Hi guys, sorry for flooding the thread, i made it work with this:

SELECT N.vnd_cod,
SUM((V.ved_comissao / 100) *
I.item_valor) AS ved_porcento,
SUM((P.pro_com_porcento *
I.item_valor) / 100) AS item_porcento,
SUM(P.pro_comissao *
I.item_qtde) AS valor
FROM items_venda I
JOIN vendas N ON (
N.vnd_cod=I.vnd_cod)
JOIN vendedores V ON (
N.ved_cod=V.ved_cod)
JOIN produtos P ON (
I.pro_cod=P.pro_cod)
WHERE V.ved_cod='2'
GROUP BY N.vnd_cod
ORDER BY N.vnd_cod ASC

But i cant make the COALESCE work, i have to get just ONE of this 2 values:

SUM((V.ved_comissao / 100) * I.item_valor) AS ved_porcento, SUM((
P.pro_com_porcento * I.item_valor) / 100) AS item_porcento

But coalesce isnt working :(

I tried this:

SELECT N.vnd_cod,
SUM(COALESCE(((V.ved_comissao / 100) * I.item_valor),((P.pro_com_porcento*
I.item_valor) / 100))) AS porcento,
SUM(P.pro_comissao * I.item_qtde) AS valor
FROM items_venda I
JOIN vendas N ON (N.vnd_cod=I.vnd_cod)
JOIN vendedores V ON (N.ved_cod=V.ved_cod)
JOIN produtos P ON (I.pro_cod=P.pro_cod)
WHERE V.ved_cod='2'
GROUP BY N.vnd_cod ORDER BY N.vnd_cod ASC

It works, but i just get 0.00 on the first SUM :(
