<h2>SQLite Release 3.5.4 On 2007-12-14</h2><p><ol class='lessindent'>
|
|
<li>Fix a critical bug in UPDATE or DELETE that occurs when an
|
|
OR REPLACE clause or a trigger causes rows in the same table to
|
|
be deleted as side effects. (See ticket #2832.) The most likely
|
|
result of this bug is a segmentation fault, though database
|
|
corruption is a possibility.</li>
|
|
<li>Bring the processing of ORDER BY into compliance with the
|
|
SQL standard for case where a result alias and a table column name
|
|
are in conflict. Correct behavior is to prefer the result alias.
|
|
Older versions of SQLite incorrectly picked the table column.
|
|
(See ticket #2822.)</li>
|
|
<li>The <a href="../lang_vacuum.html">VACUUM</a> command preserves
|
|
the setting of the
|
|
<a href="../pragma.html#pragma_legacy_file_format">legacy_file_format pragma</a>.
|
|
(Ticket #2804.)</li>
|
|
<li>Productize and officially support the group_concat() SQL function.</li>
|
|
<li>Better optimization of some IN operator expressions.</li>
|
|
<li>Add the ability to change the
|
|
<a href="../pragma.html#pragma_auto_vacuum">auto_vacuum</a> status of a
|
|
database by setting the auto_vaccum pragma and VACUUMing the database.</li>
|
|
<li>Prefix search in FTS3 is much more efficient.</li>
|
|
<li>Relax the SQL statement length restriction in the CLI so that
|
|
the ".dump" output of databases with very large BLOBs and strings can
|
|
be played back to recreate the database.</li>
|
|
<li>Other small bug fixes and optimizations.</li>
