<h2>SQLite Release 3.14 On 2016-08-08</h2><p><ol class='lessindent'>
<div style="width:280px;float:right;padding:10px;margin:0px 10px;">
<img src='../images/sqlitepie.jpg' width=280 height=250></img><br>
<center>Celebrating the SQLite "<big>&pi;</big> release"
with a home-baked pie.</center>
</div>
<li>Added support for <a href="../vtab.html#worid">WITHOUT ROWID virtual tables</a>.
<li>Improved the query planner so that the <a href="../optoverview.html#or_opt">OR optimization</a> can
    be used on <a href="../vtab.html">virtual tables</a> even if one or more of the disjuncts
    use the <a href="../lang_expr.html#like">LIKE</a>, <a href="../lang_expr.html#glob">GLOB</a>, <a href="../lang_expr.html#regexp">REGEXP</a>, <a href="../lang_expr.html#match">MATCH</a> operators.
<li>Added the <a href="../csv.html">CSV virtual table</a> for reading
    <a href="https://www.ietf.org/rfc/rfc4180.txt">RFC 4180</a> formatted comma-separated
    value files.
<li>Added the <a href="../carray.html">carray() table-valued function</a> extension.
<li>Enabled <a href="../loadext.html#persist">persistent loadable extensions</a> using the new
    <a href="../rescode.html#ok_load_permanently">SQLITE_OK_LOAD_PERMANENTLY</a> return code from the extension
    entry point.
<li>Added the <a href="../c3ref/c_dbstatus_options.html#sqlitedbstatuscacheusedshared">SQLITE_DBSTATUS_CACHE_USED_SHARED</a> option to <a href="../c3ref/db_status.html">sqlite3_db_status()</a>.
<li>Add the
    <a href="https://www.sqlite.org/src/artifact?ci=trunk&filename=ext/misc/vfsstat.c">vfsstat.c</a>
    loadable extension - a VFS shim that measures I/O
    together with an <a href="../vtab.html#epovtab">eponymous virtual table</a> that provides access to the measurements.
<li>Improved algorithm for running queries with both an ORDER BY and a LIMIT where
    only the inner-most loop naturally generates rows in the correct order.
<li>Enhancements to <a href="../lemon.html">Lemon parser generator</a>, so that it generates a
    faster parser.
<li>The <a href="../pragma.html#pragma_compile_options">PRAGMA compile_options</a> command now attempts to show the version number
    of the compiler that generated the library.
<li>Enhance <a href="../pragma.html#pragma_table_info">PRAGMA table_info</a> so that it provides information about
    <a href="../vtab.html#epovtab">eponymous virtual tables</a>.
<li>Added the "win32-none" VFS, analogous to the "unix-none" VFS, that works like
    the default "win32" VFS except that it ignores all file locks.
<li>The query planner uses a full scan of a <a href="../partialindex.html">partial index</a> instead of a
    full scan of the main table, in cases where that makes sense.
<li>Allow <a href="../vtab.html#tabfunc2">table-valued functions</a> to appear on the right-hand side of an <a href="../lang_expr.html#in_op">IN operator</a>.
<li>Created the <a href="../dbhash.html">dbhash.exe</a> command-line utility.
<li>Added two new C-language interfaces: <a href="../c3ref/expanded_sql.html">sqlite3_expanded_sql()</a> and
    <a href="../c3ref/trace_v2.html">sqlite3_trace_v2()</a>.  These new interfaces subsume the functions of
    <a href="../c3ref/profile.html">sqlite3_trace()</a> and <a href="../c3ref/profile.html">sqlite3_profile()</a> which are now deprecated.
<li>Added the <a href="../json1.html#jquote">json_quote()</a> SQL function to <a href="../json1.html">the json1 extension</a>.
<li>Disable the <a href="../c3ref/set_authorizer.html">authorizer callback</a> while reparsing the schema.
<li>Added the <a href="../compile.html#enable_unknown_sql_function">SQLITE_ENABLE_UNKNOWN_SQL_FUNCTION</a> compile-time option and turned that
    option on by default when building the <a href="../cli.html">command-line shell</a>.
<p><b>Bug Fixes:</b>
<li>Fix the <a href="../lang_altertable.html">ALTER TABLE</a> command so that it does not corrupt <a href="../lang_createindex.html#descidx">descending indexes</a>
    when adding a column to a <a href="../pragma.html#pragma_legacy_file_format">legacy file format</a> database.  Ticket
    <a href="https://www.sqlite.org/src/info/f68bf68513a1c15f">f68bf68513a1c15f</a>
<li>Fix a NULL-pointer dereference/crash that could occurs when a transitive WHERE
    clause references a non-existent collating sequence.  Ticket
    <a href="https://www.sqlite.org/src/info/e8d439c77685eca6">e8d439c77685eca6</a>.
<li>Improved the cost estimation for an index scan which includes a WHERE clause
    that can be partially or fully evaluated using columns in the index and without
    having to do a table lookup.  This fixes a performance regression that occurred
    for some obscure queries following the ORDER BY LIMIT optimization introduced
    in <a href="../releaselog/3_12_0.html">version 3.12.0</a>.
