But the original message said there was very little inserted or updated (at
least I think it said updated) and no rules or triggers. I was thinking that
there was something going on here that the poster wasn't aware off. Perhaps the
app does do updates that don't change the data, for some reason, and so the
poster doesn't see any inserts/updates from his reports.
