Question

我有一个包含一些记录的表，表示该表是Student，它有一个名为total_mark的列。现在我需要从total_mark列中获取总数第7位的学生的详细信息。如何在SQL SERVER 2008中执行此操作？

Answer 1

首先，定义你的意思＆＃34; 7th＆＃34;。 7岁？智商第7名？第7高？不管。

WITH
RankedStudents AS ( 
    SELECT *, ROW_NUMBER() OVER ( ORDER BY <Whatever> ) AS RowNumber FROM <Schema>.<Object>
)
SELECT * 
FROM RankedStudents 
WHERE RowNumber = 7 ;

Answer 2

首先选择前7位，然后反转排序，只取第一行：

SELECT TOP 1 * FROM (
    SELECT TOP 7 *
    FROM RankedStudents 
    ORDER BY total_mark desc) x
ORDER BY total_mark

Answer 3

试试这个

WITH CTE AS(
SELECT total_mark,RANK() OVER (ORDER BY total_mark DESC)AS RANKED FROM SN_DB)
SELECT DISTINCT * FROM CTE   WHERE RANKED = 7
