NAME

       END - commit the current transaction

SYNOPSIS

       END [ WORK | TRANSACTION ]

   INPUTS
       WORK

       TRANSACTION
	      Optional keywords. They have no effect.

DESCRIPTION

       END is a PostgreSQL extension, and is a synonym for the SQL92-compatible COMMIT [commit(7)].

   NOTES
       The keywords WORK and TRANSACTION are noise and can be omitted.

       Use ROLLBACK [rollback(7)] to abort a transaction.

USAGE

       To make all changes permanent:

       END WORK;

COMPATIBILITY

   SQL92
       END is a PostgreSQL extension which provides functionality equivalent to COMMIT [commit(7)].

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.
