原创：也谈SqlServer分页

今天也来谈谈SqlServer的分页：

1. 使用游标分页。
2. 使用top分页。
3. 使用ROW_NMUBER()分页(SQLServer 2005)。

对应表：

sql 代码

if exists (select name from sysobjects where name='produce' and type='u')
drop table produce
go

create table produce(
   p_id varchar(64) primary key,
  p_name varchar(50),
  p_price float,
  p_path varchar(100)
)
go

以下是使用top分页的存储过程：

sql 代码

if exists(select name from sysobjects where name='produce_proc' and type='p')
drop procedure produce_proc
go
create procedure produce_proc
@pageSize int,      --每页的记录数
@index int          --从第几条记录开始
as
  begin
  set nocount on
declare @sql nvarchar(3000)
if @index>@pageSize
     begin
  set @index = @index - @pageSize
       set @sql='select top '+cast (@pageSize as varchar(8))+' * from produce where p_id>(
          select max(p_id) from (select top '+cast (@index as varchar(8))+' p_id from produce order by p_id)
        as t)
        order by p_id'
  end
else
  begin
      set @sql = 'select top '+cast (@pageSize as varchar(8))+'* from produce order by p_id'
  end
execute sp_executesql @sql   --调用系统存储过程忧化动态执行效率
 set nocount off
end

 

ROW_NUMBER()分页：

sql 代码

SELECT * FROM (SELECT p_id,p_name,p_path,p_price,ROW_NUMBER() OVER (ORDER BY p_id) AS 'RowNumber' FROM produce) a  WHERE a.RowNumber BETWEEN 开始记录 AND 结束记录数
