COMMIT - commit the current transaction
COMMIT [ WORK | TRANSACTION ]
COMMIT commits the current transaction. All changes made by the transaction become visible to others and are guaranteed to be durable if a crash occurs.
WORK TRANSACTION Optional key words. They have no effect.
Use ROLLBACK(7) to abort a transaction. Issuing COMMIT when not inside a transaction does no harm, but it will provoke a warning message.
To commit the current transaction and make all changes permanent: COMMIT;
The SQL standard only specifies the two forms COMMIT and COMMIT WORK. Otherwise, this command is fully conforming.
