无限制的追随者如何在SQL Server 2012中工作？

Question

表“ Cric_Team”看起来像这样

当我在SQL Server 2012中执行以下查询时，“无限制跟随”未计算该分区的最后一行的总和。 但是，按照定义，它应该计算当前行的最后一行。

SELECT Cric_Id，Cric_First_Name，Cric_Last_Name，Cric_Role，Runs，Centuries，Fifty AS 50五十，鸭子，SUM（Ducks）

如何使用降序排序呢？ 这是您想要的吗？

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;
