<h2>1.3 Options To Control Operating Characteristics</h2>
192
<a name="have_isnan"></a>
210
<a name="case_sensitive_like"></a>
211
<p><b>SQLITE_CASE_SENSITIVE_LIKE</b></p><blockquote><p>
212
If this option is present, then the built-in <a href="lang_expr.html#like">LIKE</a> operator will be
213
case sensitive. This same effect can be achieved at run-time using
214
the <a href="pragma.html#pragma_case_sensitive_like">case_sensitive_like pragma</a>.
215
</p></blockquote><a name="have_isnan"></a>
193
216
<p><b>SQLITE_HAVE_ISNAN</b></p><blockquote><p>
194
217
If this option is present, then SQLite will use the isnan() function from
195
218
the system math library. Without this option (the default behavior)
406
429
<p><b>SQLITE_ENABLE_RTREE</b></p><blockquote><p>
407
430
This option causes SQLite to include support for the
408
431
<a href="rtree.html">R*Tree index extension</a>.
432
</p></blockquote><a name="enable_stat2"></a>
433
<p><b>SQLITE_ENABLE_STAT2</b></p><blockquote><p>
434
This option adds additional logic to the <a href="lang_analyze.html">ANALYZE</a> command and to
435
the <a href="optoverview.html">query planner</a> that can help SQLite to chose a better query plan
436
under certain situations. The <a href="lang_analyze.html">ANALYZE</a> command is enhanced to collect
437
a 10-sample histogram of the data in each index and store that histogram
438
in the <b>sqlite_stat2</b> table. The query planner will then use the
439
histogram data to help it estimate how many rows will be selected by a
440
<a href="optoverview.html#rangequery">range constraint</a> in a WHERE clause.
409
441
</p></blockquote><a name="enable_update_delete_limit"></a>
410
442
<p><b>SQLITE_ENABLE_UPDATE_DELETE_LIMIT</b></p><blockquote><p>
411
443
This option enables an optional ORDER BY and LIMIT clause on
499
531
header file "sqlite3.h") can then be moved to a non-unix platform
500
532
for final compilation using a native compiler.</p>
