The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.

Could be done this way...
Sum( case when item_grp = 'A' then item_value
When item_grp = 'B' then -item_value
Else 0
End ) as summed_value

Subject: SQL SUM(fieldname) - can I use CASE??
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
