<h2>SQLite Release 3.8.6 On 2014-08-15</h2><p><ol class='lessindent'>
|
|
<li>Added support for <a href="../lang_expr.html#hexint">hexadecimal integer literals</a> in the SQL parser.
|
|
(Ex: 0x123abc)
|
|
<li>Enhanced the <a href="../pragma.html#pragma_integrity_check">PRAGMA integrity_check</a> command to detect <a href="../lang_createtable.html#uniqueconst">UNIQUE</a> and
|
|
<a href="../lang_createtable.html#notnullconst">NOT NULL</a> constraint violations.
|
|
<li>Increase the maximum value of <a href="../limits.html#max_attached">SQLITE_MAX_ATTACHED</a> from 62 to 125.
|
|
<li>Increase the timeout in <a href="../wal.html">WAL mode</a> before issuing an <a href="../rescode.html#protocol">SQLITE_PROTOCOL</a>
|
|
error from 1 second to 10 seconds.
|
|
<li>Added the <a href="../lang_corefunc.html#likely">likely(X)</a> SQL function.
|
|
<li>The <a href="../fts3.html#unicode61">unicode61</a> tokenizer is now included in <a href="../fts3.html#fts4">FTS4</a> by default.
|
|
<li>Trigger automatic reprepares on all prepared statements when <a href="../lang_analyze.html">ANALYZE</a> is
|
|
run.
|
|
<li>Added a new
|
|
<a href="../loadext.html">loadable extension</a> source code file to the source tree:
|
|
<a href="http://www.sqlite.org/src/finfo?name=ext/misc/fileio.c">fileio.c</a>
|
|
<li>Add extension functions <a href="../cli.html#fileio">readfile(X) and writefile(X,Y)</a>
|
|
(using code copy/pasted from fileio.c in the previous bullet) to the
|
|
<a href="../cli.html">command-line shell</a>.
|
|
<li>Added the <a href="../cli.html#fullschema">.fullschema</a> dot-command to the <a href="../cli.html">command-line shell</a>.
|
|
<p><b>Performance Enhancements:</b>
|
|
<li>Deactivate the <a href="../lang_select.html#distinct">DISTINCT</a> keyword on subqueries on the
|
|
right-hand side of the <a href="../lang_expr.html#in_op">IN operator</a>.
|
|
<li>Add the capability of evaluating an <a href="../lang_expr.html#in_op">IN operator</a> as a sequence
|
|
of comparisons as an alternative to using a table lookup. Use the sequence
|
|
of comparisons implementation in circumstances where it is likely to be
|
|
faster, such as when the right-hand side of the IN operator
|
|
is small and/or changes frequently.
|
|
<li>The query planner now uses <a href="../fileformat2.html#stat4tab">sqlite_stat4</a> information (created by <a href="../lang_analyze.html">ANALYZE</a>)
|
|
to help determine if the <a href="../optoverview.html#skipscan">skip-scan optimization</a> is appropriate.
|
|
<li>Ensure that the query planner never tries to use a self-made transient
|
|
index in place of a schema-defined index.
|
|
<li>Other minor tweaks to improve the quality of <a href="../opcode.html">VDBE</a> code.
|
|
<p><b>Bug Fixes:</b>
|
|
<li>Fix a bug in <a href="../lang_createindex.html">CREATE UNIQUE INDEX</a>, introduced when <a href="../withoutrowid.html">WITHOUT ROWID</a>
|
|
support added in version 3.8.2, that allows a non-unique NOT NULL column to be
|
|
given a UNIQUE index.
|
|
Ticket <a href="http://www.sqlite.org/src/info/9a6daf340df99ba93c">9a6daf340df99ba93c</a>
|
|
<li>Fix a bug in <a href="../rtree.html">R-Tree extension</a>, introduced in the previous release,
|
|
that can cause an
|
|
incorrect results for queries that use the rowid of the R-Tree on the
|
|
left-hand side of an <a href="../lang_expr.html#in_op">IN operator</a>.
|
|
Ticket <a href="http://www.sqlite.org/src/info/d2889096e7bdeac6">d2889096e7bdeac6</a>.
|
|
<li>Fix the <a href="../c3ref/stmt_busy.html">sqlite3_stmt_busy()</a> interface so that it gives the correct answer
|
|
for <a href="../lang_transaction.html">ROLLBACK</a> statements that have been stepped but never reset.
|
|
<li>Fix a bug in that would cause a null pointer to be dereferenced
|
|
if a column with a DEFAULT that is an aggregate function tried to usee its
|
|
DEFAULT.
|
|
Ticket <a href="http://www.sqlite.org/src/info/3a88d85f36704eebe1">3a88d85f36704eebe1</a>
|
|
<li>CSV output from the <a href="../cli.html">command-line shell</a> now always uses CRNL for the
|
|
row separator and avoids inserting CR in front of NLs contained in
|
|
data.
|
|
<li>Fix a <a href="../datatype3.html#affinity">column affinity</a> problem with the <a href="../lang_expr.html#in_op">IN operator</a>.
|
|
Ticket <a href="http://www.sqlite.org/src/info/9a8b09f8e6">9a8b09f8e6</a>.
|
|
<li>Fix the <a href="../lang_analyze.html">ANALYZE</a> command so that it adds correct samples for
|
|
<a href="../withoutrowid.html">WITHOUT ROWID</a> tables in the <a href="../fileformat2.html#stat4tab">sqlite_stat4</a> table.
|
|
Ticket <a href="http://www.sqlite.org/src/info/b2fa5424e6fcb15">b2fa5424e6fcb15</a>.
