本文为大家分享了SQL Server使用row_number分页的实现方法,供大家参考,具体内容如下

1、首先是

select ROW_NUMBER() over(order by id asc) as 'rowNumber', * from table1

生成带序号的集合

2、再查询该集合的 第 1  到第 5条数据

select * from
(select ROW_NUMBER() over(order by id asc) as 'rowNumber', * from table1) as temp
where rowNumber between 1 and 5

declare @pagesize int; declare @pageindex int; set @pagesize = 3
 
set @pageindex = 1; --第一页
 
select * from (select ROW_NUMBER() over(order by id asc) as 'rowNumber', * from table1) as temp where rowNumber between (((@pageindex-1)*@pagesize)+1) and (@pageindex*@pagesize)
 
set @pageindex = 2; --第二页
 
select * from (select ROW_NUMBER() over(order by id asc) as 'rowNumber', * from table1) as temp where rowNumber between (((@pageindex-1)*@pagesize)+1) and (@pageindex*@pagesize)
 
set @pageindex = 3; --第三页
 
select * from (select ROW_NUMBER() over(order by id asc) as 'rowNumber', * from table1) as temp where rowNumber between (((@pageindex-1)*@pagesize)+1) and (@pageindex*@pagesize)
 
set @pageindex = 4;--第四页
 
select * from (select ROW_NUMBER() over(order by id asc) as 'rowNumber', * from table1) as temp where rowNumber between (((@pageindex-1)*@pagesize)+1) and (@pageindex*@pagesize)

 下面我们来写个存储过程分页
