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

完整的Sql语句

declare @pagesize int; declare @pageindex int; set @pagesize = 3set @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)

以上就是本文的全部内容，希望对大家学习row_number分页有所帮助。
