sql分页查询要求:
用一条sql语句输出表UserInfo表中31到40记录(数据库为SQL Server,以自动增长的ID作为主键,注意ID可能不是连续的,分页查询)。
其实就是写分页查询:
每页条数:10条;
当前页码:4页;
分页代码:
复制代码 代码示例:
//第一种:
select * from
(select ROW_NUMBER() over(order by Id asc) as num,* from UserInfo)as u
where u.num
between
10*(4-1)+1
and
10*4
//第二种:
select top 10 * from UserInfo
where Id not in
(select top (10*3) id from UserInfo order by Id)
order by Id
