Hibernate merge not updating Webcam sextalk

The most important and frequently asked question in Hibernate is the difference between merge and update methods and often we can notice that developers use update() and merge() methods alternatively. We know that both merge() and update() methods are used to update the entity and can also change the state of an object(from detached to persistent state).

Using the select-before-update option will not help, since it is only used to confirm that at least a few values has been changed.Hi all, I am new user of hibernate, and getting confused with the working of save Or Update().I have read that save Or Update() will update the table entry if there is a record present for that ID, and if the id is not present then it simply insert the record. I have a Role Table like Role_id | Role_Name | Create_Time | Create_User | Update_Time | Update_USer1 Admin At null nullnow when from the UI when an update is happen, I just use this, they are set to null.
