AppEngine에 JDO 쿼리 I AppEngine에 함께 일하고 있어요

Question

예상대로 작동하지 않습니다와 내가 함께 데이터 엔티티를 조회 할 :

• BOOL 데이터 '를 선택하면'False입니다.
• 'registrationTimestamp'날짜의 오름차순입니다.

내 코드 : 나는 datas를 볼 때

Query query = pm.newQuery(DeviceInfo.class); 
query.setFilter("optional == False"); 
query.setOrdering("registrationTimestamp asc"); 
List<DeviceInfo> datas = (List<DeviceInfo>)query.execute(); 

이 '선택'에 데이터가 있습니다은 True입니다. '선택 사항'이 True 인 항목을 필터링 아웃하려고합니다. setFilter ("optional == False")가 작동하지 않는 것 같습니다.

내가 원하는 쿼리를 어떻게 수행 할 수 있습니까?

optional = false 

일을해야하지만, 당신은 documentation

Query q = new Query("DeviceInfo") 
      .addFilter("optional", 
         Query.FilterOperator.EQUAL, 
         false); 

에 따라 적절하게 필터를 추가하는 것을 고려가
