我有一张桌子：
ID | 杀戮 | 死亡人数
$ratio = $kills / $deaths;

如何对字段进行排序，以便以最高比率回显 ID？

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

你试过这个：

select id from table order by kills/deaths desc limit 1;

(kills + 0.0)/deaths如果它没有自动提升为浮动，请尝试。

还要尽量kills/(deaths+0.0001)防止被零除..

尝试

SELECT TOP 1 ID, cast(Kills/Deaths as float) FROM KillsDeaths
ORDER BY (Kills/Deaths) DESC
