Question

I dont know why this is coming up as invalid and I can not figure it out. I was given a legacy database as my supervisor left and I am in charge until someone comes to replace him. I am trying to run this query…

    SELECT     tblM.guidRId, SUM(dbo.tblCH.curTotalCost) AS curValue
FROM         tblCH INNER JOIN
                      tblM ON tblCH.guidMId = tblM.guidMId INNER JOIN
                      ViewLM ON tblM.strNumber = ViewLM.strNumber
WHERE     (tblM.guidRId = '4d832bc8-1827-4054-9896-6111844b0f26')

The error I keep getting is…Msg 8120, Level 16, State 1, Line 1
Column ‘tblM.guidRId’ is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

Why is this error occuring?

Answer 1

You are forgetting to group guidRId. (you are aggregating the data)

SELECT     
    tblM.guidRId, 
    SUM(dbo.tblCH.curTotalCost) AS curValue
FROM         
    tblCH 
    INNER JOIN tblM ON tblCH.guidMId = tblM.guidMId 
    INNER JOIN ViewLM ON tblM.strNumber = ViewLM.strNumber
WHERE  
    tblM.guidRId = '4d832bc8-1827-4054-9896-6111844b0f26'
GROUP BY tblM.guidRId
