Hi Aviv !
Thanks for your reply !
Yes , i thought of this "snapshot log" option . 2 problems :
1) performance overhead - for each DML on my table , i have a DML on the MLOG$_ (snapshot log) table , carried out by a trigger. 2) For each access to the rows in my original table , i need to join with the MLOG$_ table (in order to filter out the neccessary timestamps) - another performance overhead.
3) I'm wondering whether this modification time is stored somewhere in the data dictionary.
Thanks a lot !

Dear gurus !
Is there a way to know the time of insert/update for each row in a table ? Or , which rows in a table were inserted/updated since a certain time. ( Sort of find ... -mtime ... for UNIX files) . I CAN NOT modify the structure of the table , i.e. i CAN NOT add a timestamp or other column , just need to deal with what is present. Thanks a lot for your help !!!
