Can I sum a fieldname using the CASE stmt as follows:
when the item-group = 'A', sum as is;
when the item-group = 'B', multiply by -1 and then sum?
How is this best accomplished?
Must I have two select stmts, one for the 'A' group and another for the 'B' group?
Or can I somehow use the CASE stmt to sum each case differently?
Or a better way?
Thanks
