MySQL completion should be included in a distinct package (currently Sublime Text 2 include MySQL completion in PHP completion),
because some MySQL functions are already deprecated and will be removed in the future and
because MySQL has been extended with Mysqli, Mysqlnd, Mysqlnd_ms, Mysqlnd_qc, Mysqlnd_uh, Mysqlnd_mux and Mysqlnd_memcache.

MySQL Function completion should have the full syntax
mysql_connect(server,user,pwd,newlink,clientflag)
mysql_select_db(database,connection)

Mysqli Class completion
Mysqli_stmt Class completion
Mysqli_result Class completion
Mysqli_driver Class completion
Mysqli_warning Class completion

Mysqlnd completion
Mysqlnd_ms completion
Mysqlnd_qc completion
Mysqlnd_uh completion
Mysqlnd_mux completion
