18           11ty      114   12-21-12     1    6

我想要以下结果：

结果

No   name    quantity     date  att3 att4    x2     x3
-----------------------------------------------------------------------
1    Joe       100   12-12-12     5    6    att2  att3
1    Joe       200   12-13-12     8    1    att2  att3  
1    Joe       140   12-16-12     9    6    att2  att3
2    Jack       10   12-19-12     1    6    att2  att3
2    Jack       20   12-19-12     1    1    att2  att3
2    Jack      114   12-21-12     1    6    att2  att3

这样做我正在做

SELECT
  b.name, 
  a.quantity, 
  a.date, 
  a.att3,
  a.att4, 
  b.x2, 
  b.x3
FROM
  Deposit a INNER JOIN Customer b
  ON a.CustomerID = b.CustomerID;

如何为示例中的每个不同客户获取编号列计数器？

有没有更好的方法来显示这两个表之间的内连接？

Answer 1

你可以：

SELECT DCount("*","Customer","CustomerID <='" & b.CustomerID & "'") AS Ct, 
b.name, 
a.quantity, 
a.Date, 
a.att3, 
a.att4, 
b.x2, 
b.x3
FROM Deposit AS a 
INNER JOIN Customer AS b ON a.CustomerID = b.CustomerID
ORDER BY b.CustomerID;

结果：

Ct  name    quantity    Date    att3  att4  x2      x3
1   Jack    114     21/12/2012  1       6   att2    att3
1   Jack    20      19/12/2012  1       1   att2    att3
1   Jack    10      19/12/2012  1       6   att2    att3
2   Joe     140     16/12/2012  9       6   att2    att3
2   Joe     200     13/12/2012  8       1   att2    att3
2   Joe     100     12/12/2012  5       6   att2    att3
