END(7)							  PostgreSQL 9.2.7 Documentation						    END(7)

NAME

       END - commit the current transaction

SYNOPSIS

       END [ WORK | TRANSACTION ]

DESCRIPTION

       END commits the current transaction. All changes made by the transaction become visible to others and are guaranteed to be durable if a
       crash occurs. This command is a PostgreSQL extension that is equivalent to COMMIT(7).

PARAMETERS

       WORK, TRANSACTION
	   Optional key words. They have no effect.

NOTES

       Use ROLLBACK(7) to abort a transaction.

       Issuing END when not inside a transaction does no harm, but it will provoke a warning message.

EXAMPLES

       To commit the current transaction and make all changes permanent:

	   END;

COMPATIBILITY

       END is a PostgreSQL extension that provides functionality equivalent to COMMIT(7), which is specified in the SQL standard.

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.
