本文介绍两种在SQL中选取特定区间数据的方法：一是利用分析函数row_number()结合partition by和order by进行精确排序；二是通过rownum虚列实现快速定位。这两种方法适用于不同场景，帮助开发者高效获取所需数据。

取100-150条数据的方法

1. 最佳选择：利用分析函数

row_number() over ( partition by col1 order by col2 )

比如想取出100-150条记录,按照tname排序

select tname,tabtype from (

select tname,tabtype,row_number() over ( order by tname ) rn from tab

) where rn between 100 and 150; 从第100条（包含第100条）到第150条数据，总共51条数据

2. 使用rownum 虚列

select tname,tabtype from (

select tname,tabtype,rownum rn from tab where rownum <= 150

) where rn >= 100;
