Toggles autocommit mode on or off for the current database connection. Autocommit mode will be set if mode=1 or unset if mode=0. Returns zero on success, or nonzero if an error occurred.
Parameters
mode only affects operations on transactional table types. To determine the current state of autocommit mode use the SQL command SELECT @@autocommit. Be aware: the function will not work if autocommit mode is switched on.
