ROLLBACK(7)             PostgreSQL 9.5.3 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 outside of a transaction block emits a warning and
       otherwise has no effect.

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.
