Have you manually created queries when working with Spring Data?

Yes, in Spring Data it is often necessary to create queries manually, especially when the standard repository methods are insufficient. You can use the @Query annotation on a repository interface method, where you specify a JPQL or native SQL query.

Example:

public interface UserRepository extends JpaRepository<User, Long> {
    @Query("SELECT u FROM User u WHERE u.status = ?1")
    List<User> findByStatus(String status);
}

You can also use native queries:

@Query(value = "SELECT * FROM users WHERE status = ?1", nativeQuery = true)
List<User> findByStatusNative(String status);

This allows flexible query formation beyond the standard Spring Data methods.
