title: SQL Server - lack of NATURAL JOIN / x JOIN y USING(field)
body: <p>I've just been reading up on NATURAL JOIN / USING - SQL92 features which are (sadly?) missing from SQL Server's current repertoire.</p>
  
  <p>Has anyone come from a DBMS that supported these to SQL Server (or another non-supporting DBMS) - were they as useful as they sound, or a can of worms (which also sounds possible!)?</p>
