I'm not sure if my second email made it through; I haven't seen it on the
website yet. But, basically, what I am asking is this:
-is it true that when looping over query results in a plpgsql
for..in..execute loop, several records are stored in memory at one time?
and if so, then I am wondering:
-if I then update one of the records currently in memory, are these
changes visible when the loop gets to it?
I hope that someone can tell me these things.
Thanks,
Meghan

Can you tell us more about the app? Sounds like an ERP allocation or
something like that.
