Aceess Query - 필드가 null이면 출력되지 않습니까?

Question

나는 액세스 쿼리 (2003)가 :

SELECT [User] [100], [101], [102], [103], [104], [105], [106], [107], [108], [109], [110] 
FROM [Access_Count>1] 

I는 다음과 같이 얻을 결과 : I 출력에서 ​​빈 열/필드를 제외 할 수있는 방법이

[User], [100], [101], [102], [103], [104], [105], [106], [107], [108], [109], [110] 
UserA,100,101,,,,,,,,, 
UserB,,,,,,,,109,110 

거기를? 그래서 내 결과는 다음과 같이 될 것이다 : 나는 구글을 통해 오늘 대규모 사냥이 있었다

[User], [100], [101], [109], [110] 
UserA,100,101,, 
UserB,,,109,110 

, 비슷한 질문이 다른 질문 만 해결 결코 발견했다.

Answer 1

마이클 출력은 테이블을 할 필요가 있는가? 값을 문자열로 연결할 수 있습니까?

그렇다면, 당신은 다음과 같이 뭔가를 할 수 있습니다

select t.[user], 
     mid((iif(Keep100 = 'Y', ','&[100])& 
      iif(Keep101 = 'Y', ','&[101])& 
      . . . 
      ), 2) 
from [AccessCount>1], 
    (select t, iif(max([100]) is null, 'N', 'Y') as Keep100, 
      iif(max([101]) is null, 'N', 'Y') as Keep101, 
      . . . 
     from [AccessCount>1] 
    ) tkeep 

아이디어는 구분 기호로 쉼표로 문자열을 구축하는 것입니다. mid 문은 문자열의 첫 번째 문자를 제거합니다.

Answer 2

나는, 그것은 # 오류로 액세스 열을 던지고 나는 고든 리노 프에 대한 모든 200

큰 감사를 수행하려고 할 때이 쿼리로 분리해서했고, 나는 이것이 미래에 누군가가 도움이되기를 바랍니다 :)
