Question

I really couldn’t figure out a good title for this question, but I have a problem that I’m sure you can help me with!

I have a query which outputs something like this:

Month | Year | Subcategory | PrivateLabel | Price
-------------------------------------------------
  1   | 2010 | 666         | No           | -520
  1   | 2010 | 666         | No           | -499,75
  1   | 2010 | 666         | No           | -59,95
  1   | 2010 | 666         | No           | -49,73
  1   | 2010 | 666         | No           | -32,95

I want to SUM on the price because all the other data is the same. I thought I could do this with SUM and GROUP BY, but I can’t figure out how to do it or at least it doesn’t output the right result.

The query is an inner join between two tables, if that helps.

Answer 1

select
   month
   ,year
   ,subcategory
   ,privatelabel
   ,sum(price) as [total sales]
from
   a inner join b ...
where
   any where clauses 
group by
   month
   ,year
   ,subcategory
   ,privatelabel

should work if i am understanding you correctly.. every colum in the select either needs to be part of the group by or an aggregate function on all rows in the group

added a fiddle.. mainly as i didn’t know about he text to DDL functionality and wanted to test it 😉 (thanks Michael Buen)

note the where clause is a place holder..
