title: SQL Server: Is it possible to cascade update a self referencing table?
body: <p>It would appear that, at least through management studio express, it is not possible to set a foreign key constraint that references the same table to do anything on update or delete.
  I have a table where I would like to cascade updates to null if a row is removed.</p>
  
  <p>Is this possible?</p>
  
  <p>Thanks,</p>
