Обсуждение: timestamp of a row

Dear all,
             I look into mails-archive but I didn't find any hint for this question: is there a way to retrieve the timestamp of the creation/last modification of a row in a table?

Many thanks and regards,
                                       Marco Bomben

I don't believe there is.  I wanted to do something similar, but the
only way I found of doing it was to create a trigger on the table
which updates a timestamp column on the row being updated.

Dear Thom,
                     thanks for the suggestion. I will look for 'trigger' into documentation.

Regards,

Of course there is. You should create an auditing trigger to record the
time of the modification, the primary key of the row that was modified
and the nature of the modification itself.
