SQl服務器表中的重複記錄不同年

Question

我試圖編寫查找重複的查詢。該查詢將查看最新的2013年訂單日期，然後匹配最新的2014年訂單，以查找在這兩年中存在的記錄。我的代碼只給了我2013年的數據，而不是2013年和2014年。所以我想顯示這兩年的重複。

例如下面是樣本數據

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 

於是我應該得到的

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 

這裏一回是我的代碼

Answer 1

忽視查詢並專注於您的樣本集簡化了一點，您可以使用ROW_NUMBER()的幾個步驟獲得您想要的輸出，以及一個COUNT()與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 

的ROW_NUMBER()功能增加了一些給每個記錄，根據ORDER BY從1開始每在PARTITION BY（可選）定義和有序組（必需）。

將OVER()添加到COUNT()可讓您通過分組獲得計數，而不會像在GROUP BY中那樣丟失詳細信息。

所以第一cte增加了大量用於過濾的最新Order_Date每年爲每個Bill_Memmber_ID有用，第二增加了多少年每個Bill_Member_ID有記錄的計數

更新：我起初並不考慮將其限制爲2年，並將任何多年的情況視爲預期產出。因此，考慮到只有2年的要求，Gordon的方法更簡單了，如果您需要考慮某人在其他幾年內的訂單可以使用此答案。

Answer 2

如果您在SQL Server這樣做，那麼你可以使用窗口功能：

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; 

提交查詢每個成員的最小和最大的一年，以及分配在一個序列號，記錄每年。

外部where驗證有兩年（如果您願意，可以更明確地寫入where minyear = 2013 and maxyear = 2014）並從每年中選擇一條記錄。

我不確定sample如何與您擁有的表格相關聯。您可以隨時使用子查詢或CTE來定義它。

Answer 3

select s1.id, s1.name, s1.orderDate as [date 2013], s2.orderDate as [date 2014] 
from 
( select id, name, max(orderDate) as [orderDate] 
    from cusOrder 
    where DatePart(yy, orderDate) = '2013' 
    group by id, name) as s1 
join 
( select id, name, max(orderDate) as [orderDate] 
    from cusOrder 
    where DatePart(yy, orderDate) = '2014' 
    group by id, name) as s2 
on s1.id = s2.id 

Answer 4

您也可以嘗試臨時表或CTE比較。
