end

END(7)								   SQL Commands 							    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 [commit(7)].

PARAMETERS

       WORK

       TRANSACTION
	      Optional key words. They have no effect.

NOTES

       Use ROLLBACK [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 [commit(7)], which is specified in the SQL standard.

SEE ALSO

       BEGIN [begin(7)], COMMIT [commit(7)], ROLLBACK [rollback(7)]
