ROLLBACK(7)                      PostgreSQL 9.2.24 Documentation                      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(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.

SEE ALSO
       BEGIN(7), COMMIT(7), ROLLBACK TO SAVEPOINT (ROLLBACK_TO_SAVEPOINT(7))
