Thank you, Carlos.
The Qry I use is created for each call of the routine (done by a timer).
I added the IB_Transaction.commit. And still I am not getting the
correct results. Now I get 1 when I should have 2 and likewise there is
no change as I disconnect from the database (in IBExpert). Still
getting those crazy large Mon$Attachment_IDs, too.
I still suspect that having falsely high IDs means something. As a test
I have a "do while not eof" and look at the
FieldByNAme('mon$attachment_id).asInt64. That is when I notice the 10 to
the 17th power IDs. Like I said they actually are 4 digits long now.
Any other thoughts?
