# 2834 Columns Incorrectly Allowed with Aggregate Functions in Expressions in SQL Statements

The following two lines from above query do not produce correct results:

(p.StockOnHand) * SUM(sd.SaleQuantity) AS test2,
SUM(sd.SaleAmount) / StockOnHand AS test3

* and / do not work across table fields...they result in 0
if you put in a + or - then only one of the fields is used.This is also incorrect.

SELECT
p.ProductCode,
p.ProductCode,
p.Barcode,
p.RetailPrice,
p.LastBuyPrice,
p.StockOnHand, 
SUM(sd.SaleQuantity) AS units,
SUM(sd.SaleAmount) AS cogs,
SUM(sd.SaleQuantity) * SUM(sd.SaleAmount) AS test,
SUM(sd.SaleQuantity) / SUM(sd.SaleAmount) AS test1,
(p.StockOnHand) * SUM(sd.SaleQuantity) AS test2,
SUM(sd.SaleAmount) / StockOnHand AS test3
FROM Product p
INNER JOIN SaleDetail sd ON p.ProductCode = sd.ProductCode
GROUP BY p.ProductCode
ORDER BY p.ProductName

Comments and Workarounds

These types of expressions should not be allowed, since they do not make any sense and violate SQL standards. Only aggregates, functions, and constants can be used together in any expression that contains an aggregate function call.
