篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Row_Number实现分页相关的知识，希望对你有一定的参考价值。
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
完整的Sql语句
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
------------------------------
Alter Procedure PagePager
@TableName varchar(80),
@File varchar(1000),---
@Where varchar(500),---带and连接
@OrderFile varchar(100), -- 排序字段
@OrderType varchar(10),--asc:顺序，desc:倒序
@PageSize varchar(10), --
@PageIndex varchar(10) --
as
if(ISNULL(@OrderFile, '') = '')
begin
set @OrderFile = 'ID';
end
if(ISNULL(@OrderType,'') = '')
begin
set @OrderType = 'asc'
end
if(ISNULL(@File,'') = '')
begin
set @File = '*'
end
declare @select varchar(8000)
set @select = ' select ' + @File + ' from ( select *,ROW_NUMBER() over(order by ' + @OrderFile + ' '+ @OrderType + ') as ''rowNumber'' from ' + @TableName + ' where 1=1 ' + @Where + ' ) temp where rowNumber between (((' + @PageIndex + ' - 1) * ' + @PageSize + ')+1) and (' + @PageIndex + '*'+ @PageSize+')'
exec(@select)
