Generate 'calculated values' for rows within Stored Procedure

I'm having a problem with generating a 'calculated' percentage value as
noted in the sample output below:
#######
Luxury 822 .34602709630
Standard 433 .34602709630
Custom 397 .34602709630
Modified 285 .34602709630
Other 222 .34602709630
More... 676 .34602709630
#######
The 'VP_VClass' column (left) correctly shows each classification, and
provides the correct count for each. However the percentage for each
classification is shown 'incorrectly' as it should be a percentage for each
instead of for the 'sum' of the classifications count, like so:
#######
Luxury 822 .10032954961
Standard 433 .05284999389
#######
The SP is as follows, where the function [dbo.udf_Current_InventoryFunct
ion
()] provides the 'total' count (which in the examples above is 8,193).
#######
ALTER PROCEDURE dbo.usp_VClass_Breakdown
AS
SELECT TOP 100 PERCENT VP_VClass, COUNT(VP_VClass) AS CountOfVP_VClass,
(SELECT CAST(COUNT(VP_VClass) AS NUMERIC)
FROM dbo.vw_VClass_BreakdownView
WHERE (Active = 1) AND (Current = 1)) /
(SELECT *
FROM dbo.udf_Current_InventoryFunction
()) AS Expr1
FROM dbo.vw_VClass_BreakdownView
WHERE (Active = 1) AND (Current = 1)
GROUP BY VP_VClass
ORDER BY COUNT(VP_VClass) DESC
#######
Any thoughts or suggestions would be appreciated. Thanks.
Message posted via http://www.droptable.comHi,
The Query can be re-written as:
=============================
ALTER PROCEDURE dbo.usp_VClass_Breakdown
AS
SELECT VP_VClass, COUNT(VP_VClass) AS CountOfVP_VClass, COUNT(VP_VClass) /
udf_Current_InventoryFunction() PercentOfVP
FROM dbo.vw_VClass_BreakdownView
WHERE (Active = 1) AND (Current = 1)
GROUP BY VP_VClass
ORDER BY COUNT(VP_VClass) DESC
================
I believe this addressed your question. If there are any more problem please
revert back
thanks and regards
Chandra
