Using Oracle Flashback Query

Question

So, this is a very powerfull tool, but useless if you have a 3-tire application and using a persistent connection feature.
So in most cases you'll have only one Oracle user used to connect. It would be great if the flashback_transaction_query view can be extended with a CLIENT_INFO or CLIENT_IDENTIFIER fields from the session. Hope, this is not too hard to code... This information is VERY usefull in case you have invistigation of who, why and what for had changed some information.

Flashback Query does not work through DDL operations that modify columns, or drop or truncate tables
