Um... mySQL is a server, a relational databaes management server to be exact. You install the mySQL server, make sure the server daemon is running, then access your tables databases and tables using contructs and functions from your language of choice. Both source and binary downloads for *Nix and Win32 are available from http://www.mysql.com/downloads/. HTH,
