如何在MS-Access中創建一個返回三個其他查詢的交集的查詢？

Question

我有一個“搜索”表單，允許用戶輸入位置，日期或ID。 此表單生成三個查詢，返回適當的結果，如果沒有為該類別輸入搜索詞，則生成所有記錄。 我打算做第四個查詢，它采用前三個的交集，但一直無法使它工作。 我已經回顧了有關使用SQL INNER JOIN函數的類似問題，但無法使其工作。 我的三個查詢中的每個查詢都在下面。 （或者，如果有更好的方法可以做到這一點，請告訴我。我嘗試在一個查詢中完成所有操作，這很糟糕）。

Qry_ByDate：

SELECT tbl_AssyMoves.[Assy ID], tbl_AssyMoves.[From ICA], tbl_AssyMoves.[From Loc], tbl_AssyMoves.[To ICA], tbl_AssyMoves.[To Loc], tbl_AssyMoves.Date, tbl_AssyMoves.Comments
FROM tbl_AssyMoves
WHERE (((tbl_AssyMoves.Date) Between [Forms]![Form1]![StartDate] And [Forms]![Form1]![EndDate]))

Qry_ByLoc：

SELECT tbl_AssyMoves.[Assy ID], tbl_AssyMoves.[From ICA], tbl_AssyMoves.[From Loc], tbl_AssyMoves.[To ICA], tbl_AssyMoves.[To Loc], tbl_AssyMoves.Date, tbl_AssyMoves.Comments
FROM tbl_AssyMoves
WHERE (((tbl_AssyMoves.[From ICA]) Like Forms!Form1!Combo_ICA) And ((tbl_AssyMoves.[From Loc]) Like Forms!Form1!Txt_Loc)) Or (((tbl_AssyMoves.[To ICA]) Like Forms!Form1!Combo_ICA) And ((tbl_AssyMoves.[To Loc]) Like Forms!Form1!Txt_Loc))

Qry_ByID：

SELECT tbl_AssyMoves.[Assy ID], tbl_AssyMoves.[From ICA], tbl_AssyMoves.[From Loc], tbl_AssyMoves.[To ICA], tbl_AssyMoves.[To Loc], tbl_AssyMoves.Date, tbl_AssyMoves.Comments
FROM tbl_AssyMoves
WHERE (((tbl_AssyMoves.[Assy ID]) Like [Forms]![Form1]![txt_AssyID]))

Answer 1

您需要使用UNION語句來組合三個查詢的結果。 在Access中， UNION自動不會返回重復項，這可能是您想要的。 如果你想要重復，你可以使用UNION ALL

SELECT tbl_AssyMoves.[Assy ID], tbl_AssyMoves.[From ICA], tbl_AssyMoves.[From Loc], 
tbl_AssyMoves.[To ICA], tbl_AssyMoves.[To Loc], tbl_AssyMoves.Date, tbl_AssyMoves.Comments

FROM 

(SELECT tbl_AssyMoves.[Assy ID], tbl_AssyMoves.[From ICA], tbl_AssyMoves.[From Loc], 
tbl_AssyMoves.[To ICA], tbl_AssyMoves.[To Loc], tbl_AssyMoves.Date, tbl_AssyMoves.Comments 
FROM Qry_ByDate

UNION SELECT tbl_AssyMoves.[Assy ID], tbl_AssyMoves.[From ICA], tbl_AssyMoves.[From Loc], 
tbl_AssyMoves.[To ICA], tbl_AssyMoves.[To Loc], tbl_AssyMoves.Date, tbl_AssyMoves.Comments 
FROM Qry_ByLoc

UNION SELECT tbl_AssyMoves.[Assy ID], tbl_AssyMoves.[From ICA], tbl_AssyMoves.[From Loc], 
tbl_AssyMoves.[To ICA], tbl_AssyMoves.[To Loc], tbl_AssyMoves.Date, tbl_AssyMoves.Comments 
FROM Qry_ById)

Answer 2

3個查詢的交集返回應用WHERE子句中所有條件的所有行：

SELECT tbl_AssyMoves.[Assy ID], tbl_AssyMoves.[From ICA], tbl_AssyMoves.[From Loc],
tbl_AssyMoves.[To ICA], tbl_AssyMoves.[To Loc], tbl_AssyMoves.Date, tbl_AssyMoves.Comments
FROM tbl_AssyMoves 
WHERE
  (tbl_AssyMoves.Date Between [Forms]![Form1]![StartDate] And [Forms]![Form1]![EndDate])
  And
  (tbl_AssyMoves.[Assy ID]) Like [Forms]![Form1]![txt_AssyID])
  And
  (((tbl_AssyMoves.[From ICA]) Like Forms!Form1!Combo_ICA) And ((tbl_AssyMoves.[From Loc]) Like Forms!Form1!Txt_Loc)) Or (((tbl_AssyMoves.[To ICA]) Like Forms!Form1!Combo_ICA) And ((tbl_AssyMoves.[To Loc]) Like Forms!Form1!Txt_Loc))
