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

An easy clean way to prevent a divide by zero error is using the report code area.

In the Menu, go to Report > Report Properties > Code and paste the code below

Public Function Quotient(ByVal numerator As Decimal, denominator As Decimal) As Decimal
        If denominator = 0 Then
            Return 0
        Else
            Return numerator / denominator
        End If
    End Function

To call the function go to the the Textbox expression and type:

 =Code.Quotient(SUM(fields!FieldName.Value),SUM(Fields!FieldName2.Value))

In this case I am putting the formula at the Group level so I am using sum. Otherwise it would be:

 =Code.Quotient(fields!FieldName.Value,Fields!FieldName2.Value)
