Is it possible to integrate native SQL queries when working with Spring Data JPA?

Yes, in Spring Data JPA, you can use native SQL queries. To do this, you can declare a method in the repository with the @Query annotation, specifying the parameter nativeQuery = true.

Example:

public interface UserRepository extends JpaRepository<User, Long> {
    @Query(value = "SELECT * FROM users WHERE email = ?1", nativeQuery = true)
    User findByEmailNative(String email);
}

Thus, you can execute any SQL queries if the standard JPA methods are insufficient or if optimization is needed.
