Greetings,

I'm struggling with a bit of SQL here and am looking for ideas on how to resolve it.

Given the following query:

Select ta.accountname, ta.appealname,
coalesce(CASE WHEN ta.fk_gifttype=1 THEN Sum(ta.appealgiftamount) ELSE 0::decimal END,0) as pledgetotal,
coalesce(CASE WHEN ta.fk_gifttype=3 THEN Sum(ta.appealgiftamount) ELSE 0::decimal END,0) as paymenttotal
FROM ds1.tranappeal ta
GROUP BY ta.accountname, ta.appealname, ta.fk_gifttype
ORDER BY accountname

What I want to end up with is one row per account name with the correct pledge and payment total.

What I'm receiving in most cases is multiple lines per account name. The reason is because I'm being forced to include the fk_gifttype field in the Group By. Because there are other gifttype codes, those rows are being included with zero amounts.

I also tried using a sub select but that didn't work because "appealname" isn't part of a scope. As a result, I received the "total" pledge and payment regardless of appealname.

I'm wonder what other options I might have to get the desired results.

Thank you,

Hello
I may have misunderstood the intent of your query but I think the following is equivalent. If you put the sum on the outside you do not have to group by fk_giftype.
Select ta.accountname, ta.appealname,
sum(CASE WHEN ta.fk_gifttype=1 THEN ta.appealgiftamount ELSE 0::decimal END) as pledgetotal,
sum(CASE WHEN ta.fk_gifttype=3 THEN ta.appealgiftamount ELSE 0::decimal END) as paymenttotal
FROM ds1.tranappeal ta
GROUP BY ta.accountname, ta.appealname
ORDER BY accountname

Thanks

Thanks David. This is exactly what I was looking for.
