Re: trying to do an update a bit confused.

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

Subject: [SQL] trying to do an update a bit confused.

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)

)

WHERE <condtion that selects one record>;

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?
