In addition to autonomous transaction, this discrete transaction thing is kinda interesting. From the doc, it says dbms_transaction.begin_discrete_transaction() is used to start a discrete transaction (how to end?), but no details. I need to know if this is suitable for deleting 1 million records from a 50 million records table without undo. Thanks in advance.
