这篇文章主要为大家详细介绍了SQL Server使用row_number分页的实现方法，具有一定的参考价值，感兴趣的朋友可以参考一下

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 = 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)
