Question

I’m using this query, but I get an error vdagbk.bedrag and vdagbk.reden .

Problem is, if I would put in in the second SELECT the result would certainly be wrong as it sums the result to many times due to double data in the table.

SELECT TOP (100) PERCENT 
   SUM(P.bedrag) AS ex, 
   C.dosno, 
   C.dosnm, 
   SUM(P.betaald) AS TotBetaald, 
   SUM(CASE vdagbk.reden WHEN 'H' THEN vdagbk.bedrag END)  AS Expr1
FROM         
   dbo.verkopen AS P 
INNER JOIN
   (SELECT DISTINCT 
         dbo.doss.dosno, dbo.doss.dosnm, dbo.verkopen.ino
    FROM dbo.verkopen 
    INNER JOIN dbo.doss ON dbo.verkopen.ino = dbo.doss.ino 
    INNER JOIN dbo.vdagbk ON dbo.verkopen.ino = dbo.vdagbk.ino
    WHERE      
        (dbo.doss.uitvoerder LIKE 'LL') 
        AND (dbo.doss.dosno LIKE '101520')
    GROUP BY 
        dbo.doss.dosno, dbo.doss.dosnm, dbo.verkopen.ino) AS C ON C.ino = P.ino 
INNER JOIN
    dbo.vdagbk AS vdagbk_1 ON P.ino = vdagbk_1.ino
GROUP BY 
    C.dosno, C.dosnm

How can I make this query work ?

Answer 1

You’re giving your table dbo.vdagbk an alias vdagbk_1 here:

INNER JOIN
    dbo.vdagbk AS vdagbk_1 ON P.ino = vdagbk_1.ino

so you also need to use that alias in your SUM() clause here:

SUM(CASE vdagbk.reden WHEN 'H' THEN vdagbk.bedrag END)  AS Expr1

Change this to:

SUM(CASE vdagbk_1.reden WHEN 'H' THEN vdagbk_1.bedrag END)  AS Expr1

and it should work.
