sql语句聚合等疑难问题收集

数据表中比如有20条数据
读取前5条数据
select top　5 * from 表 order by id desc
读取前5条数据后的5条数据
(就是查询前10条记录，取后面5个)
select top 5 * from 表 where 
id not in (select top 5 id from 表)

===================================================================================SELECT TOP 11 * FROM (         SELECT ROW_NUMBER() OVER (ORDER BY StuID) AS RowNumber, *         FROM StuInfo)   tWHERE RowNumber >= 10 假设StuID是StuInfo表的主键“学号”。先按学号排序，生成行号，再返回行号>=10时的前11条记录，即行号为10~20的11条记录。=======================================================================select top 10 * from [table_name] where id in (select top 20 id from [table_name] order by id desc) order by id asc这样显示出来的就是：从11到20条数据
