Mike,

level, in production for over 6 years, relying on :
- PKs or CKs
- timestamp field

Say I've got tables on a server that are "lookup" libraries, and by
that, I mean the change somewhat infrequently. Instead of always
searching those tables on the server, I'd like to pull them locally
for faster processing---BUT I DON'T WANT TO PULL THEM EVERY TIME WHEN
NOTHING HAS CHANGED. What's the best way to achieve this, trying to
only update locally when something has changed on the server table? I
was initially thinking looking at the CHECKSUM on the server table,
keeping that locally in some sort of lookup table of its own, and only
updating the local table when that checksum value is different. Now I
don't want to get as granular (yet) as a row-by-row comparison, since
these tables (maybe 10) will most likely have no more than a few
thousand rows.
Ideas?
tia,
