Commits the current transaction.

Synopsis

COMMIT [WORK | TRANSACTION]

Description

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.

Parameters

WORK | TRANSACTION

Optional key words. They have no effect.

Notes

Use ROLLBACK to prematurely end a transaction.

Issuing COMMIT 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:

COMMIT;

Compatibility

The SQL standard only specifies the two forms COMMIT and COMMIT WORK. Otherwise, this command is fully conforming.
