I want to return only the sum total of each of the following two columns generated by this query, but when I wrap them in SUM() I get an error stating that I can't use an aggregate function on an aggregate or subquery.
Is there another approach that I might take to sum these?
SELECT CASE soitem.fmultiple
WHEN 1 then
(SELECT funetprice FROM sorels
WHERE (sorels.fsono = shmast.fcsono)
AND sorels.frelease
= SUBSTRING(shitem.fsokey,10,3)
AND sorels.fenumber
= shitem.fenumber) * shitem.fshipqty
ELSE
(SELECT top 1 funetprice FROM sorels
WHERE (sorels.fsono = shmast.fcsono)
AND sorels.finumber
= soitem.finumber) * shitem.fshipqty
END as ExtPrice,
CASE CAST((shitem.fshipqty) as int)
% nullif(CAST(inmast.fnusrqty1 as int),0)
WHEN 0 then
(CAST((shitem.fshipqty) as int) /
nullif(CAST(inmast.fnusrqty1 as int),0))
ELSE
(CAST((shitem.fshipqty) as int) /
nullif(CAST(inmast.fnusrqty1 as int),0)) + 1
END as BoxCount
