I did find this post: how do I subtract values from two select statements

but I cannot get it to work on SQL-Server 2008.

I have two basic SELECT statements. No GROUP BYs or anything, just a SELECT, FROM and WHERE.

I would like to subtract one of these SELECTs from the other. Both return one row and column.

Could somebody please help?

SELECT 
    ((SELECT Field1 AS BaseBase FROM Table1
        WHERE Field2 = 'something' 
        AND Field3 = 
           (SELECT Field4 FROM SEL_Function('something','something')) as tab1)
      -     
    ((SELECT Field5 FROM SEL_Function('something','something') as tab2)

    Alright I don’t think the cross apply is necessary fiddle won’t allow functions but check out this fiddle. You will want to swap out the table of the same name with the function. I think you were getting bit by a combination of alias and paren mismatches.
