Question

I’m trying to make a query to retrieve the region which got the most sales for sweet products. ‘grupo_produto’ is the product type, and ‘regiao’ is the region. So I got this query:

SELECT TOP 1 r.nm_regiao,  (SELECT COUNT(*)
        FROM Dw_Empresa
        WHERE grupo_produto='1' AND 
        cod_regiao = d.cod_regiao) as total 
FROM Dw_Empresa d
INNER JOIN tb_regiao r ON r.cod_regiao = d.cod_regiao ORDER BY total DESC

Then when i run the query, MS-Access asks for the “total” parameter. Why it doesn’t consider the newly created ‘column’ I made in the select clause?

Thanks in advance!

Aliases are only usable in the query output. You can’t use them in other parts of the query. Unfortunately, you’ll have to copy and paste the entire subquery to make it work.
