Question

MSSQL 2008R2

假设我有两列，“名称”和“总计”

Name    Total
Team1   2556.54
Team2   2204.77
Team3   2141.64
Team4   1401.37
Team5   1220.77
Team6   1149.92
Team7   1130.62
Team8   1073.69
Team9   1059.66
Team10  1028.52
Team11  970.02
Team12  947.85
Team13  886.93
Team14  788.09
Team15  730.99

是否可以从总列中计算和识别属于TOP 10％，BOTTOM 15％的行？

其中10％和15％是变量。

如果是这样的话？

提前谢谢。

Answer 1

--Top 10%
SELECT TOP (@top) PERCENT Name, Total
FROM Teams
ORDER BY Total DESC

--bottom 15%
SELECT TOP (@bottom) PERCENT Name, Total
FROM Teams
ORDER BY Total ASC

Answer 2

我道歉，但我忘了在问题中提到10％和15％是变量。

修改

似乎你把变量放在它起作用的括号中

SELECT top (@top)
