This is the Reference Manual for the MySQL Database System, version
5.4, through release 5.4.3. For license
information, see the legal
notice. Differences between minor versions of MySQL
5.4 are noted in the present text with reference to
release numbers (5.4.x).
This manual is not intended for use with older versions of the MySQL software due to the many functional and other differences between MySQL 5.4 and previous versions. If you are using an earlier release of the MySQL software, please refer to the appropriate manual. For example, MySQL 5.1 Reference Manual, covers the 5.1 series of MySQL software releases.
If you are using MySQL 5.5, please refer to the MySQL 5.5 Reference Manual.
The following is a list of the libraries we have included with the MySQL Server source and components used to test MySQL. We are thankful to all individuals that have created these. Some of the components require that their licensing terms be included in the documentation of products that include them. Cross references to these licensing terms are given with the applicable items in the list.

REGEXP operations. License:

N O T I C E
Copyright Abandoned, 1987, Fred Fish
This previously copyrighted work has been placed into the public
domain by the author and may be freely used for any purpose,
private or commercial.
Because of the number of inquiries I was receiving about the use
of this product in commercially developed works I have decided to
simply make it public domain to further its unrestricted use. I
specifically would be most happy to see this material become a
part of the standard Unix distributions by AT&T and the Berkeley
Computer Science Research Group, and a standard part of the GNU
system from the Free Software Foundation.
I would appreciate it, as a courtesy, if this notice is left in
all copies and derivative works. Thank you.
The author makes no warranty of any kind with respect to this
product and explicitly disclaims any implied warranties of mer-
chantability or fitness for any particular purpose.

The following software may be included in this product:
md5 (Message-Digest Algorithm 5) This code implements the MD5 message-digest algorithm. The algorithm is due to Ron Rivest. This code was written by Colin Plumb in 1993, no copyright is claimed. This code is in the public domain; do with it what you wish. Equivalent code is available from RSA Data Security, Inc. This code has been tested against that, and is equivalent, except that you don't need to include two pages of legalese with every copy. The code has been modified by Mikael Ronstroem to handle calculating a hash value of a key that is always a multiple of 4 bytes long. Word 0 of the calculated 4-word hash value is returned as the hash value.
