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?
