update tblcase set merchandisetotal =
(
COALESCE(( SELECT sum(m.quantity::numeric * m.amount) AS merchandiseamount
FROM tblmerchandise m
WHERE m.caseid = tblcase.caseid AND m.clientnum::text =
tblcase.clientnum::text), 0.0)
)
I tried running the above and it wants to do a sum on all the records in
tblcase instead of just the one being updated, what am I doing wrong?

Put the coalesce inside the select:
update tblcase set merchandisetotal =
(SELECT COALESCE(sum(m.quantity::numeric * m.amount),0.0) AS
merchandiseamount
FROM tblmerchandise m
WHERE m.caseid = tblcase.caseid AND m.clientnum::text =
tblcase.clientnum::text)

You're most probably missing a Where clause after the parentensis. see:

I am not updating 1 record.
I have : WHERE m.caseid = tblcase.caseid AND m.clientnum::text =
tblcase.clientnum::text)
Which should do the aggregate on the record that is being updated (least as
I understood it).
It should update all record in case with either 0 if there are no
merchandise records or do a sum of the merch records for the case being
updated.

I also never heard back on the merge join issue (why do I need to specify
them off on one machine and it runs faster on the other).
I am guessing it is memory related and config related, but I am about to
give up on postgres as I am just not getting all my views to run fast
enough.
You guys could say my views are bad SQL design etc, but they run fine in
MSSQL. I don’t mind visiting each one to make them better, but I am just not
able to increase the speed on all of them. The last one about assoc finally
did run in 3 secs with merge joins off which is pretty fast, but now I have
others that seem pretty simple to me and yet run very slow.
