Are you sure that you can't write this in a set-oriented fashion using an update with a subquery:

UPDATE orders SET
total = (SELECT SUM(cnt * cost) FROM orderdetails WHERE orderid = orders.orderid)

>I've been trying to write an SP that has two cursors, the first (outer) I need to be able to do updates with, the second (inner) is read-only. I've DECLAREd the first cursor as follows:

>DECLARE corrCursor CURSOR FOR
> SELECT * from v_Open_Correspondence
> FOR UPDATE Item_Age

>Then I open the cursor and use FETCH NEXT to loop through the items in the View. For each item I open a read-only cursor for a subsidiary table, loop through the related items in the subsidiary table to compute the Item_Age value of the parent item. Once I'm done with the subsidiary table I close that cursor and try to do
