Thanks Julio. dba_tab_modifications returns no rows with today's timestamp :) From: Julio Aguilar-Chang [mailto:jachang@xxxxxxxx] Sent: Monday, August 03, 2009 2:39 PM To: Jiang, Lu Cc: ORACLE-L Subject: Re: Find which table's data has been changed in last five hours. Try dba_tab_modifications. It has columns such as the table_owner, table_name, number of inserts/updates/deletes, and the timestamp.

Is there a way to find which table's/schema's data has been changed in last five hours, so that I could export the schemas/tables before flashback and import them after flashback?
