That is exactly what my design would be given the
option. Thanks for concurring.
I have also been asked if the trigger can fire
off a pop-up box in the app to ask for a reason
for change that needs to be in the audit record
as well. Yeah, really... that's what they want.
Another option suggested for tables with heavy
updates is to record the full insert and only the
column deltas on updates. Okay, lets compare all
87 columns to see if the new value is the same as
the old value. Just throw all kinds of junk in
the trigger so it effects its performance.
My origianl question was for any links to
whitepapers on trigger devlopment.
Thanks...
