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 = 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)
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)
