Can I Sum and Subtract In One SQL Statement?

I am using Dreamweaver with ASP.
I have three fields where I have to sum two fields and then subtract the total from the third field. (Customer1 + Customer2) then subtract from Total Inv$

The select statement I think, would be something like this, BUT this one DOES NOT work.

SELECT SUM(Total Inv$)-(Sum(Customer1+Customer2))
WHERE Date=Date()

Any way of doing this?

Thank you...

How is it not working ... wrong results or error?

Try this (use brackets around fields containing spaces or special characters).  I'm assuming all these fields are numeric:


SELECT SUM([Total Inv$])-(Sum(Customer1) + Sum(Customer2))
WHERE Date=Date()

select field3 - (field1+field2) from mytable

This will give you the result in each row of the table. If you need the total of it all, then

select sum(field3 - (field1+field2) ) from mytable
