I believe that is the correct message: you were concatenating a null string to something, and so nullifying the string you were using for execute. In other words, it is not a wrong error message, or it could not have been better since the instruction before the execute was doing what you asked for. I believe in such cases it is better to check against the query string and execute it only if valid.
