HQL 删除问题
HibernateUtil   hibera=new   HibernateUtil();
                          Session   session=hibera.currentSession();
                          Transaction   tx=session.beginTransaction();
                String     id   =(String)   request.getParameter( "plane_id ");
                String   sql= "delete   Plane   p   where   p.id=id   ";
                Query   query   =   session.createQuery(sql);
                query.executeUpdate();
                tx.commit();
           
执行后报
hibernate.QueryException:   query   must   begin   with   SELECT   or   FROM:   delete   [delete   ems.hibernate.Plane   p   where   p.id=id   ]
