Amit,
Oh, just what is it you DON'T want the auditors to see???? Usually auditing operates on the principle that nothing is hidden from the auditors. I was just reading about the auditors that audit the CIA.
Are these tables where it is technically possible to revoke PUBLIC?
Okay, you could:
1. Create a new role.
2. Grant the tables in question to that role.
3. Grant that role to everybody except the auditors.
4. Revoke PUBLIC from those tables.
