title: Delete with QueryOver?
body: <p>I would like to improve my code when deleting  a group of objects in NHibernate (V3).
  Currently, I iterate on a retrieved collection and I call delete on each object. This generates n+1 SQL statements.</p>
  
  <p>I notice that NHibernate Session provides this method : <strong>Delete(string query)</strong></p>
  
  <p>By using this method I think I can do the same thing with a single SQL statement.</p>
  
  <p>Do you know if there is a way to combine this method with QueryOver API to avoid HSQL ?</p>
