We need more information than that. Please give us more information regarding what version you're using, how you use this code (as you specify a generic type)

With more information I meant: a piece of code we can use to reproduce your problem, you gave 2 lines of code and nothing how you call that code, what the context is of that code. Have you tried enabling tracing to see which query is produced? https://www.llblgen.com/Documentation/5.8/LLBLGen%20Pro%20RTF/Using%20the%20generated%20code/gencode_troubleshootingdebugging.htm
