<h1 align=center>SQL As Understood By SQLite</h1>

<p>SQLite understands most of the standard SQL
language.  But it does <a href="omitted.html">omit some features</a>
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 <a href="lang_keywords.html">SQL keywords</a> is 
also provided.  The SQL language syntax is described by
<a href="syntaxdiagrams.html">syntax diagrams</a>.

<p>The following syntax documentation topics are available:</p>

<h1 align="center">SQL As Understood By SQLite</h1><p><a href="lang.html">[Top]</a></p><h2>Aggregate Functions</h2>

<p>
The aggregate functions shown below are available by default.  Additional
aggregate functions written in C may be added using the 
<a href="c3ref/create_function.html">sqlite3_create_function()</a></a>
API.</p>

<p>
In any aggregate function that takes a single argument, that argument
can be preceded by the keyword DISTINCT.  In such cases, duplicate
elements are filtered before being passed into the aggregate function.
For example, the function "count(distinct X)" will return the number
of distinct values of column X instead of the total number of non-null
values in column X.

  The avg() function
  returns the average value of all non-NULL <i>X</i> within a
  group.  String and BLOB values that do not look like numbers are
  interpreted as 0.
  The result of avg() is always a floating point value as long as
  at there is at least one non-NULL input even if all
  inputs are integers.  The result of avg() is NULL if and only if
  there are no non-NULL inputs.

<a name="count"></a>
<dt><p><b>count(<i>X</i>)<br />count(*)</b></dt><dd><p>
  The count(X) function returns
  a count of the number of times
  that <i>X</i> is not NULL in a group.  The count(*) function
  (with no arguments) returns the total number of rows in the group.
</dd>
</td></tr><tr><td valign="top" align="right" width="120"><a name="groupconcat"></a>

<a name="groupconcat"></a>
<dt><p><b>group_concat(<i>X</i>)<br />group_concat(<i>X</i>,<i>Y</i>)</b></dt><dd><p>
  The group_concat() function returns
  a string which is the concatenation of
  all non-NULL values of <i>X</i>.  If parameter <i>Y</i> is present then
  it is used as the separator
  between instances of <i>X</i>.  A comma (",") is used as the separator
  if <i>Y</i> is omitted.  The order of the concatenated elements is
  arbitrary.
</dd>

max(<i>X</i>)</td><td valign="top">
<a name="maxggunc"></a>
<dt><p><b>max(<i>X</i>)</b></dt><dd><p>
  The max() aggregate function
  returns the maximum value of all values in the group.
  The maximum value is the value that would be returned last in an
  ORDER BY on the same column.  Aggregate max() returns NULL 
  if and only if there are no non-NULL values in the group.
</dd>
</td></tr><tr><td valign="top" align="right" width="120"><a name="minggunc"></a>
min(<i>X</i>)</td><td valign="top">
<a name="minggunc"></a>
<dt><p><b>min(<i>X</i>)</b></dt><dd><p>
  The min() aggregate function
  returns the minimum non-NULL value of all values in the group.
  The minimum value is the first non-NULL value that would appear
  in an ORDER BY of the column.
  Aggregate min() returns NULL if and only if there are no non-NULL
  values in the group.

<a name="sumunc"></a>
<dt><p><b>sum(<i>X</i>)<br />total(<i>X</i>)</b></dt><dd><p>
  The sum() and total() aggregate functions
  return sum of all non-NULL values in the group.
  If there are no non-NULL input rows then sum() returns
  NULL but total() returns 0.0.
  NULL is not normally a helpful result for the sum of no rows

<p> The ATTACH DATABASE statement adds another database 
file to the current <a href="c3ref/sqlite3.html">database connection</a>. 
Database files that were previously attached can be removed using
the <a href="lang_detach.html">DETACH DATABASE</a> command.

<p>Comments are not SQL commands, but can occur within the text of
SQL queries passed to <a href="c3ref/prepare.html">sqlite3_prepare_v2()</a> and related interfaces.
Comments are treated as whitespace by the parser.
Comments can begin anywhere whitespace 
can be found, including inside expressions that span multiple lines.

<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>

  <a href="c3ref/compileoption_get.html">sqlite3_compileoption_used()</a> C/C++ function.
  When the argument X to sqlite_compileoption_used(X) is a string which
  is the name of a compile-time option, this routine returns true (1) or
  false (0) depending on whether or not that option was used during the
  build.

  The sqlite_source_id() function returns a string that identifies the
  specific version of the source code that was used to build the SQLite
  library.  The string returned by sqlite_source_id() is
  the date and time that the source code was checked in followed by
  the SHA1 hash for that check-in.  This function is
  an SQL wrapper around the <a href="c3ref/libversion.html">sqlite3_sourceid()</a> C interface.

<dt><p><b>substr(<i>X</i>,<i>Y</i>,<i>Z</i>)<br />substr(<i>X</i>,<i>Y</i>)</b></dt><dd><p>
  The substr(X,Y,Z) function returns a substring of input string X that begins
  with the Y-th character and which is Z characters long.
  If Z is omitted then substr(X,Y) returns all characters through the end
  of the string X beginning with the Y-th.
  The left-most character of X is number 1.  If Y is negative
  then the first character of the substring is found by counting from the
  right rather than the left.  If Z is negative then
  the abs(Z) characters preceding the Y-th character are returned.
  If X is a string then characters indices refer to actual UTF-8 
  characters.  If X is a BLOB then the indices refer to bytes.

<a name="unicode"></a>
<dt><p><b>unicode(<i>X</i>)</b></dt><dd><p>
  The unicode(X) function returns the numeric unicode code point corresponding to

  The unlikely(X) function returns the argument X unchanged.
  The unlikely(X) function is a no-op that the code generator
  optimizes away so that it consumes no CPU cycles at
  run-time (that is, during calls to <a href="c3ref/step.html">sqlite3_step()</a>).
  The purpose of the unlikely(X) function is to provide a hint
  to the query planner that the argument X is a boolean value
  that is usually not true. The unlikely(X) function is equivalent
  to <a href="lang_corefunc.html#likelihood">likelihood</a>(X, 0.0625).

  The zeroblob(N) function returns a BLOB consisting of N bytes of 0x00.
  SQLite manages these zeroblobs very efficiently.  Zeroblobs can be used to
  reserve space for a BLOB that is later written using 
  <a href="c3ref/blob_open.html">incremental BLOB I/O</a>.
  This SQL function is implemented using the <a href="c3ref/result_blob.html">sqlite3_result_zeroblob()</a>
  routine from the C/C++ interface.

<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 table column
names and/or expressions that are used for the index key.
If the optional WHERE clause is included, then the index is a "<a href="partialindex.html">partial index</a>".

<h3>The RAISE() function</h3>

<p>A special SQL function RAISE() may be used within a trigger-program,
with the following syntax</p> 

<p><b><a href="syntax/raise-function.html">raise-function:</a></b></p><blockquote>
<p><b><a href="syntax/raise-function.html">raise-function:</a></b></p><div class='imgcontainer'>
 <img alt="syntax diagram raise-function" src="images/syntax/raise-function.gif"></img>
 </blockquote>
 </div>


<p>When one of RAISE(ROLLBACK,...), RAISE(ABORT,...) or RAISE(FAIL,...)
is called during trigger-program
execution, the specified <a href="lang_conflict.html">ON CONFLICT</a> processing is performed
the current query terminates.
An error code of <a href="rescode.html#constraint">SQLITE_CONSTRAINT</a> is returned to the application,

<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 <a href="lang_select.html">SELECT</a> in place of a table name.

<h3>Optional LIMIT and ORDER BY clauses</h3>

<p>If SQLite is compiled with the <a href="compile.html#enable_update_delete_limit">SQLITE_ENABLE_UPDATE_DELETE_LIMIT</a>
compile-time option, then the syntax of the DELETE statement is
extended by the addition of optional ORDER BY and LIMIT clauses:</p>

 </blockquote>
 </div>


<p>If a DELETE statement has a LIMIT clause, the maximum number of rows that
will be deleted is found by evaluating the accompanying expression and casting
it to an integer value. If the result of the evaluating the LIMIT clause
cannot be losslessly converted to an integer value, it is an error. A 
negative LIMIT value is interpreted as "no limit". If the DELETE statement

<p>The DROP INDEX statement removes an index added
with the <a href="lang_createindex.html">CREATE INDEX</a> statement.  The index is completely removed from
the disk.  The only way to recover the index is to reenter the
appropriate <a href="lang_createindex.html">CREATE INDEX</a> command.</p>

<p>The DROP TRIGGER statement removes a trigger created by the 
<a href="lang_createtrigger.html">CREATE TRIGGER</a> statement. Once removed, the trigger definition is no
longer present in the sqlite_master (or sqlite_temp_master) table and is
not fired by any subsequent INSERT, UPDATE or DELETE statements.

<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>

A literal value represents a constant.
Literal values may be integers, floating point numbers, strings,
BLOBs, or NULLs.
<p>
The syntax for integer and floating point literals (collectively
"numeric literals") is shown by the following diagram:</p>

<p><b><a href="syntax/numeric-literal.html">numeric-literal:</a></b></p><blockquote>
<p><b><a href="syntax/numeric-literal.html">numeric-literal:</a></b></p><div class='imgcontainer'>
 <img alt="syntax diagram numeric-literal" src="images/syntax/numeric-literal.gif"></img>
 </blockquote>
 </div>


<p>
If a numeric literal has a decimal point or an exponentiation
clause or if its magnitude is less than -9223372036854775808 or
greater than 9223372036854775807, then it is a floating point literal.
Otherwise is it is an  integer literal.

<div class=nosearch><h1 align="center">SQL As Understood By SQLite</h1><p><a href="lang.html">[Top]</a></p><h2>INDEXED BY</h2></div>
<p>The INDEXED BY phrase forces the <a href="optoverview.html">SQLite query planner</a> to use a
particular named index on a <a href="lang_delete.html">DELETE</a>, <a href="lang_select.html">SELECT</a>, or <a href="lang_update.html">UPDATE</a> statement.
The INDEXED BY phrase is an SQLite extension and
is not portable to other SQL database engines.</p>

<p><b><a href="syntax/qualified-table-name.html">qualified-table-name:</a></b>
<button id='x1435' onclick='hideorshow("x1435","x1436")'>hide</button></p>
 <blockquote id='x1436'>
 <div id='x1436' class='imgcontainer'>
 <img alt="syntax diagram qualified-table-name" src="images/syntax/qualified-table-name.gif" />
</blockquote>
</div>


<p>The "INDEXED BY <span class='yyterm'>index-name</span>" phrase specifies 
that the named index
must be used in order to look up values on the preceding table.
If <span class='yyterm'>index-name</span> does not exist or cannot be used 
for the query, then the preparation of the SQL statement fails.

<div class=nosearch><h1 align="center">SQL As Understood By SQLite</h1><p><a href="lang.html">[Top]</a></p><h2>SQLite Keywords</h2></div></DIV>

<p>The SQL standard specifies a huge number of keywords which may not
be used as the names of tables, indices, columns, databases, user-defined
functions, collations, virtual table modules, or any other named object.
The list of keywords is so long that few people can remember them all.
For most SQL code, your safest bet is to never use any English language
word as the name of a user-defined object.</p>

<div class=nosearch><h1 align="center">SQL As Understood By SQLite</h1><p><a href="lang.html">[Top]</a></p><h2>Database Object Name Resolution</h2></div>

<p>
  In SQLite, a database object (a table, index, trigger or view) is identified
  by the name of the object and the name of the database that it resides in. 
  Database objects may reside in the main database, the temp database, or in
  an <a href="lang_attach.html">attached database</a>.

<p> SAVEPOINTs are a method of creating transactions, similar to
<a href="lang_transaction.html">BEGIN</a> and <a href="lang_transaction.html">COMMIT</a>, except that the SAVEPOINT and RELEASE commands
are named and may be nested.</p>

<p> The SAVEPOINT command starts a new transaction with a name.

<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.  A SELECT statement does not make
any changes to the database.

<p>The "<a href="syntax/select-stmt.html">select-stmt</a>" syntax diagram above attempts to show as much of the
SELECT statement syntax as possible in a single diagram, because some readers
find that helpful.  The following "<a href="syntax/factored-select-stmt.html">factored-select-stmt</a>" is an alternative
syntax diagrams that expresses the same syntax but tries to break the syntax 
down into smaller chunks.

<p>In a compound SELECT, all the constituent SELECTs must return the same 
number of result columns. As the components of a compound SELECT must
be simple SELECT statements, they may not contain <a href="lang_select.html#orderby">ORDER BY</a> or <a href="lang_select.html#limitoffset">LIMIT</a> clauses.
<a href="lang_select.html#orderby">ORDER BY</a> and <a href="lang_select.html#limitoffset">LIMIT</a> clauses may only occur at the end of the entire compound
SELECT, and then only if the final element of the compound is not a <a href="lang_select.html#values">VALUES</a> clause.

<h3>Optional LIMIT and ORDER BY Clauses</h3>

<p>If SQLite is built with the <a href="compile.html#enable_update_delete_limit">SQLITE_ENABLE_UPDATE_DELETE_LIMIT</a>
compile-time option then the syntax of the UPDATE statement is extended
with optional ORDER BY and LIMIT clauses as follows:</p>

<p><b><a href="syntax/update-stmt-limited.html">update-stmt-limited:</a></b></p><blockquote>
<p><b><a href="syntax/update-stmt-limited.html">update-stmt-limited:</a></b></p><div class='imgcontainer'>
 <img alt="syntax diagram update-stmt-limited" src="images/syntax/update-stmt-limited.gif"></img>
 </blockquote>
 </div>


<p>If an UPDATE statement has a LIMIT clause, the maximum number of rows that
will be updated is found by evaluating the accompanying expression and casting
it to an integer value. A negative value is interpreted as "no limit".

<p>If the LIMIT expression evaluates to non-negative value <i>N</i> and the

<p>Common Table Expressions or CTEs act like temporary <a href="lang_createview.html">views</a> that exist
only for the duration of a single SQL statement.  There are two kinds of
common table expressions: "ordinary" and "recursive". Ordinary 
common table expressions are helpful for making
queries easier to understand by factoring

<p>To put it another way, a recursive common table expression must
look like the following:

<p><b><a href="syntax/recursive-cte.html">recursive-cte:</a></b>
<button id='x1171' onclick='hideorshow("x1171","x1172")'>hide</button></p>
 <blockquote id='x1172'>

 <img alt="syntax diagram cte-table-name" src="images/syntax/cte-table-name.gif" />
</blockquote>
</blockquote>
</div>
</div>


<p>Call the table named by the <a href="syntax/cte-table-name.html">cte-table-name</a> in a recursive
common table expression the "recursive table".
In the <a href="syntax/recursive-cte.html">recursive-cte</a> bubble diagram above, the recursive
table must appear exactly once in the FROM clause of the 
<span class='yyterm'>recursive-select</span>

    <p>The "PRAGMA cache_spill=<i>boolean</i>" form of this pragma applies
    across all databases attached to the database connection.  But the
    "PRAGMA cache_spill=<i>N</i>" form of this statement only applies to
    the "main" schema or whatever other schema is specified as part of the

<h _id=pragma_case_sensitive_like style="display:none"> PRAGMA case_sensitive_like</h><hr>
    <p><b>PRAGMA case_sensitive_like = </b><i>boolean</i><b>;</b></p>
    <p>The default behavior of the <a href="lang_expr.html#like">LIKE</a> operator is to ignore case
    for ASCII characters. Hence, by default <b>'a' LIKE 'A'</b> is
    true.  The case_sensitive_like pragma installs a new application-defined
    LIKE function that is either case sensitive or insensitive depending
    on the value of the case_sensitive_like pragma.
    When case_sensitive_like is disabled, the default LIKE behavior is
    expressed.  When case_sensitive_like is enabled, case becomes
    significant.  So, for example,
    <b>'a' LIKE 'A'</b> is false but <b>'a' LIKE 'a'</b> is still true.</p>

    <p>This pragma uses <a href="c3ref/create_function.html">sqlite3_create_function()</a> to overload the
    LIKE and GLOB functions, which may override previous implementations
    of LIKE and GLOB registered by the application.  This pragma
    only changes the behavior of the SQL <a href="lang_expr.html#like">LIKE</a> operator.  It does not
    change the behavior of the <a href="c3ref/strlike.html">sqlite3_strlike()</a> C-language interface,
    which is always case insensitive.</p>

    <p><b>PRAGMA cell_size_check
       <br>PRAGMA cell_size_check = </b><i>boolean</i><b>;</b></p>
    <p>The cell_size_check pragma enables or disables additional sanity
    checking on database b-tree pages as they are initially read from disk.
    With cell size checking enabled, database corruption is detected earlier
    and is less likely to "spread".  However, there is a small performance
    hit for doing the extra checks and so cell size checking is turned off
    by default.

    <p>Query or change the fullfsync flag for <a href="wal.html#ckpt">checkpoint</a> operations.
    If this flag is set, then the F_FULLFSYNC syncing method is used
    during checkpoint operations on systems that support F_FULLFSYNC. 
    The default value of the checkpoint_fullfsync flag
    is off.  Only Mac OS-X supports F_FULLFSYNC.</p>

    <p>If the <a href="pragma.html#pragma_fullfsync">fullfsync</a> flag is set, then the F_FULLFSYNC syncing
    method is used for all sync operations and the checkpoint_fullfsync

  <p>This pragma only operates on the single database specified prior
  to the pragma name (or on the "main" database if no database is specified.)
  There is no way to change the journal size limit on all attached databases
  using a single PRAGMA statement.  The size limit must be set separately for
  each attached database.

    <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 not be
    readable or writable by versions of SQLite prior to 3.3.0.</p>

    <p>When the legacy_file_format pragma is issued with no argument,
    it returns the setting of the flag.  This pragma does <u>not</u> tell
    which file format the current database is using; it tells what format
    will be used by any newly created databases.</p>

    <p>The legacy_file_format pragma is initialized to OFF when an existing
    database in the newer file format is first opened.</p>

    <p>The size of the memory-mapped I/O region cannot be changed while
       the memory-mapped I/O region is in active use, to avoid unmapping
       memory out from under running SQL statements.  For this reason,
       the mmap_size pragma may be a no-op if the prior mmap_size is non-zero
       and there are other SQL statements running concurrently on the same
       <a href="c3ref/sqlite3.html">database connection</a>.</p>

    <p>Query or set the page size of the database. The page
    size must be a power of two between 512 and 65536 inclusive.
    </p>

    <p>When a new database is created, SQLite assigned a page size to
    the database based on platform and filesystem.  For many years,
    the default page size was almost always 1024 bytes, but beginning
    with SQLite <a href="releaselog/3_12_0.html">version 3.12.0</a> in 2016, the default page size increased
    to 4096.

    <p>The page_size pragma will only cause an immediate change in the
    page size if it is issued while the database is still empty (prior 
    to the first CREATE statement) and if the database is not in
    <a href="wal.html">WAL mode</a>.  If the page_size pragma is
    <p>The page_size pragma will only set in the
    page size if it is issued before any other SQL statements that
    cause I/O against the database file.
    SQL statements that cause I/O against the database file include
    "CREATE", "SELECT", "BEGIN IMMEDIATE", and "PRAGMA journal_mode=WAL".
    If the page_size pragma is
    used to specify a new page size just prior to
    running the <a href="lang_vacuum.html">VACUUM</a> command and if the database is not in
    <a href="wal.html">WAL journal mode</a> then <a href="lang_vacuum.html">VACUUM</a> will change the page
    size to the new value.</p>

    <p>The <a href="compile.html#default_page_size">SQLITE_DEFAULT_PAGE_SIZE</a> compile-time option can be used
    to change the default page size assigned to new databases.

    <p>If SQLite has been compiled with the <a href="compile.html#debug">SQLITE_DEBUG</a> compile-time
    option, then the parser_trace pragma can be used to turn on tracing
    for the SQL parser used internally by SQLite.
    This feature is used for debugging SQLite itself.</p>

    
    <p style='background-color: #f0e0ff;'>

    <p>The pragma is like <a href="pragma.html#pragma_integrity_check">integrity_check</a> except that it does not verify
    UNIQUE and NOT NULL constraints and does not verify
    that index content matches table content.  By skipping UNIQUE and NOT NULL
    and index consistency checks, quick_check is able to run much faster than
    integrity_check.  Otherwise the two pragmas are the same.

<h1 id="section_1">1. Introduction</h1>
<h1 id="introduction"><span>1. </span>Introduction</h1>

<p>A virtual table is an object that is registered with an open SQLite
<a href="c3ref/sqlite3.html">database connection</a>. From the perspective of an SQL statement,
the virtual table object looks like any other table or view. 
But behind the scenes, queries and updates on a virtual table
invoke callback methods of the virtual table object instead of
reading and writing on the database file.

interfaces that are accessible from SQL statements as if they were
tables. SQL statements can do almost anything to a
virtual table that they can do to a real table, with the following

<li> One cannot run <a href="lang_altertable.html">ALTER TABLE ... ADD COLUMN</a>

read-only tables. Or some virtual table implementations might allow

<h2 id="section_1_1">1.1. Usage</h2>
<h2 id="usage"><span>1.1. </span>Usage</h2>

<p>A virtual table is created using a <a href="lang_createvtab.html">CREATE VIRTUAL TABLE</a> statement.

<p><b><a href="syntax/create-virtual-table-stmt.html">create-virtual-table-stmt:</a></b>
<button id='x1475' onclick='hideorshow("x1475","x1476")'>hide</button></p>
 <blockquote id='x1476'>
 <div id='x1476' class='imgcontainer'>
 <img alt="syntax diagram create-virtual-table-stmt" src="images/syntax/create-virtual-table-stmt.gif" />
</blockquote>
</div>


<p>The CREATE VIRTUAL TABLE statement creates a new table
</p><p>The CREATE VIRTUAL TABLE statement creates a new table
called <span class='yyterm'>table-name</span> derived from the class
class <span class='yyterm'>module-name</span>.  The <span class='yyterm'>module-name</span>
is the name that is registered for the virtual table by
the <a href="c3ref/create_module.html">sqlite3_create_module()</a> interface.

<blockquote><pre>
   CREATE VIRTUAL TABLE tablename USING modulename;
</pre></blockquote>
</p><div class="codeblock"><pre>CREATE VIRTUAL TABLE tablename USING modulename;
</pre></div>

<p>One can also provide comma-separated arguments to the module following 
the module name:

<blockquote><pre>
   CREATE VIRTUAL TABLE tablename USING modulename(arg1, arg2, ...);
</pre></blockquote>
</p><div class="codeblock"><pre>CREATE VIRTUAL TABLE tablename USING modulename(arg1, arg2, ...);
</pre></div>

<p>The format of the arguments to the module is very general. Each 
<span class='yyterm'>module-argument</span>
may contain keywords, string literals, identifiers, numbers, and 
punctuation. Each <span class='yyterm'>module-argument</span> is passed as 
written (as text) into the
<a href="vtab.html#xcreate">constructor method</a> of the virtual table implementation 
when the virtual 
table is created and that constructor is responsible for parsing and 
interpreting the arguments. The argument syntax is sufficiently general 
that a virtual table implementation can, if it wants to, interpret its
arguments as <a href="lang_createtable.html#tablecoldef">column definitions</a> in an ordinary <a href="lang_createtable.html">CREATE TABLE</a> statement. 
The implementation could also impose some other interpretation on the 
arguments.

</p><p>Once a virtual table has been created, it can be used like any other 
table with the exceptions noted above and imposed by specific virtual
table implementations. A virtual table is destroyed using the ordinary
<a href="lang_droptable.html">DROP TABLE</a> syntax.

<h3 id="section_1_1_1">1.1.1. Temporary virtual tables</h3>
</p><h3 id="temporary_virtual_tables"><span>1.1.1. </span>Temporary virtual tables</h3>

<p>There is no "CREATE TEMP VIRTUAL TABLE" statement.  To create a
temporary virtual table, add the "temp" schema
before the virtual table name.

<blockcuqote><pre>
   CREATE VIRTUAL TABLE <b>temp.</b>tablename USING module(arg1, ...);
</pre></blockquote>
</p><div class="codeblock"><pre>CREATE VIRTUAL TABLE <b>temp.</b>tablename USING module(arg1, ...);
</pre></div>

<h3 id="section_1_1_2">1.1.2. Eponymous virtual tables</h3>
<h3 id="eponymous_virtual_tables"><span>1.1.2. </span>Eponymous virtual tables</h3>

<p>Some virtual tables exist automatically in the "main" schema of
every database connection in which their
module is registered, even without a <a href="lang_createvtab.html">CREATE VIRTUAL TABLE</a> statement.
Such virtual tables are called "eponymous virtual tables".
To use an eponymous virtual table, simply use the 
module name as if it were a table.
Eponymous virtual tables exist in the "main" schema only, so they will
not work if prefixed with a different schema name.

<p>An example of an eponymous virtual table is the <a href="dbstat.html">dbstat virtual table</a>.
</p><p>An example of an eponymous virtual table is the <a href="dbstat.html">dbstat virtual table</a>.
To use the dbstat virtual table as an eponymous virtual table, 
simply query against the "dbstat"
module name, as if it were an ordinary table.  (Note that SQLite
must be compiled with the <a href="compile.html#enable_dbstat_vtab">SQLITE_ENABLE_DBSTAT_VTAB</a> option to include
the dbstat virtual table in the build.)

<blockquote><pre>
   SELECT * FROM dbstat;
</pre></blockquote>
</p><div class="codeblock"><pre>SELECT * FROM dbstat;
</pre></div>

<p>A virtual table is eponymous if its <a href="vtab.html#xcreate">xCreate</a> method is the exact same
function as the <a href="vtab.html#xconnect">xConnect</a> method, or if the <a href="vtab.html#xcreate">xCreate</a> method is NULL.
The <a href="vtab.html#xcreate">xCreate</a> method is called when a virtual table is first created
using the <a href="lang_createvtab.html">CREATE VIRTUAL TABLE</a> statement.  The <a href="vtab.html#xconnect">xConnect</a> method whenever
a database connection attaches to or reparses a schema. When these two methods
are the same, that indicates that the virtual table has no persistent
state that needs to be created and destroyed.

<a name="epoonlyvtab"></a>

<h3 id="section_1_1_3">1.1.3. Eponymous-only virtual tables</h3>
</p><h3 id="eponymous_only_virtual_tables"><span>1.1.3. </span>Eponymous-only virtual tables</h3>
<p>If the <a href="vtab.html#xcreate">xCreate</a> method is NULL, then
<a href="lang_createvtab.html">CREATE VIRTUAL TABLE</a> statements are prohibited for that virtual table,
and the virtual table is an "eponymous-only virtual table".
Eponymous-only virtual tables are useful as 
<a href="vtab.html#tabfunc2">table-valued functions</a>.

<p>
</p><p>
Note that SQLite versions prior to 3.9.0 did not check the xCreate method
for NULL before invoking it.  So if an eponymous-only virtual table is
registered with SQLite version 3.8.11.1 or earlier and a <a href="lang_createvtab.html">CREATE VIRTUAL TABLE</a>
command is attempted against that virtual table module, a jump to a NULL
pointer will occur, resulting in a crash.

<h2 id="section_1_2">1.2. Implementation</h2>
</p><h2 id="implementation"><span>1.2. </span>Implementation</h2>

<p>Several new C-level objects are used by the virtual table implementation:

<blockquote><pre>
  typedef struct sqlite3_vtab sqlite3_vtab;
  typedef struct sqlite3_index_info sqlite3_index_info;
  typedef struct sqlite3_vtab_cursor sqlite3_vtab_cursor;
  typedef struct sqlite3_module sqlite3_module;
</pre></blockquote>
</p><div class="codeblock"><pre>typedef struct sqlite3_vtab sqlite3_vtab;
typedef struct sqlite3_index_info sqlite3_index_info;
typedef struct sqlite3_vtab_cursor sqlite3_vtab_cursor;
typedef struct sqlite3_module sqlite3_module;
</pre></div>

<p>The <a href="c3ref/module.html">sqlite3_module</a> structure defines a module object used to implement
a virtual table. Think of a module as a class from which one can 
construct multiple virtual tables having similar properties. For example,
one might have a module that provides read-only access to 
comma-separated-value (CSV) files on disk. That one module can then be
used to create several virtual tables where each virtual table refers
to a different CSV file.

<p>The module structure contains methods that are invoked by SQLite to
</p><p>The module structure contains methods that are invoked by SQLite to
perform various actions on the virtual table such as creating new
instances of a virtual table or destroying old ones, reading and
writing data, searching for and deleting, updating, or inserting rows. 
The module structure is explained in more detail below.

<p>Each virtual table instance is represented by an <a href="c3ref/vtab.html">sqlite3_vtab</a> structure. 
</p><p>Each virtual table instance is represented by an <a href="c3ref/vtab.html">sqlite3_vtab</a> structure. 
The sqlite3_vtab structure looks like this:

<blockquote><pre>
  struct sqlite3_vtab {
    const sqlite3_module *pModule;
    int nRef;
    char *zErrMsg;
  };
</pre></blockquote>
</p><div class="codeblock"><pre>struct sqlite3_vtab {
  const sqlite3_module *pModule;
  int nRef;
  char *zErrMsg;
};
</pre></div>

<p>Virtual table implementations will normally subclass this structure 
to add additional private and implementation-specific fields. 
The nRef field is used internally by the SQLite core and should not 
be altered by the virtual table implementation. The virtual table 
implementation may pass error message text to the core by putting 
an error message string in zErrMsg.
Space to hold this error message string must be obtained from an
SQLite memory allocation function such as <a href="c3ref/mprintf.html">sqlite3_mprintf()</a> or
<a href="c3ref/free.html">sqlite3_malloc()</a>.
Prior to assigning a new value to zErrMsg, the virtual table 
implementation must free any preexisting content of zErrMsg using 
<a href="c3ref/free.html">sqlite3_free()</a>. Failure to do this will result in a memory leak. 
The SQLite core will free and zero the content of zErrMsg when it 
delivers the error message text to the client application or when 
it destroys the virtual table. The virtual table implementation only 
needs to worry about freeing the zErrMsg content when it overwrites 
the content with a new, different error message.

<p>The <a href="c3ref/vtab_cursor.html">sqlite3_vtab_cursor</a> structure represents a pointer to a specific
</p><p>The <a href="c3ref/vtab_cursor.html">sqlite3_vtab_cursor</a> structure represents a pointer to a specific
row of a virtual table. This is what an sqlite3_vtab_cursor looks like:

<blockquote><pre>
  struct sqlite3_vtab_cursor {
    sqlite3_vtab *pVtab;
  };
</pre></blockquote>
</p><div class="codeblock"><pre>struct sqlite3_vtab_cursor {
  sqlite3_vtab *pVtab;
};
</pre></div>

<p>Once again, practical implementations will likely subclass this 
structure to add additional private fields.

</p><p>Before a <a href="lang_createvtab.html">CREATE VIRTUAL TABLE</a> statement can be run, the module 
specified in that statement must be registered with the database 
connection. This is accomplished using either of the <a href="c3ref/create_module.html">sqlite3_create_module()</a>
or <a href="c3ref/create_module.html">sqlite3_create_module_v2()</a> interfaces:

<blockquote><pre>
  int sqlite3_create_module(
    sqlite3 *db,               /* SQLite connection to register module with */
    const char *zName,         /* Name of the module */
    const sqlite3_module *,    /* Methods for the module */
    void *                     /* Client data for xCreate/xConnect */
  );
  int sqlite3_create_module_v2(
    sqlite3 *db,               /* SQLite connection to register module with */
    const char *zName,         /* Name of the module */
    const sqlite3_module *,    /* Methods for the module */
    void *,                    /* Client data for xCreate/xConnect */
    void(*xDestroy)(void*)     /* Client data destructor function */
  );
</pre></blockquote>
</p><div class="codeblock"><pre>int sqlite3_create_module(
  sqlite3 *db,               /* SQLite connection to register module with */
  const char *zName,         /* Name of the module */
  const sqlite3_module *,    /* Methods for the module */
  void *                     /* Client data for xCreate/xConnect */
);
int sqlite3_create_module_v2(
  sqlite3 *db,               /* SQLite connection to register module with */
  const char *zName,         /* Name of the module */
  const sqlite3_module *,    /* Methods for the module */
  void *,                    /* Client data for xCreate/xConnect */
  void(*xDestroy)(void*)     /* Client data destructor function */
);
</pre></div>

<p>The <a href="c3ref/create_module.html">sqlite3_create_module()</a> and <a href="c3ref/create_module.html">sqlite3_create_module_v2()</a>
routines associates a module name with 
an <a href="c3ref/module.html">sqlite3_module</a> structure and a separate client data that is specific 
to each module.  The only difference between the two create_module methods
is that the _v2 method includes an extra parameter that specifies a
destructor for client data pointer.  The module structure is what defines
the behavior of a virtual table.  The module structure looks like this:

<blockquote><pre>

    int iVersion;

<p>Prior to SQLite <a href="releaselog/3_6_17.html">version 3.6.17</a>, the virtual table mechanism assumes 
that each <a href="c3ref/sqlite3.html">database connection</a> kept
its own copy of the database schema. Hence, the virtual table mechanism
could not be used in a database that has <a href="sharedcache.html">shared cache mode</a> enabled. 
The <a href="c3ref/create_module.html">sqlite3_create_module()</a> interface would return an error if 
<a href="sharedcache.html">shared cache mode</a> is enabled.  That restriction was relaxed
beginning with SQLite <a href="releaselog/3_6_17.html">version 3.6.17</a>.

<p>The xCreate method is called to create a new instance of a virtual table

<a href="c3ref/create_module.html">sqlite3_create_module_v2()</a> call that registered the 
<a href="c3ref/module.html">virtual table module</a>. 
The argv parameter is an array of argc pointers to null terminated strings. 
The first string, argv[0], is the name of the module being invoked.   The
module name is the name provided as the second argument to 
<a href="c3ref/create_module.html">sqlite3_create_module()</a> and as the argument to the USING clause of the

The second, argv[1], is the name of the database in which the new virtual table is being created. The database name is "main" for the primary database, or
"temp" for TEMP database, or the name given at the end of the <a href="lang_attach.html">ATTACH</a>
statement for attached databases.  The third element of the array, argv[2], 
is the name of the new virtual table, as specified following the TABLE

method <u>must</u> invoke <a href="c3ref/declare_vtab.html">sqlite3_declare_vtab()</a> to tell the SQLite 
core about the columns and datatypes in the virtual table. 
The <a href="c3ref/declare_vtab.html">sqlite3_declare_vtab()</a> API has the following prototype:

<blockquote><pre>
    int sqlite3_declare_vtab(sqlite3 *db, const char *zCreateTable)
</pre></blockquote>
</p><div class="codeblock"><pre>int sqlite3_declare_vtab(sqlite3 *db, const char *zCreateTable)
</pre></div>

<p>The first argument to <a href="c3ref/declare_vtab.html">sqlite3_declare_vtab()</a> must be the same 
<a href="c3ref/sqlite3.html">database connection</a> pointer as the first parameter to this method.

UTF-8 string that contains a well-formed <a href="lang_createtable.html">CREATE TABLE</a> statement that 
defines the columns in the virtual table and their data types. 
The name of the table in this CREATE TABLE statement is ignored, 
as are all constraints. Only the column names and datatypes matter.
The CREATE TABLE statement string need not to be 
held in persistent memory.  The string can be
deallocated and/or reused as soon as the <a href="c3ref/declare_vtab.html">sqlite3_declare_vtab()</a>
routine returns.

If not successful, the <a href="c3ref/vtab.html">sqlite3_vtab</a> structure must not be allocated. 
An error message may optionally be returned in *pzErr if unsuccessful.
Space to hold the error message string must be allocated using
an SQLite memory allocation function like 
<a href="c3ref/free.html">sqlite3_malloc()</a> or <a href="c3ref/mprintf.html">sqlite3_mprintf()</a> as the SQLite core will

If the xCreate method is omitted (left as a NULL pointer) then the
virtual table is an <a href="vtab.html#epoonlyvtab">eponymous-only virtual table</a>.  New instances of
the virtual table cannot be created using <a href="lang_createvtab.html">CREATE VIRTUAL TABLE</a> and the
virtual table can only be used via its module name.
Note that SQLite versions prior to 3.9.0 do not understand
eponymous-only virtual tables and will segfault if an attempt is made
to <a href="lang_createvtab.html">CREATE VIRTUAL TABLE</a> on an eponymous-only virtual table because
the xCreate method was not checked for null.

<p>
</p><p>
If the xCreate method is the exact same pointer as the <a href="vtab.html#xconnect">xConnect</a> method,
that indicates that the virtual table does not need to initialize backing
store.  Such a virtual table can be used as an <a href="vtab.html#epovtab">eponymous virtual table</a>
or as a named virtual table using <a href="lang_createvtab.html">CREATE VIRTUAL TABLE</a> or both.

<h3 id="section_2_1_1">2.1.1. Hidden columns in virtual tables</h3>
</p><h3 id="hidden_columns_in_virtual_tables"><span>2.1.1. </span>Hidden columns in virtual tables</h3>
<p>If a column datatype contains the special keyword "HIDDEN"
(in any combination of upper and lower case letters) then that keyword
it is omitted from the column datatype name and the column is marked 
as a hidden column internally. 
A hidden column differs from a normal column in three respects:

<p>
<ul>
</p><p>
</p><ul>
<li> Hidden columns are not listed in the dataset returned by

</li><li> Hidden columns are not included in the implicit column-list 
     used by an <a href="lang_insert.html">INSERT</a> statement that lacks an explicit column-list.

</pre></blockquote>
</p><div class="codeblock"><pre>CREATE TABLE x(a HIDDEN VARCHAR(12), b INTEGER, c INTEGER Hidden);

<p>A <a href="vtab.html">virtual table</a> that contains <a href="vtab.html#hiddencol">hidden columns</a> can be used like
a table-valued function in the FROM clause of a <a href="lang_select.html">SELECT</a> statement.
The arguments to the table-valued function become constraints on 
the HIDDEN columns of the virtual table.

<p>For example, the "generate_series" extension (located in the

implements an <a href="vtab.html#epovtab">eponymous virtual table</a> with the following schema:

<blockquote><pre>
CREATE TABLE generate_series(
</p><div class="codeblock"><pre>CREATE TABLE generate_series(
  value,
  start HIDDEN,
  stop HIDDEN,
  step HIDDEN
);
</pre></blockquote>
</pre></div>

<p>The <a href="vtab.html#xbestindex">sqlite3_module.xBestIndex</a> method in the implementation of this
table checks for equality constraints against the HIDDEN columns, and uses
those as input parameters to determine the range of integer "value" outputs
to generate.  Reasonable defaults are used for any unconstrained columns.
For example, to list all integers between 5 and 50:

<blockquote><pre>
SELECT value FROM generate_series(5,50);
</pre></blockquote>
</p><div class="codeblock"><pre>SELECT value FROM generate_series(5,50);
</pre></div>

<p>The previous query is equivalent to the following:

<blockquote><pre>
SELECT value FROM generate_series WHERE start=5 AND stop=50;
</pre></blockquote>
</p><div class="codeblock"><pre>SELECT value FROM generate_series WHERE start=5 AND stop=50;
</pre></div>

<p>Arguments on the virtual table name are matched to <a href="vtab.html#hiddencol">hidden columns</a>
in order.  The number of arguments can be less than the
number of hidden columns, in which case the latter hidden columns are
unconstrained.  However, an error results if there are more arguments
than there are hidden columns in the virtual table.

<p>Beginning with SQLite <a href="releaselog/3_14.html">version 3.14.0</a>, the CREATE TABLE statement that

NOT NULL and all columns for each row must be collectively unique.

<h2 id="section_2_3">2.3. The xBestIndex Method</h2>
</p><h2 id="the_xbestindex_method"><span>2.3. </span>The xBestIndex Method</h2>

<p>SQLite uses the xBestIndex method of a virtual table module to determine
the best way to access the virtual table. 
The xBestIndex method has a prototype like this:

</p><div class="codeblock"><pre>int (*xBestIndex)(sqlite3_vtab *pVTab, sqlite3_index_info*);

The xBestIndex method fills out other fields of this structure which

version of the SQLite library in use is greater than or equal to appropriate
version - perhaps comparing the value returned from <a href="c3ref/libversion.html">sqlite3_libversion_number()</a>
against constants 3008002, 3009000, and/or 3010000. The result of attempting 
to access these fields in an sqlite3_index_info structure created by an

<p>The SQLite core calls the xBestIndex method when it is compiling a query
that involves a virtual table. In other words, SQLite calls this method 
when it is running <a href="c3ref/prepare.html">sqlite3_prepare()</a> or the equivalent. 
By calling this method, the 
SQLite core is saying to the virtual table that it needs to access 
some subset of the rows in the virtual table and it wants to know the
most efficient way to do that access. The xBestIndex method replies 
with information that the SQLite core can then use to conduct an 
efficient search of the virtual table.

give the best performance.

</p><p>Before calling this method, the SQLite core initializes an instance 
of the <a href="c3ref/index_info.html">sqlite3_index_info</a> structure with information about the
query that it is currently trying to process. This information 
derives mainly from the WHERE clause and ORDER BY or GROUP BY clauses 
of the query, but also from any ON or USING clauses if the query is a 
join. The information that the SQLite core provides to the xBestIndex 
method is held in the part of the structure that is marked as "Inputs". 
The "Outputs" section is initialized to zero.

<a href="c3ref/index_info.html">sqlite3_index_info</a> structure, it should make a copy.  Care must be
take to store the copy in a place where it will be deallocated, such

<h3 id="section_2_3_1">2.3.1. Inputs</h3>
</p><h3 id="inputs"><span>2.3.1. </span>Inputs</h3>

<p>The main thing that the SQLite core is trying to communicate to 
the virtual table is the constraints that are available to limit 
the number of rows that need to be searched. The aConstraint[] array 
contains one entry for each constraint. There will be exactly 
nConstraint entries in that array.

<p>Each constraint will correspond to a term in the WHERE clause
</p><p>Each constraint will correspond to a term in the WHERE clause
or in a USING or ON clause that is of the form

<blockquote>
</p><blockquote>
     column  OP  EXPR
</blockquote>

<p>Where "column" is a column in the virtual table, OP is an operator 
like "=" or "&lt;", and EXPR is an arbitrary expression. So, for example,
if the WHERE clause contained a term like this:

<blockquote><pre>
     a = 5
</pre></blockquote>
</p><div class="codeblock"><pre>a = 5
</pre></div>

<p>Then one of the constraints would be on the "a" column with 
operator "=" and an expression of "5". Constraints need not have a
literal representation of the WHERE clause. The query optimizer might
make transformations to the 
WHERE clause in order to extract as many constraints 
as it can. So, for example, if the WHERE clause contained something 
like this:

<blockquote><pre>
     x BETWEEN 10 AND 100 AND 999&gt;y
</pre></blockquote>
</p><div class="codeblock"><pre>x BETWEEN 10 AND 100 AND 999&gt;y
</pre></div>

<p>The query optimizer might translate this into three separate constraints:

<blockquote><pre>
     x &gt;= 10
     x &lt;= 100
     y &lt; 999
</pre></blockquote>
</p><div class="codeblock"><pre>x &gt;= 10
x &lt;= 100
y &lt; 999
</pre></div>

<p>For each constraint, the aConstraint[].iColumn field indicates which 
column appears on the left-hand side of the constraint.
The first column of the virtual table is column 0. 
The rowid of the virtual table is column -1. 
The aConstraint[].op field indicates which operator is used. 
The SQLITE_INDEX_CONSTRAINT_* constants map integer constants 
into operator values.
Columns occur in the order they were defined by the call to
<a href="c3ref/declare_vtab.html">sqlite3_declare_vtab()</a> in the <a href="vtab.html#xcreate">xCreate</a> or <a href="vtab.html#xconnect">xConnect</a> method.
Hidden columns are counted when determining the column index.

<p>The aConstraint[] array contains information about all constraints 
</p><p>The aConstraint[] array contains information about all constraints 
that apply to the virtual table. But some of the constraints might
not be usable because of the way tables are ordered in a join. 
The xBestIndex method must therefore only consider constraints 
that have an aConstraint[].usable flag which is true.

<p>In addition to WHERE clause constraints, the SQLite core also 
</p><p>In addition to WHERE clause constraints, the SQLite core also 
tells the xBestIndex method about the ORDER BY clause. 
(In an aggregate query, the SQLite core might put in GROUP BY clause 
information in place of the ORDER BY clause information, but this fact
should not make any difference to the xBestIndex method.) 
If all terms of the ORDER BY clause are columns in the virtual table, 
then nOrderBy will be the number of terms in the ORDER BY clause 
and the aOrderBy[] array will identify the column for each term 
in the order by clause and whether or not that column is ASC or DESC.

<a name="colUsed"></a>

<p>In SQLite version 3.10.0 and later, the colUsed field is available
</p><p>In SQLite version 3.10.0 and later, the colUsed field is available
to indicate which fields of the virtual table are actually used by the
statement being prepared.  If the lowest bit of colUsed is set, that
means that the first column is used.  The second lowest bit corresponds
to the second column.  And so forth.  If the most significant bit of
colUsed is set, that means that one or more columns other than the 
first 63 columns are used.  If column usage information is needed by the
<a href="vtab.html#xfilter">xFilter</a> method, then the required bits must be encoded into either
the idxNum or idxStr output fields.

<h3 id="section_2_3_2">2.3.2. Outputs</h3>
</p><h3 id="outputs"><span>2.3.2. </span>Outputs</h3>

<p>Given all of the information above, the job of the xBestIndex 
method it to figure out the best way to search the virtual table.

<p>The xBestIndex method fills the idxNum and idxStr fields with 
</p><p>The xBestIndex method fills the idxNum and idxStr fields with 
information that communicates an indexing strategy to the <a href="vtab.html#xfilter">xFilter</a> 
method. The information in idxNum and idxStr is arbitrary as far 
as the SQLite core is concerned. The SQLite core just copies the 
information through to the <a href="vtab.html#xfilter">xFilter</a> method. Any desired meaning can 
be assigned to idxNum and idxStr as long as xBestIndex and xFilter 
agree on what that meaning is.

<p>The idxStr value may be a string obtained from an SQLite
</p><p>The idxStr value may be a string obtained from an SQLite
memory allocation function such as <a href="c3ref/mprintf.html">sqlite3_mprintf()</a>. 
If this is the case, then the needToFreeIdxStr flag must be set to 
true so that the SQLite core will know to call <a href="c3ref/free.html">sqlite3_free()</a> on 
that string when it has finished with it, and thus avoid a memory leak.

<p>If the virtual table will output rows in the order specified by 
</p><p>If the virtual table will output rows in the order specified by 
the ORDER BY clause, then the orderByConsumed flag may be set to 
true. If the output is not automatically in the correct order 
then orderByConsumed must be left in its default false setting. 
This will indicate to the SQLite core that it will need to do a 
separate sorting pass over the data after it comes out of the virtual table.

<p>The estimatedCost field should be set to the estimated number
</p><p>The estimatedCost field should be set to the estimated number
of disk access operations required to execute this query against 
the virtual table. The SQLite core will often call xBestIndex 
multiple times with different constraints, obtain multiple cost
estimates, then choose the query plan that gives the lowest estimate.

<p>If the current version of SQLite is 3.8.2 or greater, the estimatedRows
</p><p>If the current version of SQLite is 3.8.2 or greater, the estimatedRows
field may be set to an estimate of the number of rows returned by the
proposed query plan. If this value is not explicitly set, the default 
estimate of 25 rows is used.

<p>If the current version of SQLite is 3.9.0 or greater, the idxFlags field
</p><p>If the current version of SQLite is 3.9.0 or greater, the idxFlags field
may be set to SQLITE_INDEX_SCAN_UNIQUE to indicate that the virtual table
will return only zero or one rows given the input constraints.  Additional
bits of the idxFlags field might be understood in later versions of SQLite.

<p>The aConstraintUsage[] array contains one element for each of 
</p><p>The aConstraintUsage[] array contains one element for each of 
the nConstraint constraints in the inputs section of the 
<a href="c3ref/index_info.html">sqlite3_index_info</a> structure.

core how it is using the constraints.

<p>The xBestIndex method may set aConstraintUsage[].argvIndex 
</p><p>The xBestIndex method may set aConstraintUsage[].argvIndex 
entries to values greater than zero. 
Exactly one entry should be set to 1, another to 2, another to 3, 
and so forth up to as many or as few as the xBestIndex method wants. 
The EXPR of the corresponding constraints will then be passed 
in as the argv[] parameters to xFilter.

<p>For example, if the aConstraint[3].argvIndex is set to 1, then 
</p><p>For example, if the aConstraint[3].argvIndex is set to 1, then

each row of the virtual table that it receives. If such a check 
is redundant, the xBestFilter method can suppress that double-check by
