How to sum across multiple rows for multiple fields

Question

Can anyone please advise on how to go about writing a SQL query to include the sum for multiple fields across multiple rows by group. I'm using the below query, but it keeps saying that the fields "in the select line are invalid because it is not contained in either an aggregate function or the GROUP BY clause."

    Select ClaimId,InternalICN,BilledAmt, 
           Sum(PayAmt) as TotPayAmt,Sum(COBAmt) as TotCOBAmt,Sum(PrePayAmt) as  
           TotPrePayAmt 
    from CAIDEnc.IntEncTracking.EncounterList
    where BypassFlag = 0 and
     BypassReason = 0
    group by ClaimId, InternalICN

Any advice would be greatly appreciated. Thanks!

Answer 1

BilledAmt is not in the group by clause. You must put it there, or aggregate it with a sum, average or other function.

Answer 2

BilledAmt is not in a aggregate query. When you use group by you can only select aggregates or any field in the group by clause/

Answer 3

Depending on what you really want, you have two options:

OPTION #1: Remove the BilledAmt from the SELECT

Select ClaimId,InternalICN, 
           Sum(PayAmt) as TotPayAmt,Sum(COBAmt) as TotCOBAmt,Sum(PrePayAmt) as  
           TotPrePayAmt 
    from CAIDEnc.IntEncTracking.EncounterList
    where BypassFlag = 0 and
     BypassReason = 0
    group by ClaimId, InternalICN

or

OPTION #2: Include the BilledAmt in the GROUP BY

Select ClaimId,InternalICN,BilledAmt, 
           Sum(PayAmt) as TotPayAmt,Sum(COBAmt) as TotCOBAmt,Sum(PrePayAmt) as  
           TotPrePayAmt 
    from CAIDEnc.IntEncTracking.EncounterList
    where BypassFlag = 0 and
     BypassReason = 0
    group by ClaimId, InternalICN,BilledAmt
