Master Hibernate and JPA with Spring Boot in 100 Steps - Step 75 - Hibernate Tips - Hibernate Soft Deletes - @SQLDelete

The video tutorial provides tips on using Hibernate, focusing on implementing soft delete functionality. It begins by explaining hard delete and its limitations, then introduces soft delete, which retains data history by marking records as inactive. The tutorial demonstrates adding a Boolean column to track deletion status and modifying SQL queries to update this status. It also covers testing the implementation and resolving data retrieval issues. The video concludes with a summary and hints at future discussions on advanced soft delete topics.

What is the primary difference between a hard delete and a soft delete?

• A hard delete marks the row as inactive, while a soft delete removes it completely.

• A hard delete removes the row completely, while a soft delete marks it as inactive.

• A hard delete encrypts the row, while a soft delete archives it.

• A hard delete archives the row, while a soft delete encrypts it.

Why might you want to use a soft delete instead of a hard delete?

• To simplify database schema

• To improve query performance

• To maintain a history of data changes

• To save storage space

What type of column is added to implement a soft delete?

• Date

• Boolean

• String

• Integer

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

• To encrypt the data before deletion

• To update the deletion status instead of removing the row

• To archive the data after deletion

• To log the deletion operation

What happens when a row is soft deleted?

• The row is encrypted.

• The row is archived.

• The row is completely removed from the database.

• The is_deleted column is set to true.

How does the @Where annotation help in retrieving data?

• It logs the retrieval operation.

• It ensures only active rows are retrieved.

• It encrypts the data before retrieval.

• It archives inactive rows.

What does the @Where annotation add to the select queries?

• A condition to log queries

• A condition to archive data

• A condition to exclude inactive rows

• A condition to encrypt data
