Hibernate Inverse attribute

Question

I am creating a one-to-many relationship. so, i have a parent and a child. The cascade attribute is set to all.

I was wondering, if we consider the following piece of co

Answer 1

Case inverse = false:

In this case, it is parent's responsibility to save-update child and its relationship. So in your example, child will be updated in database. There will be two sql queries: 1) Insert child. 2) Update child with foreign key of parent id.

Case Inverse = true:

In this case , it is child's responsibility to save-update itself. So in your code, child will be saved in database but foreign key of parent will be null. Only one sql query will be executed and that is of insert child. For updating parent's foreign key, you need to manually save child.

Child child = new Child();
child.setParent(parent);
session.save(child);

I think, answer of these cases explains answer of your third question.

Hope this help.
