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 terabytes
|
|
(2<sup><small>41</small></sup> bytes) in size.</li>
|
|
<li>Sizes of strings and BLOBs limited only by available memory.</li>
|
|
<li>Small code footprint: less than 250KiB 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 95% test coverage.</li>
|
|
<li>Self-contained: no external dependencies.</li>
|
|
<li>Sources are in the <a href="copyright.html">public domain</a>.
|
|
Use for any purpose.</li>
|
|
</ul>

<p>
|
|
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.

newsitme {2006-Apr-5} {Version 3.3.5} {
|
|
This release fixes many minor bugs and documentation typos and
|
|
provides some minor new features and performance enhancements.
|
|
Upgrade only if you are having problems or need one of the new features.
|
|
}
|
|
|
|
newsitem {2006-Feb-11} {Version 3.3.4} {
|
|
This release fixes several bugs, including a
|
|
a blunder that might cause a deadlock on multithreaded systems.
|
|
Anyone using SQLite in a multithreaded environment should probably upgrade.
|
|
}
|
|
|
|
newsitem {2006-Jan-31} {Version 3.3.3 stable} {
|
|
There have been no major problems discovered in version 3.3.2, so
|
|
we hereby declare the new APIs and language features to be stable
|
|
and supported.
|
|
}
|
|
|
|
newsitem {2006-Jan-24} {Version 3.3.2 beta} {
|
|
More bug fixes and performance improvements as we move closer to
|
|
a production-ready version 3.3.x.
|
|
}
|
|
|
|
newsitem {2006-Jan-16} {Version 3.3.1 alpha} {
|
|
Many bugs found in last week's alpha release have now been fixed and
|
|
the library is running much faster again.
|
|
|
|
Database connections can now be moved between threads as long as the
|
|
connection holds no locks at the time it is moved. Thus the common
|
|
paradigm of maintaining a pool of database connections and handing
|
|
them off to transient worker threads is now supported.
|
|
Please help test this new feature.
|
|
See <a href="http://www.sqlite.org/cvstrac/wiki?p=MultiThreading">
|
|
the MultiThreading wiki page</a> for additional
|
|
information.
|
|
}
|
|
|
|
newsitem {2006-Jan-10} {Version 3.3.0 alpha} {
|
|
Version 3.3.0 adds support for CHECK constraints, DESC indices,
|
|
separate REAL and INTEGER column affinities, a new OS interface layer
|
|
design, and many other changes. The code passed a regression
|
|
test but should still be considered alpha. Please report any
|
|
problems.
|
|
|
|
The file format for version 3.3.0 has changed slightly in order provide
|
|
a more efficient encoding of binary values. SQLite 3.3.0 will read and
|
|
write legacy databases created with any prior version of SQLite 3. But
|
|
databases created by version 3.3.0 will not be readable or writable
|
|
by earlier versions of the SQLite. The older file format can be
|
|
specified at compile-time for those rare cases where it is needed.
|
|
}
|
|
|
|
newsitem {2005-Dec-19} {Versions 3.2.8 and 2.8.17} {
|
|
These versions contain one-line changes to 3.2.7 and 2.8.16 to fix a bug
|
|
that has been present since March of 2002 and version 2.4.0.
|
|
That bug might possibly cause database corruption if a large INSERT or
|
|
UPDATE statement within a multi-statement transaction fails due to a
|
|
uniqueness constraint but the containing transaction commits.
