ROLLBACK()			 SQL Commands			    ROLLBACK()



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.

SEE ALSO
       BEGIN [begin(7)], COMMIT	 [commit(l)],  ROLLBACK	 TO  SAVEPOINT	[roll-
       back_to_savepoint(l)]
