Nested Query Troubles...

Hi All,

Can anybody please tell me if a query such as this (Valid in MS Access)
can work in SQL Server:

SELECT Description, Sum(Total) FROM (
SELECT Description, Total FROM Table_A
UNION ALL
SELECT Description, Total FROM Table_B
UNION ALL
SELECT Description, Total FROM Table_C
)
GROUP BY Description


The group of unions work by themselves, but when I try to nest an outer query to do some a Summation(), I have syntax errors.

Any insight would be greatly appreciated. Thank you.You must supply an alias for your subquery:
SELECT Description,
Sum(Total)
FROM (SELECT Description,
Total
FROM Table_A
UNION ALL
SELECT Description,
Total
FROM Table_B
UNION ALL
SELECT Description,
Total
FROM Table_C) AS SUBQUERY
GROUP BY Description|||Thanks BlindMan, u da man.

:)
