Access 2010에서 다른 쿼리를 사용하여 쿼리를 삭제하십시오.

Question

레코드를 삭제하는 데 문제가 있습니다. 내 기본 키 Asset_ID라는 필드를 사용하여 두 테이블을 연결했습니다. 나는 일치하지 않는 모든 레코드를 가져 오는 쿼리를 생성하므로 일치하지 않는 레코드는 삭제하려고합니다. 내가 쿼리를 실행하면 "지정된 테이블에서 삭제할 수 없습니다"라는 오류 메시지가 표시되고 일부 조사가 수행되었으며 삭제 쿼리 속성으로 이동하여 "고유 레코드"옵션을 "예"로 변경하도록 제안했습니다. 일하지 않았어. 이걸 도와주세요.

DELETE DISTINCTROW [HANDHELD TABLE1 Without Matching HANDHELD TABLE].ASSET_ID 
FROM [HANDHELD TABLE1 Without Matching HANDHELD TABLE] 
WHERE ((([HANDHELD TABLE1 Without Matching HANDHELD TABLE].ASSET_ID) Is Not Null)); 

여기 핸드 헬드 TABLE SQL을 일치하지 않고 내 핸드 헬드 TABLE1입니다 : 여기 그것을 할 액세스 2010 쿼리 빌더를 사용하지만,하고

Answer 1

검사 플러시가 null 인 필드를 찾으려면 제공된 쿼리 에서처럼 테이블을 연결해야합니다.

그러면 문제는 키 필드 "ASSSET_ID"에 가입하고 null을 찾습니다. 이 사건은 핵심 분야로서 결코 일어나지 않을 것입니다.

DELETE DISTINCTROW [HANDHELD TABLE_1].INSPECTION_FLUSH, [HANDHELD TABLE].* 
FROM [HANDHELD TABLE] LEFT JOIN [HANDHELD TABLE] AS [HANDHELD TABLE_1] ON [HANDHELD TABLE].INSPECTION_FLUSH = [HANDHELD TABLE_1].INSPECTION_FLUSH 
WHERE ((([HANDHELD TABLE_1].INSPECTION_FLUSH) Is Null));
