ROLLBACK(7)                      SQL Commands                      ROLLBACK(7)



NAME
       ROLLBACK - abort the current transaction


SYNOPSIS
       ROLLBACK [ WORK | TRANSACTION ]


DESCRIPTION
       ROLLBACK rolls back the current transaction and causes all the updates made by the transaction to be discarded.

PARAMETERS
       WORK

       TRANSACTION
              Optional key words. They have no effect.

NOTES
       Use COMMIT [commit(7)] to successfully terminate a transaction.

       Issuing ROLLBACK when not inside a transaction does no harm, but it will provoke a warning message.

EXAMPLES
       To abort all changes:

       ROLLBACK;


COMPATIBILITY
       The SQL standard only specifies the two forms ROLLBACK and ROLLBACK WORK. Otherwise, this command is fully con-
       forming.

SEE ALSO
       BEGIN [begin(7)], COMMIT [commit(7)], ROLLBACK TO SAVEPOINT [rollback_to_savepoint(7)]
