What is the method in Hibernate for deleting data?
Hibernate offers several techniques for deleting data.
- To delete data using the delete method of an entity object: simply retrieve the entity object and then call the delete method. For example: session.delete(entity).
- Use JPQL (Java Persistence Query Language) delete statement: To delete data by creating a JPQL delete statement. For example: entityManager.createQuery(“DELETE FROM EntityName WHERE condition”).executeUpdate().
- Utilize the DELETE statement in HQL (Hibernate Query Language) to delete data. For example, you can create a DELETE statement in HQL like this: session.createQuery(“DELETE FROM EntityName WHERE condition”).executeUpdate().
- In order to delete data, you can use the Criteria API by creating a Criteria instance, setting the deletion conditions, and using the delete method. For example: session.createCriteria(EntityName.class).add(Restrictions.eq(“property”, value)).delete().
These methods can be selected based on specific needs.
