获取某一行数据

比如：

 

declare @t as table([datas] nvarchar(40))
insert into @t ([datas]) values(n'df'),(n'w4f'),(n'eyy'),(n'er'),(n'gff'),(n'a445')

select [datas] from @t order by [datas]

 

由于我们不清楚datas数据内容，它是动态的内容。但是我们需要获取这表中的某一笔记录，那如何获取呢？

可以使用row_number方法来求得：

 

select [datas] from (
    select row_number() over (order by [datas]) as [rownumber], [datas] from @t) as t
where [rownumber] in (2,5)
