Hibernate one to many association deletion

In a one to many bidirectional association with cascade enabled as all-delete-orphan in hibernate, is there any possibility ever hibernate try to delete child entity using foreign key column? Its firing one extra query delete from child where foreign_key_col = parent_primary_key.

Solution

  • For bidirectional relation,if you delete casacade in the parent entity.

    You can remove the child from parent directly.

    //set parent as null
child.setParent(null)

//parent.children.iterater and remove it from the iterator.

//then save the parent.
save(parent)
