下面是存储过程（sqlserver2000下通过)

--最通用的分页存储过程
-- 获取指定页的数据

CREATE PROCEDURE Pagination

@tblName   varchar(255),       -- 表名

@strGetFields varchar(1000) = '*', -- 需要返回的列

@fldName varchar(255)='',      -- 排序的字段名

@PageSize   int = 10,          -- 页尺寸

@PageIndex int = 1,           -- 页码

@doCount bit = 0,   -- 返回记录总数, 非 0 值则返回

@OrderType bit = 0, -- 设置排序类型, 非 0 值则降序

@strWhere varchar(1500) = '' -- 查询条件 (注意: 不要加 where)

AS

declare @strSQL   varchar(5000)       -- 主语句字串2

declare @strTmp   varchar(110)        -- 临时变量

declare @strOrder varchar(400)        -- 排序类型

   set @strSQL = 'select count(*) as Total from ['+ @tblName +'] where '+ @strWhere

   else

   set @strSQL = 'select count(*) as Total from ['+ @tblName +']'

end

--以上代码的意思是如果@doCount传递过来的不是0，就执行总数统计。以下的所有代码都
--是@doCount为0的情况

else

begin

if @OrderType != 0

begin

   set @strTmp = '<(select min'
字串5
set @strOrder = ' order by ['+ @fldName +'] desc'

--如果@OrderType不是0，就执行降序，这句很重要！

end

--如果是第一页就执行以上代码，这样会加快执行速度
