In a previous post, I wrote about how to prevent the divide by zero issues in Reporting Services. The problem with the custom code I used was that the code returned the value 0 when one of the numbers is 0 or unknown.
So when the outcoming was NULL, the code returned 0. This result in the value 0 in my reports:
I have found a better code on the internet to prevent the divide by zero error in SSRS.
Public Function Divide(ByVal first As Double, ByVal second As Double) As Double
If second = 0 OR first = 0
Return first / second
Usage in an expression: Code.Divide(Value A, Value B)
Public Function CalcDivision(ByVal Numerator As Object, _
ByVal Denominator As object, ByVal DivideByZeroDefault As Object) As Object
If Denominator <> 0 Then
Usage in an expression: =Code.CalcDivision(Field A, Field B,Nothing)
So it return NULL and not 0! Better solution!
I hope Microsoft will make it easier to fix these kind of thing with less effort. I haven’t tried it in SQL 2014/2016 yet so maybe the already have a solution to prevent Divide By Zero. They should include some cool function by default in SSRS or something like that!
