Autocommit command




Turns the connection's auto-commit mode on or off. JDBC specifies that the default auto-commit mode is ON. Certain types of processing require that auto-commit mode be OFF. For information about auto-commit, see the Derby Developer's Guide.

If auto-commit mode is changed from off to on when there is a transaction outstanding, that work is committed when the current transaction commits, not at the time auto-commit is turned on. Use Commit or Rollback before turning on auto-commit when there is a transaction outstanding, so that all prior work is completed before the return to auto-commit mode.
