需要MS Access查询[保留]

Question

我在“ customer ”表中有数据，例如

ID    NAME    CITY
11    John     A
12    Peter    B
13    Robin    A
14    Steve    C
15    Methew   D
16    Matt     C
17    Nancy    C
18    Oliver   D

我希望查询仅显示同一城市中每2个客户的数据。

输出应该是

ID    NAME    CITY
11    John     A
13    Robin    A
15    Methew   D
18    Oliver   D

              FROM Customers
           GROUP BY  City 
          HAVING count(*)=2) as b
where a.city=b.city

尝试这个

select * from Customer where City IN (
 select  city  from Customer as c
  group by city having Count(City) = 2)

请尝试此查询，如果您有任何问题，请告诉我们。

FROM Customer AS a
INNER JOIN Customer AS b ON a.City = b.City

Answer 4

我不知道如何在这里以表格形式写入数据。 如果有人，请以表格格式编辑数据。 ID NAME和CITY是标题。 A，B，C，D是城市名称。 11，12，13，14，14，15，16，17，18是ID
