005</B>
      </P>
      <UL>
        <LI>
        Fixed up SQLiteCommandBuilder to correct implementation errors, which resulted
        in an enormous performance boost in the InsertMany test.&nbsp;&nbsp; 10,000 row
        insert that executed in 1500ms now executes in 500ms.
        <LI>
        Fixed several errors in the SQLite3_UTF16 class.&nbsp; ToString() was working
        incorrectly and the Open() method failed to register user defined functions and
        collations.
        <LI>
        Fixed a bug in SQLiteCommand.ClearCommands() whereby only the first statement
        was being properly cleaned up.
        <LI>
        Fixed a bug in SQLiteDataReader whereby calling NextResult() would not properly
        reset the previously-executed command in the sequence.
        <LI>
          Added an InsertManyWithIdentityFetch test, which appends a select clause to
          populate the ID of the last inserted row into the InsertCommand, demonstrating
          ADO.NET's ability to auto-fetch identity columns on insert.
        </LI>
      </UL>
      <P><B>1.0.02 - Feb 21, 2005</B></P>
      <UL>
        <LI>
        Tweaks to the xxx_interop functions that return char *'s, so they also return
        the length.&nbsp; Saves an interop call to get the UTF-8 string length during
        conversion to a .NET string.
        <LI>
        Reworked the whole interop.c thing into interop.h and reduced the code required
        to merge the main sqlite3 codebase.
        <LI>
          Added support for user-defined collations.
        </LI>
      </UL>

      <h1 class="heading">About SQLite.NET</h1>
      <p>This class library is an ADO.NET wrapper around the popular (and free!) 
        SQLite database engine. For information on SQL syntax, features of SQLite and a 
        good understanding of how it works and what it does, I highly recommend heading 
        over to <a target="_blank" href="http://www.sqlite.org">sqlite.org</a> and 
        reading the documentation there.</p>
      <P>The C# provider, the very minor C code modifications to SQLite, documentation and 
        etc&nbsp;were written by <A href="mailto:robert@blackcastlesoft.com">Robert 
          Simpson</A>, and the SourceForge project page can be found <A target="_blank" href="http://sourceforge.net/projects/sqlite-dotnet2">
          here</A>.</P>

      <h1 class="heading">SQLite.NET Provider Features</h1>
      <p>This SQLite provider implements every feature of the underlying SQLite 
        database engine without omission. Here's a brief summary:</p>
      <UL>
        <LI>
        Written from scratch on VS2005/2008 specifically for ADO.NET, implenting all the
        base classes and features recently introduced in the framework, including automatic
        transaction enlistment.<li>Supports the Full and Compact .NET Framework, as well as
          native C/C++ development.&nbsp; 100% binary compatible with the original sqlite3.dll.</li>
        <li>Full support for Mono via a &quot;managed only&quot; provider that runs against the 
          official SQLite 3.6.1 or higher library.</li>
        <li>Full Entity Framework support (ADO.NET 3.5 SP1)</li>
        <li>
        On the Compact Framework, it is faster than Sql Server Mobile.
          SQLite's installed size is a fraction of Sql Mobile's. It uses less memory at runtime,
          runs queries faster, and has a smaller database file size as well. </li>
        <li>Encrypted database support.&nbsp; Encrypted databases are fully encrypted and
          support both binary and cleartext password types. </li>
        <li>Visual Studio 2005/2008 Design-Time Support.&nbsp; You can add a SQLite 
        database to the Servers list, design queries with the Query Designer, 
        drag-and-drop tables onto a Typed DataSet, etc.</li>
            <li>Full SQLite schema editing inside Visual Studio.&nbsp; You can create/edit 
              tables, views, triggers, indexes, check constraints and foreign keys. </li>
        <li>
        Single file redistributable (except Compact Framework).&nbsp; The core sqlite3 codebase and the ADO.NET wrapper 
        are combined into one multi-module assembly. </li>
        <li>Binaries included for Itanium, x64, x86 and ARM processors. </li>
        <li>
        DbProviderFactory support. </li>
        <li>
          Full support for ATTACH'ed databases.&nbsp; Exposed as <i>Catalogs</i>

        automatically re-attached to the new connection. </li>
        <li>
          DbConnection.GetSchema(...) support includes the <i>MetaDataCollections</i>, <i>

        <li>
        Full support for user-defined scalar and aggregate functions, encapsulated into 
        an easy-to-use base class in which only a couple of overrides are necessary to 
        implement new SQL functions. </li>
        <li>
        Full support for user-defined collating sequences, every bit as simple to 
        implement as user-defined functions and uses the same base class. </li>

      <p><b>System.Data.SQLite.DLL</b> is a mixed assembly signed with a strong name 
        in case you want to add it to the Global Assembly Cache (GAC). This is the only DLL required to be redistributed with 
        your SQLite.NET application(s).&nbsp; It 
        comes in&nbsp;3
        flavors: Win32, Itanium and x64 (AMD64).</p>
      <h1 class="heading">Distributing the Binaries (Compact Framework)</h1>
      <p><b>System.Data.SQLite.DLL </b>and <b>SQLite.Interop.XXX.DLL</b> must be 
        deployed on the Compact Framework.&nbsp; The XXX is the build number of the 
        System.Data.SQLite library (e.g. &quot;077&quot;).&nbsp; SQLite.Interop.XXX is a fully

  <!-- 
    Microsoft ResX Schema 
    
    Version 2.0
    
    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.
    
    Example:
    
    ... ado.net/XML headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">2.0</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
        <value>[base64 mime encoded serialized .NET Framework object]</value>
    </data>
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
        <comment>This is a comment</comment>
    </data>
                
    There are any number of "resheader" rows that contain simple 
    name/value pairs.
    
    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.
    
    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:
    
    Note - application/x-microsoft.net.object.binary.base64 is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.
    
    mimetype: application/x-microsoft.net.object.binary.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.
    
    mimetype: application/x-microsoft.net.object.soap.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.bytearray.base64
    value   : The object must be serialized into a byte array 
            : using a System.ComponentModel.TypeConverter

  <!-- 
    Microsoft ResX Schema 
    
    Version 2.0
    
    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.
    
    Example:
    
    ... ado.net/XML headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">2.0</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
        <value>[base64 mime encoded serialized .NET Framework object]</value>
    </data>
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
        <comment>This is a comment</comment>
    </data>
                
    There are any number of "resheader" rows that contain simple 
    name/value pairs.
    
    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.
    
    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:

Optimize SQL.
Write some documentation eg: how to configure the provider via web.config
Dump SQL statements to some sort of human readable format & possibly document them.

? Create a default DB location & make the schema a resource so one can just plunk the provider in and have it just work with little or no config.
? Implement Profile Provider
? Implement a fully dynamic SiteMap Provider so changes to the DB get reflected immediatly

  <!-- 
    Microsoft ResX Schema 
    
    Version 2.0
    
    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.
    
    Example:
    
    ... ado.net/XML headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">2.0</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
        <value>[base64 mime encoded serialized .NET Framework object]</value>
    </data>
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
        <comment>This is a comment</comment>
    </data>
                
    There are any number of "resheader" rows that contain simple 
    name/value pairs.
    
    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.
    
    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:
    
    Note - application/x-microsoft.net.object.binary.base64 is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.
    
    mimetype: application/x-microsoft.net.object.binary.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.
    
    mimetype: application/x-microsoft.net.object.soap.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.bytearray.base64
    value   : The object must be serialized into a byte array 
            : using a System.ComponentModel.TypeConverter
            : and then encoded with base64 encoding.

  <!-- 
    Microsoft ResX Schema 
    
    Version 2.0
    
    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.
    
    Example:
    
    ... ado.net/XML headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">2.0</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
        <value>[base64 mime encoded serialized .NET Framework object]</value>
    </data>
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
        <comment>This is a comment</comment>
    </data>
                
    There are any number of "resheader" rows that contain simple 
    name/value pairs.
    
    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.
    
    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:
    
    Note - application/x-microsoft.net.object.binary.base64 is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.
    
    mimetype: application/x-microsoft.net.object.binary.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.
    
    mimetype: application/x-microsoft.net.object.soap.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.bytearray.base64
    value   : The object must be serialized into a byte array 
            : using a System.ComponentModel.TypeConverter
            : and then encoded with base64 encoding.

  <!-- 
    Microsoft ResX Schema 
    
    Version 2.0
    
    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.
    
    Example:
    
    ... ado.net/XML headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">2.0</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
        <value>[base64 mime encoded serialized .NET Framework object]</value>
    </data>
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
        <comment>This is a comment</comment>
    </data>
                
    There are any number of "resheader" rows that contain simple 
    name/value pairs.
    
    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.
    
    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:
    
    Note - application/x-microsoft.net.object.binary.base64 is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.
    
    mimetype: application/x-microsoft.net.object.binary.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.
    
    mimetype: application/x-microsoft.net.object.soap.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.bytearray.base64
    value   : The object must be serialized into a byte array 
            : using a System.ComponentModel.TypeConverter
            : and then encoded with base64 encoding.

  <!-- 
    Microsoft ResX Schema 
    
    Version 2.0
    
    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.
    
    Example:
    
    ... ado.net/XML headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">2.0</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
        <value>[base64 mime encoded serialized .NET Framework object]</value>
    </data>
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
        <comment>This is a comment</comment>
    </data>
                
    There are any number of "resheader" rows that contain simple 
    name/value pairs.
    
    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.
    
    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:
    
    Note - application/x-microsoft.net.object.binary.base64 is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.
    
    mimetype: application/x-microsoft.net.object.binary.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.
    
    mimetype: application/x-microsoft.net.object.soap.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.bytearray.base64
    value   : The object must be serialized into a byte array 
            : using a System.ComponentModel.TypeConverter
            : and then encoded with base64 encoding.

  <!-- 
    Microsoft ResX Schema 
    
    Version 2.0
    
    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.
    
    Example:
    
    ... ado.net/XML headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">2.0</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
        <value>[base64 mime encoded serialized .NET Framework object]</value>
    </data>
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
        <comment>This is a comment</comment>
    </data>
                
    There are any number of "resheader" rows that contain simple 
    name/value pairs.
    
    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.
    
    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:
    
    Note - application/x-microsoft.net.object.binary.base64 is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.
    
    mimetype: application/x-microsoft.net.object.binary.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.
    
    mimetype: application/x-microsoft.net.object.soap.base64
    value   : The object must be serialized with

  <!-- 
    Microsoft ResX Schema 
    
    Version 2.0
    
    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.
    
    Example:
    
    ... ado.net/XML headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">2.0</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
        <value>[base64 mime encoded serialized .NET Framework object]</value>
    </data>
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
        <comment>This is a comment</comment>
    </data>
                
    There are any number of "resheader" rows that contain simple 
    name/value pairs.
    
    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.
    
    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:
    
    Note - application/x-microsoft.net.object.binary.base64 is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.
    
    mimetype: application/x-microsoft.net.object.binary.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.
    
    mimetype: application/x-microsoft.net.object.soap.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.bytearray.base64
    value   : The object must be serialized into a byte array 
            : using a System.ComponentModel.TypeConverter
            : and then encoded with base64 encoding.

    Microsoft ResX Schema 
    
    Version 2.0
    
    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.
    
    Example:
    
    ... ado.net/XML headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">2.0</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
        <value>[base64 mime encoded serialized .NET Framework object]</value>
    </data>
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
        <comment>This is a comment</comment>
    </data>
                
    There are any number of "resheader" rows that contain simple 
    name/value pairs.
    
    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.
    
    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:
    
    Note - application/x-microsoft.net.object.binary.base64 is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.
    
    mimetype: application/x-microsoft.net.object.binary.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.
    
    mimetype: application/x-microsoft.net.object.soap.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.bytearray.base64
    value   : The object must be serialized into a byte array 
            : using a System.ComponentModel.TypeConverter
            : and then encoded with base64 encoding.

/*
** Set or clear the access authorization function.
**
** The access authorization function is be called during the compilation
** phase to verify that the user has read and/or write access permission on
** various fields of the database.  The first argument to the auth function
** is a copy of the 3rd argument to this routine.  The second argument
** to the auth function is one of these constants:
**
**       SQLITE_CREATE_INDEX
**       SQLITE_CREATE_TABLE
**       SQLITE_CREATE_TEMP_INDEX
**       SQLITE_CREATE_TEMP_TABLE
**       SQLITE_CREATE_TEMP_TRIGGER
**       SQLITE_CREATE_TEMP_VIEW
**       SQLITE_CREATE_TRIGGER
**       SQLITE_CREATE_VIEW
**       SQLITE_DELETE
**       SQLITE_DROP_INDEX
**       SQLITE_DROP_TABLE
**       SQLITE_DROP_TEMP_INDEX
**       SQLITE_DROP_TEMP_TABLE
**       SQLITE_DROP_TEMP_TRIGGER
**       SQLITE_DROP_TEMP_VIEW
**       SQLITE_DROP_TRIGGER
**       SQLITE_DROP_VIEW
**       SQLITE_INSERT
**       SQLITE_PRAGMA
**       SQLITE_READ
**       SQLITE_SELECT
**       SQLITE_TRANSACTION
**       SQLITE_UPDATE
**
** The third and fourth arguments to the auth function are the name of
** the table and the column that are being accessed.  The auth function
** should return either SQLITE_OK, SQLITE_DENY, or SQLITE_IGNORE.  If
** SQLITE_OK is returned, it means that access is allowed.  SQLITE_DENY
** means that the SQL statement will never-run - the sqlite3_exec() call
** will return with an error.  SQLITE_IGNORE means that the SQL statement
** should run but attempts to read the specified column will return NULL
** and attempts to write the column will be ignored.
**
** Setting the auth function to NULL disables this hook.  The default
** setting of the auth function is NULL.

**
** This file implements a external (disk-based) database using BTrees.
** For a detailed discussion of BTrees, refer to
**
**     Donald E. Knuth, THE ART OF COMPUTER PROGRAMMING, Volume 3:
**     "Sorting And Searching", pages 473-480. Addison-Wesley
**     Publishing Company, Reading, Massachusetts.
**
** The basic idea is that each page of the file contains N database
** entries and N+1 pointers to subpages.
**
**   ----------------------------------------------------------------
**   |  Ptr(0) | Key(0) | Ptr(1) | Key(1) | ... | Key(N) | Ptr(N+1) |
**   ----------------------------------------------------------------
**
** All of the keys on the page that Ptr(0) points to have values less
** than Key(0).  All of the keys on page Ptr(1) and its subpages have
** values greater than Key(0) and less than Key(1).  All of the keys
** on Ptr(N+1) and its subpages have values greater than Key(N).  And
** so forth.
**
** Finding a particular key requires reading O(log(M)) pages from the 
** disk where M is the number of entries in the tree.
**
** In this implementation, a single file can hold one or more separate 
** BTrees.  Each BTree is identified by the index of its root page.  The
** key and data for any entry are combined to form the "payload".  A
** fixed amount of payload can be carried directly on the database
** page.  If the payload is larger than the preset amount then surplus
** bytes are stored on overflow pages.  The payload for an entry
** and the preceding pointer are combined to form a "Cell".  Each 
** page has a small header which contains the Ptr(N+1) pointer and other
** information such as the size of key and data.
**
** FORMAT DETAILS
**
** The file is divided into pages.  The first page is called page 1,
** the second is page 2, and so forth.  A page number of zero indicates
** "no such page".  The page size can be anything between 512 and 65536.
** Each page can be either a btree page, a freelist page or an overflow
** page.
**
** The first page is always a btree page.  The first 100 bytes of the first
** page contain a special header (the "file header") that describes the file.
** The format of the file header is as follows:
**
**   OFFSET   SIZE    DESCRIPTION
**      0      16     Header string: "SQLite format 3\000"
**     16       2     Page size in bytes.  
**     18       1     File format write version
**     19       1     File format read version
**     20       1     Bytes of unused space at the end of each page
**     21       1     Max embedded payload fraction
**     22       1     Min embedded payload fraction
**     23       1     Min leaf payload fraction
**     24       4     File change counter
**     28       4     Reserved for future use
**     32       4     First freelist page
**     36       4     Number of freelist pages in the file
**     40      60     15 4-byte meta values passed to higher layers
**
** All of the integer values are big-endian (most significant byte first).
**
** The file change counter is incremented when the database is changed more
** than once within the same second.  This counter, together with the
** modification time of the file, allows other processes to know
** when the file has changed and thus when they need to flush their
** cache.
**
** The max embedded payload fraction is the amount of the total usable
** space in a page that can be consumed by a single cell for standard
** B-tree (non-LEAFDATA) tables.  A value of 255 means 100%.  The default
** is to limit the maximum cell size so that at least 4 cells will fit
** on one page.  Thus the default max embedded payload fraction is 64.
**
** If the payload for a cell is larger than the max payload, then extra
** payload is spilled to overflow pages.  Once an overflow page is allocated,
** as many bytes as possible are moved into the overflow pages without letting
** the cell size drop below the min embedded payload fraction.
**
** The min leaf payload fraction is like the min embedded payload fraction
** except that it applies to leaf nodes in a LEAFDATA tree.  The maximum
** payload fraction for a LEAFDATA tree is always 100% (or 255) and it
** not specified in the header.
**
** Each btree pages is divided into three sections:  The header, the
** cell pointer array, and the cell area area.  Page 1 also has a 100-byte
** file header that occurs before the page header.
**
**      |----------------|
**      | file header    |   100 bytes.  Page 1 only.
**      |----------------|
**      | page header    |   8 bytes for leaves.  12 bytes for interior nodes
**      |----------------|
**      | cell pointer   |   |  2 bytes per cell.  Sorted order.
**      | array          |   |  Grows downward
**      |                |   v
**      |----------------|
**      | unallocated    |
**      | space          |
**      |----------------|   ^  Grows upwards
**      | cell content   |   |  Arbitrary order interspersed with freeblocks.
**      | area           |   |  and free space fragments.
**      |----------------|
**
** The page headers looks like this:
**
**   OFFSET   SIZE     DESCRIPTION
**      0       1      Flags. 1: intkey, 2: zerodata, 4: leafdata, 8: leaf
**      1       2      byte offset to the first freeblock
**      3       2      number of cells on this page
**      5       2      first byte of the cell content area
**      7       1      number of fragmented free bytes
**      8       4      Right child (the Ptr(N+1) value).  Omitted on leaves.
**
** The flags define the format of this btree page.  The leaf flag means that
** this page has no children.  The zerodata flag means that this page carries
** only keys and no data.  The intkey flag means that the key is a integer
** which is stored in the key size entry of the cell header rather than in
** the payload area.
**
** The cell pointer array begins on the first byte after the page header.
** The cell pointer array contains zero or more 2-byte numbers which are
** offsets from the beginning of the page to the cell content in the cell
** content area.  The cell pointers occur in sorted order.  The system strives
** to keep free space after the last cell pointer so that new cells can
** be easily added without having to defragment the page.
**
** Cell content is stored at the very end of the page and grows toward the
** beginning of the page.
**
** Unused space within the cell content area is collected into a linked list of
** freeblocks.  Each freeblock is at least 4 bytes in size.  The byte offset
** to the first freeblock is given in the header.  Freeblocks occur in
** increasing order.  Because a freeblock must be at least 4 bytes in size,
** any group of 3 or fewer unused bytes in the cell content area cannot
** exist on the freeblock chain.  A group of 3 or fewer free bytes is called
** a fragment.  The total number of bytes in all fragments is recorded.
** in the page header at offset 7.
**
**    SIZE    DESCRIPTION
**      2     Byte offset of the next freeblock
**      2     Bytes in this freeblock
**
** Cells are of variable length.  Cells are stored in the cell content area at
** the end of the page.  Pointers to the cells are in the cell pointer array
** that immediately follows the page header.  Cells is not necessarily
** contiguous or in order, but cell pointers are contiguous and in order.
**
** Cell content makes use of variable length integers.  A variable
** length integer is 1 to 9 bytes where the lower 7 bits of each 
** byte are used.  The integer consists of all bytes that have bit 8 set and
** the first byte with bit 8 clear.  The most significant byte of the integer
** appears first.  A variable-length integer may not be more than 9 bytes long.
** As a special case, all 8 bytes of the 9th byte are used as data.  This
** allows a 64-bit integer to be encoded in 9 bytes.
**
**    0x00                      becomes  0x00000000
**    0x7f                      becomes  0x0000007f
**    0x81 0x00                 becomes  0x00000080
**    0x82 0x00                 becomes  0x00000100
**    0x80 0x7f                 becomes  0x0000007f
**    0x8a 0x91 0xd1 0xac 0x78  becomes  0x12345678
**    0x81 0x81 0x81 0x81 0x01  becomes  0x10204081
**
** Variable length integers are used for rowids and to hold the number of
** bytes of key and data in a btree cell.
**
** The content of a cell looks like this:
**
**    SIZE    DESCRIPTION
**      4     Page number of the left child. Omitted if leaf flag is set.
**     var    Number of bytes of data. Omitted if the zerodata flag is set.
**     var    Number of bytes of key. Or the key itself if intkey flag is set.
**      *     Payload
**      4     First page of the overflow chain.  Omitted if no overflow
**
** Overflow pages form a linked list.  Each page except the last is completely
** filled with data (pagesize - 4 bytes).  The last page can have as little
** as 1 byte of data.
**
**    SIZE    DESCRIPTION
**      4     Page number of next overflow page
**      *     Data
**
** Freelist pages come in two subtypes: trunk pages and leaf pages.  The
** file header points to first in a linked list of trunk page.  Each trunk
** page points to multiple leaf pages.  The content of a leaf page is
** unspecified.  A trunk page looks like this:
**
**    SIZE    DESCRIPTION
**      4     Page number of next trunk page
**      4     Number of leaf pointers on this page
**      *     zero or more pages numbers of leaves

** 2:  No other cursors may be open with wrFlag==0 on the same table
**

**

** on a table with wrFlag==0, that prevents all other cursors from
** writing to that table.  This is a kind of "read-lock".  When a cursor
** is opened with wrFlag==0 it is guaranteed that the table will not
** change as long as the cursor is open.  This allows the cursor to
** do a sequential scan of the table without having to worry about
** entries being inserted or deleted during the scan.  Cursors should
** be opened with wrFlag==0 only if this read-lock property is needed.
** That is to say, cursors should be opened with wrFlag==0 only if they
** intend to use the sqlite3BtreeNext() system call.  All other cursors
** should be opened with wrFlag==1 even if they never really intend
** to write.
** 
** No checking is done to make sure that page iTable really is the
** root page of a b-tree.  If it is not, then the cursor acquired
** will not work correctly.
**
** The comparison function must be logically the same for every cursor
** on a particular table.  Changing the comparison function will result
** in incorrect operations.  If the comparison function is NULL, a
** default comparison function is used.  The comparison function is
** always ignored for INTKEY tables.

/*
This library will provide common mathematical and string functions in
SQL queries using the operating system math library.  It includes the
following functions:

Math: acos, asin, atan, atn2, atan2, acosh, asinh, atanh, difference,
degrees, radians, cos, sin, tan, cot, cosh, sinh, tanh, coth, exp,
log, log10, power, sign, sqrt, square, ceil, floor, pi.

String: replicate, charindex, leftstr, rightstr, ltrim, rtrim, trim,
replace, reverse, proper, padl, padr, padc, strfilter.

Aggregate: stdev, variance, mode, median, lower_quartile,
upper_quartile.

The string functions ltrim, rtrim, trim, replace are included in
recent versions of SQLite and so by default do not build.

Instructions:
1) Compile with
   Linux:
     gcc -fPIC -lm -shared extension-functions.c -o libsqlitefunctions.so
   Mac OS X:
     gcc -fno-common -dynamiclib extension-functions.c -o libsqlitefunctions.dylib
   (You may need to add flags
    -I /opt/local/include/ -L/opt/local/lib -lsqlite3
    if your sqlite3 is installed from Mac ports, or
    -I /sw/include/ -L/sw/lib -lsqlite3
    if installed with Fink.)
2) In your application, call sqlite3_enable_load_extension(db,1) to
   allow loading external libraries.  Then load the library libsqlitefunctions
   using sqlite3_load_extension; the third argument should be 0.
   See http://www.sqlite.org/cvstrac/wiki?p=LoadableExtensions.
3) Use, for example:
   SELECT cos(radians(inclination)) FROM satsum WHERE satnum = 25544;

Note: Loading extensions is by default prohibited as a
security measure; see "Security Considerations" in
http://www.sqlite.org/cvstrac/wiki?p=LoadableExtensions.
If the sqlite3 program and library are built this
way, you cannot use these functions from the program, you 
must write your own program using the sqlite3 API, and call
sqlite3_enable_load_extension as described above.

If the program is built so that loading extensions is permitted,
the following will work:
sqlite> SELECT load_extension('./libsqlitefunctions.so');
sqlite> select cos(radians(45));
0.707106781186548

Alterations:
The instructions are for Linux or Mac OS X; users of other OSes may
need to modify this procedure.  In particular, if your math library
lacks one or more of the needed trig or log functions, comment out the
appropriate HAVE_ #define at the top of file.  If you do not
wish to make a loadable module, comment out the define for
COMPILE_SQLITE_EXTENSIONS_AS_LOADABLE_MODULE.  If you are using a
version of SQLite without the trim functions and replace, comment out
the HAVE_TRIM #define.

History:
2008-06-13 Change to instructions to indicate use of the math library
and that program might work.
2007-10-01 Minor clarification to instructions.
2007-09-29 Compilation as loadable module is optional with
COMPILE_SQLITE_EXTENSIONS_AS_LOADABLE_MODULE.
2007-09-28 Use sqlite3_extension_init and macros
SQLITE_EXTENSION_INIT1, SQLITE_EXTENSION_INIT2, so that it works with
sqlite3_load_extension.  Thanks to Eric Higashino and Joe Wilson.
New instructions for Mac compilation.
2007-09-17 With help from Joe Wilson and Nuno Luca, made use of
external interfaces so that compilation is no longer dependent on
SQLite source code.  Merged source, header, and README into a single
file.  Added casts so that Mac will compile without warnings (unsigned
and signed char).
2007-09-05 Included some definitions from sqlite 3.3.13 so that this
will continue to work in newer versions of sqlite.  Completed
description of functions available.
2007-03-27 Revised description.
2007-03-23 Small cleanup and a bug fix on the code.  This was mainly
letting errno flag errors encountered in the math library and checking
the result, rather than pre-checking.  This fixes a bug in power that
would cause an error if any non-positive number was raised to any
power.
2007-02-07 posted by Mikey C to sqlite mailing list.

** without running any subsequent SQL statements.
**
** ^The 2nd argument to the sqlite3_exec() callback function is the

** This object defines the methods used to perform various operations
** against the open file represented by the [sqlite3_file] object.
**
** If the [sqlite3_vfs.xOpen] method sets the sqlite3_file.pMethods element 
** to a non-NULL pointer, then the sqlite3_io_methods.xClose method
** may be invoked even if the [sqlite3_vfs.xOpen] reported that it failed.  The
** only way to prevent a call to xClose following a failed [sqlite3_vfs.xOpen]
** is for the [sqlite3_vfs.xOpen] to set the sqlite3_file.pMethods element
** to NULL.
**
** The flags argument to xSync may be one of [SQLITE_SYNC_NORMAL] or
** [SQLITE_SYNC_FULL].  The first choice is the normal fsync().
** The second choice is a Mac OS X style fullsync.  The [SQLITE_SYNC_DATAONLY]
** flag may be ORed in to indicate that only the data of the file
** and not its inode needs to be synced.
**
** The integer values to xLock() and xUnlock() are one of
** <ul>
** <li> [SQLITE_LOCK_NONE],
** <li> [SQLITE_LOCK_SHARED],
** <li> [SQLITE_LOCK_RESERVED],
** <li> [SQLITE_LOCK_PENDING], or
** <li> [SQLITE_LOCK_EXCLUSIVE].
** </ul>
** xLock() increases the lock. xUnlock() decreases the lock.
** The xCheckReservedLock() method checks whether any database connection,
** either in this process or in some other process, is holding a RESERVED,
** PENDING, or EXCLUSIVE lock on the file.  It returns true
** if such a lock exists and false otherwise.
**
** The xFileControl() method is a generic interface that allows custom
** VFS implementations to directly control an open file using the
** [sqlite3_file_control()] interface.  The second "op" argument is an
** integer opcode.  The third argument is a generic pointer intended to
** point to a structure that may contain arguments or space in which to
** write return values.  Potential uses for xFileControl() might be
** functions to enable blocking locks with timeouts, to change the
** locking strategy (for example to use dot-file locks), to inquire
** about the status of a lock, or to break stale locks.  The SQLite
** core reserves all opcodes less than 100 for its own use.
** A [SQLITE_FCNTL_LOCKSTATE | list of opcodes] less than 100 is available.
** Applications that define a custom xFileControl method should use opcodes
** greater than 100 to avoid conflicts.  VFS implementations should
** return [SQLITE_NOTFOUND] for file control opcodes that they do not
** recognize.
**
** The xSectorSize() method returns the sector size of the
** device that underlies the file.  The sector size is the
** minimum write that can be performed without disturbing

** file space based on this hint in order to help writes to the database
** file run faster.
**
** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS
** extends and truncates the database file in chunks of a size specified
** by the user. The fourth argument to [sqlite3_file_control()] should 
** point to an integer (type int) containing the new chunk-size to use
** for the nominated database. Allocating database file space in large
** chunks (say 1MB at a time), may reduce file-system fragmentation and
** improve performance on some systems.
**
** The [SQLITE_FCNTL_FILE_POINTER] opcode is used to obtain a pointer
** to the [sqlite3_file] object associated with a particular database
** connection.  See the [sqlite3_file_control()] documentation for
** additional information.
**
** ^(The [SQLITE_FCNTL_SYNC_OMITTED] opcode is generated internally by
** SQLite and sent to all VFSes in place of a call to the xSync method
** when the database connection has [PRAGMA synchronous] set to OFF.)^
** Some specialized VFSes need this signal in order to operate correctly
** when [PRAGMA synchronous | PRAGMA synchronous=OFF] is set, but most 
** VFSes do not need this signal and should silently ignore this opcode.
** Applications should not call [sqlite3_file_control()] with this
** opcode as doing so may disrupt the operation of the specialized VFSes
** that do require it.  
**
** ^The [SQLITE_FCNTL_WIN32_AV_RETRY] opcode is used to configure automatic
** retry counts and intervals for certain disk I/O operations for the
** windows [VFS] in order to work to provide robustness against
** anti-virus programs.  By default, the windows VFS will retry file read,
** file write, and file delete operations up to 10 times, with a delay
** of 25 milliseconds before the first retry and with the delay increasing
** by an additional 25 milliseconds with each subsequent retry.  This
** opcode allows those to values (10 retries and 25 milliseconds of delay)
** to be adjusted.  The values are changed for all database connections
** within the same process.  The argument is a pointer to an array of two
** integers where the first integer i the new retry count and the second
** integer is the delay.  If either integer is negative, then the setting
** is not changed but instead the prior value of that setting is written
** into the array entry, allowing the current retry settings to be
** interrogated.  The zDbName parameter is ignored.
**
** ^The [SQLITE_FCNTL_PERSIST_WAL] opcode is used to set or query the
** persistent [WAL | Write AHead Log] setting.  By default, the auxiliary
** write ahead log and shared memory files used for transaction control
** are automatically deleted when the latest connection to the database
** closes.  Setting persistent WAL mode causes those files to persist after
** close.  Persisting the files is useful when other processes that do not
** have write permission on the directory containing the database file want
** to read the database file, as the WAL and shared memory files must exist
** in order for the database to be readable.  The fourth parameter to
** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
** That integer is 0 to disable persistent WAL mode or 1 to enable persistent
** WAL mode.  If the integer is -1, then it is overwritten with the current
** WAL persistence setting.
**
** ^The [SQLITE_FCNTL_OVERWRITE] opcode is invoked by SQLite after opening
** a write transaction to indicate that, unless it is rolled back for some
** reason, the entire database file will be overwritten by the current 
** transaction. This is used by VACUUM operations.

** deals with pointers to the [sqlite3_mutex] object.
**

*/
typedef struct sqlite3_mutex sqlite3_mutex;

/*
** CAPI3REF: OS Interface Object
**
** An instance of the sqlite3_vfs object defines the interface between
** the SQLite core and the underlying operating system.  The "vfs"
** in the name of the object stands for "virtual file system".  See
** the [VFS | VFS documentation] for further information.
**
** The value of the iVersion field is initially 1 but may be larger in
** future versions of SQLite.  Additional fields may be appended to this
** object when the iVersion value is increased.  Note that the structure
** of the sqlite3_vfs object changes in the transaction between
** SQLite version 3.5.9 and 3.6.0 and yet the iVersion field was not
** modified.
**
** The szOsFile field is the size of the subclassed [sqlite3_file]
** structure used by this VFS.  mxPathname is the maximum length of
** a pathname in this VFS.
**
** Registered sqlite3_vfs objects are kept on a linked list formed by
** the pNext pointer.  The [sqlite3_vfs_register()]
** and [sqlite3_vfs_unregister()] interfaces manage this list
** in a thread-safe way.  The [sqlite3_vfs_find()] interface
** searches the list.  Neither the application code nor the VFS
** implementation should use the pNext pointer.
**
** The pNext field is the only field in the sqlite3_vfs
** structure that SQLite will ever modify.  SQLite will only access
** or modify this field while holding a particular static mutex.
** The application should never modify anything within the sqlite3_vfs
** object once the object has been registered.
**
** The zName field holds the name of the VFS module.  The name must
** be unique across all VFS modules.
**
** [[sqlite3_vfs.xOpen]]
** ^SQLite guarantees that the zFilename parameter to xOpen
** is either a NULL pointer or string obtained
** from xFullPathname() with an optional suffix added.
** ^If a suffix is added to the zFilename parameter, it will
** consist of a single "-" character followed by no more than
** 10 alphanumeric and/or "-" characters.
** ^SQLite further guarantees that
** the string will be valid and unchanged until xClose() is
** called. Because of the previous sentence,
** the [sqlite3_file] can safely store a pointer to the
** filename if it needs to remember the filename for some reason.
** If the zFilename parameter to xOpen is a NULL pointer then xOpen
** must invent its own temporary name for the file.  ^Whenever the 
** xFilename parameter is NULL it will also be the case that the
** flags parameter will include [SQLITE_OPEN_DELETEONCLOSE].
**
** The flags argument to xOpen() includes all bits set in
** the flags argument to [sqlite3_open_v2()].  Or if [sqlite3_open()]
** or [sqlite3_open16()] is used, then flags includes at least
** [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE]. 
** If xOpen() opens a file read-only then it sets *pOutFlags to
** include [SQLITE_OPEN_READONLY].  Other bits in *pOutFlags may be set.
**
** ^(SQLite will also add one of the following flags to the xOpen()
** call, depending on the object being opened:
**
** <ul>
** <li>  [SQLITE_OPEN_MAIN_DB]
** <li>  [SQLITE_OPEN_MAIN_JOURNAL]
** <li>  [SQLITE_OPEN_TEMP_DB]
** <li>  [SQLITE_OPEN_TEMP_JOURNAL]
** <li>  [SQLITE_OPEN_TRANSIENT_DB]
** <li>  [SQLITE_OPEN_SUBJOURNAL]
** <li>  [SQLITE_OPEN_MASTER_JOURNAL]
** <li>  [SQLITE_OPEN_WAL]
** </ul>)^
**
** The file I/O implementation can use the object type flags to
** change the way it deals with files.  For example, an application
** that does not care about crash recovery or rollback might make
** the open of a journal file a no-op.  Writes to this journal would
** also be no-ops, and any attempt to read the journal would return
** SQLITE_IOERR.  Or the implementation might recognize that a database
** file will be doing page-aligned sector reads and writes in a random
** order and set up its I/O subsystem accordingly.
**
** SQLite might also add one of the following flags to the xOpen method:
**
** <ul>
** <li> [SQLITE_OPEN_DELETEONCLOSE]
** <li> [SQLITE_OPEN_EXCLUSIVE]
** </ul>
**
** The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
** deleted when it is closed.  ^The [SQLITE_OPEN_DELETEONCLOSE]
** will be set for TEMP databases and their journals, transient
** databases, and subjournals.
**
** ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction
** with the [SQLITE_OPEN_CREATE] flag, which are both directly
** analogous to the O_EXCL and O_CREAT flags of the POSIX open()
** API.  The SQLITE_OPEN_EXCLUSIVE flag, when paired with the 
** SQLITE_OPEN_CREATE, is used to indicate that file should always
** be created, and that it is an error if it already exists.
** It is <i>not</i> used to indicate the file should be opened 
** for exclusive access.
**
** ^At least szOsFile bytes of memory are allocated by SQLite
** to hold the  [sqlite3_file] structure passed as the third
** argument to xOpen.  The xOpen method does not have to
** allocate the structure; it should just fill it in.  Note that
** the xOpen method must set the sqlite3_file.pMethods to either
** a valid [sqlite3_io_methods] object or to NULL.  xOpen must do
** this even if the open fails.  SQLite expects that the sqlite3_file.pMethods
** element will be valid after xOpen returns regardless of the success
** or failure of the xOpen call.
**
** [[sqlite3_vfs.xAccess]]
** ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
** to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to
** test whether a file is readable and writable, or [SQLITE_ACCESS_READ]
** to test whether a file is at least readable.   The file can be a
** directory.
**
** ^SQLite will always allocate at least mxPathname+1 bytes for the
** output buffer xFullPathname.  The exact size of the output buffer
** is also passed as a parameter to both  methods. If the output buffer
** is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is
** handled as a fatal error by SQLite, vfs implementations should endeavor
** to prevent this by setting mxPathname to a sufficiently large value.
**
** The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64()
** interfaces are not strictly a part of the filesystem, but they are
** included in the VFS structure for completeness.
** The xRandomness() function attempts to return nBytes bytes
** of good-quality randomness into zOut.  The return value is
** the actual number of bytes of randomness obtained.
** The xSleep() method causes the calling thread to sleep for at
** least the number of microseconds given.  ^The xCurrentTime()
** method returns a Julian Day Number for the current date and time as
** a floating point value.
** ^The xCurrentTimeInt64() method returns, as an integer, the Julian
** Day Number multiplied by 86400000 (the number of milliseconds in 
** a 24-hour day).  
** ^SQLite will use the xCurrentTimeInt64() method to get the current
** date and time if that method is available (if iVersion is 2 or 
** greater and the function pointer is not NULL) and will fall back
** to xCurrentTime() if xCurrentTimeInt64() is unavailable.
**
** ^The xSetSystemCall(), xGetSystemCall(), and xNestSystemCall() interfaces
** are not used by the SQLite core.  These optional interfaces are provided
** by some VFSes to facilitate testing of the VFS code. By overriding 
** system calls with functions under its control, a test program can
** simulate faults and error conditions that would otherwise be difficult
** or impossible to induce.  The set of system calls that can be overridden
** varies from one VFS to another, and from one version of the same VFS to the
** next.  Applications that use these interfaces must be prepared for any
** or all of these interfaces to be NULL or for their behavior to change
** from one release to the next.  Applications must not attempt to access
** any of these methods if the iVersion of the VFS is less than 3.

** CAPI3REF: Initialize The SQLite Library
**
** ^The sqlite3_initialize() routine initializes the

** deallocates any resources that were allocated by sqlite3_initialize().
** These routines are designed to aid in process initialization and
** shutdown on embedded systems.  Workstation applications using
** SQLite normally do not need to invoke either of these routines.
**
** A call to sqlite3_initialize() is an "effective" call if it is
** the first time sqlite3_initialize() is invoked during the lifetime of
** the process, or if it is the first time sqlite3_initialize() is invoked
** following a call to sqlite3_shutdown().  ^(Only an effective call
** of sqlite3_initialize() does any initialization.  All other calls
** are harmless no-ops.)^
**
** A call to sqlite3_shutdown() is an "effective" call if it is the first
** call to sqlite3_shutdown() since the last sqlite3_initialize().  ^(Only
** an effective call to sqlite3_shutdown() does any deinitialization.
** All other valid calls to sqlite3_shutdown() are harmless no-ops.)^
**
** The sqlite3_initialize() interface is threadsafe, but sqlite3_shutdown()
** is not.  The sqlite3_shutdown() interface must only be called from a
** single thread.  All open [database connections] must be closed and all
** other SQLite resources must be deallocated prior to invoking
** sqlite3_shutdown().
**
** Among other things, ^sqlite3_initialize() will invoke
** sqlite3_os_init().  Similarly, ^sqlite3_shutdown()
** will invoke sqlite3_os_end().
**
** ^The sqlite3_initialize() routine returns [SQLITE_OK] on success.
** ^If for some reason, sqlite3_initialize() is unable to initialize
** the library (perhaps it is unable to allocate a needed resource such
** as a mutex) it returns an [error code] other than [SQLITE_OK].
**
** ^The sqlite3_initialize() routine is called internally by many other
** SQLite interfaces so that an application usually does not need to
** invoke sqlite3_initialize() directly.  For example, [sqlite3_open()]
** calls sqlite3_initialize() so the SQLite library will be automatically
** initialized when [sqlite3_open()] is called if it has not be initialized
** already.  ^However, if SQLite is compiled with the [SQLITE_OMIT_AUTOINIT]
** compile-time option, then the automatic calls to sqlite3_initialize()
** are omitted and the application must call sqlite3_initialize() directly
** prior to using any other SQLite interface.  For maximum portability,
** it is recommended that applications always invoke sqlite3_initialize()
** directly prior to using any other SQLite interface.  Future releases
** of SQLite may require this.  In other words, the behavior exhibited
** when SQLite is compiled with [SQLITE_OMIT_AUTOINIT] might become the
** default behavior in some future release of SQLite.
**
** The sqlite3_os_init() routine does operating-system specific
** initialization of the SQLite library.  The sqlite3_os_end()
** routine undoes the effect of sqlite3_os_init().  Typical tasks
** performed by these routines include allocation or deallocation
** of static resources, initialization of global variables,
** setting up a default [sqlite3_vfs] module, or setting up
** a default configuration using [sqlite3_config()].
**
** The application should never invoke either sqlite3_os_init()
** or sqlite3_os_end() directly.  The application should only invoke
** sqlite3_initialize() and sqlite3_shutdown().  The sqlite3_os_init()
** interface is called automatically by sqlite3_initialize() and
** sqlite3_os_end() is called by sqlite3_shutdown().  Appropriate
** implementations for sqlite3_os_init() and sqlite3_os_end()
** are built into SQLite when it is compiled for Unix, Windows, or OS/2.
** When [custom builds | built for other platforms]
** (using the [SQLITE_OS_OTHER=1] compile-time
** option) the application must supply a suitable implementation for
** sqlite3_os_init() and sqlite3_os_end().  An application-supplied

** CAPI3REF: Memory Allocation Routines
**
** An instance of this object defines the interface between SQLite

** This object is used in only one place in the SQLite interface.
** A pointer to an instance of this object is the argument to
** [sqlite3_config()] when the configuration option is
** [SQLITE_CONFIG_MALLOC] or [SQLITE_CONFIG_GETMALLOC].  
** By creating an instance of this object
** and passing it to [sqlite3_config]([SQLITE_CONFIG_MALLOC])
** during configuration, an application can specify an alternative
** memory allocation subsystem for SQLite to use for all of its
** dynamic memory needs.
**
** Note that SQLite comes with several [built-in memory allocators]
** that are perfectly adequate for the overwhelming majority of applications
** and that this object is only useful to a tiny minority of applications
** with specialized memory allocation requirements.  This object is
** also used during testing of SQLite in order to specify an alternative
** memory allocator that simulates memory out-of-memory conditions in
** order to verify that SQLite recovers gracefully from such
** conditions.
**
** The xMalloc, xRealloc, and xFree methods must work like the
** malloc(), realloc() and free() functions from the standard C library.
** ^SQLite guarantees that the second argument to
** xRealloc is always a value returned by a prior call to xRoundup.
**
** xSize should return the allocated size of a memory allocation
** previously obtained from xMalloc or xRealloc.  The allocated size
** is always at least as big as the requested size but may be larger.
**
** The xRoundup method returns what would be the allocated size of
** a memory allocation given a particular requested size.  Most memory
** allocators round up memory allocations at least to the next multiple
** of 8.  Some allocators round up to a larger multiple or to a power of 2.
** Every memory allocation request coming in through [sqlite3_malloc()]
** or [sqlite3_realloc()] first calls xRoundup.  If xRoundup returns 0, 
** that causes the corresponding memory allocation to fail.
**
** The xInit method initializes the memory allocator.  (For example,
** it might allocate any require mutexes or initialize internal data
** structures.  The xShutdown method is invoked (indirectly) by
** [sqlite3_shutdown()] and should deallocate any resources acquired
** by xInit.  The pAppData pointer is used as the only parameter to
** xInit and xShutdown.
**
** SQLite holds the [SQLITE_MUTEX_STATIC_MASTER] mutex when it invokes
** the xInit method, so the xInit method need not be threadsafe.  The
** xShutdown method is only called from [sqlite3_shutdown()] so it does
** not need to be threadsafe either.  For all other methods, SQLite
** holds the [SQLITE_MUTEX_STATIC_MEM] mutex as long as the
** [SQLITE_CONFIG_MEMSTATUS] configuration option is turned on (which
** it is by default) and so the methods are automatically serialized.
** However, if [SQLITE_CONFIG_MEMSTATUS] is disabled, then the other
** methods must be threadsafe or else make their own arrangements for
** serialization.

** ^If the callback returns non-zero, then another attempt

** Consider a scenario where one process is holding a read lock that

** to promote to an exclusive lock.  The first process cannot proceed
** because it is blocked by the second and the second process cannot

** forces an automatic rollback of the changes.  See the
** <a href="/cvstrac/wiki?p=CorruptionFollowingBusyError">
** CorruptionFollowingBusyError</a> wiki page for a discussion of why
** this is important.
**

/*
** CAPI3REF: Convenience Routines For Running Queries
**
** This is a legacy interface that is preserved for backwards compatibility.
** Use of this interface is not recommended.
**
** Definition: A <b>result table</b> is memory data structure created by the
** [sqlite3_get_table()] interface.  A result table records the
** complete query results from one or more queries.
**
** The table conceptually has a number of rows and columns.  But
** these numbers are not part of the result table itself.  These
** numbers are obtained separately.  Let N be the number of rows
** and M be the number of columns.
**
** A result table is an array of pointers to zero-terminated UTF-8 strings.
** There are (N+1)*M elements in the array.  The first M pointers point
** to zero-terminated strings that  contain the names of the columns.
** The remaining entries all point to query results.  NULL values result
** in NULL pointers.  All other values are in their UTF-8 zero-terminated
** string representation as returned by [sqlite3_column_text()].
**
** A result table might consist of one or more memory allocations.
** It is not safe to pass a result table directly to [sqlite3_free()].
** A result table should be deallocated using [sqlite3_free_table()].
**
** ^(As an example of the result table format, suppose a query result
** is as follows:
**
** <blockquote><pre>
**        Name        | Age
**        -----------------------
**        Alice       | 43
**        Bob         | 28
**        Cindy       | 21
** </pre></blockquote>
**
** There are two column (M==2) and three rows (N==3).  Thus the
** result table has 8 entries.  Suppose the result table is stored
** in an array names azResult.  Then azResult holds this content:
**
** <blockquote><pre>
**        azResult&#91;0] = "Name";
**        azResult&#91;1] = "Age";
**        azResult&#91;2] = "Alice";
**        azResult&#91;3] = "43";
**        azResult&#91;4] = "Bob";
**        azResult&#91;5] = "28";
**        azResult&#91;6] = "Cindy";
**        azResult&#91;7] = "21";
** </pre></blockquote>)^
**
** ^The sqlite3_get_table() function evaluates one or more
** semicolon-separated SQL statements in the zero-terminated UTF-8
** string of its 2nd parameter and returns a result table to the
** pointer given in its 3rd parameter.
**
** After the application has finished with the result from sqlite3_get_table(),
** it must pass the result table pointer to sqlite3_free_table() in order to
** release the memory that was malloced.  Because of the way the
** [sqlite3_malloc()] happens within sqlite3_get_table(), the calling
** function must not try to call [sqlite3_free()] directly.  Only
** [sqlite3_free_table()] is able to release the memory properly and safely.
**
** The sqlite3_get_table() interface is implemented as a wrapper around
** [sqlite3_exec()].  The sqlite3_get_table() routine does not have access
** to any internal data structures of SQLite.  It uses only the public
** interface defined here.  As a consequence, errors that occur in the
** wrapper layer outside of the internal [sqlite3_exec()] call are not
** reflected in subsequent calls to [sqlite3_errcode()] or
** [sqlite3_errmsg()].

** CAPI3REF: Formatted String Printing Functions
**
** These routines are work-alikes of the "printf()" family of functions

** ^The sqlite3_mprintf() and sqlite3_vmprintf() routines write their
** results into memory obtained from [sqlite3_malloc()].
** The strings returned by these two routines should be
** released by [sqlite3_free()].  ^Both routines return a
** NULL pointer if [sqlite3_malloc()] is unable to allocate enough
** memory to hold the resulting string.
**
** ^(The sqlite3_snprintf() routine is similar to "snprintf()" from
** the standard C library.  The result is written into the
** buffer supplied as the second parameter whose size is given by
** the first parameter. Note that the order of the
** first two parameters is reversed from snprintf().)^  This is an
** historical accident that cannot be fixed without breaking
** backwards compatibility.  ^(Note also that sqlite3_snprintf()
** returns a pointer to its buffer instead of the number of
** characters actually written into the buffer.)^  We admit that
** the number of characters written would be a more useful return
** value but we cannot change the implementation of sqlite3_snprintf()
** now without breaking compatibility.
**
** ^As long as the buffer size is greater than zero, sqlite3_snprintf()
** guarantees that the buffer is always zero-terminated.  ^The first
** parameter "n" is the total size of the buffer, including space for
** the zero terminator.  So the longest string that can be completely
** written will be n-1 characters.
**
** ^The sqlite3_vsnprintf() routine is a varargs version of sqlite3_snprintf().
**
** These routines all implement some additional formatting
** options that are useful for constructing SQL statements.
** All of the usual printf() formatting options apply.  In addition, there
** is are "%q", "%Q", and "%z" options.
**
** ^(The %q option works like %s in that it substitutes a null-terminated
** string from the argument list.  But %q also doubles every '\'' character.
** %q is designed for use inside a string literal.)^  By doubling each '\''
** character it escapes that character and allows it to be inserted into
** the string.
**
** For example, assume the string variable zText contains text as follows:
**
** <blockquote><pre>
**  char *zText = "It's a happy day!";
** </pre></blockquote>
**
** One can use this text in an SQL statement as follows:
**
** <blockquote><pre>
**  char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES('%q')", zText);
**  sqlite3_exec(db, zSQL, 0, 0, 0);
**  sqlite3_free(zSQL);
** </pre></blockquote>
**
** Because the %q format string is used, the '\'' character in zText
** is escaped and the SQL generated is as follows:
**
** <blockquote><pre>
**  INSERT INTO table1 VALUES('It''s a happy day!')
** </pre></blockquote>
**
** This is correct.  Had we used %s instead of %q, the generated SQL
** would have looked like this:
**
** <blockquote><pre>
**  INSERT INTO table1 VALUES('It's a happy day!');
** </pre></blockquote>
**
** This second example is an SQL syntax error.  As a general rule you should
** always use %q instead of %s when inserting text into a string literal.
**
** ^(The %Q option works like %q except it also adds single quotes around
** the outside of the total string.  Additionally, if the parameter in the
** argument list is a NULL pointer, %Q substitutes the text "NULL" (without
** single quotes).)^  So, for example, one could say:
**
** <blockquote><pre>
**  char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES(%Q)", zText);
**  sqlite3_exec(db, zSQL, 0, 0, 0);
**  sqlite3_free(zSQL);
** </pre></blockquote>
**
** The code above will render a correct SQL statement in the zSQL
** variable even if the zText variable is a NULL pointer.
**
** ^(The "%z" formatting option works like "%s" but with the
** addition that after the string has been read and copied into
** the result, [sqlite3_free()] is called on the input string.)^

** Memory corruption, a segmentation fault, or other severe error
** might result if sqlite3_free() is called with a non-NULL pointer that
** was not obtained from sqlite3_malloc() or sqlite3_realloc().
**
** ^(The sqlite3_realloc() interface attempts to resize a

** ^If the second parameter to sqlite3_realloc() is zero or
** negative then the behavior is exactly the same as calling
** sqlite3_free(P) where P is the first parameter to sqlite3_realloc().
** ^sqlite3_realloc() returns a pointer to a memory allocation
** of at least N bytes in size or NULL if sufficient memory is unavailable.
** ^If M is the size of the prior allocation, then min(N,M) bytes

** ^If sqlite3_realloc() returns NULL, then the prior allocation

** return [SQLITE_OK] to allow the action, [SQLITE_IGNORE] to disallow the
** specific action but allow the SQL statement to continue to be
** compiled, or [SQLITE_DENY] to cause the entire SQL statement to be

** any value other than [SQLITE_IGNORE], [SQLITE_OK], or [SQLITE_DENY]
** then the [sqlite3_prepare_v2()] or equivalent call that triggered
** the authorizer will fail with an error message.
**
** When the callback returns [SQLITE_OK], that means the operation
** requested is ok.  ^When the callback returns [SQLITE_DENY], the
** [sqlite3_prepare_v2()] or equivalent call that triggered the
** authorizer will fail with an error message explaining that
** access is denied.

** to the callback is an integer [SQLITE_COPY | action code] that specifies
** the particular action to be authorized. ^The third through sixth parameters
** to the callback are zero-terminated strings that contain additional
** details about the action to be authorized.
**
** ^If the action code is [SQLITE_READ]
** and the callback returns [SQLITE_IGNORE] then the
** [prepared statement] statement is constructed to substitute
** a NULL value in place of the table column that would have
** been read if [SQLITE_OK] had been returned.  The [SQLITE_IGNORE]
** return can be used to deny an untrusted user access to individual
** columns of a table.
** ^If the action code is [SQLITE_DELETE] and the callback returns
** [SQLITE_IGNORE] then the [DELETE] operation proceeds but the
** [truncate optimization] is disabled and all rows are deleted individually.
**
** An authorizer is used when [sqlite3_prepare | preparing]
** SQL statements from an untrusted source, to ensure that the SQL statements
** do not try to access data they are not allowed to see, or that they do not
** try to execute malicious statements that damage the database.  For

** not want the user to be able to make arbitrary changes to the
** database.  An authorizer could then be put in place while the
** user-entered SQL is being [sqlite3_prepare | prepared] that
** disallows everything except [SELECT] statements.
**
** Applications that need to process SQL from untrusted sources
** might also consider lowering resource limits using [sqlite3_limit()]
** and limiting database size using the [max_page_count] [PRAGMA]
** in addition to using an authorizer.

/*
** CAPI3REF: Opening A New Database Connection
**
** ^These routines open an SQLite database file as specified by the 
** filename argument. ^The filename argument is interpreted as UTF-8 for
** sqlite3_open() and sqlite3_open_v2() and as UTF-16 in the native byte
** order for sqlite3_open16(). ^(A [database connection] handle is usually
** returned in *ppDb, even if an error occurs.  The only exception is that
** if SQLite is unable to allocate memory to hold the [sqlite3] object,
** a NULL will be written into *ppDb instead of a pointer to the [sqlite3]
** object.)^ ^(If the database is opened (and/or created) successfully, then
** [SQLITE_OK] is returned.  Otherwise an [error code] is returned.)^ ^The
** [sqlite3_errmsg()] or [sqlite3_errmsg16()] routines can be used to obtain
** an English language description of the error following a failure of any
** of the sqlite3_open() routines.
**
** ^The default encoding for the database will be UTF-8 if
** sqlite3_open() or sqlite3_open_v2() is called and
** UTF-16 in the native byte order if sqlite3_open16() is used.
**
** Whether or not an error occurs when it is opened, resources
** associated with the [database connection] handle should be released by
** passing it to [sqlite3_close()] when it is no longer required.
**
** The sqlite3_open_v2() interface works like sqlite3_open()
** except that it accepts two additional parameters for additional control
** over the new database connection.  ^(The flags parameter to
** sqlite3_open_v2() can take one of
** the following three values, optionally combined with the 
** [SQLITE_OPEN_NOMUTEX], [SQLITE_OPEN_FULLMUTEX], [SQLITE_OPEN_SHAREDCACHE],
** [SQLITE_OPEN_PRIVATECACHE], and/or [SQLITE_OPEN_URI] flags:)^

** already exist, an error is returned.</dd>)^
**
** ^(<dt>[SQLITE_OPEN_READWRITE]</dt>
** <dd>The database is opened for reading and writing if possible, or reading
** only if the file is write protected by the operating system.  In either
** case the database must already exist, otherwise an error is returned.</dd>)^
**
** ^(<dt>[SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE]</dt>
** <dd>The database is opened for reading and writing, and is created if
** it does not already exist. This is the behavior that is always used for
** sqlite3_open() and sqlite3_open16().</dd>)^
** </dl>
**
** If the 3rd parameter to sqlite3_open_v2() is not one of the
** combinations shown above optionally combined with other
** [SQLITE_OPEN_READONLY | SQLITE_OPEN_* bits]
** then the behavior is undefined.
**
** ^If the [SQLITE_OPEN_NOMUTEX] flag is set, then the database connection
** opens in the multi-thread [threading mode] as long as the single-thread
** mode has not been set at compile-time or start-time.  ^If the
** [SQLITE_OPEN_FULLMUTEX] flag is set then the database connection opens
** in the serialized [threading mode] unless single-thread was
** previously selected at compile-time or start-time.
** ^The [SQLITE_OPEN_SHAREDCACHE] flag causes the database connection to be
** eligible to use [shared cache mode], regardless of whether or not shared
** cache is enabled using [sqlite3_enable_shared_cache()].  ^The
** [SQLITE_OPEN_PRIVATECACHE] flag causes the database connection to not
** participate in [shared cache mode] even if it is enabled.
**
** ^The fourth parameter to sqlite3_open_v2() is the name of the
** [sqlite3_vfs] object that defines the operating system interface that
** the new database connection should use.  ^If the fourth parameter is
** a NULL pointer then the default [sqlite3_vfs] object is used.
**
** ^If the filename is ":memory:", then a private, temporary in-memory database
** is created for the connection.  ^This in-memory database will vanish when
** the database connection is closed.  Future versions of SQLite might
** make use of additional special filenames that begin with the ":" character.
** It is recommended that when a database filename actually does begin with
** a ":" character you should prefix the filename with a pathname such as
** "./" to avoid ambiguity.
**
** ^If the filename is an empty string, then a private, temporary
** on-disk database will be created.  ^This private database will be
** automatically deleted as soon as the database connection is closed.
**
** [[URI filenames in sqlite3_open()]] <h3>URI Filenames</h3>
**
** ^If [URI filename] interpretation is enabled, and the filename argument
** begins with "file:", then the filename is interpreted as a URI. ^URI
** filename interpretation is enabled if the [SQLITE_OPEN_URI] flag is
** set in the fourth argument to sqlite3_open_v2(), or if it has
** been enabled globally using the [SQLITE_CONFIG_URI] option with the
** [sqlite3_config()] method or by the [SQLITE_USE_URI] compile-time option.
** As of SQLite version 3.7.7, URI filename interpretation is turned off
** by default, but future releases of SQLite might enable URI filename
** interpretation by default.  See "[URI filenames]" for additional
** information.
**
** URI filenames are parsed according to RFC 3986. ^If the URI contains an
** authority, then it must be either an empty string or the string 
** "localhost". ^If the authority is not an empty string or "localhost", an 
** error is returned to the caller. ^The fragment component of a URI, if 
** present, is ignored.
**
** ^SQLite uses the path component of the URI as the name of the disk file
** which contains the database. ^If the path begins with a '/' character, 
** then it is interpreted as an absolute path. ^If the path does not begin 
** with a '/' (meaning that the authority section is omitted from the URI)
** then the path is interpreted as a relative path. 
** ^On windows, the first component of an absolute path 
** is a drive specification (e.g. "C:").
**
** [[core URI query parameters]]
** The query component of a URI may contain parameters that are interpreted
** either by SQLite itself, or by a [VFS | custom VFS implementation].
** SQLite interprets the following three query parameters:
**
** <ul>
**   <li> <b>vfs</b>: ^The "vfs" parameter may be used to specify the name of
**     a VFS object that provides the operating system interface that should
**     be used to access the database file on disk. ^If this option is set to
**     an empty string the default VFS object is used. ^Specifying an unknown
**     VFS is an error. ^If sqlite3_open_v2() is used and the vfs option is
**     present, then the VFS specified by the option takes precedence over
**     the value passed as the fourth parameter to sqlite3_open_v2().
**
**   <li> <b>mode</b>: ^(The mode parameter may be set to either "ro", "rw" or
**     "rwc". Attempting to set it to any other value is an error)^. 
**     ^If "ro" is specified, then the database is opened for read-only 
**     access, just as if the [SQLITE_OPEN_READONLY] flag had been set in the 
**     third argument to sqlite3_prepare_v2(). ^If the mode option is set to 
**     "rw", then the database is opened for read-write (but not create) 
**     access, as if SQLITE_OPEN_READWRITE (but not SQLITE_OPEN_CREATE) had 
**     been set. ^Value "rwc" is equivalent to setting both 
**     SQLITE_OPEN_READWRITE and SQLITE_OPEN_CREATE. ^If sqlite3_open_v2() is 
**     used, it is an error to specify a value for the mode parameter that is 
**     less restrictive than that specified by the flags passed as the third 
**     parameter.
**
**   <li> <b>cache</b>: ^The cache parameter may be set to either "shared" or
**     "private". ^Setting it to "shared" is equivalent to setting the
**     SQLITE_OPEN_SHAREDCACHE bit in the flags argument passed to
**     sqlite3_open_v2(). ^Setting the cache parameter to "private" is 
**     equivalent to setting the SQLITE_OPEN_PRIVATECACHE bit.
**     ^If sqlite3_open_v2() is used and the "cache" parameter is present in
**     a URI filename, its value overrides any behaviour requested by setting
**     SQLITE_OPEN_PRIVATECACHE or SQLITE_OPEN_SHAREDCACHE flag.
** </ul>
**
** ^Specifying an unknown parameter in the query component of a URI is not an
** error.  Future versions of SQLite might understand additional query
** parameters.  See "[query parameters with special meaning to SQLite]" for
** additional information.

** CAPI3REF: Compiling An SQL Statement
** KEYWORDS: {SQL statement compiler}
**
** To execute an SQL query, it must first be compiled into a byte-code
** program using one of these routines.
**
** The first argument, "db", is a [database connection] obtained from a
** prior successful call to [sqlite3_open()], [sqlite3_open_v2()] or
** [sqlite3_open16()].  The database connection must not have been closed.
**
** The second argument, "zSql", is the statement to be compiled, encoded
** as either UTF-8 or UTF-16.  The sqlite3_prepare() and sqlite3_prepare_v2()
** interfaces use UTF-8, and sqlite3_prepare16() and sqlite3_prepare16_v2()
** use UTF-16.
**
** ^If the nByte argument is less than zero, then zSql is read up to the
** first zero terminator. ^If nByte is non-negative, then it is the maximum
** number of  bytes read from zSql.  ^When nByte is non-negative, the
** zSql string ends at either the first '\000' or '\u0000' character or
** the nByte-th byte, whichever comes first. If the caller knows
** that the supplied string is nul-terminated, then there is a small
** performance advantage to be gained by passing an nByte parameter that
** is equal to the number of bytes in the input string <i>including</i>
** the nul-terminator bytes as this saves SQLite from having to
** make a copy of the input string.
**
** ^If pzTail is not NULL then *pzTail is made to point to the first byte
** past the end of the first SQL statement in zSql.  These routines only
** compile the first statement in zSql, so *pzTail is left pointing to
** what remains uncompiled.
**
** ^*ppStmt is left pointing to a compiled [prepared statement] that can be
** executed using [sqlite3_step()].  ^If there is an error, *ppStmt is set
** to NULL.  ^If the input text contains no SQL (if the input is an empty
** string or a comment) then *ppStmt is set to NULL.
** The calling procedure is responsible for deleting the compiled
** SQL statement using [sqlite3_finalize()] after it has finished with it.
** ppStmt may not be NULL.
**
** ^On success, the sqlite3_prepare() family of routines return [SQLITE_OK];
** otherwise an [error code] is returned.
**
** The sqlite3_prepare_v2() and sqlite3_prepare16_v2() interfaces are
** recommended for all new programs. The two older interfaces are retained
** for backwards compatibility, but their use is discouraged.
** ^In the "v2" interfaces, the prepared statement
** that is returned (the [sqlite3_stmt] object) contains a copy of the
** original SQL text. This causes the [sqlite3_step()] interface to
** behave differently in three ways:
**
** <ol>
** <li>
** ^If the database schema changes, instead of returning [SQLITE_SCHEMA] as it
** always used to do, [sqlite3_step()] will automatically recompile the SQL
** statement and try to run it again.
** </li>
**
** <li>
** ^When an error occurs, [sqlite3_step()] will return one of the detailed
** [error codes] or [extended error codes].  ^The legacy behavior was that
** [sqlite3_step()] would only return a generic [SQLITE_ERROR] result code
** and the application would have to make a second call to [sqlite3_reset()]
** in order to find the underlying cause of the problem. With the "v2" prepare
** interfaces, the underlying reason for the error is returned immediately.
** </li>
**
** <li>
** ^If the specific value bound to [parameter | host parameter] in the 
** WHERE clause might influence the choice of query plan for a statement,
** then the statement will be automatically recompiled, as if there had been 
** a schema change, on the first  [sqlite3_step()] call following any change
** to the [sqlite3_bind_text | bindings] of that [parameter]. 
** ^The specific value of WHERE-clause [parameter] might influence the 
** choice of query plan if the parameter is the left-hand side of a [LIKE]
** or [GLOB] operator or if the parameter is compared to an indexed column
** and the [SQLITE_ENABLE_STAT3] compile-time option is enabled.

** SQLite uses the sqlite3_value object to represent all values
** that can be stored in a database table. SQLite uses dynamic typing
** for the values it stores.  ^Values stored in sqlite3_value objects
** can be integers, floating point values, strings, BLOBs, or NULL.
**
** An sqlite3_value object may be either "protected" or "unprotected".
** Some interfaces require a protected sqlite3_value.  Other interfaces
** will accept either a protected or an unprotected sqlite3_value.
** Every interface that accepts sqlite3_value arguments specifies
** whether or not it requires a protected sqlite3_value.
**
** The terms "protected" and "unprotected" refer to whether or not
** a mutex is held.  An internal mutex is held for a protected
** sqlite3_value object but no mutex is held for an unprotected
** sqlite3_value object.  If SQLite is compiled to be single-threaded
** (with [SQLITE_THREADSAFE=0] and with [sqlite3_threadsafe()] returning 0)
** or if SQLite is run in one of reduced mutex modes 
** [SQLITE_CONFIG_SINGLETHREAD] or [SQLITE_CONFIG_MULTITHREAD]
** then there is no distinction between protected and unprotected
** sqlite3_value objects and they can be used interchangeably.  However,
** for maximum code portability it is recommended that applications
** still make the distinction between protected and unprotected
** sqlite3_value objects even when not strictly required.
**
** ^The sqlite3_value objects that are passed as parameters into the
** implementation of [application-defined SQL functions] are protected.
** ^The sqlite3_value object returned by

** can be set using the sqlite3_bind_*() routines defined here.
**
** ^The first argument to the sqlite3_bind_*() routines is always
** a pointer to the [sqlite3_stmt] object returned from
** [sqlite3_prepare_v2()] or its variants.
**
** ^The second argument is the index of the SQL parameter to be set.
** ^The leftmost SQL parameter has an index of 1.  ^When the same named
** SQL parameter is used more than once, second and subsequent
** occurrences have the same index as the first occurrence.
** ^The index for named parameters can be looked up using the
** [sqlite3_bind_parameter_index()] API if desired.  ^The index
** for "?NNN" parameters is the value of NNN.
** ^The NNN value must be between 1 and the [sqlite3_limit()]
** parameter [SQLITE_LIMIT_VARIABLE_NUMBER] (default value: 999).
**
** ^The third argument is the value to bind to the parameter.
**
** ^(In those routines that have a fourth argument, its value is the
** number of bytes in the parameter.  To be clear: the value is the
** number of <u>bytes</u> in the value, not the number of characters.)^
** ^If the fourth parameter is negative, the length of the string is
** the number of bytes up to the first zero terminator.
** If a non-negative fourth parameter is provided to sqlite3_bind_text()
** or sqlite3_bind_text16() then that parameter must be the byte offset
** where the NUL terminator would occur assuming the string were NUL
** terminated.  If any NUL characters occur at byte offsets less than 
** the value of the fourth parameter then the resulting string value will
** contain embedded NULs.  The result of expressions involving strings
** with embedded NULs is undefined.
**
** ^The fifth argument to sqlite3_bind_blob(), sqlite3_bind_text(), and
** sqlite3_bind_text16() is a destructor used to dispose of the BLOB or
** string after SQLite has finished with it.  ^The destructor is called
** to dispose of the BLOB or string even if the call to sqlite3_bind_blob(),
** sqlite3_bind_text(), or sqlite3_bind_text16() fails.  
** ^If the fifth argument is
** the special value [SQLITE_STATIC], then SQLite assumes that the
** information is in static, unmanaged space and does not need to be freed.
** ^If the fifth argument has the value [SQLITE_TRANSIENT], then
** SQLite makes its own private copy of the data immediately, before
** the sqlite3_bind_*() routine returns.
**
** ^The sqlite3_bind_zeroblob() routine binds a BLOB of length N that
** is filled with zeroes.  ^A zeroblob uses a fixed amount of memory
** (just an integer to hold its size) while it is being processed.
** Zeroblobs are intended to serve as placeholders for BLOBs whose
** content is later written using
** [sqlite3_blob_open | incremental BLOB I/O] routines.
** ^A negative value for the zeroblob results in a zero-length BLOB.
**
** ^If any of the sqlite3_bind_*() routines are called with a NULL pointer
** for the [prepared statement] or with a prepared statement for which

**
** The details of the behavior of the sqlite3_step() interface depend
** on whether the statement was prepared using the newer "v2" interface
** [sqlite3_prepare_v2()] and [sqlite3_prepare16_v2()] or the older legacy
** interface [sqlite3_prepare()] and [sqlite3_prepare16()].  The use of the
** new "v2" interface is recommended for new applications but the legacy
** interface will continue to be supported.
**
** ^In the legacy interface, the return value will be either [SQLITE_BUSY],
** [SQLITE_DONE], [SQLITE_ROW], [SQLITE_ERROR], or [SQLITE_MISUSE].
** ^With the "v2" interface, any of the other [result codes] or
** [extended result codes] might be returned as well.
**
** ^[SQLITE_BUSY] means that the database engine was unable to acquire the
** database locks it needs to do its job.  ^If the statement is a [COMMIT]
** or occurs outside of an explicit transaction, then you can retry the
** statement.  If the statement is not a [COMMIT] and occurs within an
** explicit transaction then you should rollback the transaction before
** continuing.
**
** ^[SQLITE_DONE] means that the statement has finished executing
** successfully.  sqlite3_step() should not be called again on this virtual
** machine without first calling [sqlite3_reset()] to reset the virtual
** machine back to its initial state.
**
** ^If the SQL statement being executed returns any data, then [SQLITE_ROW]
** is returned each time a new row of data is ready for processing by the
** caller. The values may be accessed using the [column access functions].
** sqlite3_step() is called again to retrieve the next row of data.
**
** ^[SQLITE_ERROR] means that a run-time error (such as a constraint
** violation) has occurred.  sqlite3_step() should not be called again on
** the VM. More information may be found by calling [sqlite3_errmsg()].
** ^With the legacy interface, a more specific error code (for example,
** [SQLITE_INTERRUPT], [SQLITE_SCHEMA], [SQLITE_CORRUPT], and so forth)
** can be obtained by calling [sqlite3_reset()] on the
** [prepared statement].  ^In the "v2" interface,
** the more specific error code is returned directly by sqlite3_step().
**
** [SQLITE_MISUSE] means that the this routine was called inappropriately.
** Perhaps it was called on a [prepared statement] that has
** already been [sqlite3_finalize | finalized] or on one that had
** previously returned [SQLITE_ERROR] or [SQLITE_DONE].  Or it could
** be the case that the same database connection is being used by two or
** more threads at the same moment in time.
**
** For all versions of SQLite up to and including 3.6.23.1, a call to
** [sqlite3_reset()] was required after sqlite3_step() returned anything
** other than [SQLITE_ROW] before any subsequent invocation of
** sqlite3_step().  Failure to reset the prepared statement using 
** [sqlite3_reset()] would result in an [SQLITE_MISUSE] return from
** sqlite3_step().  But after version 3.6.23.1, sqlite3_step() began
** calling [sqlite3_reset()] automatically in this circumstance rather
** than returning [SQLITE_MISUSE].  This is not considered a compatibility
** break because any application that ever receives an SQLITE_MISUSE error
** is broken by definition.  The [SQLITE_OMIT_AUTORESET] compile-time option
** can be used to restore the legacy behavior.
**
** <b>Goofy Interface Alert:</b> In the legacy interface, the sqlite3_step()
** API always returns a generic error code, [SQLITE_ERROR], following any
** error other than [SQLITE_BUSY] and [SQLITE_MISUSE].  You must call
** [sqlite3_reset()] or [sqlite3_finalize()] in order to find one of the
** specific [error codes] that better describes the error.
** We admit that this is a goofy design.  The problem has been fixed
** with the "v2" interface.  If you prepare all of your SQL statements
** using either [sqlite3_prepare_v2()] or [sqlite3_prepare16_v2()] instead
** of the legacy [sqlite3_prepare()] and [sqlite3_prepare16()] interfaces,
** then the more specific [error codes] are returned directly

** </blockquote>)^
**
** The table above makes reference to standard C library functions atoi()
** and atof().  SQLite does not really use these functions.  It has its
** own equivalent internal routines.  The atoi() and atof() names are
** used in the table for brevity and because they are familiar to most
** C programmers.
**
** Note that when type conversions occur, pointers returned by prior
** calls to sqlite3_column_blob(), sqlite3_column_text(), and/or
** sqlite3_column_text16() may be invalidated.
** Type conversions and pointer invalidations might occur
** in the following cases:
**
** <ul>
** <li> The initial content is a BLOB and sqlite3_column_text() or
**      sqlite3_column_text16() is called.  A zero-terminator might
**      need to be added to the string.</li>
** <li> The initial content is UTF-8 text and sqlite3_column_bytes16() or
**      sqlite3_column_text16() is called.  The content must be converted
**      to UTF-16.</li>
** <li> The initial content is UTF-16 text and sqlite3_column_bytes() or
**      sqlite3_column_text() is called.  The content must be converted
**      to UTF-8.</li>
** </ul>
**
** ^Conversions between UTF-16be and UTF-16le are always done in place and do
** not invalidate a prior pointer, though of course the content of the buffer
** that the prior pointer references will have been modified.  Other kinds
** of conversion are done in place when it is possible, but sometimes they
** are not possible and in those cases prior pointers are invalidated.
**
** The safest and easiest to remember policy is to invoke these routines
** in one of the following ways:
**
** <ul>
**  <li>sqlite3_column_text() followed by sqlite3_column_bytes()</li>
**  <li>sqlite3_column_blob() followed by sqlite3_column_bytes()</li>
**  <li>sqlite3_column_text16() followed by sqlite3_column_bytes16()</li>
** </ul>
**
** In other words, you should call sqlite3_column_text(),
** sqlite3_column_blob(), or sqlite3_column_text16() first to force the result
** into the desired format, then invoke sqlite3_column_bytes() or
** sqlite3_column_bytes16() to find the size of the result.  Do not mix calls
** to sqlite3_column_text() or sqlite3_column_blob() with calls to
** sqlite3_column_bytes16(), and do not mix calls to sqlite3_column_text16()
** with calls to sqlite3_column_bytes().
**
** ^The pointers returned are valid until a type conversion occurs as
** described above, or until [sqlite3_step()] or [sqlite3_reset()] or
** [sqlite3_finalize()] is called.  ^The memory space used to hold strings
** and BLOBs is freed automatically.  Do <b>not</b> pass the pointers returned
** [sqlite3_column_blob()], [sqlite3_column_text()], etc. into
** [sqlite3_free()].
**
** ^(If a memory allocation error occurs during the evaluation of any
** of these routines, a default value is returned.  The default value
** is either the integer 0, the floating point number 0.0, or a NULL
** pointer.  Subsequent calls to [sqlite3_errcode()] will return
** [SQLITE_NOMEM].)^

**
** ^These functions (collectively known as "function creation routines")
** are used to add SQL functions or aggregates or to redefine the behavior
** of existing SQL functions or aggregates.  The only differences between
** these routines are the text encoding expected for
** the second parameter (the name of the function being created)
** and the presence or absence of a destructor callback for
** the application data pointer.
**
** ^The first parameter is the [database connection] to which the SQL
** function is to be added.  ^If an application uses more than one database
** connection then application-defined SQL functions must be added
** to each database connection separately.
**
** ^The second parameter is the name of the SQL function to be created or
** redefined.  ^The length of the name is limited to 255 bytes in a UTF-8
** representation, exclusive of the zero-terminator.  ^Note that the name
** length limit is in UTF-8 bytes, not characters nor UTF-16 bytes.  
** ^Any attempt to create a function with a longer name
** will result in [SQLITE_MISUSE] being returned.
**
** ^The third parameter (nArg)
** is the number of arguments that the SQL function or
** aggregate takes. ^If this parameter is -1, then the SQL function or
** aggregate may take any number of arguments between 0 and the limit
** set by [sqlite3_limit]([SQLITE_LIMIT_FUNCTION_ARG]).  If the third
** parameter is less than -1 or greater than 127 then the behavior is
** undefined.
**
** ^The fourth parameter, eTextRep, specifies what
** [SQLITE_UTF8 | text encoding] this SQL function prefers for
** its parameters.  Every SQL function implementation must be able to work
** with UTF-8, UTF-16le, or UTF-16be.  But some implementations may be
** more efficient with one encoding than another.  ^An application may
** invoke sqlite3_create_function() or sqlite3_create_function16() multiple
** times with the same function but with different values of eTextRep.
** ^When multiple implementations of the same function are available, SQLite
** will pick the one that involves the least amount of data conversion.
** If there is only a single implementation which does not care what text
** encoding is used, then the fourth argument should be [SQLITE_ANY].
**
** ^(The fifth parameter is an arbitrary pointer.  The implementation of the
** function can gain access to this pointer using [sqlite3_user_data()].)^
**
** ^The sixth, seventh and eighth parameters, xFunc, xStep and xFinal, are
** pointers to C-language functions that implement the SQL function or
** aggregate. ^A scalar SQL function requires an implementation of the xFunc
** callback only; NULL pointers must be passed as the xStep and xFinal
** parameters. ^An aggregate SQL function requires an implementation of xStep
** and xFinal and NULL pointer must be passed for xFunc. ^To delete an existing
** SQL function or aggregate, pass NULL pointers for all three function
** callbacks.
**
** ^(If the ninth parameter to sqlite3_create_function_v2() is not NULL,
** then it is destructor for the application data pointer. 
** The destructor is invoked when the function is deleted, either by being
** overloaded or when the database connection closes.)^
** ^The destructor is also invoked if the call to
** sqlite3_create_function_v2() fails.
** ^When the destructor callback of the tenth parameter is invoked, it
** is passed a single argument which is a copy of the application data 
** pointer which was the fifth parameter to sqlite3_create_function_v2().
**
** ^It is permitted to register multiple implementations of the same
** functions with the same name but with either differing numbers of
** arguments or differing preferred text encodings.  ^SQLite will use
** the implementation that most closely matches the way in which the
** SQL function is used.  ^A function implementation with a non-negative
** nArg parameter is a better match than a function implementation with
** a negative nArg.  ^A function where the preferred text encoding
** matches the database encoding is a better
** match than a function where the encoding is different.  
** ^A function where the encoding difference is between UTF16le and UTF16be
** is a closer match than a function where the encoding difference is
** between UTF8 and UTF16.
**
** ^Built-in functions may be overloaded by new application-defined functions.
**
** ^An application-defined function is permitted to call other
** SQLite interfaces.  However, such calls must not
** close the database connection nor finalize or reset the prepared
** statement in which the function is running.

**
** ^The name of the collation is a UTF-8 string
** for sqlite3_create_collation() and sqlite3_create_collation_v2()
** and a UTF-16 string in native byte order for sqlite3_create_collation16().
** ^Collation names that compare equal according to [sqlite3_strnicmp()] are
** considered to be the same name.
**
** ^(The third argument (eTextRep) must be one of the constants:
** <ul>
** <li> [SQLITE_UTF8],
** <li> [SQLITE_UTF16LE],
** <li> [SQLITE_UTF16BE],
** <li> [SQLITE_UTF16], or
** <li> [SQLITE_UTF16_ALIGNED].
** </ul>)^
** ^The eTextRep argument determines the encoding of strings passed
** to the collating function callback, xCallback.
** ^The [SQLITE_UTF16] and [SQLITE_UTF16_ALIGNED] values for eTextRep
** force strings to be UTF16 with native byte order.
** ^The [SQLITE_UTF16_ALIGNED] value for eTextRep forces strings to begin
** on an even byte address.
**
** ^The fourth argument, pArg, is an application data pointer that is passed
** through as the first argument to the collating function callback.
**
** ^The fifth argument, xCallback, is a pointer to the collating function.
** ^Multiple collating functions can be registered using the same name but
** with different eTextRep parameters and SQLite will use whichever
** function requires the least amount of data transformation.
** ^If the xCallback argument is NULL then the collating function is
** deleted.  ^When all collating functions having the same name are deleted,
** that collation is no longer usable.
**
** ^The collating function callback is invoked with a copy of the pArg 
** application data pointer and with two strings in the encoding specified
** by the eTextRep argument.  The collating function must return an
** integer that is negative, zero, or positive
** if the first string is less than, equal to, or greater than the second,
** respectively.  A collating function must always return the same answer
** given the same inputs.  If two or more collating functions are registered
** to the same collation name (using different eTextRep values) then all
** must give an equivalent answer when invoked with equivalent strings.
** The collating function must obey the following properties for all
** strings A, B, and C:
**
** <ol>
** <li> If A==B then B==A.
** <li> If A==B and B==C then A==C.
** <li> If A&lt;B THEN B&gt;A.
** <li> If A&lt;B and B&lt;C then A&lt;C.
** </ol>
**
** If a collating function fails any of the above constraints and that
** collating function is  registered and used, then the behavior of SQLite
** is undefined.
**
** ^The sqlite3_create_collation_v2() works like sqlite3_create_collation()
** with the addition that the xDestroy callback is invoked on pArg when
** the collating function is deleted.
** ^Collating functions are deleted when they are overridden by later
** calls to the collation creation functions or when the
** [database connection] is closed using [sqlite3_close()].
**
** ^The xDestroy callback is <u>not</u> called if the 
** sqlite3_create_collation_v2() function fails.  Applications that invoke
** sqlite3_create_collation_v2() with a non-NULL xDestroy argument should 
** check the return code and dispose of the application data pointer

** This is different from every other SQLite interface.  The inconsistency 
** is unfortunate but cannot be changed without breaking backwards 
** compatibility.

** CAPI3REF: Mutexes
**
** The SQLite core uses these routines for thread
** synchronization. Though they are intended for internal
** use by SQLite, code that links against SQLite is
** permitted to use any of these routines.
**
** The SQLite source code contains multiple implementations
** of these mutex routines.  An appropriate implementation
** is selected automatically at compile-time.  ^(The following
** implementations are available in the SQLite core:
**
** <ul>
** <li>   SQLITE_MUTEX_OS2
** <li>   SQLITE_MUTEX_PTHREAD
** <li>   SQLITE_MUTEX_W32
** <li>   SQLITE_MUTEX_NOOP
** </ul>)^
**
** ^The SQLITE_MUTEX_NOOP implementation is a set of routines
** that does no real locking and is appropriate for use in
** a single-threaded application.  ^The SQLITE_MUTEX_OS2,
** SQLITE_MUTEX_PTHREAD, and SQLITE_MUTEX_W32 implementations
** are appropriate for use on OS/2, Unix, and Windows.
**
** ^(If SQLite is compiled with the SQLITE_MUTEX_APPDEF preprocessor
** macro defined (with "-DSQLITE_MUTEX_APPDEF=1"), then no mutex
** implementation is included with the library. In this case the
** application must supply a custom mutex implementation using the
** [SQLITE_CONFIG_MUTEX] option of the sqlite3_config() function
** before calling sqlite3_initialize() or any other public sqlite3_
** function that calls sqlite3_initialize().)^
**
** ^The sqlite3_mutex_alloc() routine allocates a new
** mutex and returns a pointer to it. ^If it returns NULL
** that means that a mutex could not be allocated.  ^SQLite
** will unwind its stack and return an error.  ^(The argument
** to sqlite3_mutex_alloc() is one of these integer constants:
**
** <ul>
** <li>  SQLITE_MUTEX_FAST
** <li>  SQLITE_MUTEX_RECURSIVE
** <li>  SQLITE_MUTEX_STATIC_MASTER
** <li>  SQLITE_MUTEX_STATIC_MEM
** <li>  SQLITE_MUTEX_STATIC_MEM2
** <li>  SQLITE_MUTEX_STATIC_PRNG
** <li>  SQLITE_MUTEX_STATIC_LRU
** <li>  SQLITE_MUTEX_STATIC_LRU2
** </ul>)^
**
** ^The first two constants (SQLITE_MUTEX_FAST and SQLITE_MUTEX_RECURSIVE)
** cause sqlite3_mutex_alloc() to create
** a new mutex.  ^The new mutex is recursive when SQLITE_MUTEX_RECURSIVE
** is used but not necessarily so when SQLITE_MUTEX_FAST is used.
** The mutex implementation does not need to make a distinction
** between SQLITE_MUTEX_RECURSIVE and SQLITE_MUTEX_FAST if it does
** not want to.  ^SQLite will only request a recursive mutex in
** cases where it really needs one.  ^If a faster non-recursive mutex
** implementation is available on the host platform, the mutex subsystem
** might return such a mutex in response to SQLITE_MUTEX_FAST.
**
** ^The other allowed parameters to sqlite3_mutex_alloc() (anything other
** than SQLITE_MUTEX_FAST and SQLITE_MUTEX_RECURSIVE) each return
** a pointer to a static preexisting mutex.  ^Six static mutexes are
** used by the current version of SQLite.  Future versions of SQLite
** may add additional static mutexes.  Static mutexes are for internal
** use by SQLite only.  Applications that use SQLite mutexes should
** use only the dynamic mutexes returned by SQLITE_MUTEX_FAST or
** SQLITE_MUTEX_RECURSIVE.
**
** ^Note that if one of the dynamic mutex parameters (SQLITE_MUTEX_FAST
** or SQLITE_MUTEX_RECURSIVE) is used then sqlite3_mutex_alloc()
** returns a different mutex on every call.  ^But for the static
** mutex types, the same mutex is returned on every call that has
** the same type number.
**
** ^The sqlite3_mutex_free() routine deallocates a previously
** allocated dynamic mutex.  ^SQLite is careful to deallocate every
** dynamic mutex that it allocates.  The dynamic mutexes must not be in
** use when they are deallocated.  Attempting to deallocate a static
** mutex results in undefined behavior.  ^SQLite never deallocates
** a static mutex.
**
** ^The sqlite3_mutex_enter() and sqlite3_mutex_try() routines attempt
** to enter a mutex.  ^If another thread is already within the mutex,
** sqlite3_mutex_enter() will block and sqlite3_mutex_try() will return
** SQLITE_BUSY.  ^The sqlite3_mutex_try() interface returns [SQLITE_OK]
** upon successful entry.  ^(Mutexes created using
** SQLITE_MUTEX_RECURSIVE can be entered multiple times by the same thread.
** In such cases the,
** mutex must be exited an equal number of times before another thread
** can enter.)^  ^(If the same thread tries to enter any other
** kind of mutex more than once, the behavior is undefined.
** SQLite will never exhibit
** such behavior in its own use of mutexes.)^
**
** ^(Some systems (for example, Windows 95) do not support the operation
** implemented by sqlite3_mutex_try().  On those systems, sqlite3_mutex_try()
** will always return SQLITE_BUSY.  The SQLite core only ever uses
** sqlite3_mutex_try() as an optimization so this is acceptable behavior.)^
**
** ^The sqlite3_mutex_leave() routine exits a mutex that was
** previously entered by the same thread.   ^(The behavior
** is undefined if the mutex is not currently entered by the
** calling thread or is not currently allocated.  SQLite will
** never do either.)^
**
** ^If the argument to sqlite3_mutex_enter(), sqlite3_mutex_try(), or
** sqlite3_mutex_leave() is a NULL pointer, then all three routines
** behave as no-ops.

** CAPI3REF: Mutex Methods Object
**
** An instance of this structure defines the low-level routines
** used to allocate and use mutexes.
**
** Usually, the default mutex implementations provided by SQLite are
** sufficient, however the user has the option of substituting a custom
** implementation for specialized deployments or systems for which SQLite
** does not provide a suitable implementation. In this case, the user
** creates and populates an instance of this structure to pass
** to sqlite3_config() along with the [SQLITE_CONFIG_MUTEX] option.
** Additionally, an instance of this structure can be used as an
** output variable when querying the system for the current mutex
** implementation, using the [SQLITE_CONFIG_GETMUTEX] option.
**
** ^The xMutexInit method defined by this structure is invoked as
** part of system initialization by the sqlite3_initialize() function.
** ^The xMutexInit routine is called by SQLite exactly once for each
** effective call to [sqlite3_initialize()].
**
** ^The xMutexEnd method defined by this structure is invoked as
** part of system shutdown by the sqlite3_shutdown() function. The
** implementation of this method is expected to release all outstanding
** resources obtained by the mutex methods implementation, especially
** those obtained by the xMutexInit method.  ^The xMutexEnd()
** interface is invoked exactly once for each call to [sqlite3_shutdown()].
**
** ^(The remaining seven methods defined by this structure (xMutexAlloc,
** xMutexFree, xMutexEnter, xMutexTry, xMutexLeave, xMutexHeld and
** xMutexNotheld) implement the following interfaces (respectively):
**
** <ul>
**   <li>  [sqlite3_mutex_alloc()] </li>
**   <li>  [sqlite3_mutex_free()] </li>
**   <li>  [sqlite3_mutex_enter()] </li>
**   <li>  [sqlite3_mutex_try()] </li>
**   <li>  [sqlite3_mutex_leave()] </li>
**   <li>  [sqlite3_mutex_held()] </li>
**   <li>  [sqlite3_mutex_notheld()] </li>
** </ul>)^
**
** The only difference is that the public sqlite3_XXX functions enumerated
** above silently ignore any invocations that pass a NULL pointer instead
** of a valid mutex handle. The implementations of the methods defined
** by this structure are not required to handle this case, the results
** of passing a NULL pointer instead of a valid mutex handle are undefined
** (i.e. it is acceptable to provide an implementation that segfaults if
** it is passed a NULL pointer).
**
** The xMutexInit() method must be threadsafe.  ^It must be harmless to
** invoke xMutexInit() multiple times within the same process and without
** intervening calls to xMutexEnd().  Second and subsequent calls to
** xMutexInit() must be no-ops.
**
** ^xMutexInit() must not use SQLite memory allocation ([sqlite3_malloc()]
** and its associates).  ^Similarly, xMutexAlloc() must not use SQLite memory
** allocation for a static mutex.  ^However xMutexAlloc() may use SQLite
** memory allocation for a fast or recursive mutex.
**
** ^SQLite will invoke the xMutexEnd() method when [sqlite3_shutdown()] is
** called, but only if the prior call to xMutexInit returned SQLITE_OK.
** If xMutexInit fails in any way, it is expected to clean up after itself
** prior to returning.

** CAPI3REF: Application Defined Page Cache.
** KEYWORDS: {page cache}
**
** ^(The [sqlite3_config]([SQLITE_CONFIG_PCACHE], ...) interface can
** register an alternative page cache implementation by passing in an 
** instance of the sqlite3_pcache_methods structure.)^
** In many applications, most of the heap memory allocated by 
** SQLite is used for the page cache.
** By implementing a 
** custom page cache using this API, an application can better control
** the amount of memory consumed by SQLite, the way in which 
** that memory is allocated and released, and the policies used to 
** determine exactly which parts of a database file are cached and for 
** how long.
**
** The alternative page cache mechanism is an
** extreme measure that is only needed by the most demanding applications.
** The built-in page cache is recommended for most uses.
**
** ^(The contents of the sqlite3_pcache_methods structure are copied to an
** internal buffer by SQLite within the call to [sqlite3_config].  Hence
** the application may discard the parameter after the call to
** [sqlite3_config()] returns.)^
**
** [[the xInit() page cache method]]
** ^(The xInit() method is called once for each effective 
** call to [sqlite3_initialize()])^
** (usually only once during the lifetime of the process). ^(The xInit()
** method is passed a copy of the sqlite3_pcache_methods.pArg value.)^
** The intent of the xInit() method is to set up global data structures 
** required by the custom page cache implementation. 
** ^(If the xInit() method is NULL, then the 
** built-in default page cache is used instead of the application defined
** page cache.)^
**
** [[the xShutdown() page cache method]]
** ^The xShutdown() method is called by [sqlite3_shutdown()].
** It can be used to clean up 
** any outstanding resources before process shutdown, if required.
** ^The xShutdown() method may be NULL.
**
** ^SQLite automatically serializes calls to the xInit method,
** so the xInit method need not be threadsafe.  ^The
** xShutdown method is only called from [sqlite3_shutdown()] so it does
** not need to be threadsafe either.  All other methods must be threadsafe
** in multithreaded applications.
**
** ^SQLite will never invoke xInit() more than once without an intervening
** call to xShutdown().
**
** [[the xCreate() page cache methods]]
** ^SQLite invokes the xCreate() method to construct a new cache instance.
** SQLite will typically create one cache instance for each open database file,
** though this is not guaranteed. ^The
** first parameter, szPage, is the size in bytes of the pages that must
** be allocated by the cache.  ^szPage will not be a power of two.  ^szPage
** will the page size of the database file that is to be cached plus an
** increment (here called "R") of less than 250.  SQLite will use the
** extra R bytes on each page to store metadata about the underlying
** database page on disk.  The value of R depends
** on the SQLite version, the target platform, and how SQLite was compiled.
** ^(R is constant for a particular build of SQLite. Except, there are two
** distinct values of R when SQLite is compiled with the proprietary
** ZIPVFS extension.)^  ^The second argument to
** xCreate(), bPurgeable, is true if the cache being created will
** be used to cache database pages of a file stored on disk, or
** false if it is used for an in-memory database. The cache implementation
** does not have to do anything special based with the value of bPurgeable;
** it is purely advisory.  ^On a cache where bPurgeable is false, SQLite will
** never invoke xUnpin() except to deliberately delete a page.
** ^In other words, calls to xUnpin() on a cache with bPurgeable set to
** false will always have the "discard" flag set to true.  
** ^Hence, a cache created with bPurgeable false will
** never contain any unpinned pages.
**
** [[the xCachesize() page cache method]]
** ^(The xCachesize() method may be called at any time by SQLite to set the
** suggested maximum cache-size (number of pages stored by) the cache
** instance passed as the first argument. This is the value configured using
** the SQLite "[PRAGMA cache_size]" command.)^  As with the bPurgeable
** parameter, the implementation is not required to do anything with this
** value; it is advisory only.
**
** [[the xPagecount() page cache methods]]
** The xPagecount() method must return the number of pages currently
** stored in the cache, both pinned and unpinned.
** 
** [[the xFetch() page cache methods]]
** The xFetch() method locates a page in the cache and returns a pointer to 
** the page, or a NULL pointer.
** A "page", in this context, means a buffer of szPage bytes aligned at an
** 8-byte boundary. The page to be fetched is determined by the key. ^The
** minimum key value is 1.  After it has been retrieved using xFetch, the page 
** is considered to be "pinned".
**
** If the requested page is already in the page cache, then the page cache
** implementation must return a pointer to the page buffer with its content
** intact.  If the requested page is not already in the cache, then the
** cache implementation should use the value of the createFlag
** parameter to help it determined what action to take:
**
** <table border=1 width=85% align=center>
** <tr><th> createFlag <th> Behaviour when page is not already in cache
** <tr><td> 0 <td> Do not allocate a new page.  Return NULL.
** <tr><td> 1 <td> Allocate a new page if it easy and convenient to do so.
**                 Otherwise return NULL.
** <tr><td> 2 <td> Make every effort to allocate a new page.  Only return
**                 NULL if allocating a new page is effectively impossible.
** </table>
**
** ^(SQLite will normally invoke xFetch() with a createFlag of 0 or 1.  SQLite
** will only use a createFlag of 2 after a prior call with a createFlag of 1
** failed.)^  In between the to xFetch() calls, SQLite may
** attempt to unpin one or more cache pages by spilling the content of
** pinned pages to disk and synching the operating system disk cache.
**
** [[the xUnpin() page cache method]]
** ^xUnpin() is called by SQLite with a pointer to a currently pinned page
** as its second argument.  If the third parameter, discard, is non-zero,
** then the page must be evicted from the cache.
** ^If the discard parameter is
** zero, then the page may be discarded or retained at the discretion of
** page cache implementation. ^The page cache implementation
** may choose to evict unpinned pages at any time.
**
** The cache must not perform any reference counting. A single 
** call to xUnpin() unpins the page regardless of the number of prior calls 
** to xFetch().
**
** [[the xRekey() page cache methods]]
** The xRekey() method is used to change the key value associated with the
** page passed as the second argument. If the cache
** previously contains an entry associated with newKey, it must be
** discarded. ^Any prior cache entry associated with newKey is guaranteed not
** to be pinned.
**
** When SQLite calls the xTruncate() method, the cache must discard all
** existing cache entries with page numbers (keys) greater than or equal
** to the value of the iLimit parameter passed to xTruncate(). If any
** of these pages are pinned, they are implicitly unpinned, meaning that
** they can be safely discarded.
**
** [[the xDestroy() page cache method]]
** ^The xDestroy() method is used to delete a cache allocated by xCreate().
** All resources associated with the specified cache should be freed. ^After
** calling the xDestroy() method, SQLite considers the [sqlite3_pcache*]
** handle invalid, and will not use it with any other sqlite3_pcache_methods
** functions.

** <b>Concurrent Usage of Database Handles</b>

** if the application incorrectly accesses the destination [database connection]
** and so no error code is reported, but the operations may malfunction
** nevertheless.  Use of the destination database connection while a
** backup is in progress might also also cause a mutex deadlock.
**
** If running in [shared cache mode], the application must
** guarantee that the shared cache used by the destination database
** is not accessed while the backup is running. In practice this means
** that the application must guarantee that the disk file being 
** backed up to is not accessed by any connection within the process,
** not just the specific connection that was passed to sqlite3_backup_init().
**
** The [sqlite3_backup] object itself is partially threadsafe. Multiple 
** threads may safely make multiple concurrent calls to sqlite3_backup_step().
** However, the sqlite3_backup_remaining() and sqlite3_backup_pagecount()
** APIs are not strictly speaking threadsafe. If they are invoked at the
** same time as another thread is invoking sqlite3_backup_step() it is
** possible that they return invalid values.

** CAPI3REF: Unlock Notification
**
** ^When running in shared-cache mode, a database operation may fail with
** an [SQLITE_LOCKED] error if the required locks on the shared-cache or
** individual tables within the shared-cache cannot be obtained. See
** [SQLite Shared-Cache Mode] for a description of shared-cache locking. 
** ^This API may be used to register a callback that SQLite will invoke 
** when the connection currently holding the required lock relinquishes it.
** ^This API is only available if the library was compiled with the
** [SQLITE_ENABLE_UNLOCK_NOTIFY] C-preprocessor symbol defined.
**
** See Also: [Using the SQLite Unlock Notification Feature].
**
** ^Shared-cache locks are released when a database connection concludes
** its current transaction, either by committing it or rolling it back. 
**
** ^When a connection (known as the blocked connection) fails to obtain a
** shared-cache lock and SQLITE_LOCKED is returned to the caller, the
** identity of the database connection (the blocking connection) that
** has locked the required resource is stored internally. ^After an 
** application receives an SQLITE_LOCKED error, it may call the
** sqlite3_unlock_notify() method with the blocked connection handle as 
** the first argument to register for a callback that will be invoked
** when the blocking connections current transaction is concluded. ^The
** callback is invoked from within the [sqlite3_step] or [sqlite3_close]
** call that concludes the blocking connections transaction.
**
** ^(If sqlite3_unlock_notify() is called in a multi-threaded application,
** there is a chance that the blocking connection will have already
** concluded its transaction by the time sqlite3_unlock_notify() is invoked.
** If this happens, then the specified callback is invoked immediately,
** from within the call to sqlite3_unlock_notify().)^
**
** ^If the blocked connection is attempting to obtain a write-lock on a
** shared-cache table, and more than one other connection currently holds
** a read-lock on the same table, then SQLite arbitrarily selects one of 
** the other connections to use as the blocking connection.
**
** ^(There may be at most one unlock-notify callback registered by a 
** blocked connection. If sqlite3_unlock_notify() is called when the
** blocked connection already has a registered unlock-notify callback,
** then the new callback replaces the old.)^ ^If sqlite3_unlock_notify() is
** called with a NULL pointer as its second argument, then any existing
** unlock-notify callback is canceled. ^The blocked connections 
** unlock-notify callback may also be canceled by closing the blocked
** connection using [sqlite3_close()].
**
** The unlock-notify callback is not reentrant. If an application invokes
** any sqlite3_xxx API functions from within an unlock-notify callback, a
** crash or deadlock may be the result.
**
** ^Unless deadlock is detected (see below), sqlite3_unlock_notify() always
** returns SQLITE_OK.
**
** <b>Callback Invocation Details</b>
**
** When an unlock-notify callback is registered, the application provides a 
** single void* pointer that is passed to the callback when it is invoked.
** However, the signature of the callback function allows SQLite to pass
** it an array of void* context pointers. The first argument passed to
** an unlock-notify callback is a pointer to an array of void* pointers,
** and the second is the number of entries in the array.
**
** When a blocking connections transaction is concluded, there may be
** more than one blocked connection that has registered for an unlock-notify
** callback. ^If two or more such blocked connections have specified the
** same callback function, then instead of invoking the callback function
** multiple times, it is invoked once with the set of void* context pointers
** specified by the blocked connections bundled together into an array.
** This gives the application an opportunity to prioritize any actions 
** related to the set of unblocked database connections.
**
** <b>Deadlock Detection</b>
**
** Assuming that after registering for an unlock-notify callback a 
** database waits for the callback to be issued before taking any further
** action (a reasonable assumption), then using this API may cause the
** application to deadlock. For example, if connection X is waiting for
** connection Y's transaction to be concluded, and similarly connection
** Y is waiting on connection X's transaction, then neither connection
** will proceed and the system may remain deadlocked indefinitely.
**
** To avoid this scenario, the sqlite3_unlock_notify() performs deadlock
** detection. ^If a given call to sqlite3_unlock_notify() would put the
** system in a deadlocked state, then SQLITE_LOCKED is returned and no
** unlock-notify callback is registered. The system is said to be in
** a deadlocked state if connection A has registered for an unlock-notify
** callback on the conclusion of connection B's transaction, and connection
** B has itself registered for an unlock-notify callback when connection
** A's transaction is concluded. ^Indirect deadlock is also detected, so
** the system is also considered to be deadlocked if connection B has
** registered for an unlock-notify callback on the conclusion of connection
** C's transaction, where connection C is waiting on connection A. ^Any
** number of levels of indirection are allowed.
**
** <b>The "DROP TABLE" Exception</b>
**
** When a call to [sqlite3_step()] returns SQLITE_LOCKED, it is almost 
** always appropriate to call sqlite3_unlock_notify(). There is however,
** one exception. When executing a "DROP TABLE" or "DROP INDEX" statement,
** SQLite checks if there are any currently executing SELECT statements
** that belong to the same connection. If there are, SQLITE_LOCKED is
** returned. In this case there is no "blocking connection", so invoking
** sqlite3_unlock_notify() results in the unlock-notify callback being
** invoked immediately. If the application then re-attempts the "DROP TABLE"
** or "DROP INDEX" query, an infinite loop might be the result.
**
** One way around this problem is to check the extended error code returned

** will be invoked each time a database connection commits data to a
** [write-ahead log] (i.e. whenever a transaction is committed in
** [journal_mode | journal_mode=WAL mode]). 
**
** ^The callback is invoked by SQLite after the commit has taken place and 
** the associated write-lock on the database released, so the implementation 
** may read, write or [checkpoint] the database as required.
**
** ^The first parameter passed to the callback function when it is invoked
** is a copy of the third parameter passed to sqlite3_wal_hook() when
** registering the callback. ^The second is a copy of the database handle.
** ^The third parameter is the name of the database that was written to -
** either "main" or the name of an [ATTACH]-ed database. ^The fourth parameter
** is the number of pages currently in the write-ahead log file,
** including those that were just committed.
**
** The callback function should normally return [SQLITE_OK].  ^If an error
** code is returned, that error will propagate back up through the
** SQLite code base to cause the statement that provoked the callback
** to report an error, though the commit will have still occurred. If the
** callback returns [SQLITE_ROW] or [SQLITE_DONE], or if it returns a value
** that does not correspond to any valid SQLite error code, the results
** are undefined.
**
** A single database handle may have at most a single write-ahead log callback 
** registered at one time. ^Calling [sqlite3_wal_hook()] replaces any
** previously registered write-ahead log callback. ^Note that the
** [sqlite3_wal_autocheckpoint()] interface and the

**
** <dl>
** <dt>SQLITE_CHECKPOINT_PASSIVE<dd>
**   Checkpoint as many frames as possible without waiting for any database 
**   readers or writers to finish. Sync the db file if all frames in the log
**   are checkpointed. This mode is the same as calling 
**   sqlite3_wal_checkpoint(). The busy-handler callback is never invoked.
**
** <dt>SQLITE_CHECKPOINT_FULL<dd>
**   This mode blocks (calls the busy-handler callback) until there is no
**   database writer and all readers are reading from the most recent database
**   snapshot. It then checkpoints all frames in the log file and syncs the
**   database file. This call blocks database writers while it is running,
**   but not database readers.
**
** <dt>SQLITE_CHECKPOINT_RESTART<dd>
**   This mode works the same way as SQLITE_CHECKPOINT_FULL, except after 
**   checkpointing the log file it blocks (calls the busy-handler callback)
**   until all readers are reading from the database file only. This ensures 
**   that the next client to write to the database file restarts the log file 
**   from the beginning. This call blocks database writers while it is running,
**   but not database readers.
** </dl>
**
** If pnLog is not NULL, then *pnLog is set to the total number of frames in
** the log file before returning. If pnCkpt is not NULL, then *pnCkpt is set to
** the total number of checkpointed frames (including any that were already
** checkpointed when this function is called). *pnLog and *pnCkpt may be
** populated even if sqlite3_wal_checkpoint_v2() returns other than SQLITE_OK.
** If no values are available because of an error, they are both set to -1
** before returning to communicate this to the caller.
**
** All calls obtain an exclusive "checkpoint" lock on the database file. If
** any other process is running a checkpoint operation at the same time, the 
** lock cannot be obtained and SQLITE_BUSY is returned. Even if there is a 
** busy-handler configured, it will not be invoked in this case.
**
** The SQLITE_CHECKPOINT_FULL and RESTART modes also obtain the exclusive 
** "writer" lock on the database file. If the writer lock cannot be obtained
** immediately, and a busy-handler is configured, it is invoked and the writer
** lock retried until either the busy-handler returns 0 or the lock is
** successfully obtained. The busy-handler is also invoked while waiting for
** database readers as described above. If the busy-handler returns 0 before
** the writer lock is obtained or while waiting for database readers, the
** checkpoint operation proceeds from that point in the same way as 
** SQLITE_CHECKPOINT_PASSIVE - checkpointing as many frames as possible 
** without blocking any further. SQLITE_BUSY is returned in this case.
**
** If parameter zDb is NULL or points to a zero length string, then the
** specified operation is attempted on all WAL databases. In this case the
** values written to output parameters *pnLog and *pnCkpt are undefined. If 
** an SQLITE_BUSY error is encountered when processing one or more of the 
** attached WAL databases, the operation is still attempted on any remaining 
** attached databases and SQLITE_BUSY is returned to the caller. If any other 
** error occurs while processing an attached database, processing is abandoned 
** and the error code returned to the caller immediately. If no error 
** (SQLITE_BUSY or otherwise) is encountered while processing the attached 
** databases, SQLITE_OK is returned.
**
** If database zDb is the name of an attached database that is not in WAL
** mode, SQLITE_OK is returned and both *pnLog and *pnCkpt set to -1. If
** zDb is not NULL (or a zero length string) and is not the name of any
** attached database, SQLITE_ERROR is returned to the caller.

** support constraints.  In this configuration (which is the default) if

** statement is rolled back as if [ON CONFLICT | OR ABORT] had been
** specified as part of the users SQL statement, regardless of the actual
** ON CONFLICT mode specified.
**
** If X is non-zero, then the virtual table implementation guarantees
** that if [xUpdate] returns [SQLITE_CONSTRAINT], it will do so before
** any modifications to internal or persistent data structures have been made.
** If the [ON CONFLICT] mode is ABORT, FAIL, IGNORE or ROLLBACK, SQLite 
** is able to roll back a statement or database transaction, and abandon

** had been ABORT.

** Virtual table implementations that are required to handle OR REPLACE
** must do so within the [xUpdate] method. If a call to the

** CONFLICT policy is REPLACE, the virtual table implementation should 
** silently replace the appropriate rows within the xUpdate callback and

** This file contains the C functions that implement date and time

**
** NOTES:
**
** SQLite processes all times and dates as Julian Day numbers.  The
** dates and times are stored as the number of days since noon
** in Greenwich on November 24, 4714 B.C. according to the Gregorian
** calendar system.
**
** 1970-01-01 00:00:00 is JD 2440587.5
** 2000-01-01 00:00:00 is JD 2451544.5
**
** This implemention requires years to be expressed as a 4-digit number
** which means that only dates between 0000-01-01 and 9999-12-31 can
** be represented, even though julian day numbers allow a much wider
** range of dates.
**
** The Gregorian calendar system is used for all dates and times,
** even those that predate the Gregorian calendar.  Historians usually
** use the Julian calendar for dates prior to 1582-10-15 and for some
** dates afterwards, depending on locale.  Beware of this difference.
**
** The conversion algorithms are implemented based on descriptions
** in the following text:

** This routine is call to handle SQL of the following forms:
**
**    insert into TABLE (IDLIST) values(EXPRLIST)
**    insert into TABLE (IDLIST) select
**
** The IDLIST following the table name is always optional.  If omitted,
** then a list of all columns for the table is substituted.  The IDLIST
** appears in the pColumn parameter.  pColumn is NULL if IDLIST is omitted.
**
** The pList parameter holds EXPRLIST in the first form of the INSERT
** statement above, and pSelect is NULL.  For the second form, pList is
** NULL and pSelect is a pointer to the select statement used to generate
** data for the insert.
**
** The code generated follows one of three templates.  For a simple
** select with data coming from a VALUES clause, the code executes
** once straight down through.  The template looks like this:
**
**         open write cursor to <table> and its indices
**         puts VALUES clause expressions onto the stack
**         write the resulting record into <table>
**         cleanup
**
** If the statement is of the form
**
**   INSERT INTO <table> SELECT ...
**
** And the SELECT clause does not read from <table> at any time, then
** the generated code follows this template:
**
**         goto B
**      A: setup for the SELECT
**         loop over the tables in the SELECT
**           gosub C
**         end loop
**         cleanup after the SELECT
**         goto D
**      B: open write cursor to <table> and its indices
**         goto A
**      C: insert the select result into <table>
**         return
**      D: cleanup
**
** The third template is used if the insert statement takes its
** values from a SELECT but the data is being inserted into a table
** that is also read as part of the SELECT.  In the third form,
** we have to use a intermediate table to store the results of
** the select.  The template is like this:
**
**         goto B
**      A: setup for the SELECT
**         loop over the tables in the SELECT
**           gosub C
**         end loop
**         cleanup after the SELECT
**         goto D
**      C: insert the select result into the intermediate table
**         return
**      B: open a cursor to an intermediate table
**         goto A
**      D: open write cursor to <table> and its indices
**         loop over the intermediate table
**           transfer values form intermediate table into <table>
**         end the loop
**         cleanup

** Generate code to do a constraint check prior to an INSERT or an UPDATE.

**        value is omitted unless we are doing an UPDATE that involves a
**        change to the record number.
**
**    2.  The recno of the row after the update.
**
**    3.  The data in the first column of the entry after the update.
**
**    i.  Data from middle columns...
**
**    N.  The data in the last column of the entry after the update.
**
** The old recno shown as entry (1) above is omitted unless both isUpdate
** and recnoChng are 1.  isUpdate is true for UPDATEs and false for
** INSERTs and recnoChng is true if the record number is being changed.
**
** The code generated by this routine pushes additional entries onto
** the stack which are the keys for new index entries for the new record.
** The order of index keys is the same as the order of the indices on
** the pTable->pIndex list.  A key is only created for index i if 
** aIdxUsed!=0 and aIdxUsed[i]!=0.
**
** This routine also generates code to check constraints.  NOT NULL,
** CHECK, and UNIQUE constraints are all checked.  If a constraint fails,
** then the appropriate action is performed.  There are five possible
** actions: ROLLBACK, ABORT, FAIL, REPLACE, and IGNORE.
**
**  Constraint type  Action       What Happens
**  ---------------  ----------   ----------------------------------------
**  any              ROLLBACK     The current transaction is rolled back and
**                                sqlite3_exec() returns immediately with a
**                                return code of SQLITE_CONSTRAINT.
**
**  any              ABORT        Back out changes from the current command
**                                only (do not do a complete rollback) then
**                                cause sqlite3_exec() to return immediately
**                                with SQLITE_CONSTRAINT.
**
**  any              FAIL         Sqlite_exec() returns immediately with a
**                                return code of SQLITE_CONSTRAINT.  The
**                                transaction is not rolled back and any
**                                prior changes are retained.
**
**  any              IGNORE       The record number and data is popped from
**                                the stack and there is an immediate jump
**                                to label ignoreDest.
**
**  NOT NULL         REPLACE      The NULL value is replace by the default
**                                value for that column.  If the default value
**                                is NULL, the action is the same as ABORT.
**
**  UNIQUE           REPLACE      The other row that conflicts with the row
**                                being inserted is removed.
**
**  CHECK            REPLACE      Illegal.  The results in an exception.
**
** Which action to take is determined by the overrideError parameter.
** Or if overrideError==OE_Default, then the pParse->onError parameter
** is used.  Or if pParse->onError==OE_Default then the onError value
** for the constraint is used.
**
** The calling routine must open a read/write cursor for pTab with
** cursor number "base".  All indices of pTab must also have open
** read/write cursors with cursor number base+i for the i-th cursor.
** Except, if there is no possibility of a REPLACE action then
** cursors do not need to be open for indices where aIdxUsed[i]==0.
**
** If the isUpdate flag is true, it means that the "base" cursor is
** initially pointing to an entry that is being updated.  The isUpdate
** flag causes extra code to be generated so that the "base" cursor
** is still pointing at the same entry after the routine returns.
** Without the isUpdate flag, the "base" cursor might be moved.

/*
** File Locking Notes:  (Mostly about windows but also some info for Unix)
**
** We cannot use LockFileEx() or UnlockFileEx() on Win95/98/ME because
** those functions are not available.  So we use only LockFile() and
** UnlockFile().
**
** LockFile() prevents not just writing but also reading by other processes.
** A SHARED_LOCK is obtained by locking a single randomly-chosen 
** byte out of a specific range of bytes. The lock byte is obtained at 
** random so two separate readers can probably access the file at the 
** same time, unless they are unlucky and choose the same lock byte.
** An EXCLUSIVE_LOCK is obtained by locking all bytes in the range.
** There can only be one writer.  A RESERVED_LOCK is obtained by locking
** a single byte of the file that is designated as the reserved lock byte.
** A PENDING_LOCK is obtained by locking a designated byte different from
** the RESERVED_LOCK byte.
**
** On WinNT/2K/XP systems, LockFileEx() and UnlockFileEx() are available,
** which means we can use reader/writer locks.  When reader/writer locks
** are used, the lock is placed on the same range of bytes that is used
** for probabilistic locking in Win95/98/ME.  Hence, the locking scheme
** will support two or more Win95 readers or two or more WinNT readers.
** But a single Win95 reader will lock out all WinNT readers and a single
** WinNT reader will lock out all other Win95 readers.
**
** The following #defines specify the range of bytes used for locking.
** SHARED_SIZE is the number of bytes available in the pool from which
** a random byte is selected for a shared lock.  The pool of bytes for
** shared locks begins at SHARED_FIRST. 
**
** These #defines are available in os.h so that Unix can use the same
** byte ranges for locking.  This leaves open the possiblity of having
** clients on win95, winNT, and unix all talking to the same shared file
** and all locking correctly.  To do so would require that samba (or whatever
** tool is being used for file sharing) implements locks correctly between
** windows and unix.  I'm guessing that isn't likely to happen, but by
** using the same locking range we are at least open to the possibility.
**
** Locking in windows is manditory.  For this reason, we cannot store
** actual data in the bytes used for locking.  The pager never allocates
** the pages involved in locking therefore.  SHARED_SIZE is selected so
** that all locks will fit on a single page even at the minimum page size.
** PENDING_BYTE defines the beginning of the locks.  By default PENDING_BYTE
** is set high so that we don't have to allocate an unused page except
** for very large databases.  But one should test the page skipping logic 
** by setting PENDING_BYTE low and running the entire regression suite.
**
** Changing the value of PENDING_BYTE results in a subtly incompatible
** file format.  Depending on how it is changed, you might not notice
** the incompatibility right away, even running a full regression test.
** The default location of PENDING_BYTE is the first byte past the
** 1GB boundary.

** Here is the dirt on POSIX advisory locks:  ANSI STD 1003.1 (1996)
** section 6.5.2.2 lines 483 through 490 specify that when a process
** sets or clears a lock, that operation overrides any prior locks set
** by the same process.  It does not explicitly say so, but this implies
** that it overrides locks set by the same process using a different
** file descriptor.  Consider this test case:
**
**       int fd1 = open("./file1", O_RDWR|O_CREAT, 0644);
**       int fd2 = open("./file2", O_RDWR|O_CREAT, 0644);
**
** Suppose ./file1 and ./file2 are really the same file (because
** one is a hard or symbolic link to the other) then if you set
** an exclusive lock on fd1, then try to get an exclusive lock
** on fd2, it works.  I would have expected the second lock to
** fail since there was already a lock on the file due to fd1.
** But not so.  Since both locks came from the same process, the
** second overrides the first, even though they were on different
** file descriptors opened on different file names.
**
** Bummer.  If you ask me, this is broken.  Badly broken.  It means
** that we cannot use POSIX locks to synchronize file access among
** competing threads of the same process.  POSIX locks will work fine
** to synchronize access for threads in separate processes, but not
** threads within the same process.
**
** To work around the problem, SQLite has to manage file locks internally
** on its own.  Whenever a new database is opened, we have to find the
** specific inode of the database file (the inode is determined by the
** st_dev and st_ino fields of the stat structure that fstat() fills in)
** and check for locks already existing on that inode.  When locks are
** created or removed, we have to look at our own internal record of the
** locks to see if another thread has previously set a lock on that same
** inode.
**
** The OsFile structure for POSIX is no longer just an integer file
** descriptor.  It is now a structure that holds the integer file
** descriptor and a pointer to a structure that describes the internal
** locks on the corresponding inode.  There is one locking structure
** per inode, so if the same inode is opened twice, both OsFile structures
** point to the same locking structure.  The locking structure keeps
** a reference count (so we will know when to delete it) and a "cnt"
** field that tells us its internal lock status.  cnt==0 means the
** file is unlocked.  cnt==-1 means the file has an exclusive lock.
** cnt>0 means there are cnt shared locks on the file.
**
** Any attempt to lock or unlock a file first checks the locking
** structure.  The fcntl() system call is only invoked to set a 
** POSIX lock if the internal lock structure transitions between
** a locked and an unlocked state.
**
** 2004-Jan-11:
** More recent discoveries about POSIX advisory locks.  (The more
** I discover, the more I realize the a POSIX advisory locks are
** an abomination.)
**
** If you close a file descriptor that points to a file that has locks,
** all locks on that file that are owned by the current process are
** released.  To work around this problem, each OsFile structure contains
** a pointer to an openCnt structure.  There is one openCnt structure
** per open inode, which means that multiple OsFiles can point to a single
** openCnt.  When an attempt is made to close an OsFile, if there are
** other OsFiles open on the same inode that are holding locks, the call
** to close() the file descriptor is deferred until all of the locks clear.
** The openCnt structure keeps a list of file descriptors that need to
** be closed and that list is walked (and cleared) when the last lock
** clears.
**
** First, under Linux threads, because each thread has a separate
** process ID, lock operations in one thread do not override locks
** to the same file in other threads.  Linux threads behave like
** separate processes in this respect.  But, if you close a file
** descriptor in linux threads, all locks are cleared, even locks
** on other threads and even though the other threads have different
** process IDs.  Linux threads is inconsistent in this respect.
** (I'm beginning to think that linux threads is an abomination too.)
** The consequence of this all is that the hash table for the lockInfo
** structure has to include the process id as part of its key because
** locks in different threads are treated as distinct.  But the 
** openCnt structure should not include the process id in its
** key because close() clears lock on all threads, not just the current
** thread.  Were it not for this goofiness in linux threads, we could
** combine the lockInfo and openCnt structures into a single structure.
**
** 2004-Jun-28:
** On some versions of linux, threads can override each others locks.
** On others not.  Sometimes you can change the behavior on the same
** system by setting the LD_ASSUME_KERNEL environment variable.  The
** POSIX standard is silent as to which behavior is correct, as far
** as I can tell, so other versions of unix might show the same
** inconsistency.  There is no little doubt in my mind that posix
** advisory locks and linux threads are profoundly broken.
**
** To work around the inconsistencies, we have to test at runtime 
** whether or not threads can override each others locks.  This test
** is run once, the first time any lock is attempted.  A static 
** variable is set to record the results of this test for future
** use.

  ** confusion with SQLite lock names). The algorithms are complicated
  ** slightly in order to be compatible with windows systems simultaneously
  ** accessing the same database file, in case that is ever required.
  **
  ** Symbols defined in os.h indentify the 'pending byte' and the 'reserved
  ** byte', each single bytes at well known offsets, and the 'shared byte
  ** range', a range of 510 bytes at a well known offset.
  **
  ** To obtain a SHARED lock, a read-lock is obtained on the 'pending
  ** byte'.  If this is successful, a random byte from the 'shared byte
  ** range' is read-locked and the lock on the 'pending byte' released.
  **
  ** A process may only obtain a RESERVED lock after it has a SHARED lock.
  ** A RESERVED lock is implemented by grabbing a write-lock on the
  ** 'reserved byte'. 
  **
  ** A process may only obtain a PENDING lock after it has obtained a
  ** SHARED lock. A PENDING lock is implemented by obtaining a write-lock
  ** on the 'pending byte'. This ensures that no new SHARED locks can be
  ** obtained, but existing SHARED locks are allowed to persist. A process
  ** does not have to obtain a RESERVED lock on the way to a PENDING lock.
  ** This property is used by the algorithm for rolling back a journal file
  ** after a crash.
  **
  ** An EXCLUSIVE lock, obtained after a PENDING lock is held, is
  ** implemented by obtaining a write-lock on the entire 'shared byte
  ** range'. Since all other locks require a read-lock on one of the bytes
  ** within this range, this ensures that no other locks are held on the
  ** database. 
  **
  ** The reason a single byte cannot be used instead of the 'shared byte
  ** range' is that some versions of windows do not support read-locks. By
  ** locking a random byte from a range, concurrent SHARED locks may exist
  ** even if the locking primitive used is always a write-lock.

** The page cache as a whole is always in one of the following
** states:
**
**   PAGER_UNLOCK        The page cache is not currently reading or 
**                       writing the database file.  There is no
**                       data held in memory.  This is the initial
**                       state.
**
**   PAGER_SHARED        The page cache is reading the database.
**                       Writing is not permitted.  There can be
**                       multiple readers accessing the same database
**                       file at the same time.
**
**   PAGER_RESERVED      This process has reserved the database for writing
**                       but has not yet made any changes.  Only one process
**                       at a time can reserve the database.  The original
**                       database file has not been modified so other
**                       processes may still be reading the on-disk
**                       database file.
**
**   PAGER_EXCLUSIVE     The page cache is writing the database.
**                       Access is exclusive.  No other processes or
**                       threads can be reading or writing while one
**                       process is writing.
**
**   PAGER_SYNCED        The pager moves to this state from PAGER_EXCLUSIVE
**                       after all dirty pages have been written to the
**                       database file and the file has been synced to
**                       disk. All that remains to do is to remove the
**                       journal file and the transaction will be
**                       committed.
**
** The page cache comes up in PAGER_UNLOCK.  The first time a
** sqlite3pager_get() occurs, the state transitions to PAGER_SHARED.
** After all pages have been released using sqlite_page_unref(),
** the state transitions back to PAGER_UNLOCK.  The first time
** that sqlite3pager_write() is called, the state transitions to
** PAGER_RESERVED.  (Note that sqlite_page_write() can only be
** called on an outstanding page which means that the pager must
** be in PAGER_SHARED before it transitions to PAGER_RESERVED.)
** The transition to PAGER_EXCLUSIVE occurs when before any changes
** are made to the database file.  After an sqlite3pager_rollback()
** or sqlite_pager_commit(), the state goes back to PAGER_SHARED.

** Thread B already has a reserved lock and wants an exclusive lock.  If
** both threads are using their busy callbacks, it might be a long time

**  (2)  4 byte big-endian integer which is the number of valid page records
**       in the journal.  If this value is 0xffffffff, then compute the
**       number of page records from the journal size.
**  (3)  4 byte big-endian integer which is the initial value for the 
**       sanity checksum.
**  (4)  4 byte integer which is the number of pages to truncate the
**       database to during a rollback.
**  (5)  4 byte integer which is the number of bytes in the master journal
**       name.  The value may be zero (indicate that there is no master
**       journal.)
**  (6)  N bytes of the master journal name.  The name will be nul-terminated
**       and might be shorter than the value read from (5).  If the first byte
**       of the name is \000 then there is no master journal.  The master
**       journal name is stored in UTF-8.
**  (7)  Zero or more pages instances, each as follows:
**        +  4 byte page number.
**        +  pPager->pageSize bytes of data.
**        +  4 byte checksum
**
** When we speak of the journal header, we mean the first 6 items above.
** Each entry in the journal is an instance of the 7th item.
**
** Call the value from the second bullet "nRec".  nRec is the number of
** valid page entries in the journal.  In most cases, you can compute the
** value of nRec from the size of the journal file.  But if a power
** failure occurred while the journal was being written, it could be the
** case that the size of the journal file had already been increased but
** the extra entries had not yet made it safely to disk.  In such a case,
** the value of nRec computed from the file size would be too large.  For
** that reason, we always use the nRec value in the header.
**
** If the nRec value is 0xffffffff it means that nRec should be computed
** from the file size.  This value is used when the user selects the
** no-sync option for the journal.  A power failure could lead to corruption
** in this case.  But for things like temporary table (which will be
** deleted when the power is restored) we don't care.  
**
** If the file opened as the journal file is not a well-formed
** journal file then all pages up to the first corrupted page are rolled
** back (or no pages if the journal header is corrupted). The journal file
** is then deleted and SQLITE_OK returned, just as if no corruption had
** been encountered.

** If an I/O or malloc() error occurs, the journal-file is not deleted

**    YYCODETYPE         is the data type used for storing terminal
**                       and nonterminal numbers.  "unsigned char" is
**                       used if there are fewer than 250 terminals
**                       and nonterminals.  "int" is used otherwise.
**    YYNOCODE           is a number of type YYCODETYPE which corresponds
**                       to no legal terminal or nonterminal number.  This
**                       number is used to fill in empty slots of the hash 
**                       table.
**    YYFALLBACK         If defined, this indicates that one or more tokens
**                       have fall-back values which should be used if the
**                       original value of the token will not parse.
**    YYACTIONTYPE       is the data type used for storing terminal
**                       and nonterminal numbers.  "unsigned char" is
**                       used if there are fewer than 250 rules and
**                       states combined.  "int" is used otherwise.
**    sqlite3ParserTOKENTYPE     is the data type used for minor tokens given 
**                       directly to the parser from the tokenizer.
**    YYMINORTYPE        is the data type used for all minor tokens.
**                       This is typically a union of many types, one of
**                       which is sqlite3ParserTOKENTYPE.  The entry in the union
**                       for base tokens is called "yy0".
**    YYSTACKDEPTH       is the maximum depth of the parser's stack.
**    sqlite3ParserARG_SDECL     A static variable declaration for the %extra_argument
**    sqlite3ParserARG_PDECL     A parameter declaration for the %extra_argument
**    sqlite3ParserARG_STORE     Code to store %extra_argument into yypParser
**    sqlite3ParserARG_FETCH     Code to extract %extra_argument from yypParser
**    YYNSTATE           the combined number of states.
**    YYNRULE            the number of rules in the grammar
**    YYERRORSYMBOL      is the code number of the error symbol.  If not
**                       defined, then do no error processing.

/* Next are that tables used to determine what action to take based on the
** current state and lookahead token.  These tables are used to implement
** functions that take a state number and lookahead value and return an
** action integer.  
**
** Suppose the action integer is N.  Then the action is determined as
** follows
**
**   0 <= N < YYNSTATE                  Shift N.  That is, push the lookahead
**                                      token onto the stack and goto state N.
**
**   YYNSTATE <= N < YYNSTATE+YYNRULE   Reduce by rule N-YYNSTATE.
**
**   N == YYNSTATE+YYNRULE              A syntax error has occurred.
**
**   N == YYNSTATE+YYNRULE+1            The parser accepts its input.
**
**   N == YYNSTATE+YYNRULE+2            No such action.  Denotes unused
**                                      slots in the yy_action[] table.
**
** The action table is constructed as a single large table named yy_action[].
** Given state S and lookahead X, the action is computed as
**
**      yy_action[ yy_shift_ofst[S] + X ]
**
** If the index value yy_shift_ofst[S]+X is out of range or if the value
** yy_lookahead[yy_shift_ofst[S]+X] is not equal to X or if yy_shift_ofst[S]
** is equal to YY_SHIFT_USE_DFLT, it means that the action is not in the table
** and that yy_default[S] should be used instead.  
**
** The formula above is for computing the action when the lookahead is
** a terminal symbol.  If the lookahead is a non-terminal (as occurs after
** a reduce action) then the yy_reduce_ofst[] array is used in place of
** the yy_shift_ofst[] array and YY_REDUCE_USE_DFLT is used in place of
** YY_SHIFT_USE_DFLT.
**
** The following are the tables generated in this section:
**
**  yy_action[]        A single table containing all actions.
**  yy_lookahead[]     A table containing the lookahead for each entry in
**                     yy_action.  Used to detect hash collisions.
**  yy_shift_ofst[]    For each state, the offset into yy_action for
**                     shifting terminals.
**  yy_reduce_ofst[]   For each state, the offset into yy_action for
**                     shifting non-terminals after a reduce.
**  yy_default[]       Default action for each state.

/*
** The "printf" code that follows dates from the 1980's.  It is in
** the public domain.  The original comments are included here for
** completeness.  They are very out-of-date but might be useful as
** an historical reference.  Most of the "enhancements" have been backed
** out so that the functionality is now the same as standard printf().
**
**************************************************************************
**
** The following modules is an enhanced replacement for the "printf" subroutines
** found in the standard C library.  The following enhancements are
** supported:
**
**      +  Additional functions.  The standard set of "printf" functions
**         includes printf, fprintf, sprintf, vprintf, vfprintf, and
**         vsprintf.  This module adds the following:
**
**           *  snprintf -- Works like sprintf, but has an extra argument
**                          which is the size of the buffer written to.
**
**           *  mprintf --  Similar to sprintf.  Writes output to memory
**                          obtained from malloc.
**
**           *  xprintf --  Calls a function to dispose of output.
**
**           *  nprintf --  No output, but returns the number of characters
**                          that would have been output by printf.
**
**           *  A v- version (ex: vsnprintf) of every function is also
**              supplied.
**
**      +  A few extensions to the formatting notation are supported:
**
**           *  The "=" flag (similar to "-") causes the output to be
**              be centered in the appropriately sized field.
**
**           *  The %b field outputs an integer in binary notation.
**
**           *  The %c field now accepts a precision.  The character output
**              is repeated by the number of times the precision specifies.
**
**           *  The %' field works like %c, but takes as its character the
**              next character of the format string, instead of the next
**              argument.  For example,  printf("%.78'-")  prints 78 minus
**              signs, the same as  printf("%.78c",'-').
**
**      +  When compiled using GCC on a SPARC, this version of printf is
**         faster than the library printf for SUN OS 4.1.
**
**      +  All functions are fully reentrant.

** INPUTS:
**   func   This is a pointer to a function taking three arguments
**            1. A pointer to anything.  Same as the "arg" parameter.
**            2. A pointer to the list of characters to be output
**               (Note, this list is NOT null terminated.)
**            3. An integer number of characters to be output.
**               (Note: This number might be zero.)
**
**   arg    This is the pointer to anything which will be passed as the
**          first argument to "func".  Use it for whatever you like.
**
**   fmt    This is the format string, as in the usual print.
**
**   ap     This is a pointer to a list of arguments.  Same as in
**          vfprint.
**
** OUTPUTS:
**          The return value is the total number of characters sent to
**          the function "func".  Returns -1 on a error.
**
** Note that the order in which automatic variables are declared below
** seems to make a big difference in determining how fast this beast
** will run.

** This routine attempts to flatten subqueries in order to speed
** execution.  It returns 1 if it makes changes and 0 if no flattening
** occurs.
**
** To understand the concept of flattening, consider the following
** query:
**
**     SELECT a FROM (SELECT x+y AS a FROM t1 WHERE z<100) WHERE a>5
**
** The default way of implementing this query is to execute the
** subquery first and store the results in a temporary table, then
** run the outer query on that temporary table.  This requires two
** passes over the data.  Furthermore, because the temporary table
** has no indices, the WHERE clause on the outer query cannot be
** optimized.
**
** This routine attempts to rewrite queries such as the above into
** a single flat select, like this:
**
**     SELECT x+y AS a FROM t1 WHERE z<100 AND a>5
**
** The code generated for this simpification gives the same result
** but only has to scan the data once.  And because indices might 
** exist on the table t1, a complete scan of the data might be
** avoided.
**
** Flattening is only attempted if all of the following are true:
**
**   (1)  The subquery and the outer query do not both use aggregates.
**
**   (2)  The subquery is not an aggregate or the outer query is not a join.
**
**   (3)  The subquery is not the right operand of a left outer join, or
**        the subquery is not itself a join.  (Ticket #306)
**
**   (4)  The subquery is not DISTINCT or the outer query is not a join.
**
**   (5)  The subquery is not DISTINCT or the outer query does not use
**        aggregates.
**
**   (6)  The subquery does not use aggregates or the outer query is not
**        DISTINCT.
**
**   (7)  The subquery has a FROM clause.
**
**   (8)  The subquery does not use LIMIT or the outer query is not a join.
**
**   (9)  The subquery does not use LIMIT or the outer query does not use
**        aggregates.
**
**  (10)  The subquery does not use aggregates or the outer query does not
**        use LIMIT.
**
**  (11)  The subquery and the outer query do not both have ORDER BY clauses.
**
**  (12)  The subquery is not the right term of a LEFT OUTER JOIN or the
**        subquery has no WHERE clause.  (added by ticket #350)
**
** In this routine, the "p" parameter is a pointer to the outer query.
** The subquery is p->pSrc->a[iFrom].  isAgg is true if the outer query
** uses aggregates and subqueryIsAgg is true if the subquery uses aggregates.
**
** If flattening is not attempted, this routine is a no-op and returns 0.
** If flattening is attempted this routine returns 1.
**
** All of the expression analysis must occur on both the outer query and
** the subquery before this routine runs.

** string from the argument list.  But %q also doubles every '\'' character.
** %q is designed for use inside a string literal.  By doubling each '\''
** character it escapes that character and allows it to be inserted into
** the string.
**
** For example, so some string variable contains text as follows:
**
**      char *zText = "It's a happy day!";

**
**      sqlite3_exec_printf(db, "INSERT INTO table VALUES('%q')",

** minimize conversions between text encodings.

** pointers to user implemented C functions that implement the user
** function or aggregate. A scalar function requires an implementation of

** code representing the ">=" operator.  This same integer code is reused
** to represent the greater-than-or-equal-to operator in the expression
** tree.
**
** Expr.pRight and Expr.pLeft are subexpressions.  Expr.pList is a list
** of argument if the expression is a function.
**
** Expr.token is the operator token for this node.  For some expressions
** that have subexpressions, Expr.token can be the complete text that gave
** rise to the Expr.  In the latter case, the token is marked as being
** a compound token.
**
** An expression of the form ID or ID.ID refers to a column in a table.
** For such expressions, Expr.op is set to TK_COLUMN and Expr.iTable is
** the integer cursor number of a VDBE cursor pointing to that table and
** Expr.iColumn is the column number for the specific column.  If the
** expression is used as a result in an aggregate SELECT, then the
** value is also stored in the Expr.iAgg column in the aggregate so that
** it can be accessed after all aggregates are computed.
**
** If the expression is a function, the Expr.iTable is an integer code
** representing which function.  If the expression is an unbound variable
** marker (a question mark character '?' in the original SQL) then the
** Expr.iTable holds the index number for that variable.
**
** If the expression is a subquery then Expr.iColumn holds an integer
** register number containing the result of the subquery.  If the
** subquery gives a constant result, then iTable is -1.  If the subquery
** gives a different answer at different times during statement processing
** then iTable is the address of a subroutine that computes the subquery.
**
** The Expr.pSelect field points to a SELECT statement.  The SELECT might
** be the right operand of an IN operator.  Or, if a scalar SELECT appears
** in an expression the opcode is TK_SELECT and Expr.pSelect is the only

 * An instance of struct TriggerStack stores information required during code
 * generation of a single trigger program. While the trigger program is being
 * coded, its associated TriggerStack instance is pointed to by the
 * "pTriggerStack" member of the Parse structure.
 *
 * The pTab member points to the table that triggers are being coded on. The 
 * newIdx member contains the index of the vdbe cursor that points at the temp
 * table that stores the new.* references. If new.* references are not valid
 * for the trigger being coded (for example an ON DELETE trigger), then newIdx
 * is set to -1. The oldIdx member is analogous to newIdx, for old.* references.
 *
 * The ON CONFLICT policy to be used for the trigger program steps is stored 
 * as the orconf member. If this is OE_Default, then the ON CONFLICT clause 
 * specified for individual triggers steps is used.
 *
 * struct TriggerStack has a "pNext" member, to allow linked lists to be
 * constructed. When coding nested triggers (triggers fired by other triggers)
 * each nested trigger stores its parent trigger's TriggerStack as the "pNext" 
 * pointer. Once the nested trigger has been coded, the pNext value is restored
 * to the pTriggerStack member of the Parse stucture and coding of the parent
 * trigger continues.
 *
 * Before a nested trigger is coded, the linked list pointed to by the 
 * pTriggerStack is scanned to ensure that the trigger is not about to be coded
 * recursively. If this condition is detected, the nested trigger is not coded.

** If X is a character that can be used in an identifier and

** characters can be part of an identifier).  isIdChar[X] will
** be 0 for every character in the lower 128 ASCII characters
** that cannot be used as part of an identifier.
**
** In this implementation, an identifier can be a string of
** alphabetic characters, digits, and "_" plus any character
** with the high-order bit set.  The latter rule means that
** any sequence of UTF-8 characters or characters taken from
** an extended ISO8859 character set can form an identifier.

**
**   (1) NORMAL    We are in the middle of statement which ends with a single
**                 semicolon.
**
**   (2) EXPLAIN   The keyword EXPLAIN has been seen at the beginning of 
**                 a statement.
**
**   (3) CREATE    The keyword CREATE has been seen at the beginning of a
**                 statement, possibly preceeded by EXPLAIN and/or followed by
**                 TEMP or TEMPORARY
**
**   (4) TRIGGER   We are in the middle of a trigger definition that must be
**                 ended by a semicolon, the keyword END, and another semicolon.
**
**   (5) SEMI      We've seen the first semicolon in the ";END;" that occurs at
**                 the end of a trigger definition.
**
**   (6) END       We've seen the ";END" of the ";END;" that occurs at the end
**                 of a trigger difinition.
**
** Transitions between states above are determined by tokens extracted
** from the input.  The following tokens are significant:
**
**   (0) tkSEMI      A semicolon.
**   (1) tkWS        Whitespace
**   (2) tkOTHER     Any other SQL token.
**   (3) tkEXPLAIN   The "explain" keyword.
**   (4) tkCREATE    The "create" keyword.
**   (5) tkTEMP      The "temp" or "temporary" keyword.
**   (6) tkTRIGGER   The "trigger" keyword.
**   (7) tkEND       The "end" keyword.
**
** Whitespace never causes a state transition and is always ignored.
**
** If we compile with SQLITE_OMIT_TRIGGER, all of the computation needed
** to recognize the end of a trigger can be omitted.  All we have to do
** is look for a semicolon that is not part of an string or comment.

** Handling of malformed strings:
**
** SQLite accepts and processes malformed strings without an error wherever
** possible. However this is not possible when converting between UTF-8 and
** UTF-16.
**
** When converting malformed UTF-8 strings to UTF-16, one instance of the
** replacement character U+FFFD for each byte that cannot be interpeted as
** part of a valid unicode character.
**
** When converting malformed UTF-16 strings to UTF-8, one instance of the
** replacement character U+FFFD for each pair of bytes that cannot be
** interpeted as part of a valid unicode character.
**
** This file contains the following public routines:
**
** sqlite3VdbeMemTranslate() - Translate the encoding used by a Mem* string.
** sqlite3VdbeMemHandleBom() - Handle byte-order-marks in UTF16 Mem* strings.
** sqlite3utf16ByteLen()     - Calculate byte-length of a void* UTF16 string.
** sqlite3utf8CharLen()      - Calculate char-length of a char* UTF8 string.
** sqlite3utf8LikeCompare()  - Do a LIKE match given two UTF8 char* strings.

**
*************************************************************************
** The code in this file implements execution method of the 
** Virtual Database Engine (VDBE).  A separate file ("vdbeaux.c")
** handles housekeeping details such as creating and deleting
** VDBE instances.  This file is solely interested in executing
** the VDBE program.
**
** In the external interface, an "sqlite3_stmt*" is an opaque pointer
** to a VDBE.
**
** The SQL parser generates a program which is then executed by
** the VDBE to do the work of the SQL statement.  VDBE programs are 
** similar in form to assembly language.  The program consists of
** a linear sequence of operations.  Each operation has an opcode 
** and 3 operands.  Operands P1 and P2 are integers.  Operand P3 
** is a null-terminated string.   The P2 operand must be non-negative.
** Opcodes will typically ignore one or more operands.  Many opcodes
** ignore all three operands.
**
** Computation results are stored on a stack.  Each entry on the
** stack is either an integer, a null-terminated string, a floating point
** number, or the SQL "NULL" value.  An inplicit conversion from one
** type to the other occurs as necessary.
** 
** Most of the code in this file is taken up by the sqlite3VdbeExec()
** function which does the work of interpreting a VDBE program.
** But other routines are also provided to help in building up
** a program instruction by instruction.
**
** Various scripts scan this source file in order to generate HTML
** documentation, headers files, or other derived files.  The formatting
** of the code in this file is, therefore, important.  See other comments
** in this file for details.  If in doubt, do not deviate from existing
** commenting and indentation practices when changing or adding code.

**
** The formatting of each case is important.  The makefile for SQLite
** generates two C files "opcodes.h" and "opcodes.c" by scanning this

/*
** The query generator uses an array of instances of this structure to
** help it analyze the subexpressions of the WHERE clause.  Each WHERE
** clause subexpression is separated from the others by an AND operator.
**
** The idxLeft and idxRight fields are the VDBE cursor numbers for the
** table that contains the column that appears on the left-hand and
** right-hand side of ExprInfo.p.  If either side of ExprInfo.p is
** something other than a simple column reference, then idxLeft or
** idxRight are -1.  
**
** It is the VDBE cursor number is the value stored in Expr.iTable
** when Expr.op==TK_COLUMN and the value stored in SrcList.a[].iCursor.
**
** prereqLeft, prereqRight, and prereqAll record sets of cursor numbers,
** but they do so indirectly.  A single ExprMaskSet structure translates
** cursor number into bits and the translated bit is stored in the prereq
** fields.  The translation is used in order to maximize the number of
** bits that will fit in a Bitmask.  The VDBE cursor numbers might be
** spread out over the non-negative integers.  For example, the cursor
** numbers might be 3, 8, 9, 10, 20, 23, 41, and 45.  The ExprMaskSet
** translates these sparse cursor numbers into consecutive integers
** beginning with 0 in order to make the best possible use of the available
** bits in the Bitmask.  So, in the example above, the cursor numbers
** would be mapped into integers 0 through 7.
**
** prereqLeft tells us every VDBE cursor that is referenced on the
** left-hand side of ExprInfo.p.  prereqRight does the same for the
** right-hand side of the expression.  The following identity always
** holds:
**
**       prereqAll = prereqLeft | prereqRight
**
** The ExprInfo.indexable field is true if the ExprInfo.p expression
** is of a form that might control an index.  Indexable expressions
** look like this:
**
**              <column> <op> <expr>
**
** Where <column> is a simple column name and <op> is on of the operators
** that allowedOp() recognizes.

** An instance of the following structure keeps track of a mapping
** between VDBE cursor numbers and bits of the bitmasks in ExprInfo.
**
** The VDBE cursor numbers are small integers contained in 
** SrcList_item.iCursor and Expr.iTable fields.  For any given WHERE 
** clause, the cursor numbers might not begin with 0 and they might
** contain gaps in the numbering sequence.  But we want to make maximum
** use of the bits in our bitmasks.  This structure provides a mapping
** from the sparse cursor numbers into consecutive integers beginning
** with 0.
**
** If ExprMaskSet.ix[A]==B it means that The A-th bit of a Bitmask
** corresponds VDBE cursor number B.  The A-th bit of a bitmask is 1<<A.
**
** For example, if the WHERE clause expression used these VDBE
** cursors:  4, 5, 8, 29, 57, 73.  Then the  ExprMaskSet structure
** would map those cursor numbers into bits 0 through 5.
**
** Note that the mapping is not necessarily ordered.  In the example
** above, the mapping might go like this:  4->3, 5->1, 8->2, 29->0,
** 57->5, 73->4.  Or one of 719 other combinations might be used. It
** does not really matter.  What is important is that sparse cursor
** numbers all get mapped into bit numbers that begin with 0 and contain
** no gaps.

** Generate the beginning of the loop used for WHERE clause processing.
** The return value is a pointer to an opaque structure that contains
** information needed to terminate the loop.  Later, the calling routine
** should invoke sqlite3WhereEnd() with the return value of this function
** in order to complete the WHERE clause processing.
**
** If an error occurs, this routine returns NULL.
**
** The basic idea is to do a nested loop, one loop for each table in
** the FROM clause of a select.  (INSERT and UPDATE statements are the
** same as a SELECT with only a single table in the FROM clause.)  For
** example, if the SQL is this:
**
**       SELECT * FROM t1, t2, t3 WHERE ...;
**
** Then the code generated is conceptually like the following:
**
**      foreach row1 in t1 do       \    Code generated
**        foreach row2 in t2 do      |-- by sqlite3WhereBegin()
**          foreach row3 in t3 do   /
**            ...
**          end                     \    Code generated
**        end                        |-- by sqlite3WhereEnd()
**      end                         /
**
** There are Btree cursors associated with each table.  t1 uses cursor
** number pTabList->a[0].iCursor.  t2 uses the cursor pTabList->a[1].iCursor.
** And so forth.  This routine generates code to open those VDBE cursors
** and sqlite3WhereEnd() generates the code to close them.
**
** The code that sqlite3WhereBegin() generates leaves the cursors named
** in pTabList pointing at their appropriate entries.  The [...] code
** can use OP_Column and OP_Recno opcodes on these cursors to extract
** data from the various tables of the loop.
**
** If the WHERE clause is empty, the foreach loops must each scan their
** entire tables.  Thus a three-way join is an O(N^3) operation.  But if
** the tables have indices and there are terms in the WHERE clause that
** refer to those indices, a complete table scan can be avoided and the
** code will run much faster.  Most of the work of this routine is checking
** to see if there are indices that can be used to speed up the loop.
**
** Terms of the WHERE clause are also used to limit which rows actually
** make it to the "..." in the middle of the loop.  After each "foreach",
** terms of the WHERE clause that use only terms in that loop and outer
** loops are evaluated and if false a jump is made around all subsequent
** inner loops (or around the "..." if the test occurs within the inner-
** most loop)
**
** OUTER JOINS
**
** An outer join of tables t1 and t2 is conceptally coded as follows:
**
**    foreach row1 in t1 do
**      flag = 0
**      foreach row2 in t2 do
**        start:
**          ...
**          flag = 1
**      end
**      if flag==0 then
**        move the row2 cursor to a null row
**        goto start
**      fi
**    end
**
** ORDER BY CLAUSE PROCESSING
**
** *ppOrderBy is a pointer to the ORDER BY clause of a SELECT statement,
** if there is one.  If there is no ORDER BY clause or if this routine
** is called from an UPDATE or DELETE statement, then ppOrderBy is NULL.
**
** If an index can be used so that the natural output order of the table
** scan is correct for the ORDER BY clause, then that index is used and
** *ppOrderBy is set to NULL.  This is an optimization that prevents an
** unnecessary sort of the result set if an index appropriate for the
** ORDER BY clause already exists.
**
** If the where clause loops cannot be arranged to provide the correct
** output order, then the *ppOrderBy is unchanged.

    The goal of this version of close is different than that of sqlite3_close(), and is designed to lend itself better to .NET's non-deterministic finalizers and
    the GC thread.  SQLite will not close a database if statements are open on it -- but for our purposes, we'd rather finalize all active statements
    and forcibly close the database.  The reason is simple -- a lot of people don't Dispose() of their objects correctly and let the garbage collector
    do it.  This leads to unexpected behavior when a user thinks they've closed a database, but it's still open because not all the statements have
    hit the GC yet.

    So, here we have a problem ... .NET has a pointer to any number of sqlite3_stmt objects.  We can't call sqlite3_finalize() on these because
    their memory is freed and can be used for something else.  The GC thread could potentially try and call finalize again on the statement after
    that memory was deallocated.  BAD.  So, what we need to do is make a copy of each statement, and call finalize() on the copy -- so that the original
    statement's memory is preserved, and marked as BAD, but we can still manage to finalize everything and forcibly close the database.  Later when the 
    GC gets around to calling finalize_interop() on the "bad" statement, we detect that and finish deallocating the pointer.

        HACK: *UNCONDITIONAL* The Visual Studio IDE ignores the
              BaseIntermediateOutputPath property and creates empty "bin" and
              "obj" directories for every project whenever the project is opened
              or built.  Also, the Visual Studio IDE will occasionally fail to
              rebuild the project due to this confusion.  The situation appears
              to improve somewhat when this is set to false.  Please note that
              even if this is set to false, things still do not work 100%
              correctly; however, at least there appears to be less build
              failures.

              Please see Microsoft Connect FeedbackID 105854 for their official
              list of excuses, on this now more than 3 year old bug.

  <!-- 
    Microsoft ResX Schema 
    
    Version 2.0
    
    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.
    
    Example:
    
    ... ado.net/XML headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">2.0</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
        <value>[base64 mime encoded serialized .NET Framework object]</value>
    </data>
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
        <comment>This is a comment</comment>
    </data>
                
    There are any number of "resheader" rows that contain simple 
    name/value pairs.
    
    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.
    
    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:
    
    Note - application/x-microsoft.net.object.binary.base64 is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.
    
    mimetype: application/x-microsoft.net.object.binary.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.
    
    mimetype: application/x-microsoft.net.object.soap.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.bytearray.base64
    value   : The object must be serialized into a byte array 
            : using a System.ComponentModel.TypeConverter
            : and then encoded with base64 encoding.

  /// Translates the command object into a SQL string that can be executed on

  /// <remarks>
  /// The translation is implemented as a visitor <see cref="DbExpressionVisitor{T}"/>
  /// over the query tree.  It makes a single pass over the tree, collecting the sql
  /// fragments for the various nodes in the tree <see cref="ISqlFragment"/>.
  ///
  /// The major operations are
  /// <list type="bullet">
  /// <item>Select statement minimization.  Multiple nodes in the query tree
  /// that can be part of a single SQL select statement are merged. e.g. a
  /// Filter node that is the input of a Project node can typically share the
  /// same SQL statement.</item>
  /// <item>Alpha-renaming.  As a result of the statement minimization above, there
  /// could be name collisions when using correlated subqueries
  /// <example>
  /// <code>
  /// Filter(
  ///     b = Project( c.x
  ///         c = Extent(foo)
  ///         )
  ///     exists (
  ///         Filter(
  ///             c = Extent(foo)
  ///             b.x = c.x
  ///             )
  ///     )
  /// )
  /// </code>
  /// The first Filter, Project and Extent will share the same SQL select statement.
  /// The alias for the Project i.e. b, will be replaced with c.
  /// If the alias c for the Filter within the exists clause is not renamed,
  /// we will get <c>c.x = c.x</c>, which is incorrect.
  /// Instead, the alias c within the second filter should be renamed to c1, to give
  /// <c>c.x = c1.x</c> i.e. b is renamed to c, and c is renamed to c1.
  /// </example>
  /// </item>
  /// <item>Join flattening.  In the query tree, a list of join nodes is typically
  /// represented as a tree of Join nodes, each with 2 children. e.g.
  /// <example>
  /// <code>
  /// a = Join(InnerJoin
  ///     b = Join(CrossJoin
  ///         c = Extent(foo)
  ///         d = Extent(foo)
  ///         )
  ///     e = Extent(foo)
  ///     on b.c.x = e.x
  ///     )
  /// </code>
  /// If translated directly, this will be translated to
  /// <code>
  /// FROM ( SELECT c.*, d.*
  ///         FROM foo as c
  ///         CROSS JOIN foo as d) as b
  /// INNER JOIN foo as e on b.x' = e.x
  /// </code>
  /// It would be better to translate this as
  /// <code>
  /// FROM foo as c
  /// CROSS JOIN foo as d
  /// INNER JOIN foo as e on c.x = e.x
  /// </code>
  /// This allows the optimizer to choose an appropriate join ordering for evaluation.
  /// </example>
  /// </item>
  /// <item>Select * and column renaming.  In the example above, we noticed that
  /// in some cases we add <c>SELECT * FROM ...</c> to complete the SQL
  /// statement. i.e. there is no explicit PROJECT list.
  /// In this case, we enumerate all the columns available in the FROM clause
  /// This is particularly problematic in the case of Join trees, since the columns
  /// from the extents joined might have the same name - this is illegal.  To solve
  /// this problem, we will have to rename columns if they are part of a SELECT *
  /// for a JOIN node - we do not need renaming in any other situation.

  /// <summary>
  /// A SqlSelectStatement represents a canonical SQL SELECT statement.
  /// It has fields for the 5 main clauses
  /// <list type="number">
  /// <item>SELECT</item>
  /// <item>FROM</item>
  /// <item>WHERE</item>
  /// <item>GROUP BY</item>
  /// <item>ORDER BY</item>
  /// </list>
  /// We do not have HAVING, since it does not correspond to anything in the DbCommandTree.
  /// Each of the fields is a SqlBuilder, so we can keep appending SQL strings
  /// or other fragments to build up the clause.
  ///
  /// We have a IsDistinct property to indicate that we want distict columns.
  /// This is given out of band, since the input expression to the select clause
  /// may already have some columns projected out, and we use append-only SqlBuilders.
  /// The DISTINCT is inserted when we finally write the object into a string.
  /// 
  /// Also, we have a Top property, which is non-null if the number of results should
  /// be limited to certain number. It is given out of band for the same reasons as DISTINCT.
  ///
  /// The FromExtents contains the list of inputs in use for the select statement.
  /// There is usually just one element in this - Select statements for joins may
  /// temporarily have more than one.

    Microsoft ResX Schema 
    
    Version 2.0
    
    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.
    
    Example:
    
    ... ado.net/XML headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">2.0</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
        <value>[base64 mime encoded serialized .NET Framework object]</value>
    </data>
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
        <comment>This is a comment</comment>
    </data>
                
    There are any number of "resheader" rows that contain simple 
    name/value pairs.
    
    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.
    
    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:
    
    Note - application/x-microsoft.net.object.binary.base64 is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.
    
    mimetype: application/x-microsoft.net.object.binary.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.
    
    mimetype: application/x-microsoft.net.object.soap.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.bytearray.base64
    value   : The object must be serialized into a byte array 
            : using a System.ComponentModel.TypeConverter
            : and then encoded with base64 encoding.

ADO.NET SQLite Data Provider<br />
Version 1.0.77.0 November 28, 2011<br />
Using SQLite 3.7.9 <a href="http://www.sqlite.org/src/info/c7c6050ef0">[c7c6050ef0]</a><br />
Originally written by Robert Simpson<br />
Released to the public domain, use at your own risk!<br />
Official provider website:&nbsp; <a href="http://system.data.sqlite.org/">http://system.data.sqlite.org/</a><br />
Legacy versions:&nbsp; <a href="http://sqlite.phxsoftware.com/">http://sqlite.phxsoftware.com/</a><br />
<br />
The current development version can be downloaded from <a href="http://system.data.sqlite.org/index.html/timeline?n=20&y=ci">
http://system.data.sqlite.org/index.html/timeline?n=20&y=ci</a>

<br />
<br />

<h2><b>Features</b></h2>

<ul>
  <li>
    Written from scratch on Visual Studio 2008 specifically for ADO.NET,
    implementing all the base classes and features recently introduced in the
    framework, including automatic transaction enlistment.
  </li>

  <li>
    Supports the Full and Compact .NET Framework, and native C/C++ development.
    100% binary compatible with the original sqlite3.dll.
  </li>

  <li>
    Full support for Mono via a &quot;managed only&quot; provider that runs
    against the official SQLite 3.6.1 or higher library.
  </li>

  <li>Full Entity Framework support (ADO.NET 3.5 SP1).</li>

  <li>
    On the Compact Framework, it is faster than SQL Server Mobile.  SQLite's
    installed size is a fraction of SQL Mobile's.  It uses less memory at
    runtime, runs queries faster, and has a smaller database file size as well.
  </li>

  <li>
    Encrypted database support.  Encrypted databases are fully encrypted and
    support both binary and cleartext password types.
  </li>

  <li>
    Visual Studio design-time Support, works with all versions of Visual Studio
    2005/2008/2010.  You can add a SQLite database to the Servers list, design
    queries with the Query Designer, drag-and-drop tables onto a Typed DataSet,
    etc.
    <br />
    <font color="red">
      Currently not included.  We are still updating the design-time support
      installer.  Due to Visual Studio licensing restrictions, the Express
      Editions can no longer be supported.
    </font>
  </li>

  <li>
    Full SQLite schema editing inside Visual Studio.  You can create/edit tables,
    views, triggers, indexes, check constraints and foreign keys.
  </li>

  <li>
    Single file redistributable (except on Compact Framework).  The core SQLite
    native code and the ADO.NET managed wrapper are combined into one mixed-mode
    assembly.
  </li>

  <li>
    Binaries included for x86, x64, Itanium, and ARM processors.
    <br />
    <font color="red">
      Itanium processor support not currently included.
    </font>
  </li>



  <li>DbProviderFactory support.</li>

  <li>
    Full support for ATTACH'ed databases.  Exposed as <i>Catalogs</i> in the
    schema.  When cloning a connection, all attached databases are automatically
    re-attached to the new connection.
  </li>

  <li>
    DbConnection.GetSchema(...) support includes <i>ReservedWords</i>,
    <i>MetaDataCollections</i>, <i>DataSourceInformation</i>, <i>DataTypes</i>,
    <i>Columns</i>, <i>Tables</i>, <i>Views</i>, <i>ViewColumns</i>,
    <i>Catalogs</i>, <i>Indexes</i>, <i>IndexColumns</i>, <i>ForeignKeys</i> and
    <i>Triggers</i>.
  </li>

  <li>
    Enhanced DbDataReader.GetSchemaTable() functionality returns catalog,
    namespace and detailed schema information even for complex queries.
  </li>

  <li>Named and unnamed parameters.</li>

  <li>
    Full UTF-8 and UTF-16 support, each with optimized pipelines into the native
    database core.
  </li>

  <li>
    Multiple simultaneous DataReaders (one DataReader per Command however).
  </li>

  <li>
    Full support for user-defined scalar and aggregate functions, encapsulated

    into an easy-to-use base class in which only a couple of overrides are
    necessary to implement new SQL functions.
  </li>

  <li>
    Full support for user-defined collating sequences, every bit as simple to
    implement as user-defined functions and uses the same base class.
  </li>

  <li>
    Full source for the entire engine and wrapper.  No copyrights.  Public
    Domain.  100% free for commercial and non-commercial use.
  </li>
</ul>

<h2><strong>Design-Time Support</strong></h2>
<font color="red">Currently not included.  We are still updating the Design-Time
support installer.</font>
<p>
In Windows Explorer, navigate to the <strong>SQLite.NET\bin\Designer</strong> folder
and execute the <strong>INSTALL.EXE</strong> file.&nbsp; The program will automatically
detect what version(s) of Visual Studio 2005/2008 are installed and allow you to
selectively install and uninstall the designer for each edition.</p>
<h2>
<strong>DbFactory Support (Non-Compact Framework)</strong></h2>
In order to use the SQLiteFactory and have the SQLite data provider enumerated in
the DbProviderFactories methods, you must add the following segment into your application's


app.config file:<br />
<pre>
&lt;configuration&gt;
    &lt;system.data&gt;
        &lt;DbProviderFactories&gt;
            &lt;remove invariant="System.Data.SQLite" /&gt;
            &lt;add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".Net Framework Data Provider for SQLite"
                 type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" /&gt;
        &lt;/DbProviderFactories&gt;
    &lt;/system.data&gt;
&lt;/configuration&gt;
</pre>
<p>
See the help documentation for further details on implementing both version-specific
(GAC enabled) and version independent DBProviderFactories support.
</p>

<h2>Compiling for the Compact Framework</h2>

<p>
Just change the target platform from Win32 to Compact Framework and recompile.&nbsp;
<strong>The Compact Framework has no support for enumerating attributes in an assembly,
therefore all user-defined collating sequences and functions must be explicitly
registered.</strong>&nbsp; See the <strong>testce</strong> sample application for
an example of how to explicitly register user-defined collating sequences and functions.</p>

<h2><b><a name="redist"></a>Distributing The SQLite Engine and ADO.NET Assembly</b></h2>

<p>
On the desktop, only the <strong>System.Data.SQLite.DLL</strong> file needs to be
distributed with your application(s).&nbsp; This DLL contains both the managed wrapper
and the native SQLite3 codebase.&nbsp; For the Compact Framework, you will have
to distribute both the CF version of System.Data.SQLite.DLL, as well as the SQLite.Interop.XXX.DLL.&nbsp;
This is a breaking change as of 1.0.59.0.&nbsp; Recent Windows Mobile frameworks
are not supporting the mixed CF assembly I was building prior to this version.</p>

<h2><b>Development Notes Regarding the SQLite 3 Source Code</b></h2>

<p>
The core SQLite engine is compiled directly from the unmodified source code available
at the sqlite.org website.&nbsp; Several additional pieces are compiled on top of
it to extend its functionality, but the core engine's source is not changed.</p>
<p>
</p>

<h2><b>Version History</b></h2>

<p>
    <b>1.0.77.0 - November 28, 2011</b>
</p>
<ul>
    <li>Updated to SQLite 3.7.9 <a href="http://www.sqlite.org/src/info/a499ae3835">[a499ae3835]</a>.</li>
    <li>More enhancements to the build and test automation.</li>
    <li>Plug native memory leak when closing a database connection containing a statement that cannot be finalized for some reason.</li>
    <li>The SQLite3 class should always attempt to dispose the contained SQLiteConnectionHandle, even when called via the finalizer.</li>
    <li>When compiled with DEBUG defined, emit diagnostic information related to resource cleanup to any TraceListener objects that may be registered.</li>
    <li>Stop characterizing all log messages as errors. From now on, if the errorCode is zero, the message will not be considered an error.</li>
    <li>Never attempt to configure the native logging interface if the SQLite core library has already been initialized for the process. Fix for [2ce0870fad].</li>
    <li>Allow the SQLiteLog class to be used for logging messages without having an open connection.</li>
    <li>Support building the core System.Data.SQLite assemblies using the .NET Framework 4.0 Client Profile. Fix for [566f1ad1e4].</li>
    <li>When generating the schema based on the contents of a SQLiteDataReader, skip flagging columns as unique if the data reader is holding the result of some kind of multi-table construct (e.g. a cross join) because we must allow duplicate values in that case. Fix for [7e3fa93744].</li>
    <li>When returning schema information that may be used by the .NET Framework to construct dynamic SQL, use a fake schema name (instead of null) so that the table names will be properly qualified with the catalog name (i.e. the attached database name). Partial fix for [343d392b51].</li>
    <li>Add SQLiteSourceId property to the SQLiteConnection class to return the SQLite source identifier.</li>
    <li>Add MemoryUsed and MemoryHighwater properties to the SQLiteConnection class to help determine the memory usage of SQLite.</li>
    <li>Add DateTimeKind connection string property to control the DateTimeKind of parsed DateTime values. Partial fix for [343d392b51].</li>
    <li>Improve the robustness of the SQLiteLog class when it will be initialized and unloaded multiple times.</li>
    <li>Fix the name of the interop assembly for Windows CE. Add unit tests to prevent this type of issue from happening again. Fix for [737ca4ff74].</li>
    <li>Formally support the SQL type name BOOLEAN in addition to BOOL. Fix for [544dba0a2f].</li>
    <li>Make sure the SQLiteConvert.TypeNameToDbType method is thread-safe. Fix for [84718e79fa].</li>
</ul>
<p>
    <b>1.0.76.0 - October 4, 2011</b>
</p>
<ul>
    <li>Prevent the domain unload event handler in SQLiteLog from being registered multiple times. Fix for [0d5b1ef362].</li>

</p>
<ul>
    <li>Updated to SQLite 3.7.8 <a href="http://www.sqlite.org/src/info/3e0da808d2">[3e0da808d2]</a>.</li>

    <li>Add official <a href="http://www.nuget.org/">NuGet</a> packages for x86 and x64.</li>
    <li>Add Changes and LastInsertRowId properties to the connection class.</li>
    <li>Support more formats when converting data from/to the DateTime type.</li>
    <li>Make all the assembly versioning attributes consistent.</li>
    <li>Add unit testing infrastructure using <a href="http://eagle.to/">Eagle</a>.</li>
    <li>Integrate all legacy unit tests, including the &quot;testlinq&quot; project, into the new test suite.</li>
    <li>Add projects to build the interop assembly statically linked to the Visual C++ runtime. Fix for [53f0c5cbf6].</li>
    <li>Add SQLITE_ENABLE_STAT2 compile-time option to the interop assembly.  Fix for [74807fbf27].</li>
    <li>Fix mutex issues exposed when running the test suite with the debug version of SQLite.</li>
    <li>Fix transaction enlistment when repeated attempts are made to enlist in the same transaction. Fix for [ccfa69fc32].</li>
    <li>Support the SQLITE_FCNTL_WIN32_AV_RETRY file control to mitigate the impact of file sharing violations caused by external processes.</li>
    <li>Refactor the logging interface to be thread-safe and self-initializing.</li>
    <li>Shutdown the SQLite native interface when the AppDomain is being unloaded. Fix for [b4a7ddc83f].</li>

<ul>
<li>Fixed the missing resources problem from the 63 release.</li>
<li>Added preliminary support for the Visual Studio 2010 beta.</li>
<li>Fixed a bug in SQLiteCommand that threw a null reference exception when setting
the Transaction object to null.</li>
<li>If SQLiteConnection.EnlistTransaction is called multiple times for the same
transaction scope, just return without throwing an error.</li>
</ul>
<p>
<b>1.0.63.0 - June 29, 2009</b></p>
<ul>
<li>Code merge with SQLite 3.6.16</li>
<li>Check the autocommit mode of the connection to which a transaction is bound
during the disposal of the transaction.&nbsp; If autocommit is enabled, then the
database has already rolled back the transaction and we don&#39;t need to do it
during dispose, and can quietly ignore the step without throwing an error.</li>
<li>Eliminated the mergebin step altogether.&nbsp; It was developed primarily to
merge the Compact Framework binaries together, but since we&#39;re not doing that
anymore, its use is limited.&nbsp; Its non-standard method of merging a binary on
the desktop framework is redundant as well.&nbsp; The desktop binary now hard-links
to MSCOREE, but as of Windows XP, this was redundant as well since XP and beyond
automatically attempt to load MSCOREE on startup when a DLL has a .NET header.</li>
<li>More improvements to the test.exe program for running the tests against Sql
Server for comparison purposes.</li>

message pumping</li>
<li>Fixed a bad pointer conversion when retrieving blobs using GetBytes() in 64-bit
land</li>
<li>Several changes to the Test program that comes with the provider.&nbsp; Tests
can now be individually disabled, and the test program can run against several provider
back-ends</li>
</ul>
<p>
<b>1.0.61.0 - April 28, 2009</b></p>
<ul>
<li>Code merge with SQLite 3.6.13. The new backup features are as yet unimplemented
in the provider, but will be forthcoming in a subsequent release</li>
<li>Fixed the default-value lookups in SQLiteConnectionStringBuilder when accessing
properties</li>
<li>Lock the SQLiteTransaction object during dispose to avoid potential race condition
during cleanup</li>
<li>Fixed SQLiteDataReader.GetDecimal() processing and parsing of decimal values
for cases when SQLite returns things like "1.0e-05" instead of "0.0001"</li>
</ul>
<p>
<b>1.0.60.0 - October 3, 2008</b></p>
<ul>
<li>Throw a NotSupported exception in the EF Sql Gen code instead of parsing illegal
SQL during an update/insert/delete where no primary key is defined.</li>
<li>Fixed the Compact Framework interop library.&nbsp; Since the linker flag /subsystem
had no version specified, it was causing a problem for many CE-based platforms.</li>
<li>Incorporated SQLite patch for ticket <a href="http://www.sqlite.org/cvstrac/tktview?tn=3387">
#3387</a> and reverted out the vfs override code I added in build 59 to work around
this problem.</li>
<li>Fixed a designer issue when creating a new table from the Server Explorer.&nbsp;
After initially saving it, if you then continued to edit it and tried to save it
again, it would generate the change SQL using the old temporary table name rather
than the new name.</li>
</ul>
<p>
<b>1.0.59.0 - September 22, 2008</b></p>
<ul>
<li>Code merge with SQLite 3.6.3.&nbsp; Solves a couple different EF issues that
were either giving inconsistent results or crashing the engine.</li>
<li>Fixed the parsing of literal binaries in the EF SqlGen code.&nbsp; SQLite now
passes nearly all the testcases in <a href="http://sqlite.phxsoftware.com/forums/p/1377/5921.aspx#5921">
Microsoft's EF Query Samples</a> application -- the exception being the <i>datetimeoffset
</i>and<i> time</i> constants tests, and tests that use the <i>APPLY </i>keyword
which are unsupported for now.</li>
<li>Revamped the Compact Framework mixed-mode assembly.&nbsp; Tired of playing cat
and mouse with the Compact Framework&#39;s support for mixed-mode assemblies.&nbsp;
The CF build now requires that you distribute both the System.Data.SQLite library
and the paired SQLite.Interop.XXX library.&nbsp;&nbsp; The XXX denotes the build
number of the library.</li>
<li>Implemented a workaround for Vista&#39;s overzealous caching by turning off
FILE_FLAG_RANDOM_ACCESS for OS versions above XP.&nbsp; This is implemented as a
custom (default override) VFS in the interop.c file, so no changes are made to the
SQLite source code.</li>
<li>Fixed some registry issues in the designer install.exe, which prevented some
design-time stuff from working on the Compact Framework when .NET 3.5 was installed.</li>
</ul>
<p>
<b>1.0.58.0 - August 30, 2008</b></p>
<ul>
<li>Code merge with SQLite 3.6.2.&nbsp; If only I&#39;d waited one more day to release
57!&nbsp; Several LINQ issues have been resolved with this engine release relating
to deeply-nested subqueries that the EF SqlGen creates.</li>
<li>The Rollback SQLiteConnection event no longer requires an open connection in
order to subscribe to it.&nbsp; Missed this one in the 57 release.</li>
</ul>
<p>
<b>1.0.57.0 - August 29, 2008</b></p>
<ul>
<li>Compiled against 3.6.1 with checkin <a href="http://www.sqlite.org/cvstrac/tktview?tn=3300">
#3300</a> resolved, which fixes an Entity Framework bug I was seeing.&nbsp; I currently
have 3 other tickets out on the engine, which are not yet resolved and relate to
EF.</li>
<li>Fixed decimal types to store and fetch using InvariantCulture.&nbsp; If you&#39;re
using decimal datatypes in your database and were affected by the 56 release, please
issue an UPDATE &lt;table&gt; SET &lt;column&gt; = REPLACE(&lt;column&gt;, &#39;,&#39;,
&#39;.&#39;);&nbsp; to fix the decimal separators.&nbsp; Apologies for not testing
that more thoroughly before releasing 56.</li>
<li>Too many LINQ fixes to list.&nbsp; Fixed views so they generate, fixed the LIMIT
clause, implemented additional functionality and removed unnecessary code.</li>
<li>Fixed foreign key names in the designer so viewing the SQL script on a new unsaved
table after renaming it in the properties toolwindow will reflect in the script
properly.</li>
<li>Fixed the Update and Commit events on SQLiteConnection so they don&#39;t require
the connection to be opened first.</li>
<li>Fixed userdef aggregate functions so they play nice with each other when appearing
multiple times in the same statement.</li>
<li>Fixed the editing and saving of default values in the table designer.</li>
<li>Fixed ForeignKeys schema to support multi-column foreign keys.&nbsp; Also hacked
support for them in the table designer, provided two foreign keys in the designer
have the same name and reference the same foreign table and different columns.&nbsp;
Will implement first-class support for this in the next release.</li>
</ul>
<p>
<b>1.0.56.0 - August 11, 2008</b></p>
<ul>
<li>Fixed a bug in the table designer when designing new tables, wherein you had
to save the table first before being able to create indexes and foreign keys.</li>
<li>Tweaks to decimal type handling.&nbsp; The &#39;decimal&#39; type can&#39;t
be represented by Int64 or Double (without loss of precision) in SQLite, so we have
to fudge it by treating it like a string and converting it back and forth in the
provider.&nbsp; Unfortunately backing it to the db as a string causes sorting problems.&nbsp;
See <a href="http://sqlite.phxsoftware.com/forums/p/1296/5595.aspx#5595">this post</a>
for details on using a custom collation sequence to overcome the sorting issue arising
from this patch.</li>
<li>Minor tweaks and bugfixes to the test program and the provider.</li>
<li>More adjustments to make the managed-only version of the provider run and pass
all tests on Mono.</li>
<li>LINQ to Entities bits heavily updated and compiled against VS2008 SP1 RTM.&nbsp;
SQLite LINQ support is still considered beta.</li>
</ul>
<p>
<b>1.0.55.0 - August 6, 2008</b></p>
<ul>
<li>Code merge with SQLite 3.6.1</li>
<li>Added support for the user-contributed extension-functions at <a href="http://www.sqlite.org/contrib">
http://www.sqlite.org/contrib</a>.&nbsp; Feel free to override any of them with
your own implementation.&nbsp; The new functions are: <i>acos, asin, atan, atn2,
atan2, acosh, asinh, atanh, difference, degrees, radians, cos, sin, tan, cot, cosh,
sinh, tanh, coth, exp, log, log10, power, sign, sqrt, square, ceil, floor, pi, replicate,
charindex, leftstr, rightstr, reverse, proper, padl, padr, padc, strfilter,</i>
and aggregates <i>stdev, variance, mode, median, lower_quartile, upper_quartile.</i></li>
<li>Moved the last_rows_affected() function to the C extension library.</li>
<li>Added a new class, SQLiteFunctionEx which extends SQLiteFunction and adds the
ability for a user-defined function to get the collating sequence during the Invoke/Step
methods.&nbsp; User-defined functions can use the collating sequence as a helper
to compare values.</li>
<li>When registering user-defined collation sequences and functions, the provider
will now register both a UTF8 and a UTF16 version instead of just UTF8.</li>
<li>Revamped connection pooling and added static ClearPool() and ClearAllPools()
functions to SQLiteConnection.&nbsp; Behavior of the pool and its clearing mechanics
match SqlClient.</li>
<li>Fixed connections going to the pool so that any unfinalized lingering commands
from un-collected datareaders are automatically reset and any lurking transactions
made on the connection are rolled back.</li>
<li>Transaction isolation levels are now partially supported.&nbsp; Serializable
is the default, which obtains read/write locks immediately -- this is compatible
with previous releases of the provider.&nbsp; Unspecified will default to whatever
the default isolation mode is set to, and ReadCommitted will cause a deferred lock
to be obtained.&nbsp; No other values are legal.</li>
<li>Revamped the test.exe program.&nbsp; It&#39;s now an interactive GUI application.&nbsp;
Easier for me to add tests now.</li>
<li>Tweaks to the VS designer package and installer.</li>
<li>More adjustments to the internal SQLite3.Prepare() method to account for both
kinds of lock errors when retrying.</li>
<li>Stripped a lot of unnecessary interop() calls and replaced with base sqlite
calls.&nbsp; Revamped most of UnsafeNativeMethods to make it easier to port the
code.</li>
<li>Rerigged internal callbacks for userdef functions and other native to managed
callbacks.&nbsp; More portable this way.</li>
<li>Source can now can be compiled with the SQLITE_STANDARD preprocessor symbol
to force the wrapper to use the stock sqlite3 library.&nbsp; Some functionality
is missing, but its minimal.&nbsp; None of the precompiled binaries are compiled
using this setting, but its useful for testing portability.</li>
<li>Added &quot;boolean&quot; and a couple other missing datatypes to the &quot;DataTypes&quot;
schema xml file.&nbsp; Used by the VS designer when displaying tables and querying.</li>
<li>Added a new connection string option &quot;Read Only&quot;.&nbsp; When set to
True, the database will be opened in read-only mode.</li>
<li>Added a new connection string option &quot;Max Pool Size&quot; to set the maximum
size of the connection pool for a given db file connection.</li>
<li>Added a new connection string option &quot;Default IsolationLevel&quot; to set
the default isolation level of transactions.&nbsp; Possible values are Serializable
and ReadCommitted.</li>
<li>Added a new connection string option &quot;URI&quot; as an optional parameter
for compatibility with other ports of the provider.</li>
</ul>
<p>
<b>1.0.54.0 - July 25, 2008</b></p>
<ul>
<li>Fixed the setup project, which somehow &quot;forgot&quot; to include all the
binaries in the 53 release.</li>
<li>Fixed a crash in the table designer when creating a new table and tabbing past
the &quot;Allow Nulls&quot; cell in the grid while creating a new column.</li>
<li>Fixed a mostly-benign bug in SQLiteDataReader&#39;s GetEnumerator, which failed
to pass along a flag to the underyling DbEnumerator it creates.&nbsp; This one&#39;s
been around since day 1 and nobody&#39;s noticed it in all these years.</li>
<li>Added a new connection string parameter &quot;Journal Mode&quot; that allows
you to set the SQLite journal mode to Delete, Persist or Off.</li>
</ul>
<p>
<b>1.0.53.0 - July 24, 2008</b></p>
<ul>
<li>Enabled sqlite_load_extension</li>
<li>Added retry/timeout code to SQLite3.Prepare() when preparing statements for
execution and a SQLITE_BUSY error occurs.</li>
<li>Added a new schema to SQLiteConnection.GetSchema() called <i>Triggers</i>.&nbsp;
Used to retrieve the trigger(s) associated with a database and/or table/view.</li>
<li>Extensive updates to table/view editing capabilities inside Visual Studio&#39;s
Server Explorer.&nbsp; The program now parses and lets you edit CHECK constraints
and triggers on a table, as well as define triggers on views.&nbsp; Experimental
still, so e-mail me if you have issues.</li>
<li>Minor bugfix to the ViewColumns schema to return the proper base column name
for a view that aliases a column.</li>
<li>Fixed the insert/update/delete DML support in the Linq module.</li>
<li>Changed the behavior of SQLiteCommand to allow a transaction to be set even
if the command hasn&#39;t been associated with a connection yet.</li>
</ul>
<p>
<b>1.0.52.0 - July 16, 2008</b></p>
<ul>
<li>Code merge with SQLite 3.6.0</li>
<li>Added a lot of previously-missing exports to the DEF file for the native library.</li>
<li>Fixed SQLiteDataReader to check for an invalid connection before operating on
an open cursor.</li>
<li>Implemented the Cancel() function of SQLiteCommand to cancel an active reader.</li>
<li>Added beta table and view designers to the Visual Studio Server Explorer.&nbsp;
You can now edit/create tables and views, manage indexes and foreign keys from Visual
Studio.&nbsp; This feature is still undergoing testing so use at your own risk!</li>
<li>Fixed the Server Explorer so VS2005 users can once again right-click tables
and views and open the table data.</li>
<li>Added some new interop code to assist in returning more metadata not normally
available through the SQLite API.&nbsp; Specifically, index column sort modes and
collating sequences.&nbsp; Also added code to detect (but not parse) CHECK constraints,
so the table designer can pop up a warning when editing a table with these constraints.&nbsp;
Since I can&#39;t currently parse them.</li>
<li>Lots of LINQ SQL generation improvements and fixes.</li>
<li>Made some progress cleaning up and fixing up the schema definitions and manifests
for EdmGen.</li>
<li>Added a built-in SQLiteFunction called last_rows_affected() which can be called
from SQL to get the number of rows affected by the last update/insert operation
on the connection.&nbsp; This is roughly equivalent to Sql Server&#39;s @@ROWCOUNT
variable.</li>
</ul>
<p>
<b>1.0.51.0 - July 1, 2008</b></p>
<ul>
<li><b>VS2008 SP1 Beta1 LINQ Support</b></li>
<li>Added experimental Entity Framework support in a new library, System.Data.SQLite.Linq.&nbsp;
Some things work, some don&#39;t.&nbsp; I haven&#39;t finished rigging everything
up yet.&nbsp; The core library remains stable.&nbsp; All LINQ-specific code is completely
separate from the core.</li>
<li>Added some columns to several existing schemas to support some of the EDM framework
stuff.</li>
<li>Minor tweaks to the factory to better support dynamic loading of the Linq extension
library for SQLite.</li>
<li>SQLite&#39;s busy handler was interfering with the provider&#39;s busy handling
mechanism, so its been disabled.</li>
</ul>
<p>
<b>1.0.50.0 - June 27, 2008</b></p>
<ul>
<li>Fixed some lingering dispose issues and race conditions when some objects were
finalized.</li>
<li>Fixed the SQLiteConvert.Split() routine to be a little smarter when splitting
strings, which solves the quoted data source filename problem.</li>
<li>Enhanced the mergebin utility to work around the strong name validation bug
on the Compact Framework.&nbsp; The old workaround kludged the DLL and caused WM6.1
to fail to load it.&nbsp; This new solution is permanent and no longer kludges the
DLL.</li>
</ul>
<p>
<b>1.0.49.0 - May 28, 2008</b></p>
<ul>
<li>Code merge with SQLite 3.5.9</li>
<li>Fixed schema problems when querying the TEMP catalog.</li>
<li>Changed BLOB datatype schema to return IsLong = False instead of True.&nbsp;
This was preventing DbCommandBuilder from using GUID's and BLOB's as primary keys.</li>
<li>Fix rollover issue with SQLite3.Reset() using TickCount.</li>
<li>Fixed SQLiteDataReader to dispose of its command (if called for) before closing
the connection (when flagged to do so) instead of the other way around.</li>
<li>Fixed a DbNull error when retrieving items not backed by a table schema.</li>
<li>Fixed foreign key constraint parsing bug.</li>
<li>Added FailIfMissing property to the SQLiteConnectionStringBuilder.</li>
<li>Converted the source projects to Visual Studio 2008.</li>
</ul>
<p>
<b>1.0.48.0 - December 28, 2007</b></p>
<ul>
<li>Code merge with SQLite 3.5.4</li>
<li>Calling SQLiteDataReader.GetFieldType() on a column with no schema information
and whos first row is initially NULL now returns type Object instead of type DbNull.</li>
<li>Added support for a new DateTime type, JulianDay.&nbsp; SQLite uses Julian dates
internally.</li>
<li>Added a new connection string parameter "Default Timeout" and a corresponding
method on the SQLiteConnection object to change the default command timeout.&nbsp;
This is especially useful for changing the timeout on transactions, which use SQLiteCommand
objects internally and have no ADO.NET-friendly way to adjust the command timeout
on those commands.</li>
<li>FTS1 and FTS2 modules were removed from the codebase.&nbsp; Please upgrade all
full-text indexes to use the FTS3 module.&nbsp;</li>
</ul>
<p>
<b>1.0.47.2 - December 10, 2007</b></p>
<ul>
<li>Fixed yet one more bug when closing a database with unfinalized command objects</li>
<li>Fixed the DataReader's GetFieldType function when dealing with untyped SQLite
affinities</li>
</ul>
<p>
<b>1.0.47.1 - December 5, 2007</b></p>
<ul>
<li>Fixed a leftover bug from the codemerge with SQLite 3.5.3 that failed to close
a database.</li>
<li>Fixed the broken Compact Framework distribution binary.</li>
<li>SQLite 3.5.x changed some internal infrastructure pieces in the encryption interface
which I didn't catch initially.&nbsp; Fixed.&nbsp;</li>
</ul>
<p>
<b>1.0.47.0 - December 4, 2007</b></p>
<ul>
<li>Code merge with SQLite 3.5.3</li>
<li>Added installer support for Visual Studio 2008.&nbsp; Code is still using the
VS2005 SDK so one or two bells and whistles are missing, but nothing significant.</li>
<li>This is the last version that the FTS1 and FTS2 extensions will appear.&nbsp;
Everyone should rebuild their fulltext indexes using the new FTS3 module.&nbsp;
FTS1 and FTS2 suffer from a design flaw that could cause database corruption with
certain vacuum operations.</li>
<li>Fixed pooled connections so they rollback any outstanding transactions before
going to the pool.&nbsp; </li>
<li>Fixed the unintended breaking of the TYPES keyword, and mis-typing of untyped
or indeterminate column types. </li>
<li>Assert a FileIOPermission() requirement in the static SQLiteFunction constructor.
</li>
<li>The CE-only SQLiteFunction.RegisterFunction() is now available on the desktop
platform for dynamic registration of functions.&nbsp; You must still close and re-open
a connection in order for the new function to be seen by a connection.</li>
<li>Fixed the "database is locked" errors by implementing behavioral changes in
the interop.c file for SQLite.&nbsp; Closing a database force-finalizes any prepared
statements on the database to ensure the connection is fully closed.&nbsp; This
was rather tricky because the GC thread could still be finalizing statements itself.
&nbsp;</li>
<li>Modifed the mergebin utility to help circumvent a long-standing strong name
verification bug in the Compact Framework.</li>
</ul>
<p>
<b>1.0.46.0 - September 30, 2007</b></p>
<ul>
<li>Fixed faulty logic in type discovery code when using SQLiteDataReader.GetValue().</li>
<li>Fixed Connection.Open() bug when dealing with :memory: databases.</li>
<li>Fixed SQLiteCommand.ExecuteScalar() to return a properly-typed value.</li>
<li>Added support for SQLiteParameter.ResetDbType().</li>
<li>Added test cases for rigid and flexible type testing.</li>
</ul>
<p>
<b>1.0.45.0 - September 25, 2007</b></p>
<ul>
<li><strong>Breaking change in GetSchema("Indexes") </strong>-- MetaDataCollections
restrictions and identifier parts counts were wrong for this schema and I was using
the wrong final parameter as the final restriction.&nbsp; Meaning, if you use the
Indexes schema and are querying for a specific index the array should now be {catalog,
null, table, index } instead of {catalog, null, table, null, index}</li>
<li>Code merge with SQLite 3.4.2</li>
<li>Fixed some errors in the encryption module, most notably when a non-default
page size is specified in the connection string. </li>
<li>Fixed SQLiteDataReader to better handle type-less usage scenarios, which also
fixes problems with null values and datetimes.</li>
<li>Fixed the leftover temp files problem on WinCE </li>
<li>Added connection pooling.&nbsp; The default is disabled for now, but may change
in the future.&nbsp; Set "Pooling=True" in the connection string to enable it. </li>
<li>Sped up SQLiteConnection.Open() considerably.</li>
<li>Added some more robust cleanup code regarding SQLiteFunctions.</li>
<li>Minor additions to the code to allow for future LINQ integration into the main
codebase.</li>
<li>Fixed a long-standing bug in the Open() command of SQLiteConnection which failed
to honor the documented default behavior of the SQLite.NET provider to open the
database in "Synchronous=Normal" mode.&nbsp; The default was "Full". </li>
<li>If Open() fails, it no longer sets the connection state to Broken.&nbsp; It
instead reverts back to Closed, and cleans up after itself.</li>
<li>Added several new parameters to the ConnectionString for setting max page count,
legacy file format, and another called FailIfMissing to raise an error rather than
create the database file automatically if it does not already exist.</li>
<li>Fixed some designer toolbox references to the wrong version of the SQLite.Designer</li>
<li>Fixed a bug in the mergebin utility with regards to COR20 metadata rowsize computations.&nbsp;
</li>
<li>Minor documentation corrections &nbsp;&nbsp;</li>
</ul>
<p>
<b>1.0.44.0 - July 21, 2007</b></p>
<ul>
<li>Code merge with SQLite 3.4.1</li>
<li>Fixed a bug in SQLiteConnection.Open() which threw the wrong kind of error in
the wrong kind of way when a database file could not be opened or created.&nbsp;</li>
<li>Small enhancements to the TYPES keyword, and added documentation for it in the

help file.</li>
<li>Hopefully fixed the occasional SQLITE_BUSY errors that cropped up when starting
a transaction.&nbsp; Usually occurred in high-contention scenarios, and the underlying
SQLite engine bypasses the busy handler in this scenario to return immediately.</li>
</ul>
<p>
<b>1.0.43.0 - June 21, 2007</b></p>
<ul>
<li>Code merge with SQLite 3.4.0</li>
<li>Fixed a reuse bug in the SQLiteDataAdapter in conjunction with the SQLiteCommandBuilder.&nbsp;
It's been there unnoticed for more than a year, so it looks like most folks never
encountered it. </li>
<li>Fixed an event handler bug in SQLiteCommandBuilder in which it could fail to
unlatch from the DataAdapter when reused.&nbsp; Relates to the previous bugfix.</li>
<li>Fixed a double-dispose bug in SQLiteStatement that triggered a SQLiteException.&nbsp;</li>
</ul>
<p>
<b>1.0.42.0 - June 1, 2007</b></p>
<ul>
<li>Code merge with SQLite 3.3.17</li>
<li>Changed the SQLiteFunction static constructor so it only enumerates loaded modules
that have referenced the SQLite assembly, which hopefully should cut down dramatically
the time it takes for that function to execute.&nbsp;</li>
<li>Added the FTS2 full-text search extension to the project.&nbsp; Look for FTS1
to disappear within the next couple of revisions.&nbsp;</li>
<li>Fixed a bug introduced with the finalizers that triggered an error when statements
ended with a semi-colon or had other non-parsable comments at the end of a statement&nbsp;</li>
<li>Fixed an intermittent multi-threaded race condition between the garbage collector
thread and the main application thread which lead to an occasional SQLITE_MISUSE
error.</li>
<li>Fixed another issue relating to SQLite's inherent typelessness when dealing
with aggregate functions which could return Int64 or Double or even String for a
given row depending on what was aggregated.</li>
<li>Remembered to recompile the DDEX portion of the engine this time, so Compact
Framework users can once again use the design-time functionality</li>

<li>Code merge with SQLite 3.3.16</li>




<li>Second go at implementing proper finalizers to cleanup after folks who've forgotten
to Dispose() of the SQLite objects</li>
<li>Enhanced GetSchema(IndexColumns) to provide numeric scale and precision values</li>
<li>Fixed the column ordinals in GetSchema(IndexColumns) to report the ordinal of
the column in the index, not the table</li>
<li>Fixed a bug whereby parameters named with an empty string (such as String.Empty)
were treated like a named parameter instead of an unnamed parameter</li>
</ul>
<p>
<b>1.0.40.0 - January 31, 2007</b></p>
<ul>
<li>Code merge with SQLite 3.3.12</li>
<li>Lots of new code to handle misuse of the library.&nbsp; Implemented finalizers
where it made sense, fixed numerous garbage collector issues when objects are not
disposed properly, &nbsp;fixed some object lifetime issues, etc.</li>
<li>A failed Commit() on a transaction no longer leaves the transaction in an unusable
state.</li>
</ul>
<p>
<b>1.0.39.1 - January 11, 2007</b></p>
<ul>
<li>Fixed a really dumb mistake that for some reason didn't trigger any errors in
the testcases, whereby commands when associated with a connection were not adding
or removing themselves from an internal list of commands for that connection --
causing a "database is locked" error when trying to close the connection.</li>
</ul>
<p>
<b>1.0.39.0 - January 10, 2007</b></p>
<ul>
<li>Code merge with SQLite 3.3.10</li>
<li>Fixed a multi-threaded race condition bug in the garbage collector when commands
and/or connections are not properly disposed by the user. </li>
<li>Switched the encryption's internal deallocation code to use sqlite's built-in
aux functions instead of modifying the pager.c source to free the crypt block.&nbsp;
This eliminates the last of the code changes the provider makes to the original
SQLite engine sources.&nbsp; Props to Ralf Junker for pointing that out.</li>
</ul>
<p>
<b>1.0.38.0 - November 22, 2006</b></p>
<ul>
<li>Fixed a bug when using CommandBehavior.KeyInfo whereby integer primary key columns
may be duplicated in the results. </li>
<li>Enhanced the CommandBuilder so that update/delete statements are optimized when
the affected table contains unique constraints and a primary key is present.</li>
<li>Fixed a bug in the DataReader when used in conjunction with CommandBehavior.CloseConnection.</li></ul>
<p>
<b>1.0.37.0 - November 19, 2006</b></p>
<ul>
<li>Added support for CommandBehavior.KeyInfo.&nbsp; When specified in a query,
additional column(s) will be returned describing the key(s) defined for the table(s)
selected in the query.&nbsp; This is optimized when INTEGER PRIMARY KEY is set for
the given tables, but does additional work for other kinds of primary keys.</li>
<li>Removed the default values from SQLiteDataReader.GetTableSchema(), to better
follow Sql Server's pattern and suppress schema errors when loading the records
into a dataset/datatable.</li>
<li>Allow integers to implicitly convert to double/decimal/single.</li></ul>
<p>
<b>1.0.36.1 - October 25, 2006</b></p>
<ul>
<li>Added support for LONGVARCHAR, SMALLDATE and SMALLDATETIME. These were actually
added in 1.0.36.0 but were undocumented.</li>
<li>Fixed the embedded helpfile which was accidentally built from old sources. </li>
<li>Fixed an unfortunate re-entry of a bug in the .36 codebase that caused the provider
to "forget" about commands on a connection under certain circumstances.</li>
</ul>
<p>
<b>1.0.36.0 - October 23, 2006</b></p>
<ul>
<li>Code merge with SQLite 3.3.8, including support for full-text search via the
FTS1 extension.&nbsp;</li><li>Fixed a bug retrieving data types when UseUtf16Encoding
is true. Side-effect of further merging the common code between the two base classes.</li>
<li>Fixed a bug with System.Transactions whereby a connection closed/disposed within
a transaction scope is rolled back and cannot be committed.</li>
<li>Added more error checking and reporting to transactions to help user's isolate
the source of transaction failures.</li>
<li>Implemented a workaround for a Compact Framework issue regarding strong-named
assemblies containing a PE section with a raw size less than the virtual size.&nbsp;</li>
</ul>
<p>
<b>1.0.35.1 - September 12, 2006</b></p>
<ul>
<li>Fixed the TYPES keyword to work when UseUTF16Encoding is true.</li>
<li>Fix another bug revealed in 1.0.35.0 regarding infinite loops when the 2nd or
subsequent statements of a semi-colon separated command cannot be parsed.</li>
<li>Updated the help documentation.&nbsp;</li>
</ul>
<p>
<b>1.0.35.0 - September 10, 2006</b></p>
<ul>
<li>Fixed an infinite loop bug in SQLiteCommand caused when multiple semi-colon
separated statements in a single command are executed via datareader and one of
the statements contains a syntax error preventing it from being prepared.&nbsp;</li><li>
Added the TYPES preparser keyword to be placed before a SELECT statement to aid
the wrapper in converting expressions in a subsequent select clause into more robust
types.&nbsp; Documentation yet to be integrated, but available on the forums.</li>
<li>Added a new connectionstring parameter "BinaryGUID=true/false" (default is "true").&nbsp;
When true, guid types are stored in the database as binary blobs to save space.&nbsp;
Binary has been the default format since 1.0.32.0 but this parameter eases backward
compatibility.</li>
</ul>
<p>
<b>1.0.34.0 - September 4, 2006</b></p>
<ul>
<li>Fixed a bug in SQLiteParameterCollection.RemoveAt(namedparam)</li>
<li>Fixed a bug in SQLiteDataReader introduced in 1.0.30 that broke DateTimes using
the Ticks option in the connection string.</li>
<li>Fixed a bug in the recent changes to guid behavior wherein using a datareader's
indexer to fetch a guid from a column containing both binary and text guids would
sometimes return a byte array instead of a guid.</li>
<li>Enacted a workaround involving typed datasets in Compact Framework projects
in which it took an excessive amount of time to open a form and generated a lot
of temporary files in the user's Local Settings\Application Data\Microsoft\VisualStudio\8.0\Assembly
References folder.</li>
</ul>
<p>
<b>1.0.33.0 - August 21, 2006</b></p>
<ul>
<li>Code merge with SQLite 3.3.7</li>
<li>Fixed a bug in SQLiteConnection that caused it to "forget" about commands bound
to it and occasionally throw an error when a database is closed and opened repeatedly.&nbsp;
</li>
</ul>
<p>
<b>1.0.32.0 - August 6, 2006</b></p>
<ul>
<li>Added AllowPartiallyTrustedCallers attribute to the assembly</li><li>Added the
missing "nchar" type</li>
<li>Added support for binary Guid's.&nbsp; Guids are now stored as binary by default
when using parameterized queries.&nbsp; Text guids are still fully supported.</li>
<li>Fixed a TransactionScope() error that caused the transaction not to be completed.</li>
<li>Enhanced parameter names so that if they are added to the Parameters collection
without their prefix character (@ : or $) they are still properly mapped.&nbsp;</li>
</ul>
<p>
<b>1.0.31.0 - July 16, 2006</b></p>
<ul>
<li>Re-applied the view parsing bugfix in 1.0.29.0 that was accidentally reverted
out of the 30 build.</li><li>Fixed SQLiteCommand.ExecuteScalar() to return null
instead of DbNull.Value when no rows were returned.</li>
<li>Design-time installer now installs the package-based designer on full Visual
Studio versions.&nbsp; Express editions continue to use the packageless designer.</li>
<li>In Visual Studio (not Express), you can now right-click a SQLite connection
in the Server Explorer and vacuum the database and change the encryption password.</li>
</ul>
<p>
<b>1.0.30.1 - July 2, 2006</b></p>
<ul>
<li>Code merge with SQLite 3.3.6</li>
<li>Added support for the |DataDirectory| keyword in the Data Source filename string.&nbsp;
</li>
<li>Added hook notification support to SQLiteConnection.&nbsp; Specifically, there
are three new events on the SQLiteConnection object which are raised when an update/insert/delete
occurs and when transactions are committed and rolled back.</li><li>Changed SQLiteTransaction
to default to BEGIN IMMEDIATE instead of just BEGIN, which solves a multithreaded
race condition.&nbsp;</li>
<li>Changed SQLiteDataReader to better support SQLite's typelessness.&nbsp; The
data reader no longer caches column affinity, but re-evaluates it for each column/row.</li>
<li>Fixed a bug in Prepare() which caused an intermittant fault due to the code
accessing the memory of an unpinned variable.&nbsp;</li>
<li>Fixed a multithreaded lock-retry bug in in SQLiteConnection.Open() and in SQLiteTransaction,
which failed to use a command timeout before giving up.</li>
</ul>
<p>
<b>1.0.29.0 - May 16, 2006</b></p>
<ul>
<li>Fixed a bug in the Views schema information which caused multi-line view definition
statements not to be parsed</li>
<li>Fixed a parsing bug in SQLiteDataReader.GetSchemaTable() to account for numeric(x,y)
datatypes with specified precision and scale</li>
<li>Fixed a bug in SQLiteConnection.Open() which tried to automatically enlist in
an ambient transaction but had not yet set the state of the database to Opened,
thereby causing a transaction fault</li>
<li>Changed SQLiteException to inherit from DbException on the full framework</li>
</ul>
<p>
<b>1.0.28.0 - April 14, 2006</b></p>
<ul>
<li>Code merge with SQLite 3.3.5</li>
<li>You can now specify a relative path in the Compact Framework's "Data Source"
by prefixing the file with ".\".&nbsp; i.e. "Data Source=.\\mydb.db3"</li>
<li>Several more changes and enhancements to schemas for better compatibility.</li>
<li>Fixed several bugs with the 64-bit builds of the provider.&nbsp; The x64 binary
is now optimized.</li>
<li>Design-time installer now tries to install the 64-bit builds into the GAC along
with the 32-bit build.</li>
<li>Fixed a bug in the SQLiteDataReader.GetSchemaTable() function when used with
tables containing apostrophes.</li>
<li>Fixed an XSD-related bug whereby the XSD utility was unable to locate the provider
and could not generate typed datasets.</li>
<li>Added NTEXT and STRING datatypes to the list of recognized keywords (used for
schema retrieval).</li>
<li>Due to the XSD bug and other potential problems related to external build utilities,
changes to the installation of the designer have had to be made.&nbsp; The installer
used to write the DbProviderFactories XML into the devenv.exe.config file and its
express cousins, but now has to write instead to the machine.config.</li>
<li>Installer writes to both the 32-bit machine.config and the 64-bit machine.config
if it exists.&nbsp;</li>
</ul>
<p>
<b>1.0.27.1 - February 28, 2006</b></p>
<ul>
<li>Fixed a bug when doing data binding in Compact Framework projects that prevented
you from assigning a typed dataset to a bindingsource.&nbsp; It turns out, the CF
version of the SQLite provider needs to be flagged as retargetable so it'll work
in the design-time desktop environment.&nbsp; No changes were made to the desktop
build, but the revision was bumped on all libraries anyway in order to keep them
sync'd.&nbsp;</li></ul>
<p>
<b>1.0.27.0 - February 27, 2006</b></p>
<ul>
<li>Many optimizations and a few more minor adjustments to schemas and schema retrieval
performance.</li>
<li>Lots of design-time attributes added to the code.&nbsp; The DbDataAdapter, DbCommand,
and DbConnection objects now have greatly enhanced design-time capabilities when
added to the toolbox and dropped on a form.</li>
<li>Lots of Server Explorer enhancements.</li>
<li>Binaries are now distributed in a setup program for easier administration and
configuration of the provider.</li>
</ul>
<p>
<b>1.0.26.2 - February 15, 2006</b></p>
<ul>
<li>Yet another bugfix to index schemas, which was incorrectly marking most indexes
as primary key indexes.</li><li>Fixed GetSchema() to accept a null string array.</li><li>
Fixed a misspelled export in the core C library that prevented databases opened
with UTF16Encoding from getting schema information and would likely cause an error
if attempted.</li></ul>
<p>
<b>1.0.26.1 - February 14, 2006</b></p>
<ul>
<li>Fixed even more minor schema bugs having to do with indexes.</li><li>Added two
missing pieces in the SQLite designer which were preventing it from being used from
within VS Express editions.&nbsp;</li><li>Several bugfixes to the design-time installer
program, including supporting 64-bit environments.</li></ul>
<p>
<b>1.0.26.0 - February 11, 2006</b></p>
<ul>
<li>Code merge with SQLite 3.3.4</li><li>Fixed an encryption bug when changing the
password of databases over 1gb in size.&nbsp;</li><li>Fixed various designer issues
related to construction of named parameters.</li>
<li>Retooled the GetSchema() method of SQLiteDataReader to use the new 3.3.4 API
functions, and made several enhancements and fixes to schemas.&nbsp;</li>
<li>Implemented the SourceColumnNullMapping property of SQLiteParameter to fix a
DbCommandBuilder code generation bug.&nbsp;</li><li>Removed the runtime dependency
on MSVCR80.DLL.&nbsp; File size is somewhat larger for the varying desktop versions.</li><li>
Created an install program to manage installation and uninstallation of the SQLite
design-time support.</li>
<li>Designer support now works for all Visual Studio editions, including all Express
Editions.</li>
<li>Design-time installer will now remove (if present) the machine.config SQLite

entries in favor of installing the xml code into the devenv.exe.config file (or
any of the variations for express editions).&nbsp; The officially-accepted behavior
of using DbProviderFactories is to add the code to your app.config file, and the
machine.config file should not be touched.</li>
</ul>
<p>
<b>1.0.25.0 - January 31, 2006</b></p>
<ul>
<li>Code merge with SQLite 3.3.3</li><li>Added automatic distributed transaction
enlistment and implemented the DbConnection.EnlistTransaction method for manual
enlistment.</li>
<li>Nested transactions are now supported.</li>
<li>Rearranged the timing of SetPassword(), which now must be called before the
database is opened instead of afterwards.&nbsp; Optionally, the password can be
supplied in the ConnectionString.</li>
<li>Fixed a bug in SQLiteFunction that caused a failure when an empty resultset
was returned and a custom user aggregate function was used in the query.</li>
<li>The designer has had another round of cleanup applied, in preparation for moving
to a VS package.</li>
<li>Added SQLiteMetaDataCollectionNames class.</li>
</ul>
<p>
<b>1.0.24.6 beta - January 23, 2006</b></p>
<ul>
<li>This beta is built from sqlite.org's 3.3.2 beta.</li><li>Eliminated the static
linking of mscoree from all binaries.&nbsp; Native projects can now use the library
without any dependencies on the .NET framework, while managed projects continue
to be able to use the library normally.</li></ul>
<p>
<b>1.0.24.5 beta - January 20, 2006</b></p>
<ul>
<li>This beta is built from sqlite.org's 3.3.1 alpha and contains development-in-progress
code.&nbsp; Therefore no guarantees can be made regarding its suitability for production
use.</li>
<li><strong>You no longer need to distribute 2 files on the CompactFramework.&nbsp;
You can delete SQLite.Interop.DLL entirely.&nbsp; </strong>I wrote a custom tool
called "mergebin" (available in the source zip file) which combines the two libraries
and gets around a glaring defect in the VS2005 linker for ARM processors which doesn't
allow you to link netmodules.</li>
<li><strong>x64 and ia64 builds now use the same strong name as the x86 build.</strong>&nbsp;
This means breaking backward compatibility, but it was necessary in order to allow
you to drop any of those 3 builds onto a PC and have your .NET program run properly.&nbsp;
Prior to this, you'd get an error if you built your program using the x86 build,
and then installed the x64 version on a target machine and tried to run your program
against it.</li>
<li>The entire source project has been gone over top to bottom.&nbsp; A debug build
no longer combines the binaries into a single module, which was preventing proper
debugging.</li></ul>
<p>
<b>1.0.24.4 beta - January 16, 2006</b></p>
<ul>
<li>This beta is built from sqlite.org's 3.3.1 alpha and contains development-in-progress
code.&nbsp; Therefore no guarantees can be made regarding its suitability for production
use.</li>
<li>Fixed a bug in the UTF-16 handling code for preparing statements due to a behavioral
change in SQLite 3.3.0.</li>
<li>Added pager.c code necessary to cleanup after an encrypted file is closed.</li>
<li>Fixed an encryption bug that caused a fault when an encrypted file was rolled
back.</li>
<li>Modified the testcase code to take advantage of optimizations regarding the
use of a DbCommandBuilder.&nbsp; DataAdapter insert speed increased dramatically
as a result.</li>
</ul>
<p>
<b>1.0.24.3 beta - January 10, 2006</b></p>
<ul>
<li>This beta is built from sqlite.org's 3.3.0 alpha and contains development-in-progress
code.&nbsp; Therefore no guarantees can be made regarding its suitability for production
use.</li><li>Added support for database encryption at the pager level.&nbsp; Databases
are encrypted using a 128-bit RC4 stream algorithm.&nbsp; To open an existing encrypted
database, you may now specify a "Password={password}" text in the ConnectionString,
or you may call the SQLiteConnection.SetPassword() function to set the password
on an open connection. &nbsp;To encrypt existing non-encrypted databases or to change
the password on an encrypted database, you must use the SQLiteConnection.ChangePassword()
function.&nbsp; If you use SetPassword() instead of specifying a password in the
connection string, or call ChangePassword() you may use a binary byte array or a
text string as the password.</li>
<li>Rewrote the locking implementation for the Compact Framework.&nbsp; It is now
more robust and incorporates into the SQLite codebase more efficiently than the
previous CE adaptation.</li>
<li>Moved some of the embedded schema XML data into a resource file to ease code
readability.</li>
<li>Automated the fixup of the original SQLite codebase's source prior to compiling,
to ease merging with sqlite.org's source.</li>
<li>Fixed a memory leak in SQLiteCommand due to it not removing an internal reference
to itself in SQLiteConnection.&nbsp; </li>
</ul>
<p>
<b>1.0.24.2 - December 30, 2005</b></p>
<ul>
<li>Fixed the SQLiteDataReader.HasRows property to return the proper value.</li>
<li>Implemented the inadvertently neglected RecordsAffected property on SQLiteDataReader.
</li>
<li>SQLiteFunction static constructor was changed to pre-filter classes with only
the SQLiteFunctionAttribute.&nbsp; The code was throwing an exception when certain
assemblies were referenced in a project. </li>
<li>Fixed the SQLiteDataAdapter OnRowUpdated event, which was using the wrong variable
to find the attached event handler and subsequently not raising the event.</li>
<li>Small optimizations and fixes to SQLiteDataReader.NextResult().&nbsp;</li>
</ul>
<p>
<b>1.0.24.1 - December 19, 2005</b></p>
<ul>
<li>Update core SQLite engine to 3.2.8&nbsp;</li></ul>
<p>
<b>1.0.24 - December 9, 2005</b></p>
<ul>
<li>Fixed the<em> Catalogs</em> schema bug that caused attached databases not to
be re-attached to a cloned connection </li>
<li>Enhanced transactions to allow for a deferred or immediate writelock. &nbsp;SQLiteConnection.BeginTransaction()
now has an additional overload to support it&nbsp;</li><li>Commands are now prepared
as they are executed instead of beforehand.&nbsp; This fixes a bug whereby a multi-statement
command that alters the database and subsequently references the altered data would
fail during Prepare().</li><li>Tightened up the SQLiteDataReader to prevent reading
columns before calling the first Read() and to prevent reading columns after the
last Read().</li>
<li>A more descriptive error is thrown if there aren't enough parameters in the
command to satisfy the parameters required by the statement(s).&nbsp;</li>
</ul>
<p>
<b>1.0.23 - November 21, 2005</b></p>
<ul>
<li>Named parameters may now begin with <strong>@</strong> to ease portability of
the provider. SQLite's named parameters are ordinarily prefixed with a <strong>:
</strong>or<strong> $</strong>.&nbsp; The designer will still use the <strong>$</strong>
prefix however, since its more compatible with the default SQLite engine.</li><li>
Added several alternate ISO8601 date/time formats to SQLiteConvert.cs to increase
compatibility.</li>
<li>Relaxed coersion restrictions to work better with SQLite's inherent typelessness.&nbsp;</li>
</ul>
<p>
<b>1.0.22 - November 11, 2005</b></p>
<ul>
<li>Fixed some globalization issues which resulted in incorrect case-insensitive
comparisons</li>
<li>Fixed a bug in the routine that finds all user-defined functions in a loaded
assembly.&nbsp; It would throw an exception if any of the types in the assembly
could not be loaded.&nbsp; The exception is now caught and handled appropriately.</li>
</ul>
<p>
<b>1.0.21 - November 4, 2005</b></p>
<ul>
<li>Fixed a designer bug when creating typed datasets with parameterized queries.</li>
<li>The above fix then exposed another bug in the datareader's ability to query
schema information on parameterized commands, which was also fixed.</li>
<li>Compiled against the RTM version of VS2005.</li>
<li>Rewrote the design-time install script to use the XML DOM objects when writing
to the machine.config and to automatically register the DLL in the GAC.</li><li>
Made changes to the app.config descriptions and help file to improve version-independent

factory support.</li></ul>
<p>
<b>1.0.20 - October 19, 2005</b></p>
<ul>
<li>Fixed a shortcut in SQLiteBase.GetValue which was insufficient for international
environments.&nbsp; The shortcut was removed and the "proper" procedure put in.</li></ul>
<p>
<b>1.0.19 - October 5, 2005</b></p>
<ul>
<li>Code merge with SQLite 3.2.7
<li>Fixed bugs in the CE port code (os_wince.c)&nbsp;which were brought to light&nbsp;by&nbsp;recent
changes in the SQLite engine.
<li>Recompiled and modified to be compatible with the September VS2005 Release Candidate.<br />
Beta 2 users should continue to use 1.0.18.1</li></ul>
<p>
<b>1.0.18.1 - September 19, 2005</b></p>
<ul>
<li>Code merge with SQLite 3.2.6</li></ul>
<p>
<b>1.0.18 - September 1, 2005</b></p>
<ul>
<li>Added type-specific method calls when using the various SQLite classes that
would've normally returned a a generic Db base class, which aligns the code better
with the Microsoft-supplied data providers.</li></ul>
<p>
<b>1.0.17 - August 26, 2005</b></p>
<ul>
<li>Code merge with SQLite 3.2.5
<li>Added Itanium and x64 build settings to the project (needs testing)
<li>Bugfixes and enhancements to several schema types
<li>Additional design-time support to include index and foreign key enumerations.&nbsp;
Requires re-registering the designer using INSTALL.CMD.&nbsp; The new designer code
now allows the VS query designer and typed datasets to automatically link up foreign
keys, use indexes, and automatically generate relationships from the schema.<li>
Additional static methods on SQLiteConnection to create a database file, encrypt
a file using the Encrypted File System (EFS) on NTFS (requires NT 2K or above) and

NTFS file compression</li>
</ul>
<p>
<b>1.0.16 - August 24, 2005</b></p>
<ul>
<li>Code merge with SQLite 3.2.4 with the large delete bugfix in CVS (which will
become 3.2.5 soon)
<li>Added new GetSchema() types: IndexColumns, ViewColumns, ForeignKeys</li>
</ul>
<p>
<b>1.0.15 - August 22, 2005</b><br />
</p>
<ul>
<li>Code merge with SQLite 3.2.3
<li>Minor updates for better design-time experience. More design-time code to follow
in subsequent releases.</li>
</ul>
<p>
<b>1.0.14 - August 16, 2005</b><br />
</p>
<ul>
<li>Fixed a bug in the SQLiteDataAdapter due to insufficient implementation of the
class.&nbsp; The RowUpdating and RowUpdated events are now properly implemented,
but unfortunately inserting and updating data in a DataTable or DataSet is now much
slower.&nbsp; This is the proper design however, so the changes are here to stay.
<li>Lots of schema changes to support Visual Studio's Data Designer architecture.<li>
Added Designer support for the provider.&nbsp; It's not 100%, but you can design
queries, add typed datasets and perform quite a number of tasks all within Visual
Studio now.</li></ul>
<p>
<b>1.0.13 - August 8, 2005</b><br />
</p>
<div>
<ul>
<li>Fixed a named parameter bug in the base SQLite_UTF16 class, which of course
only showed up when a database connection was opened using the UseUTF16Encoding=True
parameter.
<li>Fixed a performance issue in SQLite_UTF16 involving string marshaling.</li></ul>
</div>
<p>
<b>1.0.12 - August 5, 2005</b><br />
</p>
<div>
<ul>
<li>Full support for the Compact Framework.&nbsp; Each build (Debug/Release) now
has a&nbsp;platform, either Win32 or Compact Framework.&nbsp; The correct projects
are built accordingly.&nbsp; See the&nbsp;<a href="#redist">Distributing SQLite</a>
section for information on what files need to be distributed for each platform.&nbsp;
<li>Modified SQLite3.Reset() and Step() functions to transparently handle timeouts
while waiting on the database to become available (typically when a writer is waiting
on a reader to finish, or a reader is waiting on a writer to finish).
<li>Lots of code cleanup&nbsp;as suggested&nbsp;by the Code Analyzer (FxCop).
<li>Lots of updates to the helpfile (as you can see).
<li>Statements&nbsp;were already prepared lazily&nbsp;in a SQLiteCommand, but now
its even more lazy.&nbsp; Statements are now only prepared if the statements haven't
been previously prepared and a Prepare() function is called (and the command is
associated with a connection) or just prior to the command being executed.&nbsp;</li></ul>
</div>
<p>
<b>1.0.11 - August 1, 2005</b><br />
</p>
<ul>
<li><strong>For everything except the Compact Framework, System.Data.SQLite.DLL
is now the <em>only</em> DLL required to use this provider!</strong>&nbsp; The assembly
is now a multi-module assembly, containing both the native SQLite3 codebase and
the C# classes built on top of it.&nbsp; The Compact Framework version (when completed)
will not be able to support this feature, so backwards compatibility with the Compact
Framework has been preserved for the future.
<li>Fixed a bug in SQLiteCommand.ExecuteScalar() that caused it to stop executing
commands once it obtained the first column of the first row-returning resultset.&nbsp;
Any remaining statements after the row-returning statement was ignored. </li>
</ul>
<p>
<b>1.0.10 - June 10, 2005</b><br />
</p>
<ul>
<li>Fixed a bug in the SQLite3.cs Prepare() function that created a statement even
when the SQLite engine returned a NULL pointer. Typically this occurs when multiple
statements are processed and there are trailing comments at the end of the statement.
<li>Fixed a bug in SQLiteStatement.cs that retrieved parameter names for a parameterized
query.&nbsp; SQLite's parameters are 1-based, and the function was starting at 0.&nbsp;
This was fine when all parameters were unnamed, but for named parameters it caused
the parameters to be out of whack. </li>
</ul>
<p>
<b>1.0.09a - May 25, 2005</b><br />
</p>
<ul>
<li>Fixed a broken helpfile and corrected some obsolete help remarks in SQLiteFunction.cs
<li>Added a version resource to the SQLite.Interop.DLL.&nbsp;</li></ul>
<p>
<b>1.0.09 - May 24, 2005</b><br />
</p>
<ul>
<li>Code merge with the latest 3.21 version of SQLite.
<li>Removed obsolete methods and properties for Whidbey Beta 2</li></ul>
<p>
<b>1.0.08 Refresh - Mar 24, 2005<br />
</b>
</p>
<ul>
<li>Code merge with the latest 3.20 version of SQLite.
<li>Recompiled the help file to fix a build error in it. </li>
</ul>
<p>
<b>1.0.08 - Mar 11, 2005<br />
</b>
</p>
<ul>
<li>Added additional #if statements to support the old beta 1 edition of VS2005.
<li>Code merged the SQLite 3.14 source. </li>
</ul>
<p>
<b>1.0.07 - Mar 5, 2005</b><br />
</p>
<ul>
<li>Made more optimizations to frequently-called functions, resulting in significant
performance gains in all tests.
<li>Recompiled the binaries using the latest VS2005 February CTP, resulting in yet
more significant speed gains.&nbsp; The 100k insert test used to take 3.5 seconds
and the insertwithidentity took almost 8 seconds.&nbsp; With the above two changes,
those tests are now executing in 1.9 and 4.9 seconds respectively.</li></ul>
<p>
<b>1.0.06 - Mar 1, 2005<br />
</b>
</p>
<ul>
<li>Speed-ups to SQLiteDataReader.&nbsp; It was interop'ing unnecessarily every
time it tried to fetch a field due to a logic error.
<li>Changed/Added some code to SQLiteConvert's internal DbType, Type and TypeAffinity
functions.
<li>Fixed the SQLiteDataReader to obey the flags set in the optional CommandBehavior
flag from SQLiteCommand.ExecuteReader().
<li>Changed the default page size to 1024 to reflect the defaults of SQLite.&nbsp;
Ignores the "Page Size" connection string option for memory databases, as tests
revealed that changing it resulted in memory corruption errors.
<li>Performance enhancements to the SQLiteCommand and SQLiteStatement classes which
reduced the 100,000 row insert execution time as well as the various Function execution
times significantly. </li>
</ul>
<p>
<b>1.0.05 - Feb 25, 2005</b>
</p>
<ul>
<li>Fixed the SQLite3 C# class step/reset functions to accomodate schema changes
that invalidate a prepared statement.&nbsp; Statements are recompiled transparently.
<li>Moved all native DLL declarations to an UnsafeNativeMethods class.
<li>Split several classes into their own modules for readability.
<li>Renamed many internal variables, reviewed access to variables marked as internal
and altered their protection levels accordingly.
<li>Due to the presence of the altered sqlite3 codebase and so many added interop
functions, I decided to rename the sqlite3 C project and the DLL to SQLite.Interop.DLL.&nbsp;
This is the same core sqlite3 codebase but designed specifically for this ADO.NET
provider.&nbsp; This eliminates any possibility of someone dropping another build
of sqlite3.dll into the system and rendering the provider inoperable.&nbsp; In the
future if the folks at sqlite.org finally introduce a method of retrieving column
usage for an arbitrary prepared statement, I'll retool this library to be a lightweight
function call wrapper around the core binary distribution.
<li>Added [SuppressUnmanagedCodeSecurity] attribute to the UnsafeNativeMethods class
which brings VS2005 November CTP execution speeds inline with the December CTP.
<li>Added a <b>bin</b> directory to the project root where pre-compiled binaries
can be found.
<li>Added a <b>doc</b> directory where preliminary documentation on the class library
can be found.
<li>Documented a lot more of the classes internally. </li>
</ul>
<p>
<b>1.0.04 - Feb 24, 2005</b>
</p>
<ul>
<li>Removed the SQLiteContext class and revamped the way UserFunctions work to simplify
the imlementation.
<li>Fixed a counting bug in the TestCases class, specifically in the function tests
where I wasn't resetting the counter and it was consequently reporting intrinsic
and raw select calls as being much much faster than they actually were.&nbsp; The
numbers are now much closer to what I expected for performance, with .NET user-functions
still being the slowest, but only by a small margin.
<li>Small performance tweaks to SQLiteDataReader.
<li>Added PageSize to the SQLiteConnectionStringBuilder and subsequently to the
SQLiteConnection
<li>Added a PRAGMA encoding=XXX execution statement to the SQLiteConnection after
opening a connection. </li>
</ul>
<p>
<b>1.0.03 - Feb 23, 2005</b>
</p>
<ul>
<li>Fixed up SQLiteCommandBuilder to correct implementation errors, which resulted
in an enormous performance boost in the InsertMany test.&nbsp;&nbsp; 10,000 row
insert that executed in 1500ms now executes in 500ms.
<li>Fixed several errors in the SQLite3_UTF16 class.&nbsp; ToString() was working
incorrectly and the Open() method failed to register user defined functions and
collations.
<li>Fixed a bug in SQLiteCommand.ClearCommands() whereby only the first statement
was being properly cleaned up.
<li>Fixed a bug in SQLiteDataReader whereby calling NextResult() would not properly
reset the previously-executed command in the sequence.
<li>Added an InsertManyWithIdentityFetch test, which appends a select clause to
populate the ID of the last inserted row into the InsertCommand, demonstrating ADO.NET's
ability to auto-fetch identity columns on insert. </li>
</ul>
<p>
<b>1.0.02 - Feb 21, 2005</b></p>
<ul>
<li>Tweaks to the xxx_interop functions that return char *'s, so they also return
the length.&nbsp; Saves an interop call to get the UTF-8 string length during conversion
to a .NET string.
<li>Reworked the whole interop.c thing into interop.h and reduced the code required
to merge the main sqlite3 codebase.
<li>Added support for user-defined collations. </li>
</ul>

    ADO.NET 2.0 SQLite Data Provider<br />
    Version 1.0.6 - Feb 28, 2005<br />

    Written by Robert Simpson (<a href="mailto:robert@blackcastlesoft.com">robert@blackcastlesoft.com</a>)<br />
    Released to the public domain, use at your own risk!<br />


    <br />


    This provider was written and verified using the Visual Studio 2005 November and
    December CTP's.<br />
    <br />
    The latest version can be downloaded <a href="http://www.blackcastlesoft.com/files/system.data.sqlite.zip">here</a>





































    <br />




















    <br />





    <b>Features:</b><br />
    <ul>
      <li>DbProviderFactory support, just add the XML below at the machine.config and/or app.config level. </li>


      <li>Full support for ATTACH'ed databases.&nbsp; Exposed as <i>Catalogs</i> in the
        schema.&nbsp; When cloning a connection, all attached databases are automatically
        re-attached to the new connection.</li>



      <li>DbConnection.GetSchema(...) support includes the <i>MetaDataCollections</i>, <i>

        DataSourceInformation</i>, <i>Columns</i>, <i>Tables</i>, <i>Views</i>, <i>Catalogs</i>



        and <i>Indexes</i> keywords.</li>

      <li>Enhanced DbDataReader.GetSchemaTable() functionality returns catalog, namespace
        and detailed schema information even for complex queries.</li>


      <li>Named and unnamed parameters.</li>


      <li>Full UTF-8 and UTF-16 support.</li>




      <li>Multiple simultaneous DataReaders (one DataReader per Command however).</li>



      <li>Full support for user-defined scalar and aggregate functions, encapsulated into
        an
        easy-to-use base class in which only a couple of overrides are necessary to implement
        new SQL functions.</li>



      <li>Full support for user-defined collating sequences, every bit as simple to implement
        as user-defined functions and uses the same base class.</li></ul>


















    In order to use the SQLiteFactory and have the SQLite data provider enumerated in
    the DbProviderFactories methods, you must add the following segment into either
    your application's app.config or the system's machine.config located in the %SystemRoot%\Microsoft.Net\Framework\v2.xxxx\Config
    folder:<br />
    <br />
    <pre>
&lt;configuration&gt;
  &lt;system.data&gt;
    &lt;DbProviderFactories&gt;

      &lt;add name="SQLite Data Provider" invariant="System.Data.SQLite" support="3F" description=".Net Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" /&gt;

    &lt;/DbProviderFactories&gt;
  &lt;/system.data&gt;
&lt;/configuration&gt;
</pre>




    <br />



















    <b>Development Notes Regarding the SQLite 3 Source Code<br />
    </b>*** At this time, the necessary changes to the DLL to support Windows CE have






    not been completed.&nbsp; All function calls that return or pass a 64-bit value

    have been wrapped, but the necessary OS changes have not been finished.<br />
    <br />

      <p></p>




















    <p>





































      Steps for merging the sqlite3 core codebase:</p>
















    <ol>

        http://www.sqlite.org/download.html</a></li>
      <li>Extract the source code to the <b>SQLite.Interop\src</b> directory of this project</li>

      <li>Add <b>#include "../interop.h" </b>to the top of the file where the other include's

      <li>Scroll down the <b>select.c</b> file to around line <b>748</b>.&nbsp; Change the name of the function <b>static void generateColumnNames </b>to

      <b>Version History<br />


































        1.06 - Feb 28, 2005<br />









      </b>


    <ul>






























      <li>Speed-ups to SQLiteDataReader.&nbsp; It was interop'ing every time it tried to


















        fetch a field due to a logic error.</li>










      <li>Changed/Added some code to SQLiteConvert's internal DbType, Type and TypeAffinity










































        functions.</li>



      <li>Fixed the SQLiteDataReader to obey the flags set in the optional CommandBehavior
        flag from SQLiteCommand.ExecuteReader().</li>




		<li>Changed the default page size to 1024 to reflect the defaults of 



















		SQLite.&nbsp; Ignores the &quot;Page Size&quot; connection string option for 
		memory databases, as tests revealed that changing it resulted in memory 













































		corruption errors.</li>
      <li>Performance enhancements to the SQLiteCommand and SQLiteStatement classes which













        reduced the 100,000 row insert execution time as well as the various Function execution













        times significantly.</li>




    </ul>
    <b>











      <br />
        1.05 - Feb 25, 2005</b>



















































































    <ul>










      <li>Fixed the SQLite3 C# class step/reset functions to accomodate schema changes

        that invalidate a prepared statement.&nbsp; Statements are recompiled transparently.</li>



      <li>Moved all native DLL declarations to an UnsafeNativeMethods class.</li>










      <li>Split several classes into their own modules for readability.</li>









      <li>Renamed many internal variables, reviewed access to variables marked as internal
        and altered their protection levels accordingly.</li>












      <li>Due to the presence of the altered sqlite3 codebase and so many added interop








        functions, I decided to rename the sqlite3 C project and the DLL to SQLite.Interop.DLL.&nbsp;

















        This is the same core sqlite3 codebase but designed specifically for this
        ADO.NET provider.&nbsp; This eliminates any possibility of someone dropping another
        build of sqlite3.dll into the system and rendering the provider inoperable.&nbsp;
        In the future if the folks at sqlite.org finally introduce a method of retrieving




        column usage for an arbitrary prepared statement, I'll retool this library to be











        a lightweight function call wrapper around the core binary distribution.</li>































      <li>Added [SuppressUnmanagedCodeSecurity] attribute to the UnsafeNativeMethods class





        which brings VS2005 November CTP execution speeds inline with the December CTP.</li>




		<li>Added a <b>bin</b> directory to the project root where pre-compiled 




























































		binaries can be found.</li>




		<li>Added a <b>doc</b> directory where preliminary documentation on the 























		class library can be found.</li>










		<li>Documented a lot more of the classes internally.</li>
    </ul>
      <b>











        <br />
























        1.04 - Feb 24, 2005</b>
    <ul>


      <li>Removed the SQLiteContext class and revamped the way UserFunctions work to simplify












































        the imlementation.</li>

      <li>Fixed a counting bug in the TestCases class, specifically in the function tests
        where I wasn't resetting the counter and it was consequently reporting intrinsic
        and raw select calls as being much much faster than they actually were.&nbsp; The









        numbers are now much closer to what I expected for performance, with .NET user-functions





















        still being the slowest, but only by a small margin.</li>



















      <li>Small performance tweaks to SQLiteDataReader.</li>

















      <li>Added PageSize to the SQLiteConnectionStringBuilder and subsequently to the SQLiteConnection</li>

      <li>Added a PRAGMA encoding=XXX execution statement to the SQLiteConnection after





        opening a connection.</li>






    </ul>
      <b>

















        1.03 - Feb 23, 2005</b>
    <ul>


























      <li>Fixed up SQLiteCommandBuilder to correct implementation errors, which resulted















        in an enormous performance boost in the InsertMany test.&nbsp;&nbsp; 10,000 row
        insert that executed in 1500ms now executes in 500ms.</li>










      <li>Fixed several errors in the SQLite3_UTF16 class.&nbsp; ToString() was working
























        incorrectly and the Open() method failed to register user defined functions and
        collations.</li>












      <li>Fixed a bug in SQLiteCommand.ClearCommands() whereby only the first statement

        was being properly cleaned up.</li>





      <li>Fixed a bug in SQLiteDataReader whereby calling NextResult() would not properly






        reset the previously-executed command in the sequence.</li>





      <li>Added an InsertManyWithIdentityFetch test, which appends a select clause to populate


















        the ID of the last inserted row into the InsertCommand, demonstrating ADO.NET's












        ability to auto-fetch identity columns on insert.</li>




    </ul>
    <p>

      <b>
















        1.02 - Feb 21, 2005</b></p>

    <ul>














































































































      <li>Tweaks to the xxx_interop functions that return char *'s, so they also return
        the length.&nbsp; Saves an interop call to get the UTF-8 string length during conversion
        to a .NET string.</li>
      <li>Reworked the whole interop.c thing into interop.h and reduced the code required
        to merge the main sqlite3 codebase.</li>
      <li>Added support for user-defined collations.</li>
    </ul>

    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">

    There are any number of "resheader" rows that contain simple 
    name/value pairs.
    
    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.
    
    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:
    
    Note - application/x-microsoft.net.object.binary.base64 is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.
    
    mimetype: application/x-microsoft.net.object.binary.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.
    
    mimetype: application/x-microsoft.net.object.soap.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.bytearray.base64
    value   : The object must be serialized into a byte array 
            : using a System.ComponentModel.TypeConverter
            : and then encoded with base64 encoding.

  <!-- 
    Microsoft ResX Schema 
    
    Version 2.0
    
    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.
    
    Example:
    
    ... ado.net/XML headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">2.0</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
        <value>[base64 mime encoded serialized .NET Framework object]</value>
    </data>
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
        <comment>This is a comment</comment>
    </data>
                
    There are any number of "resheader" rows that contain simple 
    name/value pairs.
    
    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.
    
    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:
    
    Note - application/x-microsoft.net.object.binary.base64 is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.
    
    mimetype: application/x-microsoft.net.object.binary.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.
    
    mimetype: application/x-microsoft.net.object.soap.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.bytearray.base64
    value   : The object must be serialized into a byte array 
            : using a System.ComponentModel.TypeConverter
            : and then encoded with base64 encoding.

  <!-- 
    Microsoft ResX Schema 
    
    Version 2.0
    
    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.
    
    Example:
    
    ... ado.net/XML headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">2.0</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
        <value>[base64 mime encoded serialized .NET Framework object]</value>
    </data>
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
        <comment>This is a comment</comment>
    </data>
                
    There are any number of "resheader" rows that contain simple 
    name/value pairs.
    
    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.
    
    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:
    
    Note - application/x-microsoft.net.object.binary.base64 is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.
    
    mimetype: application/x-microsoft.net.object.binary.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.
    
    mimetype: application/x-microsoft.net.object.soap.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.bytearray.base64
    value   : The object must be serialized into a byte array 
            : using a System.ComponentModel.TypeConverter
            : and then encoded with base64 encoding.

<title>Build Procedures</title>

<a name="procedures"></a>
<h2>Build Procedures</h2>

<p>
  Follow these steps to build the System.Data.SQLite (SDS) binaries.
  Unless otherwise noted, all steps need to be done in the order specified.
</p>

<p>
  You will need a Visual Studio 2008, 2008 SP1, 2010, or 2010 SP1 development
  environment for this build.
</p>

<p>
  The new build system has been setup using modular solution, project, and
  property files.
</p>

<p>
  In general, files with 2008 in the name (e.g.
  &quot;SQLite.Interop.2008.vcproj&quot;) or files ending in
  &quot;.vsprops&quot; are project and property files for the Visual Studio 2008
  solution.  Files with 2010 in the name (e.g.
  &quot;SQLite.Interop.2010.vcxproj&quot;) or files ending in &quot;.props&quot;
  are project and property files for the Visual Studio 2010 solution.  When
  making changes, you should make changes to both to keep them in sync.
</p>

<p>
  You can either [./build.wiki#manual | manually build] the System.Data.SQLite
  binaries using one of the supplied Visual Studio solutions or follow the steps
  outlined in the [./build.wiki#automated | Automated Build] section below.
</p>

<a name="assumptions"></a>
<h2>Build Assumptions &amp; Prerequisites</h2>

<ol>
  <li>
    We want to ship managed binaries that rely on the .NET Framework 2.0 SP2 (or
    for the LINQ assembly, the .NET Framework 3.5 SP1).  The .NET Framework 2.0
    is very widely deployed and binaries produced for it can also be referenced
    and used successfully from projects using the .NET Framework 4.0.
  </li>

  <li>
    We want to ship native binaries that rely on the Visual C++ 2008 Runtime.
  </li>

  <li>
    We want to ship the separate managed-only &quot;System.Data.SQLite.dll&quot;
    assembly and the &quot;SQLite.Interop.dll&quot; native library.  This will
    make it easier to maintain and deploy the included core SQLite code (in the
    &quot;SQLite.Interop.dll&quot; native library).  We also want to ship the
    &quot;monster DLL&quot; (i.e. the mixed-mode
    &quot;System.Data.SQLite.dll&quot; assembly that includes all the necessary
    native and managed code).  This will make it easier for developers that wish
    to register the assembly in the Global Assembly Cache (GAC).
  </li>

  <li>
    The machine used to prepare the official releases will have the
    [http://www.microsoft.com/downloads/en/details.aspx?FamilyID=ab99342f-5d1a-413d-8319-81da479ab0d7 | .NET Framework 3.5 SP1]
    and the corresponding
    [http://www.microsoft.com/downloads/details.aspx?FamilyId=E6E1C3DF-A74F-4207-8586-711EBE331CDC | SDK]
    installed.
  </li>

  <li>
    The machine used to prepare the official releases will have
    [http://www.jrsoftware.org/isdl.php | Inno Setup 5.4.2] or higher installed
    in &quot;%ProgramFiles%\Inno Setup 5&quot; or &quot;%ProgramFiles(x86)%\Inno
    Setup 5&quot; for an 64-bit machines.  Alternatively, the Inno Setup
    directory may be included in the PATH environment variable.
  </li>

  <li>
    The string &quot;&lt;root&gt;&quot; represents the root of your source tree
    for the System.Data.SQLite project.
  </li>

  <li>
    The string &quot;&lt;year&gt;&quot; represents the version of Visual Studio
    being used (e.g. 2008).
  </li>
</ol>

<a name="all"></a>
<h2>All Builds</h2>

<ol>
  <li>
    Make sure the version information is correct for SQLite in all of the
    following files:

    <ul>
      <li>&lt;root&gt;\SQLite.Interop\props\sqlite3.vsprops</li>
      <li>&lt;root&gt;\SQLite.Interop\props\sqlite3.props</li>
    </ul>

    You'll need to update the SQLITE_MANIFEST_VERSION and SQLITE_RC_VERSION
    properties.  This version number should track the release versions of SQLite
    (i.e. [http://www.sqlite.org/changes.html | 3.7.x]).
  </li>

  <li>
    Make sure the version information is correct for System.Data.SQLite in the
    following files:

    <ul>
      <li>&lt;root&gt;\SQLite.nuspec</li>
      <li>&lt;root&gt;\SQLite.MSIL.nuspec</li>
      <li>&lt;root&gt;\SQLite.x86.nuspec</li>
      <li>&lt;root&gt;\SQLite.x64.nuspec</li>
      <li>&lt;root&gt;\Doc\Extra\dbfactorysupport.html</li>
      <li>&lt;root&gt;\Doc\Extra\welcome.html</li>
      <li>&lt;root&gt;\Membership\Properties\AssemblyInfo.cs</li>
      <li>&lt;root&gt;\SQLite.Designer\AssemblyInfo.cs</li>
      <li>&lt;root&gt;\SQLite.Interop\props\SQLite.Interop.vsprops</li>
      <li>&lt;root&gt;\SQLite.Interop\props\SQLite.Interop.props</li>
      <li>&lt;root&gt;\SQLite.Interop\src\win\interop.h</li>
      <li>&lt;root&gt;\System.Data.SQLite\AssemblyInfo.cs</li>
      <li>&lt;root&gt;\System.Data.SQLite\SQLite3.cs</li>
      <li>&lt;root&gt;\System.Data.SQLite\UnsafeNativeMethods.cs</li>
      <li>&lt;root&gt;\System.Data.SQLite.Linq\AssemblyInfo.cs</li>
      <li>&lt;root&gt;\test\AssemblyInfo.cs</li>
      <li>&lt;root&gt;\test\app.config</li>
      <li>&lt;root&gt;\testce\AssemblyInfo.cs</li>
      <li>&lt;root&gt;\testlinq\2008\App.config</li>
      <li>&lt;root&gt;\testlinq\2010\App.config</li>
      <li>&lt;root&gt;\testlinq\Properties\AssemblyInfo.cs</li>
      <li>&lt;root&gt;\Tests\version.eagle</li>
      <li>&lt;root&gt;\tools\install\Properties\AssemblyInfo.cs</li>
    </ul>

    You'll need to update the INTEROP_BUILD_NUMBER, INTEROP_MANIFEST_VERSION,
    and INTEROP_RC_VERSION properties in the &quot;.vsprops&quot; and
    &quot;.props&quot; files, and the INTEROP_VERSION define in
    &quot;interop.h&quot;.  This version number should track the release
    versions of the System.Data.SQLite packages (i.e. [./news.wiki | 1.0.x]).
  </li>
</ol>

<a name="manual"></a>
<h2>Manual Build</h2>

<ol>
  <li>
    Complete the steps outlined in the [./build.wiki#all | All Builds] section
    (above).
  </li>

  <li>
    Open the appropriate solution for your build platform.

    <ul>
      <li>
        The &quot;SQLite.NET.2008.sln&quot; file is the top-level solution
        primarily designed for use with Visual Studio 2008 in the IDE; however,
        it may also be used from the command line with MSBuild 3.5.
      </li>

      <li>
        The &quot;SQLite.NET.2010.sln&quot; file is the top-level solution
        primarily designed for use with Visual Studio 2010 in the IDE; however,
        it may also be used from the command line with MSBuild 4.0.
      </li>

      <li>
        The &quot;SQLite.NET.2008.MSBuild.sln&quot; file is the top-level
        solution primarily designed for use with MSBuild 3.5 on the command
        line; however, it may also be used from the Visual Studio 2008 IDE.
      </li>

      <li>
        The &quot;SQLite.NET.2010.MSBuild.sln&quot; file is the top-level
        solution primarily designed for use with MSBuild 4.0 on the command
        line; however, it may also be used from the Visual Studio 2010 IDE.
      </li>
    </ul>
  </li>

  <li>
    Select the desired solution configuration (e.g. ReleaseNativeOnly) and and
    solution platform (e.g. x64), then &quot;Build->Rebuild Solution&quot;.
    Alternatively, you can select &quot;Build->Batch Build&quot;, &quot;Select
    All&quot;, and then &quot;Rebuild&quot;.
  </li>
</ol>

<a name="automated"></a>
<h2>Automated Build</h2>

<ol>
  <li>
    Complete the steps outlined in the [./build.wiki#all | All Builds] section
    (above).
  </li>

  <li>
    Make sure the &quot;&lt;root&gt;\bin&quot; and &quot;&lt;root&gt;\obj&quot;
    directories are completely free of all output files.  In theory, you should
    be able to simply delete these directories.
  </li>

  <li>Open a normal command prompt window with &quot;cmd.exe&quot;.</li>

  <li>Change the current directory to &quot;&lt;root&gt;\Setup&quot;.</li>

  <li>
    Enter the following command to build the binaries for Win32 (x86):&nbsp;
    <b>build.bat ReleaseNativeOnly Win32</b><br /><i>You may need to enter the
    command &quot;<b>setenv /x86</b>&quot; first if you are using a
    &quot;Windows SDK Command Prompt&quot; or &quot;Visual Studio Command
    Prompt&quot; window.</i>
  </li>

  <li>
    Make sure everything succeeds with no errors; the log file
    &quot;%TEMP%\System.Data.SQLite.Build_ReleaseNativeOnly_Win32_&lt;year&gt;_Unknown.log&quot;
    may be checked if any errors should occur.
  </li>

  <li>
    Enter the following command to build the binaries for x64:&nbsp;<b>build.bat
    ReleaseNativeOnly x64</b><br /><i>You may need to enter the command
    &quot;<b>setenv /x64</b>&quot; first if you are using a &quot;Windows SDK
    Command Prompt&quot; or &quot;Visual Studio Command Prompt&quot; window.</i>
  </li>

  <li>
    Make sure everything succeeds with no errors; the log file
    &quot;%TEMP%\System.Data.SQLite.Build_ReleaseNativeOnly_x64_&lt;year&gt;_Unknown.log&quot;
    may be checked if any errors should occur.
  </li>

  <li>
    Enter the following command to build the setup binaries for all supported
    build configurations (unfortunately, it is not possible to build the setup
    using the Inno Setup IDE.  It must be done using the provided command line
    tools due to its highly dynamic nature):&nbsp;<b>bake_all.bat</b>
  </li>

  <li>
    Make sure everything succeeds with no errors.  Inno Setup should produce
    &quot;success&quot; messages very similar to the following:&nbsp;
    <b>Successful compile (X.XXX sec). Resulting Setup program filename
    is:&nbsp;abc</b>
  </li>

<p>
  This agreement applies to your contribution of material to the
  System.Data.SQLite ADO.NET interfaces ("SDS") that is
  mananged by Hipp, Wyrick &amp; Company, Inc. ("Hwaci") and
  sets out the intellectual property rights you grant to Hwaci in the
  contributed material.
  The terms "contribution" and "contributed material" mean any source code,
  object code, patch, tool, sample, graphic, specification, manual,
  documentation, or any other material posted, submitted, or uploaded by
  you to the SDS project.
  The term "you" means the person identified
  and signing at the bottom of this document.  If your contribution
  is on behalf of a company, the term "you" also means the company
  identified in the signature area below.
</p>

<ol>
    <li>
      <p>
        With respect to any worldwide copyrights, or copyright applications and
        registrations, in your contribution:
        <ul>
          <li>
            You hereby assign to Hwaci joint ownership, and to the extent that
            such assignment is or becomes invalid, ineffective or unenforceable,
            you hereby grant to Hwaci a perpetual, irrevocable, non-exclusive,
            worldwide, no-charge, royalty-free, unrestricted license to exercise
            all rights under those copyrights, including the right to sublicense.
          </li>
          <li>
            You agree that both you and Hwaci can do all things in relation to your
            contribution as if each of us were the sole owners, and if one of us
            makes a derivative work of your contribution, the one who makes
            (or has made) the derivative work will be the sole owner of that
            derivative work.
          </li>
          <li>
            You agree that you will not assert any moral rights in your
            contribution against Hwaci, Hwaci's licensees or transferees, or
            any other user or consumer of your contribution.
          </li>
          <li>
            You agree that Hwaci may register a copyright in your contribution and
            exercise all ownership rights associated with it.
          </li>
          <li>
            You agree that neither you nor Hwaci has any duty to consult with,
            obtain the consent of, or pay or render an accounting to the other
            for any use or distribution of your contribution.
          </li>
        </ul>
      </p>
    </li>
    <li>
      <p>
        With respect to any patents you own, or that you can license without payment
        to any third party, and which are relevant to your contribution, you hereby
        grant to Hwaci a perpetual, irrevocable, non-exclusive, worldwide, no-charge,
        royalty-free license to
        make, have made, use, sell, offer to sell, import, and otherwise
        transfer your contribution in whole or in part, alone or in
        combination with or included in any product, work or materials arising
        out of the SDS project, and to sublicense these same rights.
      </p>
    </li>
    <li>
      <p>
        Except as set out above, you keep all right, title, and interest in your
        contribution.  The rights that you grant to Hwaci under this agreement
        are effective on the date that you first submitted your contribution to the
        SDS project, even if your submission took place before the date that
        you sign this agreement.
      </p>
    </li>
    <li>
      <p>
        You represent and warrant the following:
        <ul>
          <li>
            Your contribution is an original work and that you can legally
            grant the rights set out in this agreement.
          </li>
          <li>
            Your contribution does not, to the best of your knowledge and belief,

            or other intellectual property rights.
          </li>
          <li>
            You are authorized to sign this agreement on behalf of your

<title>Contributing To System.Data.SQLite</title>

Users are encouraged to contributed enhancements back to the System.Data.SQLite
project.  This note outlines some of the procedures for making
useful contributions.

<h2>1.0 Contributor Agreement</h2>

In order to accept your contributions, we <u>must</u> have a
[./contrib_agreement.wiki | Contributor Agreement] on file for you.  We require
this in order to maintain clear title to the System.Data.SQLite code and prevent
the introduction of code with incompatible licenses or other entanglements
that might cause legal problems for System.Data.SQLite users.  

If you do not wish to submit a Contributor Agreement, we would still
welcome your suggestions and example code, but we will not use your code
directly - we will be forced to reimplement your changes from scratch which
might take longer.

<h2>2.0 Submitting Patches</h2>

Suggested changes or bug fixes can be submitted by creating a patch
against the current source tree.  Email patches to 
<a href="mailto:drh@sqlite.org">drh@sqlite.org</a>.  Be sure to 
describe in detail what the patch does and which version of System.Data.SQLite
it is written against.  

A contributor agreement is not strictly necessary to submit a patch.
However, without a contributor agreement on file, your patch will be
used for reference only - it will not be applied to the code.  This
may delay acceptance of your patch.

Your patches or changes might not be accepted even if you do have
a contributor agreement on file.  Please do not take this personally
or as an affront to your coding ability.  Sometimes patches are rejected
because they seem to be taking the project in a direction that the
architect does not want to go.  Or, there might be an alternative
implementation of the same feature being prepared separately.

<h2>3.0 Check-in Privileges</h2>

Check-in privileges are granted on a case-by-case basis.   Your chances
of getting check-in privileges are much improved if you have a history
of submitting quality patches and/or making thoughtful posts on the
[http://www.mail-archive.com/sqlite-users@sqlite.org/ | mailing list].
A contributor agreement is, of course, a prerequisite for check-in
privileges.</p>

Contributors are asked to make all non-trivial changes on a branch.  A
System.Data.SQLite admin will review the branch and merge the changes 
into the trunk.</p>

Contributors are required to following the
[./checkin.wiki | pre-checkin checklist] prior to every checkin to
the System.Data.SQLite self-hosting repository.  This checklist is short and succinct
and should only require a few seconds to follow.  Contributors 
should print out a copy of the pre-checkin checklist and keep
it on a notecard beside their workstations, for quick reference.

Contributors should review and try to mimic the coding style
used through the rest of the System.Data.SQLite source code.  Your code should
blend in.  A third-party reader should be unable to distinguish your
code from any other code in the source corpus. 

<h2>4.0 Testing</h2>

System.Data.SQLite has a simple test harness that excercises the basic
System.Data.SQLite functions, but this is an area that needs further work.  
(Your contributions here are welcomed!)
Contributors with check-in privileges are expected to run the test harness 
on all changes they contribute, and if appropriate add new automated test 
scripts to cover their additions.

<title>Features</title>

<h2>Features</h2>

<ul>
  <li>
    Written from scratch on Visual Studio 2008 specifically for ADO.NET,
    implementing all the base classes and features recently introduced in the
    framework, including automatic transaction enlistment.
  </li>

  <li>
    Supports the Full and Compact .NET Framework, and native C/C++ development.
    100% binary compatible with the original sqlite3.dll.
  </li>

  <li>
    Full support for Mono via a &quot;managed only&quot; provider that runs
    against the official SQLite 3.6.1 or higher library.
  </li>

  <li>Full Entity Framework support (ADO.NET 3.5 SP1).</li>

  <li>
    On the Compact Framework, it is faster than SQL Server Mobile.  SQLite's
    installed size is a fraction of SQL Mobile's.  It uses less memory at
    runtime, runs queries faster, and has a smaller database file size as well.
  </li>

  <li>
    Encrypted database support.  Encrypted databases are fully encrypted and
    support both binary and cleartext password types.
  </li>

  <li>
    Visual Studio design-time Support, works with all versions of Visual Studio
    2005/2008/2010.  You can add a SQLite database to the Servers list, design
    queries with the Query Designer, drag-and-drop tables onto a Typed DataSet,
    etc.
    <br />
    <font color="red">
      Currently not included.  We are still updating the design-time support
      installer.  Due to Visual Studio licensing restrictions, the Express
      Editions can no longer be supported.
    </font>
  </li>

  <li>
    Full SQLite schema editing inside Visual Studio.  You can create/edit tables,
    views, triggers, indexes, check constraints and foreign keys.
  </li>

  <li>
    Single file redistributable (except on Compact Framework).  The core SQLite
    native code and the ADO.NET managed wrapper are combined into one mixed-mode
    assembly.
  </li>

  <li>
    Binaries included for x86, x64, Itanium, and ARM processors.
    <br />
    <font color="red">
      Itanium processor support not currently included.
    </font>
  </li>

  <li>DbProviderFactory support.</li>

  <li>
    Full support for ATTACH'ed databases.  Exposed as <i>Catalogs</i> in the
    schema.  When cloning a connection, all attached databases are automatically
    re-attached to the new connection.
  </li>

  <li>
    DbConnection.GetSchema(...) support includes <i>ReservedWords</i>,
    <i>MetaDataCollections</i>, <i>DataSourceInformation</i>, <i>DataTypes</i>,
    <i>Columns</i>, <i>Tables</i>, <i>Views</i>, <i>ViewColumns</i>,
    <i>Catalogs</i>, <i>Indexes</i>, <i>IndexColumns</i>, <i>ForeignKeys</i> and
    <i>Triggers</i>.
  </li>

  <li>
    Enhanced DbDataReader.GetSchemaTable() functionality returns catalog,
    namespace and detailed schema information even for complex queries.
  </li>

  <li>Named and unnamed parameters.</li>

  <li>
    Full UTF-8 and UTF-16 support, each with optimized pipelines into the native
    database core.
  </li>

  <li>
    Multiple simultaneous DataReaders (one DataReader per Command however).
  </li>

  <li>
    Full support for user-defined scalar and aggregate functions, encapsulated
    into an easy-to-use base class in which only a couple of overrides are
    necessary to implement new SQL functions.
  </li>

  <li>
    Full support for user-defined collating sequences, every bit as simple to
    implement as user-defined functions and uses the same base class.
  </li>

  <li>
    Full source for the entire engine and wrapper.  No copyrights.  Public
    Domain.  100% free for commercial and non-commercial use.
  </li>
</ul>

  This is a fork of the popular ADO.NET adapter for
  <a href="http://www.sqlite.org/">SQLite</a> known as System.Data.SQLite. The
  originator of System.Data.SQLite, Robert Simpson, is aware of this fork, has
  expressed his approval, and has commit privileges on the new Fossil
  repository.  The SQLite development team intends to maintain
  System.Data.SQLite moving forward.

<b>Version History</b>

<p>
    <b>1.0.77.0 - November 28, 2011</b>
</p>
<ul>
    <li>Updated to SQLite 3.7.9 <a href="http://www.sqlite.org/src/info/a499ae3835">[a499ae3835]</a>.</li>
    <li>More enhancements to the build and test automation.</li>
    <li>Plug native memory leak when closing a database connection containing a statement that cannot be finalized for some reason.</li>
    <li>The SQLite3 class should always attempt to dispose the contained SQLiteConnectionHandle, even when called via the finalizer.</li>
    <li>When compiled with DEBUG defined, emit diagnostic information related to resource cleanup to any TraceListener objects that may be registered.</li>
    <li>Stop characterizing all log messages as errors. From now on, if the errorCode is zero, the message will not be considered an error.</li>
    <li>Never attempt to configure the native logging interface if the SQLite core library has already been initialized for the process. Fix for [2ce0870fad].</li>
    <li>Allow the SQLiteLog class to be used for logging messages without having an open connection.</li>
    <li>Support building the core System.Data.SQLite assemblies using the .NET Framework 4.0 Client Profile. Fix for [566f1ad1e4].</li>
    <li>When generating the schema based on the contents of a SQLiteDataReader, skip flagging columns as unique if the data reader is holding the result of some kind of multi-table construct (e.g. a cross join) because we must allow duplicate values in that case. Fix for [7e3fa93744].</li>
    <li>When returning schema information that may be used by the .NET Framework to construct dynamic SQL, use a fake schema name (instead of null) so that the table names will be properly qualified with the catalog name (i.e. the attached database name). Partial fix for [343d392b51].</li>
    <li>Add SQLiteSourceId property to the SQLiteConnection class to return the SQLite source identifier.</li>
    <li>Add MemoryUsed and MemoryHighwater properties to the SQLiteConnection class to help determine the memory usage of SQLite.</li>
    <li>Add DateTimeKind connection string property to control the DateTimeKind of parsed DateTime values. Partial fix for [343d392b51].</li>
    <li>Improve the robustness of the SQLiteLog class when it will be initialized and unloaded multiple times.</li>
    <li>Fix the name of the interop assembly for Windows CE. Add unit tests to prevent this type of issue from happening again. Fix for [737ca4ff74].</li>
    <li>Formally support the SQL type name BOOLEAN in addition to BOOL. Fix for [544dba0a2f].</li>
    <li>Make sure the SQLiteConvert.TypeNameToDbType method is thread-safe. Fix for [84718e79fa].</li>
</ul>
<p>
    <b>1.0.76.0 - October 4, 2011</b>
</p>
<ul>
    <li>Prevent the domain unload event handler in SQLiteLog from being registered multiple times. Fix for [0d5b1ef362].</li>
    <li>Stop allowing non-default application domains to initialize the SQLiteLog class. Fix for [ac47dd230a].</li>
</ul>
<p>
    <b>1.0.75.0 - October 3, 2011</b>
</p>
<ul>
    <li>Updated to SQLite 3.7.8 <a href="http://www.sqlite.org/src/info/3e0da808d2">[3e0da808d2]</a>.</li>
    <li>More enhancements to the build system.</li>
    <li>Add official <a href="http://www.nuget.org/">NuGet</a> packages for x86 and x64.</li>
    <li>Add Changes and LastInsertRowId properties to the connection class.</li>
    <li>Support more formats when converting data from/to the DateTime type.</li>
    <li>Make all the assembly versioning attributes consistent.</li>
    <li>Add unit testing infrastructure using <a href="http://eagle.to/">Eagle</a>.</li>
    <li>Integrate all legacy unit tests, including the &quot;testlinq&quot; project, into the new test suite.</li>
    <li>Add projects to build the interop assembly statically linked to the Visual C++ runtime. Fix for [53f0c5cbf6].</li>
    <li>Add SQLITE_ENABLE_STAT2 compile-time option to the interop assembly. Fix for [74807fbf27].</li>
    <li>Fix mutex issues exposed when running the test suite with the debug version of SQLite.</li>
    <li>Fix transaction enlistment when repeated attempts are made to enlist in the same transaction. Fix for [ccfa69fc32].</li>
    <li>Support the SQLITE_FCNTL_WIN32_AV_RETRY file control to mitigate the impact of file sharing violations caused by external processes.</li>
    <li>Refactor the logging interface to be thread-safe and self-initializing.</li>
    <li>Shutdown the SQLite native interface when the AppDomain is being unloaded. Fix for [b4a7ddc83f].</li>
    <li>Support Skip operation for LINQ using OFFSET. Fix for [8b7d179c3c].</li>
    <li>Support EndsWith operation for LINQ using SUBSTR. Fix for [59edc1018b].</li>
    <li>Support all SQLite journal modes. Fix for [448d663d11].</li>
    <li>Do not throw exceptions when disposing SQLiteDataReader. Fix for [e1b2e0f769].</li>
    <li>The REAL type should be mapped to System.Double. Fix for [2c630bffa7] and [b0a5990f48].</li>
    <li>Minor optimization to GetParamValueBytes(). Fix for [201128cc88].</li>
    <li>Support the ON UPDATE, ON DELETE, and MATCH clause information when generating schema metadata for foreign keys. Partial fix for [b226147b37]. VS designer changes are not yet tested.</li>
    <li>Fix incorrect resource name for SR.resx in the mixed-mode assembly.</li>
    <li>Reduce the number of String.Compare() calls in the hot path for SQLiteCommand.ExecuteReader().</li>

<title>Support</title>

<h3>Mailing Lists</h3>

<p>
  SQLite has an active mailing list and support community and users of
  the System.Data.SQLite project available on this web site are encouraged to
  use these for support questions.
</p>

<p>
  Three separate mailing lists have been established to help support SQLite and
  System.Data.SQLite:
</p>

<ul>
  <li>
    <a href="http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-announce">
    sqlite-announce</a> - announcements of new releases or significant
    developments.
  </li>

  <li>
    <a href="http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users">
    sqlite-users</a> - general user discussion; most postings belong here.
  </li>

  <li>
    <a href="http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-dev">
    sqlite-dev</a> - developer conversations; for people who have or aspire to
    have write permission on the SQLite and/or System.Data.SQLite source code
    repositories.
  </li>
</ul>

<p>
  Most users of SQLite and/or System.Data.SQLite will want to join the
  <a href="http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-announce">
  sqlite-announce</a> list and many will want to join the
  <a href="http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users">
  sqlite-users</a> list.  The
  <a href="http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-dev">
  sqlite-dev</a> list is more specialized and appeals to a narrower audience.
  Off-site archives of the
  <a href="http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users">
  sqlite-users</a> list are available at:
</p>

<ul>
  <li>
    <a href="http://www.mail-archive.com/sqlite-users%40sqlite.org/">
    http://www.mail-archive.com/sqlite-users%40sqlite.org/</a>
  </li>

  <li>
    <a href="http://marc.info/?l=sqlite-users&r=1&w=2">
    http://marc.info/?l=sqlite-users&r=1&w=2</a>
  </li>

  <li>
    <a href="http://news.gmane.org/gmane.comp.db.sqlite.general">
    http://news.gmane.org/gmane.comp.db.sqlite.general</a>
  </li>
</ul>

<h3>Direct E-Mail</h3>

<p>
  Use the mailing list. Please do <b>not</b> send email directly
  to the authors of SQLite or System.Data.SQLite unless:
</p>

<ul>
  <li>
    You have or intend to acquire a
    <a href="http://www.sqlite.org/draft/support.html">
    professional support contract</a>.
  </li>

  <li>
    You are working on an open source project.
  </li>
</ul>

<p>
  You are welcomed to use SQLite and System.Data.SQLite in closed source,
  proprietary, and/or commercial projects and to ask questions about such use
  on the public mailing list.  But please do not ask to receive free direct
  technical support. The software is free; direct technical support is not.

<title>Test Procedures</title>

<a name="assumptions"></a>
<h2>Test Assumptions &amp; Prerequisites</h2>

<ol>
  <li>
    The string &quot;&lt;root&gt;&quot; represents the root of the source tree
    (i.e. the working check-out directory) for the System.Data.SQLite project.
  </li>

  <li>
    The string &quot;&lt;year&gt;&quot; represents the version of Visual Studio
    used (e.g. &quot;2008&quot; or &quot;2010&quot;) to build the binaries being
    tested.
  </li>

  <li>
    The string &quot;&lt;configuration&gt;&quot; represents the build
    configuration for the binaries being tested (e.g. &quot;Debug&quot; or
    &quot;Release&quot;).
  </li>

  <li>
    The string &quot;&lt;platform&gt;&quot; represents the native platform for
    the binaries being tested (e.g. &quot;Win32&quot; or &quot;x64&quot;).
  </li>

  <li>
    The string &quot;&lt;pid&gt;&quot; represents the process identifier for the
    instance of EagleShell being used to run the unit tests (e.g.
    &quot;1234&quot;).
  </li>
</ol>

<a name="procedures"></a>
<h2>Test Procedures</h2>

<p>
  Follow these steps to unit test the System.Data.SQLite (SDS) binaries.
  Unless otherwise noted, all steps need to be done in the order specified.
</p>

<p>
  First, you will need a full source check-out for the System.Data.SQLite
  project, including the
  &quot;<a href="/index.html/dir?name=Externals/Eagle">Externals\Eagle</a>&quot;
  directory.
</p>

<p>
  The binaries to test must be [./build.wiki | built] or
  [./downloads.wiki | downloaded].  If the binaries are downloaded, they must be
  placed in the appropriate build output directory (e.g.
  &quot;&lt;root&gt;\bin\&lt;year&gt;\&lt;configuration&gt;\bin&quot; for the
  separate managed and interop assemblies or
  &quot;&lt;root&gt;\bin\&lt;year&gt;\&lt;platform&gt;\&lt;configuration&gt;&quot;
  for the mixed-mode assembly).
</p>

<p>
  The new unit tests have been setup using <a href="http://eagle.to/">Eagle</a>
  and its associated unit testing framework, named &quot;EagleTest&quot;.  Eagle
  is an implementation of the <a href="http://www.tcl.tk/">Tcl</a> scripting
  language for the Common Language Runtime (CLR).  EagleTest is the unit testing
  framework for Eagle, packaged as a collection of Eagle scripts, based loosely
  on the implementation of
  <a href="http://www.tcl.tk/man/tcl8.4/TclCmd/tcltest.htm">tcltest</a>.
</p>

<a name="automated"></a>
<h2>Automated Unit Tests</h2>

<ol>
  <li>Open a normal command prompt window with &quot;cmd.exe&quot;.</li>

  <li>Change the current directory to &quot;&lt;root&gt;&quot;.</li>

  <li>
    Enter the following command to run all the unit tests against the binaries
    built with a separate managed and interop assembly:
    <b>Externals\Eagle\bin\EagleShell.exe -file Tests\all.eagle</b>
  </li>

  <li>
    Enter the following command to run all the unit tests against the binaries
    built with a mixed-mode assembly:
    <b>Externals\Eagle\bin\EagleShell.exe -initialize -runtimeOption native -file Tests\all.eagle</b>
  </li>

  <li>
    To test binaries built with MSBuild 3.5 or Visual Studio 2008 (i.e. because
    the default is to test binaries built with MSBuild 4.0 or Visual Studio
    2010) add the following command line argument right after
    &quot;Externals\Eagle\bin\EagleShell.exe&quot; in either of the above
    command lines:
    <b>-preInitialize &quot;set test_year 2008&quot;</b>
  </li>

  <li>
    To test binaries built in the &quot;Debug&quot; build configuration (i.e.
    because the default is to test binaries built in the &quot;Release&quot;
    build configuration) add the following command line argument right after
    &quot;Externals\Eagle\bin\EagleShell.exe&quot; in either of the above
    command lines:
    <b>-preInitialize &quot;set test_configuration Debug&quot;</b>
  </li>

  <li>
    Make sure all tests pass; the log file
    &quot;%TEMP%\EagleShell.exe.test.&lt;pid&gt;.log&quot; may be checked if any
    errors should occur.  EagleTest should produce &quot;success&quot; messages
    very similar to the following:<br /><br />
    PASSED: 107<br />
    TOTAL: 107<br />
    PASS PERCENTAGE: 100%<br />
    OVERALL RESULT: SUCCESS<br />
  </li>
</ol>
