Hi,

I've got a really weird problem in (ofcourse) SQL.

I have a table(test):

ID     Total    Amount
1      10       3
2      10       2
3      10       1
4      10       0

Now I want to execute the following code:

SQL

SELECT *
FROM test
WHERE Total / Amount = 5

But if I run this query it will give a "Divide by zero error encountered" because of the last record where it will try to calculate "10 / 0". Of course this doesn't work, but there is no way to get it to work, tried this:

SQL

SELECT *
FROM 
(
   SELECT *
   FROM test
   WHERE Amount > 0
) a
WHERE a.Total / a.Amount = 5

But even that doesn't work.

Please help...
