Question

我试图将这两个表中的数据导入到这样的导入中：

SELECT * INTO Complaints FROM( 
    SELECT *
    FROM Received2017 
UNION ALL
    SELECT *
    FROM Resolved2017
)

但是，我无法区分这些数据。所以理想情况下我想要一个专栏来说＆＃34;输入＆＃34;我可以标记它是收到还是解决，取决于它被拉出来的表格。

有没有这样做？

Answer 1

只需在你的联盟中添加一个常量列：

SELECT * INTO Complaints FROM( 
    SELECT *, "Received" As [Type]
    FROM Received2017 
UNION ALL
    SELECT *, "Resolved" As [Type]
    FROM Resolved2017
)

Answer 2

位于which列：

SELECT r.* INTO Complaints
FROM ((SELECT r.*, "received" as which
       FROM Received2017 as r
      ) UNION ALL
      (SELECT r.*, "resolved" as which
       FROM Resolved2017 as r
      )
     ) as r;

从源导入时的MS访问标记列
