An example of an AI chatbot conversation about advanced queries in Spring Boot Data JPA.
How can I optimize my Spring Boot Data JPA queries?
You can optimize your queries by using pagination, projections, and custom queries with the @Query annotation.
What are projections in Spring Data JPA?
Projections allow you to fetch only the necessary fields from your entities, reducing the amount of data retrieved.
Can you give me an example of a custom query?
Sure! You can use the @Query annotation like this: @Query("SELECT u FROM User u WHERE u.age > ?1") to fetch users older than a certain age.
How do I implement pagination in my queries?
You can implement pagination by using the Pageable interface in your repository methods, like findAll(Pageable pageable).
