Home -> Community -> Mailing Lists -> Oracle-L -> Re: A "modification time" question
Okay, can you add a trigger?
At a prior job, management wanted us not only to track last update/insert but WHAT was done.
so I created a second table, duplicate of the first with addition fields of "trans_date","user" and "action"
then I added a trigger (insert/update/delete) on the original table.
if the action was an insert, I inserted a row into the second table, trans_date=sysdate, user=user and action=I
if a delete, I inserted a row into the second table, trans_date=sysdate, user=user and action=D
if an update, I inserted two roww into the second table, the first had the original row, trans_date=sysdate, user=user and action=O (old values) the second had the new row, trans_date=sysdate, user=user and action=N(new values)
the secondary table could be archived/purged as necessary
