SQLite 3.3.6 or newer strongly recommended
------------------------------------------
Versions of SQLite 3.3.5 and older contains the following bugs:
* A bug when `handling`_ ``ORDER BY`` parameters. This can cause problems when
you use the ``select`` parameter for the ``extra()`` QuerySet method. The bug
can be identified by the error message ``OperationalError: ORDER BY terms
must not be non-integer constants``.
* A bug when handling `aggregation`_ together with DateFields and
DecimalFields.

.. _aggregation: https://code.djangoproject.com/ticket/10031
SQLite 3.3.6 was released in April 2006, so most current binary distributions
for different platforms include newer version of SQLite usable from Python
through either the ``pysqlite2`` or the ``sqlite3`` modules.
Version 3.5.9
-------------
The Ubuntu "Intrepid Ibex" (8.10) SQLite 3.5.9-3 package contains a bug that
causes problems with the evaluation of query expressions. If you are using
Ubuntu "Intrepid Ibex", you will need to update the package to version
3.5.9-3ubuntu1 or newer (recommended) or find an alternate source for SQLite
packages, or install SQLite from source.
At one time, Debian Lenny shipped with the same malfunctioning SQLite 3.5.9-3
package. However the Debian project has subsequently issued updated versions
of the SQLite package that correct these bugs. If you find you are getting
unexpected results under Debian, ensure you have updated your SQLite package
to 3.5.9-5 or later.
The problem does not appear to exist with other versions of SQLite packaged
with other operating systems.
Version 3.6.2
--------------
SQLite version 3.6.2 (released August 30, 2008) introduced a bug into ``SELECT
DISTINCT`` handling that is triggered by, among other things, Django's
``DateQuerySet`` (returned by the ``dates()`` method on a queryset).
You should avoid using this version of SQLite with Django. Either upgrade to
3.6.3 (released September 22, 2008) or later, or downgrade to an earlier
version of SQLite.
