Best way to insert a DateModified in updates

how do i update the date modified Field in my DB. i was thinking of update trigger? i am using ASP 2 with DetailsView for Editing(Updates in SQL term). i can make a Update SP but think that might not be needed

If you use the SP you can define the date now to a variable. @.datenow = GetDate()|||

In the Update procedure, you can just "SET dateModified=GETDATE()".

In my view, Triggers are a little bad in the respect that they are hidden. If you look at a simple SQL statement, you really can't "trace" the code execution completely if your DB has a whole pile of Triggers firing all the time, which means, things might be happening that the SQL statement writer isn't aware of, and that can cause problems.

Of course, their not overall bad, but my personal preference is to use an SP, unless a Trigger is specifically required or for some odd reason more effecient.
