MySQL is the most popular SQL database in the open source community and is used almost universally by web sites running on open source systems. As powerful and flexible as it is lightweight and efficient, MySQL packs a large feature set into a very small and fast engine that now runs on more than 500,000 servers. This renowned online manual that has supported MySQL administrators and database developers for years is now available in paperback format.
