<h2>SQLite Release 3.7.9 On 2011-11-01</h2><p><ol class='lessindent'>
|
|
<li>If a search token (on the right-hand side of the MATCH operator) in
|
|
<a href="../fts3.html#fts4">FTS4</a> begins with "^" then that token must be the first in its field
|
|
of the document. <b>** Potentially Incompatible Change **</b>
|
|
<li>Added options <a href="../c3ref/c_dbstatus_options.html#sqlitedbstatuscachehit">SQLITE_DBSTATUS_CACHE_HIT</a> and <a href="../c3ref/c_dbstatus_options.html#sqlitedbstatuscachemiss">SQLITE_DBSTATUS_CACHE_MISS</a>
|
|
to the <a href="../c3ref/db_status.html">sqlite3_db_status()</a> interface.
|
|
<li>Removed support for <a href="../compile.html#enable_stat2">SQLITE_ENABLE_STAT2</a>, replacing it with the much
|
|
more capable <a href="../compile.html#enable_stat3">SQLITE_ENABLE_STAT3</a> option.
|
|
<li>Enhancements to the sqlite3_analyzer utility program, including the
|
|
--pageinfo and --stats options and support for multiplexed databases.
|
|
<li>Enhance the <a href="../c3ref/data_count.html">sqlite3_data_count()</a> interface so that it can be used to
|
|
determine if SQLITE_DONE has been seen on the prepared statement.
|
|
<li>Added the <a href="../c3ref/c_fcntl_begin_atomic_write.html#sqlitefcntloverwrite">SQLITE_FCNTL_OVERWRITE</a> file-control by which the SQLite core
|
|
indicates to the VFS that the current transaction will overwrite the
|
|
entire database file.
|
|
<li>Increase the default <a href="../malloc.html#lookaside">lookaside memory allocator</a> allocation size from
|
|
100 to 128 bytes.
|
|
<li>Enhanced the query planner so that it can factor terms in and out of
|
|
OR expressions in the WHERE clause in an effort to find better indices.
|
|
<li>Added the <a href="../compile.html#direct_overflow_read">SQLITE_DIRECT_OVERFLOW_READ</a> compile-time option, causing
|
|
<a href="../fileformat2.html#ovflpgs">overflow pages</a> to be read directly from the database file,
|
|
bypassing the <a href="../c3ref/pcache_methods2.html">page cache</a>.
|
|
<li>Remove limits on the magnitude of precision and width value in the
|
|
format specifiers of the <a href="../c3ref/mprintf.html">sqlite3_mprintf()</a> family of string rendering
|
|
routines.
|
|
<li>Fix a bug that prevent <a href="../lang_altertable.html">ALTER TABLE ... RENAME</a> from working
|
|
on some virtual tables in a database with a UTF16 encoding.
|
|
<li>Fix a bug in ASCII-to-float conversion that causes slow performance and
|
|
incorrect results when converting numbers with ridiculously large exponents.
|
|
<li>Fix a bug that causes incorrect results in aggregate queries that use
|
|
multiple aggregate functions whose arguments contain complicated expressions
|
|
that differ only in the case of string literals contained within those
|
|
expressions.
|
|
<li>Fix a bug that prevented the <a href="../pragma.html#pragma_page_count">page_count</a> and <a href="../pragma.html#pragma_quick_check">quick_check</a> pragmas from
|
|
working correctly if their names were capitalized.
|
|
<li>Fix a bug that caused <a href="../lang_vacuum.html">VACUUM</a> to fail if the <a href="../pragma.html#pragma_count_changes">count_changes pragma</a> was
|
|
engaged.
|
|
<li>Fix a bug in <a href="../vtab.html">virtual table</a> implementation that causes a crash if
|
|
an <a href="../fts3.html#fts4">FTS4</a> table is <a href="../lang_droptable.html">dropped</a> inside a transaction and
|
|
a <a href="../lang_savepoint.html">SAVEPOINT</a> occurs afterwards.
|
|

|
