<h2>SQLite Release 3.8.0.2 On 2013-09-03</h2><p><ol class='lessindent'>
|
|
<li>Add support for <a href="../partialindex.html">partial indexes</a></li>
|
|
<li>Cut-over to the <a href="../queryplanner-ng.html">next generation query planner</a> for faster and better query plans.
|
|
<li>The <a href="../eqp.html">EXPLAIN QUERY PLAN</a> output no longer shows an estimate of the number of
|
|
rows generated by each loop in a join.
|
|
<li>Added the <a href="../fts3.html#fts4notindexed">FTS4 notindexed option</a>, allowing non-indexed columns in an FTS4 table.
|
|
<li>Added the <a href="../c3ref/c_stmtstatus_counter.html#sqlitestmtstatusvmstep">SQLITE_STMTSTATUS_VM_STEP</a> option to <a href="../c3ref/stmt_status.html">sqlite3_stmt_status()</a>.
|
|
<li>Added the <a href="../pragma.html#pragma_cache_spill">cache_spill pragma</a>.
|
|
<li>Added the <a href="../pragma.html#pragma_query_only">query_only pragma</a>.
|
|
<li>Added the <a href="../pragma.html#pragma_defer_foreign_keys">defer_foreign_keys pragma</a> and the
|
|
<a href="../c3ref/db_status.html">sqlite3_db_status</a>(db, <a href="../c3ref/c_dbstatus_options.html#sqlitedbstatusdeferredfks">SQLITE_DBSTATUS_DEFERRED_FKS</a>,...) C-language interface.
|
|
<li>Added the "percentile()" function as a <a href="../loadext.html">loadable extension</a> in the ext/misc
|
|
subdirectory of the source tree.
|
|
<li>Added the <a href="../compile.html#allow_uri_authority">SQLITE_ALLOW_URI_AUTHORITY</a> compile-time option.
|
|
<li>Add the <a href="../c3ref/cancel_auto_extension.html">sqlite3_cancel_auto_extension(X)</a> interface.
|
|
<li>A running SELECT statement that lacks a FROM clause (or any other statement that
|
|
never reads or writes from any database file) will not prevent a read
|
|
transaction from closing.
|
|
<li>Add the <a href="../compile.html#default_automatic_index">SQLITE_DEFAULT_AUTOMATIC_INDEX</a> compile-time option. Setting this option
|
|
to 0 disables automatic indices by default.
|
|
<li>Issue an <a href="../rescode.html#warning_autoindex">SQLITE_WARNING_AUTOINDEX</a> warning on the <a href="../c3ref/c_config_covering_index_scan.html#sqliteconfiglog">SQLITE_CONFIG_LOG</a> whenever
|
|
the query planner uses an automatic index.
|
|
<li>Added the <a href="../compile.html#fts3_max_expr_depth">SQLITE_FTS3_MAX_EXPR_DEPTH</a> compile-time option.
|
|
<li>Added an optional 5th parameter defining the collating sequence to the
|
|
next_char() extension SQL function.
|
|
<li>The <a href="../rescode.html#busy_snapshot">SQLITE_BUSY_SNAPSHOT</a> extended error code is returned in WAL mode when
|
|
a read transaction cannot be upgraded to a write transaction because the read is
|
|
on an older snapshot.
|
|
<li>Enhancements to the sqlite3_analyzer utility program to provide size
|
|
information separately for each individual index of a table, in addition to
|
|
the aggregate size.
|
|
<li>Allow read transactions to be freely opened and closed by SQL statements run
|
|
from within the implementation of <a href="../appfunc.html">application-defined SQL functions</a> if the
|
|
function is called by a SELECT statement that does not access any database table.
|
|
<li>Disable the use of posix_fallocate() on all (unix) systems unless the
|
|
HAVE_POSIX_FALLOCATE compile-time option is used.
|
|
<li>Update the ".import" command in the <a href="../cli.html">command-line shell</a> to support multi-line
|
|
fields and correct RFC-4180 quoting and to issue warning and/or error messages
|
|
if the input text is not strictly RFC-4180 compliant.
|
|
<li>Bug fix: In the <a href="../fts3.html#unicode61">unicode61</a> tokenizer of <a href="../fts3.html#fts4">FTS4</a>, treat all private code points
|
|
as identifier symbols.
|
|
<li>Bug fix: Bare identifiers in ORDER BY clauses bind more tightly to output column
|
|
names, but identifiers in expressions bind more tightly to input column names.
|
|
Identifiers in GROUP BY clauses always prefer output column names, however.
|
|
<li>Bug fixes: Multiple problems in the legacy query optimizer were fixed by the
|
|
move to <a href="../queryplanner-ng.html">NGQP</a>.
|
|
|
|
</ol></p><p><ol class='lessindent'>
|
|
<li>Fix an off-by-one error that caused quoted empty string at the end of a
|
|
CRNL-terminated line of CSV input to be misread by the command-line shell.
|
|
<li>Fix a query planner bug involving a LEFT JOIN with a BETWEEN or LIKE/GLOB
|
|
constraint and then another INNER JOIN to the right that involves an OR constraint.
|
|
<li>Fix a query planner bug that could result in a segfault when querying tables
|
|
with a UNIQUE or PRIMARY KEY constraint with more than four columns.
|
|
|
|
</ol></p><p><ol class='lessindent'>
|
|
<li>Fix a bug in the optimization that attempts to omit unused LEFT JOINs
