Release 10.1A: OpenEdge Data Management:
SQL Reference

ROLLBACK

Ends the current transaction and undoes any database changes performed during the transaction.

Syntax

ROLLBACK [ WORK ] ;

Notes

Under certain circumstances, SQL marks a transaction for abort but does not actually roll it back immediately. Without an explicit ROLLBACK, any subsequent updates do not take effect. A COMMIT statement causes SQL to recognize the transaction as marked for abort and instead implicitly rolls back the transaction.
SQL marks a transaction for abort in the event of a hardware or software system failure. This transaction is rolled back during recovery.

Authorization

None
