Join (custom) query in Spring Data JPA
0
$begingroup$
I'm trying to make a REST service using Spring Boot and Spring Data. I have written a query using join and have achieved the required o/p but I'm curious to know if that is a right way of doing it or I can do it with a better approach. Here is the query using @Query annotation.
@Query("select b.bookId, b.bookName, a.authorId, a.authorName, b.language, "
+ "g.genreId, g.genreName,b.goodReadReviews from Book b, Author a, "
+ "Genre g where b.author=a.authorId and b.genre=g.genreId and "
+ "a.authorId=?1 and g.genreId=?2")
List<Object> findByAuthorIdAndGenreId(int authorId, int genreId);
