Hi Foued,
I need more details. The error is from the ASE Database server.
I think it is best to start new dialog since your problem is not relevant to the content of the current thread.
For starters what are the exact versions of ASE, The ASE ADO.NET Provider and what version of Microsoft VIsual Studio and Entity Framework are being used here. What exactly are you doing to get this message?
I will be on vacation all next week.
Cheers,
-Paul
