ROLLBACK

Name

ROLLBACK -- abort the current transaction

ROLLBACK [ WORK | TRANSACTION ]

ROLLBACK rolls back the current transaction and causes all the updates made by the transaction to be discarded.

Use COMMIT to successfully terminate a transaction.

Issuing ROLLBACK when not inside a transaction does no harm, but it will provoke a warning message.

To abort all changes:

ROLLBACK;

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