      </p>
      <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>

    <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>

      <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>

** possible if the files were compiled separately.  Performance improvements
** of 5% are more are commonly seen when SQLite is compiled as a single
** translation unit.

** This file is all you need to compile SQLite.  To use SQLite in other

** the programming interface to the SQLite library.  (If you do not have 
** the "sqlite3.h" header file at hand, you will find a copy in the first
** 2679 lines past this header comment.)  Additional code files may be
** needed if you want a wrapper to interface SQLite with your choice of

** This file is an amalgamation of many separate C source files from SQLite
** version 3.4.1.  By combining all the individual C code files into this 
** single large file, the entire code can be compiled as a one translation
** unit.  This allows many compilers to do optimizations that would not be
** possible if the files were compiled separately.  Performance improvements
** of 5% are more are commonly seen when SQLite is compiled as a single
** translation unit.
**
** This file is all you need to compile SQLite.  To use SQLite in other

** the programming interface to the SQLite library.  (If you do not have 
** the "sqlite3.h" header file at hand, you will find a copy in the first
** 2702 lines past this header comment.)  Additional code files may be
** needed if you want a wrapper to interface SQLite with your choice of
** programming language.  The code for the "sqlite3" command-line shell
** is also in a separate file.  This file contains only code for the core
** SQLite library.
