# Row_Number实现分页

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 = 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)

Alter Procedure PagePager

@PageSize varchar(10), --

@PageIndex varchar(10) --

as

if(ISNULL(@OrderFile, '') = '')

begin

set @OrderFile = 'ID';

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+')'
