Question

我的尝试：

UPDATE [DATA OUTPUT TABLE]
(
SELECT [DATA OUTPUT TABLE].[Journal Voucher ID], [DATA OUTPUT TABLE].[dBranch] AS Branch, [DATA OUTPUT TABLE].[dBranch] & " Shared Appropriation" AS [Shared Appropriation]

FROM [DATA OUTPUT TABLE]

WHERE [DATA OUTPUT TABLE].[Journal Voucher ID] In

  (
    SELECT [DATA OUTPUT TABLE].[Journal Voucher ID]
    FROM [DATA OUTPUT TABLE]
    GROUP BY [DATA OUTPUT TABLE].[Journal Voucher ID]
    HAVING
      (((First([DATA OUTPUT TABLE].dBranch)="Navy")
        AND
      (Last([DATA OUTPUT TABLE].dBranch)="USMC"))
      OR
      ((First([DATA OUTPUT TABLE].dBranch)="USMC")
        AND 
      (Last([DATA OUTPUT TABLE].dBranch)="Navy")))
  )
;) AS SATable
SET [DATA OUTPUT TABLE].[Shared Appropriation] = SATable.[Shared Appropriation]
Where [DATA OUTPUT TABLE].[Journal Voucher ID] = SATable.[Journal Voucher ID], [DATA OUTPUT TABLE].[dBranch] = SATable.[Branch];

我的目标是使用[dBranch]字段和＆＃34;的串联更新[DATA OUTPUT TABLE]中的[Shared Aropriation]列。共享拨款＆＃34;从我的查询（有效）：

SELECT [DATA OUTPUT TABLE].*
FROM [DATA OUTPUT TABLE]

WHERE ((([DATA OUTPUT TABLE].[Journal Voucher ID]) In (SELECT [DATA OUTPUT TABLE].[Journal Voucher ID]
FROM [DATA OUTPUT TABLE]
GROUP BY [DATA OUTPUT TABLE].[Journal Voucher ID]
HAVING (((First([DATA OUTPUT TABLE].dBranch))="Navy") AND ((Last([DATA OUTPUT TABLE].dBranch))="USMC")) OR (((First([DATA OUTPUT TABLE].dBranch))="USMC") AND ((Last([DATA OUTPUT TABLE].dBranch))="Navy"));)));

我的想法是为工作查询创建一个别名SATable，并将其抛入更新查询。

您的查询可以重写为：

UPDATE [DATA OUTPUT TABLE]
SET [DATA OUTPUT TABLE].[Shared Appropriation] = [dBranch] & " Shared Appropriation"
Where [DATA OUTPUT TABLE].[Journal Voucher ID] IN
  (
    SELECT [DATA OUTPUT TABLE].[Journal Voucher ID]
    FROM [DATA OUTPUT TABLE]
    GROUP BY [DATA OUTPUT TABLE].[Journal Voucher ID]
    HAVING
      (((First([DATA OUTPUT TABLE].dBranch)="Navy")
        AND
      (Last([DATA OUTPUT TABLE].dBranch)="USMC"))
      OR
      ((First([DATA OUTPUT TABLE].dBranch)="USMC")
        AND 
      (Last([DATA OUTPUT TABLE].dBranch)="Navy")))
  )

使用子查询访问更新查询
