分页存储过程的应用简单示例随笔（附所有代码）

       需要的自己拿着去用起，很简单的分页存储过程示例！！！

一.在SQL SERVER中先创建一个数据库表：

1 CREATE TABLE [dbo].[zhq_content](
2     [content_id] [bigint] NOT NULL primary key identity,
3     [columns_id] [smallint] NOT NULL,
4     [title] [nvarchar](100) COLLATE Chinese_PRC_CI_AS NULL,
5     [body] [text] COLLATE Chinese_PRC_CI_AS NULL,
6     [createdate] [datetime] NULL,
7     [modifieddate] [datetime] NULL,
8     [issuedate] [datetime] NULL
9     )

二，向表中随意插入数据

1 declare @id  int
2 set  @id=1
3
4 while(@id<360)
5 begin
6 INSERT INTO [ForeTechTest].[dbo].[zhq_contenttest]
7            ([columns_id]
8            ,[title]
9            ,[body]
10            ,[createdate]
11            ,[modifieddate]
12            ,[issuedate])
13      VALUES
14            (10
15            ,'title'+cast(@id as varchar)
16            ,'body'+cast(@id as varchar)
17            ,getdate()
18            ,getdate()
19            ,getdate());
20 set @id=@id+1;
21
22 end
23

三.构建页面效果

1 <head runat="server">
2     <title>分页显示</title>
3 </head>
4 <body>
5     <form id="form1" runat="server">
6     <div>
7     <table><tr><td>
8     <ul>
9       <asp:Repeater  EnableViewState="false" runat="server" ID="repeater">
10              <ItemTemplate>
11             <li> <%# DataBinder.Eval(Container, "DataItem.content_id")%>    --- <%# DataBinder.Eval(Container, "DataItem.body").ToString()%> ---    <%# DataBinder.Eval(Container, "DataItem.createdate").ToString()%></li>
12              </ItemTemplate>
13       </asp:Repeater>
14      </ul>
15       </td></tr></table>
16
17       <table><tr>
18       <td>
19           当前第<asp:Label ID="lblCurrentPage" runat="server" Text="Label"></asp:Label>页/总共<asp:Label
20               ID="lblPageCount" runat="server" Text="Label"></asp:Label>页/总共<asp:Label ID="lblCount"
21                   runat="server" Text="Label"></asp:Label>条</td><td>
22           <input id="btnFirst" type="button" value="first"  runat="server" onserverclick="btnFirst_ServerClick"  /></td>
23           <td><input id="btnPriority" type="button" value="priority"  runat="server" onserverclick="btnPriority_ServerClick"  /></td>
24           <td><input id="btnNext" type="button" value="next"  runat="server" onserverclick="btnNext_ServerClick"  /></td>
25           <td><input id="btnLast" type="button" value="last"  runat="server" onserverclick="btnLast_ServerClick"  /></td>
26           </tr>
27       </table>
28     </div>
29     </form>
30 </body>
31 </html>

四.别人写的二分制分页存储过程，不知道哪位大虾的，哈哈，拿过来用起，代码如下：

  1 set ANSI_NULLS ON
  2 set QUOTED_IDENTIFIER ON
  3 go
  4
  5
  6
  7 ALTER PROCEDURE [dbo].[ProcPagedSelectMax]
  8  (
  9   @tblName     nvarchar(200),        ----要显示的表或多个表的连接
10   @fldName     nvarchar(500) = '*',    ----要显示的字段列表
11   @pageSize    int = 10,        ----每页显示的记录个数
12  @page        int = 1,        ----要显示那一页的记录
13  @fldSort    nvarchar(200) = null,    ----排序字段列表或条件
14  @Sort        bit = 0,        ----排序方法，0为升序，1为降序(如果是多字段排列Sort指代最后一个排序字段的排列顺序(最后一个排序字段不加排序标记)--程序传参如：' SortA Asc,SortB Desc,SortC ')
15  @strCondition    nvarchar(1000) = null,    ----查询条件,不需where
16  @ID        nvarchar(150),        ----主表的主键
17  @Dist                 bit = 0,           ----是否添加查询字段的 DISTINCT 默认0不添加/1添加
18  @pageCount    int = 1 output,            ----查询结果分页后的总页数
19  @Counts    int = 1 output                ----查询到的记录数
20  )

32
33  declare @timediff datetime  --耗时测试时间差

       感觉速度还是相当快的..........如果要应用到其他的方面，修改下其他的参数即可。

显示如下：

为了安全通过控制

if (int.Parse(lblCurrentPage.Text.ToString()) <= 1)
        {
            pageIndex = 1;
        }
        else
        {
            pageIndex = int.Parse(lblCurrentPage.Text.ToString()) - 1;
        }

和if (int.Parse(lblCurrentPage.Text.ToString()) >= pageCount)
        {
            pageIndex = pageCount;
        }
        else
        {
            pageIndex = int.Parse(lblCurrentPage.Text.ToString()) + 1;
        }

控制范围不超出索引。

同样可以通过页面的生成过程来控制控件的显示状态：

protected void Page_Load(object sender, EventArgs e)
    {
        if (Request.QueryString["pageIndex"] == null)
        {
            pageIndex = 1;
        }
        else
        {
            pageIndex = int.Parse(Request.QueryString["pageIndex"].ToString());
        }

        BindContent(out pageCount, out counts, 20, pageIndex);
        lblPageCount.Text = pageCount.ToString();
        lblCount.Text = counts.ToString();
        lblCurrentPage.Text = pageIndex.ToString();
        if (lblCurrentPage.Text.ToString() == pageCount.ToString())
        {
            btnNext.Visible = false;
        }
        else
        {
            btnNext.Visible = true;
        }
        if (lblCurrentPage.Text.ToString() == "1")
        {
            btnFirst.Visible = false;
        }
        else
        {
            btnFirst.Visible = true;
        }

    }

主要是需要掌握页面的生命周期，加以控制。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。
