RE: SQL dividing the sum of two results on a select

Dave,

AFAIK, SQL performs integer division, meaning it rounds to the nearest
integer value.
If your first sum is smaller than the second one, you'll always get a result
of zero.

So, check your sum values independently and make sure that's not the case.
Another thing you can try is casting the values within the sum function to
floats, i.e. SUM(FLOAT(field1)).  Division should then return the real
division (with decimal points and such).
