int odbc_autocommit(int connection_id, int [OnOff]);Without the OnOff parameter, this function returns auto-commit status for connection_id. True is returned if auto-commit is on, false if it is off or an error occurs.
If OnOff is true, auto-commit is enabled, if it is false auto-commit is disabled. Returns true on success, false on failure.
By default, auto-commit is on for a connection. Disabling auto-commit is equivalent with starting a transaction.
