RE: SQL Select Question

Jeff,

Try rearranging your statement like this.

SELECT sum(Case SbTypE WHen 'O' Then SBQSHP Else (SBQSHP * -1) End)
FROM VSADETL
WHERE SBCmp = 1 and SbInv = 328258 and SbCSIT = 'PR PR026'

I haven't tested it but I'm pretty sure I have done this in the past.

Subject: SQL Select Question

I have a file consisting of the following fields:
Invoice
Type
Item
Quantity

When the type is 'O', the quantity should be treated as a positive number, otherwise as a negative.
I would like to be able to select the total quantity for a specific invoice and item using SQL.
When I tried to do this using CASE for the Type field, I get an error that the field is not valid since it is not in my group by.

The SQL that I get an error on is:
SELECT Case SbTypE WHen 'O' Then SUM(SBQSHP) Else SUM(SBQSHP *
-1) End FROM VSADETL WHERE SBCmp = 1 and SbInv = 328258 and SbCSIT = 'PR PR026'


Is there a way to do this in one statement?

Thanks,
