對sql服務器中的排序數據進行排序

Question

***和***中的查詢將生成按status_date排序的分區行。現在，如果結果有多於一行的status_date，那麼我只想按change_date排序那些行。

我想出了下面的查詢，但它沒有給出想要的結果。

SELECT MID,status_date,status,change_date, row_number() OVER (PARTITION BY MID ORDER BY change_date DESC) as RN1, 1 as TimeRange 
        FROM 
         (
        *** SELECT MID,status_date,status,change_date, 
         rn = row_number() OVER (PARTITION BY MID ORDER BY status_date DESC) 
         FROM listing_History (nolock) 
         WHERE MID like '12-572561' **** 

         ) AS A 

對於參考：

內部***的從查詢結果和***：

12-572561 2012-06-11 00:00:00.000 Canceled 2012-06-11 14:53:22.957 1 
12-572561 2012-03-01 00:00:00.000 Canceled 2012-03-01 13:32:40.030 2 
12-572561 2012-01-02 00:00:00.000 Active  2012-01-02 07:32:34.067 3 
12-572561 2012-01-02 00:00:00.000 Active  2012-06-11 07:43:29.400 4 
12-572561 2012-01-02 00:00:00.000 Active  2012-01-10 00:01:03.407 5 
12-572561 2012-01-02 00:00:00.000 Active  2012-06-11 07:43:29.417 6 

與現有的查詢結果：

12-572561 2012-06-11 00:00:00.000 Canceled 2012-06-11 14:53:22.957 1 1 
12-572561 2012-01-02 00:00:00.000 Active  2012-06-11 07:43:29.417 2 1 
12-572561 2012-01-02 00:00:00.000 Active  2012-06-11 07:43:29.400 3 1 
12-572561 2012-03-01 00:00:00.000 Canceled 2012-03-01 13:32:40.030 4 1 
12-572561 2012-01-02 00:00:00.000 Active  2012-01-10 00:01:03.407 5 1 
12-572561 2012-01-02 00:00:00.000 Active  2012-01-02 07:32:34.067 6 1 

期望的結果：

12-572561 2012-06-11 00:00:00.000 Canceled 2012-06-11 14:53:22.957 1 1 
12-572561 2012-03-01 00:00:00.000 Canceled 2012-03-01 13:32:40.030 2 1

12-572561 2012-01-02 00:00:00.000 Active  2012-06-11 07:43:29.400 4 1 
12-572561 2012-01-02 00:00:00.000 Active  2012-01-10 00:01:03.407 5 1

Answer 1

您可以使用ORDER BY爲change_date在查詢

Answer 2

的ROW_NUMBER（）函數的結束並不確定訂單的結果。你需要一個ORDER BY子句。如果您不需要ROW_NUMBER（）值的結果，你可以做以下

SELECT MID,status_date,status,change_date 
FROM listing_History (nolock) 
WHERE MID like '12-572561' 
ORDER BY status_date DESC, change_date DESC
