最高数量的"杀戮除以死亡"的SQL顺序

Question

我有一张桌子:
ID | KILLS | DEATHS
$ratio = $kills / $deaths;

如何订购字段,以便以最高比率回显ID？

Answer 1

WITH CTE AS
(
   SELECT T.*,
       Ratio = kills / deaths, 
       Rank = DENSE_RANK()OVER(PARTITION BY Id ORDER BY kills / deaths DESC) 
   FROM dbo.TableName T
)
SELECT * FROM CTE WHERE Rank = 1
