Re: A modification time question
the answer is it depends. since you can't modify the table, why not put a trigger to put a last updated, etc time into another table. joe Andrey Bronfin wrote: Dear gurus !

RE: A modification time question
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.

RE: A modification time question
If you can't modify the structure to add a timestamp column or add a trigger to insert a timestamp into another table, there's no way I know of to track it. Oracle doesn't track this sort of thing on its own; you need some sort of timestamp field.

Re: A modification time question
Create a trigger on insert/update of zour table and let the trigger write tuple in other table with datetime of modification of ROWID of your table.

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 From: Andrey Bronfin [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Subject: A modification time question Date: Thu, 16 Aug 2001 03:15:49 -0800 Dear gurus !
