Access查詢比較兩個表

Question

我有兩個表在Access中，表A和表B：

表MasterLockInsNew：

+----+-------+----------+ 
| ID | Value | Date | 
+----+-------+----------+ 
| 1 | 123 | 12/02/13 | 
| 2 | 1231 | 11/02/13 | 
| 4 | 1265 | 16/02/13 | 
+----+-------+----------+ 

表InitialPolData：

+----+-------+----------+---+ 
| ID | Value | Date |Type 
+----+-------+----------+---+ 
| 1 | 123 | 12/02/13 | x | 
| 2 | 1231 | 11/02/13 | x |  
| 3 | 1238 | 10/02/13 | y |  
| 4 | 1265 | 16/02/13 | a |  
| 7 | 7649 | 18/02/13 | z |  
+----+-------+----------+---+ 

所有我想要的是行來自表B，ID不包含在A中。我目前的代碼如下所示：

SELECT Distinct InitialPolData.* 
FROM InitialPolData 
WHERE InitialPolData.ID NOT IN (SELECT Distinct InitialPolData.ID 
           from InitialPolData INNER JOIN 
            MasterLockInsNew 
            ON InitialPolData.ID=MasterLockInsNew.ID); 

但是，只要我在Access中運行它，它會崩潰！表格相當大，但我不認爲這是原因。

任何人都可以幫忙嗎？

謝謝

Answer 1

，或者嘗試使用left outer join：

SELECT b.* 
FROM InitialPolData b left outer join 
MasterLockInsNew a on 
b.id = a.id 
where 
a.id is null 

Answer 2

簡單的子查詢會做。

select * from InitialPolData 
where id not in (
    select id from MasterLockInsNew 
); 

Answer 3

嘗試使用NOT EXISTS：

SELECT Distinct i.* 
FROM InitialPolData AS i 
WHERE NOT EXISTS (SELECT 1 
        FROM MasterLockInsNew AS m 
        WHERE m.ID = i.ID)
