Spring data JpaRepository pagination and group by

Question

In my JpaRepository interface I got the following method that works fine:

Page<PermissionRule> findByOrganizationIdAndTypeStringAndObjectReferenceIgnoreCaseContaining(
        Long organizationId, String typeId, String searchTerm, Pageable pageable);

What I need is the same query with a group by object_reference.

This is what I tried doing : EDIT

@Query(value = "SELECT object_reference, dst_type, other FROM permission_rule pr WHERE pr.organization_id = %?1% AND pr.dst_type_id = %?2% AND pr.object_reference LIKE %?3% GROUP BY object_reference", nativeQuery = true)
Page<PermissionRule> getFunds(Long organizationId, String dstTypeId, String searchTerm, Pageable pageable);

but I get the following error

InvalidJpaQueryMethodException: Cannot use native queries with dynamic sorting and/or pagination in method

Also if it helps my entity column that I want to use in GROUP BY is

@Column(name = "object_reference", nullable = false)
private String objectReference;

My question is whether there is an easier way to do it or I still need a custom query (do I need to move the custom query in the Entity maybe or use named query instead?) ?

Solution

Ignoring why I need to do a Group By without an aggregate, I found my solution:

@Query("SELECT pr FROM PermissionRule pr WHERE pr.organizationId = ?1 AND pr.type = ?2 GROUP BY objectReference")
Page<PermissionRule> getFunds(Long organizationId, String type, Pageable pageable);

Seems more straight forward than the native_query approach.

You probably need to use countQuery for pagination to work with native query.
