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
