If the SELECT doesn't match any data then no data should be inserted 
into the table, and a result set with a single value of 0 will be 
returned.  The original poster should remove the parenthesis.  If 
removing the parenthesis causes a NULL exception, I'd be interested in 
seeing the full query and the layout of the table(s) so I may attempt to 
reproduce the error.  Posting an SQL script that reproduces the error 
would be great.
