It's an internal Management Studio error, and I am not entirely sure  
  
what method/prop it tries to call.  
  
If you do the same from sqlcmd (or some other client), it works OK.

Sure, but this is the "usual" SSMS bug. Management studio is doing some  
  
weird stuff, not SQL Server.

Hi,  
  
According to my previous posts about controlling NULL value in Parse method,  
  
I have another question:  
  
When I perform a SELECT * (without using ToString() method) I get this  
  
error:  
  
"An error occurred while executing batch. Error message is: Data is Null.  
  
This method or property cannot be called on Null values"  
  
I'd like to know that which method/property cause this error. In other  
  
words, what does SELECT * call?  
  
Thanks every body who participated in solving my previous problem!

Hello Leila,  
  
Well, let's see the full query, but normally a select doesn't call any method,  
  
it just emits the binary serialization of the object rendered as a hex string.  
  
Thank you,
