Question

我在Microsoft Access 2013中有两个表：

tblService

PART_ID  SERV_DATE   SERV_REMARK  
A0001    11/1/2013   GOOD#1  
A0001    11/13/2013  GOOD#2  
A0001    11/25/2013  GOOD#3

tblWithdraw

PART_ID DRAWN_DATE  DRAWN_REASON  DRAWN_TO  
A0001   11/6/2013   PM            OW601  
A0001   11/20/2013  120 PM        OW603  
A0001   11/30/2013  REPLACEMENT   OW605

这是我想要的结果：

PART_ID SERV_DATE   SERV_REMARK  DRAWN_DATE  DRAWN_REASON  DRAWN_TO  
A0001   11/1/2013   GOOD#1       11/6/2013   PM            OW601  
A0001   11/13/2013  GOOD#2       11/20/2013  120 PM        OW603  
A0001   11/25/2013  GOOD#3       11/30/2013  REPLACEMENT   OW605

但我无法使用INNER JOIN，RIGHT JOIN或LEFT JOIN获得结果。我尝试使用FULL JOIN，但系统提示我错误：

FROM子句中的语法错误

以下是我的SQL。

SELECT 
  S.PART_ID, SERV_DATE, 
  SERV_REMARK, DRAWN_DATE, 
  DRAWN_REASON, DRAWN_TO
FROM 
  tblService AS S 
RIGHT JOIN 
  tblWithdraw AS W 
ON 
  S.PART_ID=W.PART_ID;

将结果显示为：

PART_ID SERV_DATE   SERV_REMARK  DRAWN_DATE  DRAWN_REASON  DRAWN_TO  
 A0001  11/1/2013     GOOD#1     11/6/2013        PM         OW601  
 A0001  11/13/2013    GOOD#2     11/6/2013        PM         OW601  
 A0001  11/25/2013    GOOD#3     11/6/2013        PM         OW601
 A0001  11/1/2013     GOOD#1     11/20/2013     120 PM       OW603  
 A0001  11/13/2013    GOOD#2     11/20/2013     120 PM       OW603  
 A0001  11/25/2013    GOOD#3     11/20/2013     120 PM       OW603
 A0001  11/1/2013     GOOD#1     11/30/2013  REPLACEMENT     OW605  
 A0001  11/13/2013    GOOD#2     11/30/2013  REPLACEMENT     OW605  
 A0001  11/25/2013    GOOD#3     11/30/2013  REPLACEMENT     OW605

有人可以更正我的SQL吗？或任何正确代码的链接？ THX！

Answer 1

您的两张桌子之间没有独特的关系，而您需要一张。例如，您必须重新构建表格（以及如何输入数据），以便它们具有一个值，使某个部分的每个实例与其他具有相同PART_ID的个体实例相同。

例如：

UID  PART_ID  SERV_DATE   SERV_REMARK  
1    A0001    11/1/2013   GOOD#1  
2    A0001    11/13/2013  GOOD#2  
3    A0001    11/25/2013  GOOD#3

UID  PART_ID  DRAWN_DATE  DRAWN_REASON  DRAWN_TO  
1    A0001    11/6/2013   PM            OW601  
2    A0001    11/20/2013  120 PM        OW603  
3    A0001    11/30/2013  REPLACEMENT   OW605

然后您可以将SQL修改为：

SELECT 
  S.PART_ID, SERV_DATE, 
  SERV_REMARK, DRAWN_DATE, 
  DRAWN_REASON, DRAWN_TO
FROM 
  tblService AS S 
RIGHT JOIN 
  tblWithdraw AS W 
ON 
  S.UID=W.UID;

这将给出您正在寻找的结果。
