Hi all,

Is any one used table inheritance in database with hibernate via JPA? If so, can you suggest for below use case

  I have to update entity on parent table, for which I have to use 'only' keyword before table name (select, update, delete,.. but not for insert, rename...).

  Is it possible to append 'only' keyword when updated via merge/update/save operation using DAO?

e.g., 

         Employee emp = empolyeeDao.findOne(1);

         emp.setName('Tom');

         empolyeeDao.update(emp);

          ....

and update is defined in generic DAO as :

    public T update( final T entity ){

        return this.entityManager.merge( entity );

    }

Here hibernate will generate update query without 'only' e.g., : update employee set name ='Tom', title='Mr' where id=1; but I need it to be update only employee set name ='Tom', title='Mr' where id=1;

using DAO. Is it possible?
