ROLLBACK(7)		 PostgreSQL 17.5 Documentation		   ROLLBACK(7)

NAME
       ROLLBACK	- abort	the current transaction

SYNOPSIS
       ROLLBACK	[ WORK | TRANSACTION ] [ AND [ NO ] CHAIN ]

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.

       AND CHAIN
	   If AND CHAIN	is specified, a	new (not aborted) transaction is
	   immediately started with the	same transaction characteristics (see
	   SET TRANSACTION (SET_TRANSACTION(7))) as the	just finished one.
	   Otherwise, no new transaction is started.

NOTES
       Use COMMIT to successfully terminate a transaction.

       Issuing ROLLBACK	outside	of a transaction block emits a warning and
       otherwise has no	effect.	 ROLLBACK AND CHAIN outside of a transaction
       block is	an error.

EXAMPLES
       To abort	all changes:

	   ROLLBACK;

COMPATIBILITY
       The command ROLLBACK conforms to	the SQL	standard. The form ROLLBACK
       TRANSACTION is a	PostgreSQL extension.

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