The MySQL® software delivers a very fast, multi-threaded, multi-user, and robust SQL (Structured Query Language) database server.

The MySQL software is Dual Licensed. Users can choose to use the MySQL software as an Open Source product under the terms of the GNU General Public License (http://www.fsf.org/licenses/) or can purchase a standard commercial license from MySQL AB.

This is the Reference Manual for the MySQL Database System,
version 5.0, through release 5.0.25. It is
not intended for use with older versions of the MySQL software due
to the many functional and other differences between MySQL
5.0 and previous versions.
If you are using a version 4.1 release of the MySQL
software, please refer to the
MySQL 3.23, 4.0, 4.1 Reference Manual, which covers the
3.23, 4.0, and 4.1 series of MySQL software releases. Differences
between minor versions of MySQL 5.0 are noted in the
present text with reference to release numbers
(5.0.x).
Because this manual serves as a reference, it does not provide general instruction on SQL or relational database concepts. It also does not teach you how to use your operating system or command-line interpreter.
The MySQL Database Software is under constant development, and the Reference Manual is updated frequently as well. The most recent version of the manual is available online in searchable form at http://dev.mysql.com/doc/. Other formats also are available there, including HTML, PDF, and Windows CHM versions.
The Reference Manual source files are written in DocBook XML format. The HTML version and other formats are produced automatically, primarily using the DocBook XSL stylesheets. For information about DocBook, see http://docbook.org/
The DocBook XML sources of this manual are available from http://dev.mysql.com/tech-resources/sources.html. You can check out a copy of the documentation repository with this command:
