SQL Server使用row_number分页的实现方法

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)
