You can use Flashback Version Query to look at all changes to data in a given table, if that helps and if the UNDO is available.

Subject: Database comparisons

List,  

We have an audit finding related to data integrity. I'm looking for a way to detect all database changes on a small test database. Fortunately the environment is well-contained. Typically when we've made application changes, we verify that the data changes are what we expect. The auditors are insisting that we somehow verify there aren't unexpected changes in other tables. The environment is Oracle 10.2.0.4 on Solaris. I have three thoughts:  

1. The test database is freshly loaded from an export. After the tests, take an export and use UNIX "diff" and compare with the import.
2. Log Miner, or somehow more directly inspecting the archive logs.
3. Use some of the new flashback features to detect changes. This just occurred to me and I haven't had time to investigate it.

Has anyone else done anything like this before?  

Dennis Williams
