我试图编写一个查找重复项的查询。该查询将查看最新的 2013 年订单日期，然后与最新的 2014 年订单匹配，以查找两个年份中都存在的记录。我的代码只给了我 2013 年的数据，而不是 2013 年和 2014 年的数据。所以我想显示这两年的重复数据。

例如下面是示例数据

Bill_Member_ID........Lname....................Order_Date  
123..........................Smith...............01/05/2013  
123..........................Smith...............02/15/2014  
123..........................Smith...............02/18/2014  
456..........................Jones...............01/07/2013  
789..........................Brown...............01/05/2013  
789..........................Brown...............02/17/2014  
789..........................Brown...............03/17/2014
992..........................White...............03/15/2013
992..........................White...............01/05/2014

那么我应该得到一个回报 

Bill_Member_ID........Lname....................Order_Date    
123..........................Smith...............01/05/2013  
123..........................Smith...............02/18/2014  
789..........................Brown...............01/05/2013  
789..........................Brown...............03/17/2014
992..........................White...............03/15/2013
992..........................White...............01/05/2014

这是我的代码

如果您在 SQL Server 中执行此操作，则可以使用窗口函数：

select s.*
from (select s.*,
             min(year(order_date) over (partition by Bill_Member_ID) as minyear,
             max(year(order_date) over (partition by Bill_Member_ID) as maxyear,
             row_number() over (partition by Bill_Member_ID, year(order_date) order by order_date desc) as seqnum
      from sample s
      where year(order_date) in (2013, 2014)
     ) s
where minyear <> maxyear and seqnum = 1;

子查询获取每个成员的最小和最大年份，并为每年的记录分配一个序号。

外部where验证有两年（where minyear = 2013 and maxyear = 2014如果你愿意，写起来会更明确）并从每年中选择一个记录。

我不确定sample与您拥有的表格有什么关系。您可以轻松地使用子查询或 CTE 来定义它。

您还可以尝试临时表或 CTE 比较。

忽略您的查询并专注于您的样本集以简化一点，您可以使用 withROW_NUMBER()和 a COUNT()with几个步骤获得所需的输出OVER()：

;with cte AS (SELECT *,ROW_NUMBER() OVER(PARTITION BY Bill_Member_ID,YEAR(Order_Date) ORDER BY Order_Date DESC) AS RN
              FROM YourTable
              WHERE YEAR(Order_Date) IN (2013,2014)
             )
     ,cte2 AS (SELECT *,COUNT() OVER(PARTITION BY Bill_Member_ID) AS Yr_CT
               FROM cte
               WHERE RN = 1
              )
SELECT Bill_Member_ID,Lname,Order_Date 
FROM cte2
WHERE Yr_CT > 1
ORDER BY Bill_Member_ID,Order_Date

该ROW_NUMBER()函数为每条记录添加一个数字，从PARTITION BY（可选）中定义的每个组开始，并根据ORDER BY（必需）排序。

添加OVER()到COUNT()允许您通过分组获得计数，而不会像使用GROUP BY.

因此，第一个cte添加了一个有用的数字，可用于过滤到Order_Date每个 每年的最新Bill_Memmber_ID数据，第二个添加一个计数每个有多少年Bill_Member_ID的记录。

更新：我最初并没有考虑将其限制为 2 年，而是将任何多年的情况视为所需的输出。因此，鉴于只有 2 年的要求，Gordon 的方法更简单，如果您需要考虑某人在其他几年内有订单的地方，您可以使用这个答案。
