SQL Server 2012中無界的以下工作方式如何工作？

Question

The Table "Cric_Team" looks like this

當我在SQL Server 2012中執行以下查詢時，'無界跟隨'不計算直到該分區的最後一行的總和。但是，根據定義，它應該計算到當前行的最後一行。

SELECT Cric_Id，Cric_First_Name，Cric_Last_Name，Cric_Role，運行，幾個世紀以來，第五十AS五十年代，鴨，SUM（鴨子）OVER（PARTITION BY Cric_Role ORDER BY鴨子電流範圍內行和無限的以下兩項）AS Total_Ducks FROM Cric_Team

如何使用降序排序呢？這是做你想做的嗎？

SELECT Cric_Id, Cric_First_Name, Cric_Last_Name, Cric_Role, Runs, 
     Centuries, Fifty AS Fifties, Ducks, 
     SUM(Ducks) OVER (PARTITION BY Cric_Role ORDER BY Ducks DESC) AS Total_Ducks 
FROM Cric_Team;
