Master Hibernate and JPA with Spring Boot in 100 Steps - Step 76 - Hibernate Soft Deletes - Part 2

The video tutorial covers the implementation and caveats of using soft delete in SQL, focusing on native queries and their limitations with annotations. It explains how Hibernate handles entity deletion and the importance of updating the cache. The tutorial introduces the pre remove hook to ensure the 'is deleted' attribute is updated correctly. Testing and logging are also discussed to verify the implementation.

What is a key limitation of using native queries with the @Where annotation in Hibernate?

• Native queries automatically apply the @Where annotation.

• Native queries are faster than JPQL queries.

• Native queries require manual addition of the 'is_deleted' condition.

• Native queries do not support SQL operations.

Why does Hibernate not update the entity cache when a native query is executed?

• Hibernate is unaware of changes made in native queries.

• Native queries automatically update the cache.

• Native queries do not trigger entity lifecycle events.

• Hibernate does not support native queries.

What is a potential risk of manually setting the 'is_deleted' attribute in the entity manager?

• It may lead to data inconsistency.

• It prevents the entity from being deleted.

• It triggers an error in the application.

• It automatically updates the database.

What is the purpose of the @PreRemove annotation in Hibernate?

• To update the 'is_deleted' attribute before an entity is removed.

• To log the removal of an entity.

• To automatically delete an entity from the database.

• To prevent an entity from being removed.

How does the @PreRemove annotation help in maintaining the entity state?

• It prevents the entity from being deleted.

• It automatically updates the database schema.

• It ensures the 'is_deleted' attribute is set to true.

• It logs the deletion process.

What is the role of logging in the implementation of the @PreRemove solution?

• To automatically update the entity state.

• To verify that the @PreRemove hook is triggered.

• To enhance the performance of the application.

• To prevent errors during deletion.

What is the main focus of the final section of the tutorial?

• Discussing the limitations of native queries.

• Exploring advanced Hibernate features.

• Testing and verifying the @PreRemove hook.

• Implementing a new database schema.
