Master Hibernate and JPA with Spring Boot in 100 Steps - Step 15 - Implementing findByID JPA Repository Method

The video tutorial explains how to create and manage a JPA repository in a Spring application. It covers transaction management, database connection using an entity manager, and the implementation of a 'find by ID' method. The tutorial also discusses configuring Spring Boot applications, handling errors, and the automatic schema update feature of Hibernate. Finally, it demonstrates how to enable SQL query logging to verify database operations.

What is the primary role of a repository in JPA?

• To handle transaction management

• To manage database connections

• To define database schemas

• To manage entities and perform CRUD operations

Why is transaction management important in database operations?

• To ensure all operations succeed or fail together

• To speed up database queries

• To automatically create database tables

• To reduce the size of the database

What is the role of the Entity Manager in JPA?

• To manage database connections

• To handle user authentication

• To serve as an interface to the persistence context

• To define database schemas

What is the purpose of renaming the application in the context of JPA?

• To enable automatic schema creation

• To enhance security

• To avoid conflicts with other components

• To improve application performance

What error might occur when running a JPA application if the table already exists?

• Table not found

• Database connection failed

• Table already exists

• Entity not defined

How does Spring Boot handle schema creation when using an in-memory database?

• It requires manual schema definition

• It automatically creates the schema

• It uses a third-party tool for schema creation

• It does not support schema creation

How can you enable SQL query logging in a JPA application?

• By setting spring.jpa.show-sql to true

• By enabling debug mode

• By configuring the database server

• By using a third-party logging tool
