Powershell Error Attempted To Divide By Zero

technical pains on SQL Server. FAQ: Why does the “Attempted to divide by zero” error still happen? ★★★★★★★★★★★★★★★ SQL Server Forum Support TeamFebruary 28, attempted to divide by zero c# 20113 Share 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 ssrs #error divide by 0 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, 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 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, 2013 at 5:59 am Much needed article to avoid confusion with "IIF" , Thanks !!!

Author Posts April 17, 2015 at 4:57 am #24395 Anonymous Hi Guys, I am writing the below code is to reboot all the DAG nodes in a given DAG. I am in middle of this task and encountering an issue with PS 2.0 vs 4.0. Initially I started writing my code in one of the exchange server which is equipped with PS 2.0. Because of screen size limitations of this VM and https://blogs.msdn.microsoft.com/sqlforum/2011/02/28/faq-why-does-the-attempted-to-divide-by-zero-error-still-happen/ to fix the attached bugs, I configured PSSession on my host machine which is running on Win 8.1 (PS 4.0). Surprisingly when I just ran the sane code against on PS 4.0 it started working with out any issues. to confirm I went back and ran the same code again on 2.0 still issue persists. Please help me to fix this https://powershell.org/forums/topic/attempted-to-divide-by-zero/ issue. You can just run the script with an invalid host name which will result the issue (on 2.0). Also comment on my coding standards which I want improve. Function MaximizeWindow # Function to check and adjust current PS console window sizes. { Write-Verbose "Window Maximize : Started."

functions. The next area where Powershell suprises new users is in its approach to error handling. Fortunately, there are some useful workarounds for making the surprising default behavior work more like you would expect. While learning Powershell, I was trying to create a deployment script. The script needed to perform several tasks including, copying the deployment package to the target machine, setting up services, and the like. While testing it out locally, I would deliberately cause certain steps to fail in order to ensure that the user of the script would be clearly alerted to failures. To my surprise, when I caused exceptions to be thrown, the script would happily continue on to the next step, ultimately printing a success message to the user. Consider this example: What the heck just happened? If you can't rely on uncaught exceptions to stop execution, how can you reliably deal with failures? What if we throw an exception and then blindly move along to a subsequent step that depends on the success of previous steps? Powershell reintroduces VB's "ON ERROR RESUME NEXT", but goes one step further by making it the default! Abandon all hope, ye who etc, etc. To make Powershell error handling work more like error handling in other .NET languages, we can set $global:ErrorActionPreference = "Stop" at the start of our script. With this variable set, uncaught exceptions thrown by Powershell code will cause the whole script to stop. Altering our example with this line, we get the output that we originally expected: This solves most of our problem: the behavior of Powershell code that throws errors. Unfortunately, it doesn't help us when we invoke an external executable that fails in the middle of our script. In my next post, I'll show you how to address the failure of external executables. @plioi :: archive :: fixie :: parsley :: rook © 2011-2013 Patrick Lioi
