odbc_autocommit — Toggle autocommit behaviour
Toggles autocommit behaviour.
By default, auto-commit is on for a connection. Disabling auto-commit is equivalent with starting a transaction.
ODBC 连接标识符，详见 odbc_connect()。
If OnOff is TRUE, auto-commit is enabled, if it is FALSE auto-commit is disabled.
Without the OnOff parameter, this function returns auto-commit status for connection_id. Non-zero is returned if auto-commit is on, 0 if it is off, or FALSE if an error occurs.
If OnOff is set, this function returns TRUE on success and FALSE on failure.
