it seems only use in Table Per Concrete Class,if a class set polymorphism="implicit",when select from his child class or parent class,the clall can be selected.this is the default value of the 'polymorphism'.else if the class set polymorphism="explicit",only select from it's name then it can be select ,selecting  from his child class or parent class don't return it.
