Likewise, the Entity Manager removes the relational data when you request that an entity be deleted.When I was making some changes into user details using simple code as shown bellow, it was updating record into user_details table. Hibernate Session Factory()Current Session(); session.begin Transaction(); User u=(User) session.load(User.class,new Long(2)); User Details details=User Details(); User Dao user Dao=new User Dao(); Address1("9999999999"); session.merge(u); Transaction().commit(); But, when I was using the same code to update the user details with the data getting from user's request ,it was not working as my expectation.It was inserting new record for userdetails into User_deatils table instead of Updating.
