Hi all, I am new user of hibernate, and getting confused with the working of save Or Update().
There is a possibility that the following may work if dynamic-update has been enabled, but I am not 100% that there are no side-effects if things are more complicated than simple properties.
For example, I don't know what will happen with cascades to associations or collections.
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.
