Alex,
I did a describe on sys.dba_tab_modifications and it shows a lot of info. I select * from the view and no rows were returned but I have inserted and truncated a lot of data this morning. Does it matter the userid doing the work? I have created a userid that has the insert, del, update, sel privs on the tables that get changed each morning.
OS linux 7.0
Oracle 8.1.7
Your thoughts?

It is not a table - it is a view owned by sys. And it exists only in 8i+

Guys,
can you please confirm to me you found dba_tab_modifications table. I checked both 7.3.4 and 8i versions and I don't seem to find the table. Thank you.

Hi,

Thanks for the clarification. Always welcome.

However you can query the view dba_tab_modifications for checking when and how many
updates/deletes/inserts/truncate have been done on the table. If this is enough, great, don't you think so ?.

Regards.
