SQLite is a small
|
|
C library that implements a self-contained, embeddable,
|
|
zero-configuration
|
|
SQL database engine.
|
|
Features include:
|
|
</p>
|
|
|
|
<p><ul>
|
|
<li>Transactions are atomic, consistent, isolated, and durable (ACID)
|
|
even after system crashes and power failures.
|
|
<li>Zero-configuration - no setup or administration needed.</li>
|
|
<li>Implements most of SQL92.
|
|
(<a href="omitted.html">Features not supported</a>)</li>
|
|
<li>A complete database is stored in a single disk file.</li>
|
|
<li>Database files can be freely shared between machines with
|
|
different byte orders.</li>
|
|
<li>Supports databases up to 2 tebibytes
|
|
(2<sup><small>41</small></sup> bytes) in size.</li>
|
|
<li>Strings and BLOBs up to 2 gibibytes (2<sup><small>31</small></sup> bytes)
|
|
in size.</li>
|
|
<li>Small code footprint:
|
|
<a href="http://www.sqlite.org/cvstrac/wiki?p=SizeOfSqlite">
|
|
less than 250KiB</a> fully configured or less
|
|
than 150KiB with optional features omitted.</li>
|
|
<li><a href="speed.html">Faster</a> than popular client/server database
|
|
engines for most common operations.</li>
|
|
<li>Simple, easy to use <a href="capi3.html">API</a>.</li>
|
|
<li><a href="tclsqlite.html">TCL bindings</a> included.
|
|
Bindings for many other languages
|
|
<a href="http://www.sqlite.org/cvstrac/wiki?p=SqliteWrappers">
|
|
available separately.</a></li>
|
|
<li>Well-commented source code with over 98% test coverage.</li>
|
|
<li>Available as a
|
|
<a href="http://www.sqlite.org/cvstrac/wiki?p=TheAmalgamation">
|
|
single ANSI-C source-code file</a> that you can easily drop into
|
|
another project.
|
|
<li>Self-contained: no external dependencies.</li>
|
|
<li>Sources are in the <a href="copyright.html">public domain</a>.
|
|
Use for any purpose.</li>

The SQLite distribution comes with a standalone command-line
|
|
access program (<a href="sqlite.html">sqlite</a>) that can
|
|
be used to administer an SQLite database and which serves as
|
|
an example of how to use the SQLite library.

newsitem {2007-Apr-25} {Version 3.3.17} {
|
|
This version fixes a bug in the forwards-compatibility logic of SQLite
|
|
that was causing a database to become unreadable when it should have
|
|
been read-only. Upgrade from 3.3.16 only if you plan to deploy into
|
|
a product that might need to be upgraded in the future. For day to day
|
|
use, it probably does not matter.
|
|
}
|
|
|
|
newsitem {2007-Apr-18} {Version 3.3.16} {
|
|
Performance improvements added in 3.3.14 but mistakenly turned off
|
|
in 3.3.15 have been reinstated. A bug has been fixed that prevented
|
|
VACUUM from running if a NULL value was in a UNIQUE column.
|
|
}
|
|
|
|
newsitem {2007-Apr-09} {Version 3.3.15} {
|
|
An annoying bug introduced in 3.3.14 has been fixed. There are
|
|
also many enhancements to the test suite.
|
|
}
|
|
|
|
newsitem {2007-Apr-02} {Version 3.3.14} {
|
|
This version focuses on performance improvements. If you recompile
|
|
<a href="http://www.sqlite.org/cvstrac/wiki?p=TheAmalgamation">
|
|
the amalgamation</a> using GCC option -O3 (the precompiled binaries
|
|
use -O2) you may see performance
|
|
improvements of 35% or more over version 3.3.13 depending on your
|
|
workload. This version also
|
|
adds support for <a href="pragma.html#pragma_locking_mode">
|
|
exclusive access mode</a>.
|
|
}
|
|
|
|
newsitem {2007-Feb-13} {Version 3.3.13} {
|
|
This version fixes a subtle bug in the ORDER BY optimizer that can
|
|
occur when using joins. There are also a few minor enhancements.
|
|
Upgrading is recommended.
|
|
}
|
|
|
|
newsitem {2007-Jan-27} {Version 3.3.12} {
|
|
The first published build of the previous version used the wrong
|
|
set of source files. Consequently, many people downloaded a build
|
|
that was labeled as "3.3.11" but was really 3.3.10. Version 3.3.12
|
|
is released to clear up the ambiguity. A couple more bugs have
|
|
also been fixed and <a href="pragma.html#pragma_integrity_check">
|
|
PRAGMA integrity_check</a> has been enhanced.
