我在 Jpql 中使用 @Query 注释，我用额外的 "distinct" 修改了我的查询，如何修复它？

Question

在我的存储库中，我用额外的 "distinct" 修改了我的查询，但它不起作用

@Query(value = "select distinct i from Item i " 
                  +"where i.store = ?1 and i.itemVariant IN ?2 "
                  +"and i.status = ?3 " )
Page<Item> findByStoreAndItemVariantInAndStatus
      (Store store, List<ItemVariant> itemVariant ,byte  status, Pageable pageable);

如果我删除额外的修改@Query，这有效但结果是重复的

我已经修好了。我使用本机查询更改它并将不同的更改为分组依据，并且有效

    @Query(value = "SELECT i.* " 
                  +"  FROM public.mst_item as i " 
                  +"  join public.mst_store as ist " 
                  +"  on i.store_id = ist.id " 
                  +"  join public.mst_item_classifiers as iv " 
                  +"  on iv.item_id = i.id " 
                  +"  where ist.id = :store and iv.name IN "
                  +"       (select ic.name from public.mst_item_classifiers as ic "
                  +"        where ic.name like concat('%',:itemVariant,'%') and ic.status = :status ) " 
                  +"  and i.status = :status "
                  +"  group by ?#{#pageable}, i.id",
                    nativeQuery = true)
 Page<Item> findByStoreAndItemVariantInAndStatus(@Param("store")Store store,@Param("itemVariant") String itemVariant , @Param("status") byte  status, Pageable pageable);
