Simple way to prevent a Divide By Zero error in SQL

Question

I have a SQL query which used to cause a

Divide By Zero exception

I\'ve wrapped it in a CASE statement to stop this fr

Answer 1

I'm using NULLIF bit differently, because in some cases I do have to return some value. Usually I need to return 0 when there is a divide by zero error. In that case I wrap whole expression in ISNULL. So it would be:

Percentage =  ISNULL(100 * ClubTotal / NULLIF(AttTotal, 0), 0)

The inner part is evaluated to NULL and then ISNULL replaces it with 0.
