其实在很多时候设计的度还是要把握的，不至于让自己陷入【非要把它设计成万能的分页存储过程】的怪圈中才是最重要的，因为我们还要留出时间还解决其他的很多问题，个人认为适度就可以了，留出一定的空间。也因为万能是不存在的，万物在一定的范畴之内都是合理的，出了范畴可能就没有合理的了。

         分页存储过程大致有下列几种

1、 利用Not in 和select top

2、 利用id大于多少和select top

3、 利用sql中的游标

4、临时表

 可以参看网上的以下链接

   C#中常用的分页存储过程小结
http://read.newbooks.com.cn/info/174545.html

         在2005中我们的选择就多了，可以利用新语法CTE（公用表表达式）,关于CTE的介绍大家可以参看博客园中一位仁兄的系列教程

         http://www.cnblogs.com/nokiaguy/archive/2009/01/31/1381562.html

         或者干脆上微软的官网

http://msdn.microsoft.com/zh-cn/library/ms190766(SQL.90).aspx

查看具体内容。

         除此之外还可以利用在2005中新增的一些函数，分别是：row_number(),rank,dense_rank,ntile，这些新函数是您可以有效的分析数据以及向查询饿结果行提供排序值。您可能发现这些新函数有用的典型方案包括：将连续整数分配给结果行，以便进行表示、分页、计分和绘制直方图。

         详细介绍参见下列链接

  http://blog.csdn.net/htl258/archive/2009/03/20/4006717.aspx

         我这里主要使用的就是row_number()结合新语法CTE，先贴上我的存储过程。设计，开发，测试存储过程和相关的C#代码就花费我两天的时间，不过后面的相似界面就很快了，一上午就可以搞两个分页显示的页面，就算是复杂的查询，一上午也可以搞定。

　　下面的存储过程没有将总页数和总条目数返回，如果你有兴趣，可以自己加上，可以参看 C#中常用的分页存储过程小结中的下列部分

　　Declare @sql nvarchar(4000);
Declare @totalRecord int;
--计算总记录数
if (@SqlWhere ='''' or @SqlWhere='' or @sqlWhere is NULL)
set @sql = 'select @totalRecord = count(*) from ' + @TableName
else
set @sql = 'select @totalRecord = count(*) from ' + @TableName + ' where ' + @sqlWhere
EXEC sp_executesql @sql,N'@totalRecord int OUTPUT',@totalRecord OUTPUT--计算总记录数

--计算总页数

select @TotalPage=@totalRecord --CEILING((@totalRecord+0.0)/@PageSize)

存储过程SQL如下，支持不定列，不定条件，多表联合，排序任意
代码如下：

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
--Declare @sql nvarchar(4000);
--Declare @totalRecord int;
----计算总记录数
--if (@SqlWhere ='''' or @SqlWhere='' or @sqlWhere is NULL)
--set @sql = 'select @totalRecord = count(*) from ' + @TableName
--else
--set @sql = 'select @totalRecord = count(*) from ' + @TableName + ' where ' + @sqlWhere
--EXEC sp_executesql @sql,N'@totalRecord int OUTPUT',@totalRecord OUTPUT--计算总记录数
--
----计算总页数
