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 conforming.

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