Ssrs Division By Zero Error
favorite 5 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, Fields!SomeOtherField.Value / Fields!SomeField.Value) Which should be pretty self-explanatory. If "SomeField" is zero, set the text box value to zero, else set it to "SomeOtherValue / SomeValue". What has us stumped is that the report still throws a runtime exception "attempted to divide by reporting services divide by zero error zero" even though the above expression should prevent that from happening. We fiddled a bit with the expression just to make sure that the zero-check is working, and =Iif(Fields!SomeField.Value = 0, "Yes", "No") works beautifully. Cases where the data is in fact zero resulted in the textbox displaying "Yes" and vice versa. So the check works fine. My gut feel is that the Report rendering engine throws the exception at run-time, because it "looks" as if we are going to divide by zero, but in actual fact, we're not. Has anyone run into the same issue before? If so, what did you do to get it working? ssrs-2008 share|improve this question asked Mar 29 '11 at 11:32 tobias86 3,56511125 add a comment| 4 Answers 4 active oldest votes up vote 46 down vote accepted 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. share|improve this answer answered Mar 29 '11 at 11:44 MartW 9,73022952 2 Awesome, that did the trick. Thanks! –tobias86

So I changed the expression to this: =IIF(Fields!TotalSlots.Value > 0, Fields!TotalPrice.Value/Fields!TotalSlots.Value,"unknown") but I'm still getting a divide by zero error. How do I work around this zero divisor issue. sql reporting-services ssrs-2008 share|improve this question edited May 3 '12 at 15:13 Diego 17.8k63887 asked May 3 '12 at 13:45 jsmith 26721023 add a comment| 4 Answers 4 active oldest votes up vote http://stackoverflow.com/questions/10432714/divide-by-zero-null-workaround-in-ssrs-2008-report 12 down vote accepted The VB IIF evaluates all arguments, so it will throw an error if any argument throws an error: Your formula can be written as: =IIF(Fields!TotalSlots.Value > 0, Fields!TotalPrice.Value / IIF(Fields!TotalSlots.Value > 0, Fields!TotalSlots.Value, 1 ), "unknown") Then even when TotalSlots is zero, the formula still won't encounter a division problem. share|improve this answer edited May 4 '12 at 14:12 answered May 3 '12 at 16:39 Jamie F 14.7k33052 1 It may not apply here, but what about cases where the divisor can be negative? –Homer Jul 10 '13 at 14:52 2 Replace both occurences of > 0 with <> 0 and you should be fine for negative divisors. –Jamie F Jul 10 '13 at 15:06 add a comment| up vote 17 down vote Jamie F's answer is correct. As a tip, you can add a function to your report code to make the division a bit easier to implement in multiple cells, e.g. Public Function Divider (ByVal Dividend As Double, ByVal Divisor As Double) If IsNothing(Divisor) Or Divisor = 0 Return 0 Else Return Dividend/Divisor End If End Function You can then call this in a cell like so: =Code.Divider(Fields!FieldA.Value, Fields!FieldB.Value) share|improve this answer edited May 4 '12 at 2:19 answered May 4 '12 at 1:28 Nathan 6,33221734 add a comment| up vote 1 down vote I don't think your error is on the calc
technical pains on SQL Server. FAQ: Why does the “Attempted to divide by zero” error still happen? ★★★★★★★★★★★★★★★ SQL https://blogs.msdn.microsoft.com/sqlforum/2011/02/28/faq-why-does-the-attempted-to-divide-by-zero-error-still-happen/ Server Forum Support TeamFebruary 28, 20113 0 0 0 Symptom I have 2 decimal data fields (Field1 and Field2) in a dataset, and use the expression with IIf function below to calculate the quotient. If the Field1 is not zero, the divide expression within the true part will be executed. Otherwise, just 0 will be returned. =IIf(Fields!Field1.Value<>0, Fields!Field2.Value/Fields!Field1.Value, divide by 0) However, why I am still getting "#Error" when Field1 is zero? The error message is as follows: [rsRuntimeErrorInExpression] The Value expression for the textrun ‘Textbox6.Paragraphs[0].TextRuns[0].TextRuns[0]' contains an error: Attempted to divide by zero Resolution The cause of this error is that the IIf function always evaluates both the true part and the false part, even though by zero error it returns only one of them. This means both the true part and the false part need to be evaluated. In order to resolve this issue, you need to use a nested IIf function to avoid the zero-divisor in any rate. =IIf(Fields!Field1.Value=0, 0, Fields!Field 2.Value/IIf(Fields! Field 1.Value=0, 1, Fields! Field 1.Value)) After that, you will get the correct result whether Field1 is 0 or not. Workaround You can also use custom code to prevent errors caused by dividing by zero. Select click Report Properties on the Report menu. Click the Code tab and enter the following code in the Custom Code box: Function Divide(Numerator as Decimal, Denominator as Decimal) If Denominator = 0 Then Return 0 Else Return Numerator/Denominator End If End Function After that, set the expression to be: =Code.Divide(Fields!Field2.Value, Fields!Field1.value) More Information IIf Function: http://msdn.microsoft.com/en-us/library/27ydhh0d(v=VS.90).aspx Applies to Reporting Services 2005 Reporting Services 2008 Reporting Services 2008 R2 Tags FAQs SSRS Comments (3) Cancel reply Name * Email * Website SathyanarrayananS says: October 11,
