I am using LLBLGen Pro 3.1 to create a Self Service LLBLGen Pro Framework Project in C# Targeting .Net Framework. The database is DB2 9.7 on 64 bit AIX. Actually, its been working for years. Yesterday, I deployed a build (with no changes to my persistence layer) to my QA server and I started receiving this error. I pointed my development environment at the production DB2 server (don't tell the DBA) and verified that I receive the same error.

If I take the SQL above and run it in the CLI environment, I get a similar error. If I remove the doubled up double quotes, the query executes. *

Hi Steven,

Please provide the exact runtime library version (http://www.llblgen.com/TinyForum/Messages.aspx?ThreadID=7717), or better, update to the latest v3.1 build and check that you are referencing the correct assemblies.

Also, if it works on your dev machine, then something changed on the DB server, investigate further on this.

Regarding my runtime environment: SD.LLBLGen.Pro.DQE.DB2.NET20.dll v2.5.7.820 SD.LLBLGen.Pro.ORMSupportClasses.NET20.dll v2.5.8.1012 IBM.Data.DB2.dll v9.7.0.2 IBM.Data.DB2.9.7.0.dll v9.7.0.2

Also, if it works on your dev machine, then something changed on the DB server, investigate further on this.

I believe you misunderstood my original post. Regardless of what database I point to, I am getting this error. I get it running in debug mode, pointed to both my QA and Prod DB2 Servers. And I also get it if I compile my code and deploy it to the QA server.

I'm confused. In your first post you say you are using v.3.1 But in your last post you report v.2.5

Which of them are you using?

Btw, there was a similar issue solved 2 months ago on v.3.x http://www.llblgen.com/TinyForum/Messages.aspx?ThreadID=21192

I am using LLBLGenPro Version 3.1 Final, Released on March 12th, 2012.

David inquired as to my runtime version to which I posted the version of ever applicable runtime dll. I got the version numbers by right clicking on the dll, going to properties then selecting the details tab.

Have I done something wrong? Am I missing any more pertinent information.

Thanks.

SD.LLBLGen.Pro.DQE.DB2.NET20.dll v2.5.7.820 SD.LLBLGen.Pro.ORMSupportClasses.NET20.dll v2.5.8.1012

The version numbers of the runtime libraries indicate you are using v.2.5

I am sorry for the confusion I was looking in tthe wrong place.

SD.LLBLGen.Pro.ORMSupportClasses.NET20.dll is version 3.1.12.716 SD.LLBLGen.Pro.DQE.SqlServer.NET20.dll is version 3.1.11.706

Then as per my previous post, please download the latest build, of v.3.1. And check this out again. As there was a fix of a similar issue in August and your runtimes are from July.

Is there any reason I shouldn't just upgrade to 3.5?

I upgraded to 3.5 and the error is gone. Thank you for you help.
