Controlling Autonomous Transactions
The first SQL statement in an autonomous routine starts a transaction. Whenever one transaction ends, the next SQL statement starts the other transaction. All the SQL statements executed as the last commit or rollback make up the present transaction. To control the autonomous transactions, use the statements shown below, that apply only to the present (active) transaction:
(i)COMMIT
(ii)ROLLBACK [TO savepoint_name]
(iii)SAVEPOINT savepoint_name
(iv)SET TRANSACTION
The COMMIT ends the present transaction and makes the permanent changes made during that transaction. The ROLLBACK ends the present transactions and undoes the changes made during that transaction. The ROLLBACK TO undo part of a transaction. The SAVEPOINT names and marks the present point in a transaction. The SET TRANSACTION sets the transaction properties like read/write access and isolation level.
