Oracle: Arithmetic operation resulted in an overflow

c# .net oracle

Solution 1

Shoot now I recall that I have seen this before. The Oracle client is 32-bit only. And so my .NET app needs to be x86 compiled. So annoying! And the message is so deceptive.

bug in the Oracle ODBC driver. It affects the versions: 10.2.0.4 to 11.2.0.1 of Oracle and only the 64 bit driver (not the 32 bit driver).

I love coding! The way I get to do what I love is by specializing in integration data between Project Management and ERP systems. For example, I integrate Primavera with JD Edwards. Or PeopleSoft, or Timberline, or, heck, even an Excel spreadsheet. And I write tools and wrapers to make the user experience better with these systems. Most of the work I do is for the Windows environment, so in C# and IIS on the server side. Recently I've been doing a lot of SPA work, so learning alot of JavaScript and that whole ecosystem of libraries and tools. It's pretty fun, and often blows my poor statically-typed, object-oriented mind!

My query pulls two strings - no numeric types at all, yet the Oracle client gives me the exception above. Any ideas?

Here is the query - all fields are strings:

 SELECT project_name 
        , project_title
        , project_name as Job2   
        , project_name as Job1  
 FROM PROJ

Here is the exception:

System.OverflowException: Arithmetic operation resulted in an overflow.

Your solution worked for a similar issue. I was getting this error on IIS 8 where the app pool did not allow 32 bit applications. Some I set that property to true, the error went away. Thanks!

Just to add a little more information: if you are deploying to a server with IIS 8, and Sharepoint 2013, the "Enable 32-Bit Applications" flag won't work by default, and will instead crash your application. This article has a fully working solution. (I came across this problem with our IBM System i at work, and the IBM driver for it.)
