Viewable by all users 0 In this particular situation, it looks like you want to divide by 1, but to skip rows with zero or NULL and if it is OK select itnbr, Amount, Quantity, case when Quantity <> 0 then Amount / Quantity else 0 end from SomeTable If Quantity is not zero, the division takes place. In that case I wrap whole expression in ISNULL. http://stackoverflow.com/questions/19631017/simple-way-to-prevent-a-divide-by-zero-error-in-sql 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.
Except it's really there and it's just that I was passing in a bad value...but I have no idea. Divide By Zero Error Encountered Excel What if I forgot to re-enable the warnings? Why don't you connect unused hot and neutral wires to "complete the circuit"? Rather than calculating something you state the value to return for the case that AttTotal is zero.
