SSRS 2008 - Dealing with division by zero scenarios

Question

We\'re running into a problem with one of our reports. In one of our tablixes a textbox has the following expression:

=Iif(Fields!SomeField.Value = 0, 0, Fie         


        

Answer 1

IIf will always evaluate both results before deciding which one to actually return.

Try

=IIf(Fields!SomeField.Value = 0, 0, Fields!SomeOtherField.Value / IIf(Fields!SomeField.Value = 0, 1, Fields!SomeField.Value))

This will use 1 as the divisor if SomeOtherField.Value = 0, which does not generate an error. The parent IIf will return the correct 0 for the overall expression.
