分页显示
if exists(select * from sysobjects where name='stu')
drop table stu
go
/* 分页 */
create table stu
( id int )
go

declare @x int 
set @x = 1
while @x<=100
  begin
  insert into stu values(@x)
  set @x=@x+1
  end

/* 显示第一条记录 */
select top 1 * from stu

/* 显示第二条记录 */
select top 1 * from stu where id
  not in (select top 1 id from stu)
/* 每页5条,显示第一页 */
select top 5 * from stu

/* 显示第二页 */
select top 5 * from stu 
where id not in (select top 5 id from stu)
 
/* 显示第11页*/
select top 5 * from stu 
 where id not in (select top 50 id from stu)



create proc proc_page
@page int,
@size int
as
declare @sql varchar(200) --好大
set @sql='select top '+convert(varchar(5),@size)+' * from stu 
where id not in(select top '+convert(varchar(6),((@page-1)*@size))+' id from stu)'
exec (@sql)
go

高手发表下, 在C#怎么调用上面的存储过程;或者有更好的方法 Thanks

------解决方案--------------------
C# code
CREATE PROC P_TEST
@Name VARCHAR(20),
@Rowcount INT OUTPUT
AS
BEGIN
 SELECT * FROM T_Customer WHERE NAME=@Name
 SET  @Rowcount=@@ROWCOUNT
END
GO
----------------------------------------------------
--存储过程调用如下:
----------------------------------------------------
DECLARE @i INT
EXEC P_TEST 'A',@i OUTPUT
SELECT @i
--结果
/*
Name       Address    Tel                  
---------- ---------- -------------------- 
A          Address    Telphone 
(所影响的行数为 1 行)

            
-----------

--DotNet 部分(C#)
--WebConfig 文件:
----------------------------------------------------
......
 </system.web>
 
   <!-- 数据库连接字符串
   -->
 <appSettings>
      <add key="ConnectString" value="server=(local);User ID=sa;Password=;database=Test" />
</appSettings>
   
</configuration>
----------------------------------------------------
--C#代码:(用到两个测试控件,DataGrid1(用于显示绑定结果集合),Lable(用于显示存储过程返回单值)
----------------------------------------------------
//添加数据库引用
using System.Data.SqlClient;
......
 private void Page_Load(object sender, System.EventArgs e)
  {
   // 在此处放置用户代码以初始化页面
   String DBConnStr;
   DataSet MyDataSet=new DataSet();
   System.Data.SqlClient.SqlDataAdapter DataAdapter=new System.Data.SqlClient.SqlDataAdapter();
   DBConnStr=System.Configuration.ConfigurationSettings.AppSettings["ConnectString"];
   System.Data.SqlClient.SqlConnection myConnection = new System.Data.SqlClient.SqlConnection(DBConnStr);
   if (myConnection.State!=ConnectionState.Open) 
   {
    myConnection.Open();
   }   
   System.Data.SqlClient.SqlCommand myCommand = new System.Data.SqlClient.SqlCommand("P_Test",myConnection);
   myCommand.CommandType=CommandType.StoredProcedure;
   //添加输入查询参数、赋予值
   myCommand.Parameters.Add("@Name",SqlDbType.VarChar);
   myCommand.Parameters["@Name"].Value ="A";

   //添加输出参数
   myCommand.Parameters.Add("@Rowcount",SqlDbType.Int);
   myCommand.Parameters["@Rowcount"].Direction=ParameterDirection.Output;


   myCommand.ExecuteNonQuery();
   DataAdapter.SelectCommand = myCommand;

   if (MyDataSet!=null)
   {
     DataAdapter.Fill(MyDataSet,"table");
   }
   
   DataGrid1.DataSource=MyDataSet;
   DataGrid1.DataBind();
   //得到存储过程输出参数
   Label1.Text=myCommand.Parameters["@Rowcount"].Value.ToString();

   if (myConnection.State == ConnectionState.Open)
   {
    myConnection.Close();
   }

  }
----------------------------------------------------
运行以上代码即可(返回记录集合和存储过程返回值)
