I'm trying to use T-SQL to return the relative percentage of two summed values when I divide the values into each other, but I always get 0. Here is my stored proc
CREATE PROCEDURE dbo.SC_PMPULL

(
      @startdate datetime,
      @enddate datetime
)
AS
BEGIN

SELECT underwrtr,COUNT (received)as received,count(denied)as denied,fullname
 
INTO #tmpPull
FROM dbo.TestPull
WHERE received BETWEEN @startDate and @enddate and received is not null
GROUP BY underwrtr,fullname, denied,received
Select P.fullname, coalesce(sum(P.received), ' ')as [U/W Received],coalesce(sum (P.denied) ,' ')as [U/W Denied] , P.underwrtr,(sum(P.denied) /sum(P.received) )as PercentageDenied--,P.month,P.year,P.monthvol
   From #tmpPull  P
     Group by P.fullname,P.underwrtr
drop table #tmpPull


END

Hi

Your values are Ints - you need to cast them as DECIMAL (or NUMERIC) e.g.:

CAST((sum(P.denied) AS NUMERIC, 4, 3) /sum(P.received) )as PercentageDenied
