Subject: query; check for zero and floats

Message-ID: <20060401010317.tbza82opw0c0ccg0@webmail.weaktight.com> (raw)
I'm trying to do a simple query and I'm not sure how to get it to work:
SELECT SUM(x0 + y0 + z0) / SUM(x2 + y2) AS A1, SUM(x1 + y1 + z1) / SUM(x3 + y3)
AS A2
FROM test
Problems:
1. All variables are integers. When it does the division, it returns an
integer, but I want a float. (I've tried numerous things to no avail)
2. If SUM(x2 + y2) == 0; there is a divide by zero error. How do I check and
pass on zeroes?
Thanks,
Vince.
