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))
