Hibernate many to one not updating is dating an unbeliever sin

In the past we have learned about database relationships, specifically the One-to-Many as well as the Many-to-Many and One-to-One and that was all good, great and grand…But now I want to talk about how to create those same relationships inside of Hibernate.They are automatically persisted when referenced by a persistent object and are automatically deleted when unreferenced.If a collection is passed from one persistent object to another, its elements might be moved from one table to another.I have seen many answers to this question but for some reason non of them work for me.

An object in a collection might be handled with "value" semantics (its life cycle fully depends on the collection owner), or it might be a reference to another entity with its own life cycle.I would advice you to not use Join Column in that way.JPA is an OBJECT relational mapping framework so the data model should be object based and not be bound to the relational data model.I am working on a legacy code base with an existing DB schema.The existing code uses SQL and PL/SQL to execute queries on the DB.
