一个SQL Server2000和2005都能用的分页方法

    (1)存储过程(SQL2000和2005下都可用):

USE [Northwind]
GO
/****** 对象:  StoredProcedure [dbo].[p_GetOrders]    脚本日期: 03/29/2010 23:00:19 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER  PROCEDURE [dbo].[p_GetOrders]
@strWhere   varchar(1500),   -- 查询条件 (注意: 不要加 where)
@PageSize    int = 50,          -- 页尺寸
@PageIndex   int = 1,           -- 页码
@PageCount   int out,           --总页数
@RecordCount int out            --总记录数
AS 
BEGIN
 declare @strSQL   varchar(5000)       -- 主语句
 declare @strTmp   varchar(110)        -- 临时变量
 declare @strOrder varchar(400)        -- 排序类型
 select @RecordCount=count(*) from SaleInvoices
 select @PageCount=ceiling(@RecordCount/@PageSize)
 set @strTmp = '<(select min'
 set @strOrder = ' order by OrderID desc'
 if @PageIndex = 1
 begin
     if @strWhere != ''   
     set @strSQL = 'select top ' + str(@PageSize) +' *  from Orders where ' + @strWhere + ' ' + @strOrder
     else
     set @strSQL = 'select top ' + str(@PageSize) +'  *   from Orders '+ @strOrder
     --如果是第一页就执行以上代码，这样会加快执行速度
 end
 else
 begin
 --以下代码赋予了@strSQL以真正执行的SQL代码
 set @strSQL = 'select top ' + str(@PageSize) +'  *  from Orders 
 where OrderID' + @strTmp + '(OrderID) from (select top ' + str((@PageIndex-1)*@PageSize) + ' OrderID from Orders' + @strOrder + ') as tblTmp)'+ @strOrder
 if @strWhere != ''
     set @strSQL = 'select top ' + str(@PageSize) +'  * from Orders 
      where OrderID' + @strTmp + '(OrderID) from 
    (select top ' + str((@PageIndex-1)*@PageSize) + ' OrderID from Orders where ' + @strWhere + ' '
         + @strOrder + ') as tblTmp) and ' + @strWhere + ' ' + @strOrder
 end 
 --print (@strSQL) 
 exec (@strSQL)
END

    使用:将存储过程中的Orders改为自己所要查询数据的表的名称,OrderID改为自己所用表中的标识字段(具有唯一值就可以)
    存储过程测试:

declare @PageCount int 
declare @RecordCount int
exec p_GetPaging '[no] like "%RB%"',10,3,@PageCount,@RecordCount

    (2)页面前台:

......
	<asp:TextBox ID="txtAllSearch" runat="server"></asp:TextBox>
        <asp:Button ID="btnAllSearch" runat="server" Text="搜索" onclick="btnAllSearch_Click" />
	<asp:GridView ID="GvSAll" runat="server">
        </asp:GridView>
        <asp:LinkButton ID="lbtnPre" runat="server" onclick="lbtnPre_Click" Text="1">1</asp:LinkButton>    
        <asp:LinkButton ID="lbtnNext"  runat="server" onclick="lbtnNext_Click" Text="2">2</asp:LinkButton> 
......

    注:按钮中的文本设为"1"和"2"
    (3)页面后台:

	private int PageSize = 5;  //全局变量
        private int PageIndex = 1;  //全局变量
	//获取数据方法
	protected DataTable getPageDataSource(string sqlWhere, int pageIndex, int pageSize)
        {
            string connStr = ConfigurationManager.AppSettings["MsSql2nd"].ToString();
            SqlConnection conn = new SqlConnection(connStr);
            conn.Open();
            string sql = "p_GetPaging";
            SqlCommand cmd = new SqlCommand(sql, conn);

        }
	//获取总页数

            cmd.Parameters.Add("@PageCount", SqlDbType.Int);
            cmd.Parameters["@PageCount"].Direction = ParameterDirection.Output;
            SqlDataReader sdr = cmd.ExecuteReader();
            DataTable dt = new DataTable();
            dt.Load(sdr);
            sdr.Dispose();
            conn.Close();
            //return dt;
	    int pageCount = (int)cmd.Parameters["@PageCount"].Value;
            return pageCount;
        }
	//搜索按钮事件
	protected void btnAllSearch_Click(object sender, EventArgs e)

            DataTable dt = getPageDataSource(sqlWhere, PageIndex, PageSize);
            this.GvSAll.DataSource = dt; ;
            this.GvSAll.DataBind();
        }
	//前一页事件
	protected void lbtnPre_Click(object sender, EventArgs e)
        {
            string sestr = this.txtAllSearch.Text.Trim();
            string sqlWhere = "";

            }
            else
            {

            }
            PageIndex = Convert.ToInt16(this.lbtnPre.Text);
            PageIndex -= 1;
            if (PageIndex<=1)
            {
                PageIndex = 1;
            }
            DataTable dt = getPageDataSource(sqlWhere, PageIndex, PageSize);
            this.lbtnPre.Text = PageIndex.ToString();
            this.lbtnNext.Text = (PageIndex + 1).ToString();
            this.GvSAll.DataSource = dt; ;
            this.GvSAll.DataBind();
        }
	//后一页事件
	protected void lbtnNext_Click(object sender, EventArgs e)
        {
            string sestr = this.txtAllSearch.Text.Trim();
            string sqlWhere = "";
            if (sestr == "")
            {
                sqlWhere = "";

            else
            {

            }
            PageIndex=Convert.ToInt16(this.lbtnNext.Text);
            PageIndex += 1;
	    int PageCount = getPageCount("", 1, 5);
            if (PageIndex>PageCount+1)
            {
                PageIndex = PageCount+1;
            }
            DataTable dt = getPageDataSource(sqlWhere, PageIndex, PageSize);
            this.lbtnNext.Text = PageIndex.ToString();
            this.lbtnPre.Text = (PageIndex - 1).ToString();
            this.GvSAll.DataSource = dt; ;
            this.GvSAll.DataBind();            
        }

    注:在两个翻页事件中利用了两按钮自身的文本值来保存参数,并相与影响
