[edit] Synopsis

MySQL is a free, widely used SQL engine. It can be used as a fast database as well as a rock-solid SGDB using a modular engine architecture.

A printable version of MySQL is available. (edit it)

The purpose of this wikibook is to provide a practical knowledge on using the database from two points of view:

  • application developer: learn about SQL basics, phpMyAdmin, query optimization
  • system administrator: learn about installation, security, maintenance, failover, high availability

Best of all, this book is freely available for everybody to use and share, under the GNU Free Documentation License.

    • Savane's migration scripts, in the update/version directory
  • Charsets: what are Latin1 and UTF-8? How to cleanly convert a database from Latin1 to UTF-8 (not just mysqldump|iconv, also ALTER TABLE table MODIFY col VARCHAR(100) CHARACTER SET utf8 + SET NAMES 'utf8' in PHP), phpMyAdmin bugs (need to add SET NAMES utf8 in some circumstances)

[edit] Suggestions

Case study: I was suggested to use SPIP (a system to manage articles and news) for a sample study. Mediawiki might be interesting as well :)


Add a list of CLIENTS to use with MYSQL, I dont know of any good ones, MYSQL GUI ones are ok, but I need some others
