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.
