複数の結合が左にアクセス/サブクエリを結合します

Question

次のコードはMS Accessで正常に機能します。しかし、さらに左の結合を追加しようとしています。私の左の結合は、テーブルではなくクエリに参加します。

希望はこれが理にかなっています。

ご質問は明確ではないが、のMS Access + 追加LEFTはを登録しよう

SELECT 
    a.[business unit], 
    b.[Total Colleagues in DMS], 
    Sum(IIf([a].[Session Date] Is Not Null,1,0)) AS [Total Bookings], 
    Sum([a.Has Booking been cancelled (Yes/No)]) AS [Total Cancellations], 
    (Sum(IIf([a].[Session Date] Is Not Null,1,0))-Sum([a.Has Booking been cancelled (Yes/No)])) AS [Net Bookings], 
    Sum([a.lookup_attended]) AS Attended, 
    (b.[Total Colleagues in DMS]-(Sum(IIf([a].[Session Date] Is Not Null,1,0))-Sum([a.Has Booking been cancelled (Yes/No)]))) AS [Unbooked Spaces] 
FROM 
    everything AS a 
LEFT JOIN 
(
    SELECT 
     a.[business unit], count(*) AS [Total Colleagues in DMS] 
    FROM 
    (
     SELECT DISTINCT 
      a.lookup_id, 
      A.[BUSINESS UNIT] 
     FROM 
      EVERYTHING AS a 
     WHERE 
      (a.status<>"leaver" Or a.status<>"Not in scope") 
      And 
      A.PROJECT Is Null 
    ) AS [%$##@_Alias] 
    GROUP BY 
     a.[business unit] 
) AS b 
ON 
    a.[business unit] = b.[business unit] 
WHERE 
(
    ((a.status)<>"leaver" Or (a.status)<>"not in scope")  
GROUP BY 
    a.[business unit], 
    b.[Total Colleagues in DMS], 
    b.[business unit];

助けに感謝は私があなたの主な問題は、あなたが追加LEFTは、そのクエリに参加作られたということだと思いますあなたが上記に示していない、あなたが複数のJOINを持っている場合は、MS ACCESS SQLで必要とされるかっこでテーブルを囲まなかったことになります。それはあなたにエラーを与えました。

私が間違っている場合は、問題の内容をよりよく説明してください。

だから、これは仕事はないでしょう：

SELECT 
    a.[business unit], 
    b.[Total Colleagues in DMS], 
    Sum(IIf([a].[Session Date] Is Not Null,1,0)) AS [Total Bookings], 
    Sum([a.Has Booking been cancelled (Yes/No)]) AS [Total Cancellations], 
    (Sum(IIf([a].[Session Date] Is Not Null,1,0))-Sum([a.Has Booking been cancelled (Yes/No)])) AS [Net Bookings], 
    Sum([a.lookup_attended]) AS Attended, 
    (b.[Total Colleagues in DMS]-(Sum(IIf([a].[Session Date] Is Not Null,1,0))-Sum([a.Has Booking been cancelled (Yes/No)]))) AS [Unbooked Spaces] 
FROM 
    everything AS a 
LEFT JOIN 
(
    SELECT 
     a.[business unit], count(*) AS [Total Colleagues in DMS] 
    FROM 
    (
     SELECT DISTINCT 
      a.lookup_id, 
      A.[BUSINESS UNIT] 
     FROM 
      EVERYTHING AS a 
     WHERE 
      (a.status<>"leaver" Or a.status<>"Not in scope") 
      And 
      A.PROJECT Is Null 
    ) AS [%$##@_Alias] 
    GROUP BY 
     a.[business unit] 
) AS b 
ON 
    a.[business unit] = b.[business unit] 
LEFT JOIN your_query AS q ON q.whatever=a.whatever  

WHERE 
(
    ((a.status)<>"leaver" Or (a.status)<>"not in scope")  
GROUP BY 
    a.[business unit], 
    b.[Total Colleagues in DMS], 
    b.[business unit]; 

しかし、これは動作します：

SELECT 
    a.[business unit], 
    b.[Total Colleagues in DMS], 
    Sum(IIf([a].[Session Date] Is Not Null,1,0)) AS [Total Bookings], 
    Sum([a.Has Booking been cancelled (Yes/No)]) AS [Total Cancellations], 
    (Sum(IIf([a].[Session Date] Is Not Null,1,0))-Sum([a.Has Booking been cancelled (Yes/No)])) AS [Net Bookings], 
    Sum([a.lookup_attended]) AS Attended, 
    (b.[Total Colleagues in DMS]-(Sum(IIf([a].[Session Date] Is Not Null,1,0))-Sum([a.Has Booking been cancelled (Yes/No)]))) AS [Unbooked Spaces] 
FROM 
    ((everything AS a 
LEFT JOIN 
(
    SELECT 
     a.[business unit], count(*) AS [Total Colleagues in DMS] 
    FROM 
    (
     SELECT DISTINCT 
      a.lookup_id, 
      A.[BUSINESS UNIT] 
     FROM 
      EVERYTHING AS a 
     WHERE 
      (a.status<>"leaver" Or a.status<>"Not in scope") 
      And 
      A.PROJECT Is Null 
    ) AS [%$##@_Alias] 
    GROUP BY 
     a.[business unit] 
) AS b 
ON 
    a.[business unit] = b.[business unit]) 
LEFT JOIN your_query AS q ON q.whatever=a.whatever) 

WHERE 
(
    ((a.status)<>"leaver" Or (a.status)<>"not in scope")  
GROUP BY 
    a.[business unit], 
    b.[Total Colleagues in DMS], 
    b.[business unit]; 

お知らせをFROMと右括弧の後に左括弧
