David, Michael-

Personally, I almost never do a REPLACE anymore, but, FWIW, I heard others here suggest that replacing in a table other than is currently selected is best done with IN. As in:

REPLACE TableOrViewName.tLastUpdate with datetime() IN AliasName

Has that been your experience, David?

>You should be able to REPLACE TableOrViewName.tLastUpdate with datetime() this value won't be committed to the table until you TableUpdate().
