Hibernate 5.4: How to manage cascading deletes with @OneToMany when using a custom delete query?
I've been working on this all day and I'm building a feature where I'm collaborating on a project where I'm trying to figure out I'm currently working with Hibernate 5.4 and have a scenario where I need to delete a parent entity that has a collection of child entities mapped with a `@OneToMany` relationship... I've set the `cascade` option to `CascadeType.ALL`, but I'm running into issues when attempting to execute a custom delete query on the parent entity. I expect the child entities to be deleted as well, but they remain in the database after the parent is deleted. Here’s the relevant part of my entity configuration: ```java @Entity public class Parent { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; @OneToMany(mappedBy = "parent", cascade = CascadeType.ALL) private List<Child> children; // Getters and Setters } @Entity public class Child { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; @ManyToOne @JoinColumn(name = "parent_id", nullable = false) private Parent parent; // Getters and Setters } ``` When I execute the delete query like this: ```java Session session = sessionFactory.openSession(); Transaction tx = session.beginTransaction(); String hql = "DELETE FROM Parent p WHERE p.id = :parentId"; Query query = session.createQuery(hql); query.setParameter("parentId", parentId); query.executeUpdate(); tx.commit(); session.close(); ``` The parent entity gets deleted, but the associated children remain in the database instead of being deleted as well. I've also tried using `session.remove(parent)` after loading the parent, but that still doesn't cascade the delete to the children, possibly due to the custom query bypassing the Hibernate session's lifecycle management. How can I ensure that deleting the parent entity also deletes all associated child entities when using a custom delete query? Is there a recommended approach for this situation without losing the benefits of cascading operations? My team is using Java for this application. Is this even possible? Thanks for any help you can provide!
