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.

SEE ALSO

       BEGIN(7), COMMIT(7), ROLLBACK(7)
