排序後的排序/組結果

Question

我有SQL查詢，我正在嘗試命令排序後顯示的結果。

這適用於從一個存儲位置（SLOC）到另一個存儲位置（SLOC）的情況（UNIQSN）。我試圖按照時間順序獲取存儲位置之間的行程歷史記錄。

「代碼」勝過千言萬語！

我想下面的查詢：

SELECT 
    uniqsn, 
    SLOC, 
    Update_DATETIME, 
    RANK() OVER (PARTITION BY SLOC ORDER BY Update_DATETIME) RANKING 
FROM TABLE 

我找

相反，我想實現下面的結果。誰可以幫忙？

謝謝！

Answer 1

你有缺口和孤島問題。此外，你想按照最早的日期排序（從我所知道的情況）。

爲此：

select t.*, dense_rank() over (partition by uniqsqn order by min_ud) as ranking    
from (select t.*, 
      min(update_datetime) over (partition by uniqsqn, sloc, seqnum - seqnum_us) as min_ud 
     from (select t.*, 
        row_number() over (partition by unisqn order by update_datetime) as seqnum, 
        row_number() over (partition by uniqsqn, sloc order by update_datetime) as seqnum_us 
      from t 
      ) t 
    ) t;
