I hate the answer but anyway Thanks a lot. I was afraid of this but still a bit surprised. Has everyone else access to perfectly designed databases, I haven't? I'm not sure what to do, either your solution (which will work) or try to change the dbSchema, this is not the only example for issues like this. Again, thanks a lot.
