ADO.NET,你的极限是什么?--ADO.NET之另类绑定

在.NET应用中，数据库的成分不仅是整个.NET框架重要的部分,也是设计页面和后台的关键.

ADO.NET你的极限是什么?

1. 页面文件有两个TEXTBOX控件用来设置查找范围。下面一个DATAGRID，用来绑定数据库的数据。

2.后台代码片段:

public partial class FinanceReport : PageBase

{

public static String CONN = System.Configuration.ConfigurationManager.AppSettings.Get("ConnectionString");

protected void Page_Load(object sender, EventArgs e)

{

PageBegin(true, false);

if (IsPostBack)

return;

FromDate.Text = DateTime.Now.Year.ToString() + "-1-1";

ToDate.Text = (DateTime.Now.Year + 1).ToString() + "-1-1";

PageFill();

}

protected void QueryButton_Click(object sender, EventArgs e)

{

if (DateUtil.IsDateTime(FromDate.Text) == false || DateUtil.IsDateTime(FromDate.Text) == false)

{

Session["CM_report_FromDate"] = "";

Session["CM_report_ToDate"] = "";

}

else

{

Session["CM_report_FromDate"] = FromDate.Text;

Session["CM_report_ToDate"] = ToDate.Text;

}

BuildTable();

}

protected void PageFill()

{

if (Session["CM_Year"] != null)

{

FromDate.Text = Session["CM_Year"] + "-1-1";

ToDate.Text = int.Parse(Session["CM_Year"].ToString()) + 1 + "-1-1";

}

if (Session["CM_report_FromDate"] != null)

FromDate.Text = Session["CM_report_FromDate"].ToString();

if (Session["CM_report_ToDate"] != null)

ToDate.Text = Session["CM_report_ToDate"].ToString();

BuildTable();

}

protected void BuildTable()

{

SqlConnection conn = new SqlConnection();

conn.ConnectionString = CONN;

SqlCommand command = new SqlCommand();

command.CommandText = "CM_Test";

command.CommandType = CommandType.StoredProcedure;

command.Connection = conn;

SqlParameter param = new SqlParameter("@FromDate", SqlDbType.DateTime);

if (DateUtil.IsDateTime(FromDate.Text) == false)

{

param.Value = DateTime.Parse(DateTime.Now.Year.ToString() + "-1-1");

}

else

{

param.Value = DateTime.Parse(FromDate.Text);

}

command.Parameters.Add(param);

param = new SqlParameter("@ToDate", SqlDbType.DateTime);

if (DateUtil.IsDateTime(ToDate.Text) == false)

{

param.Value = DateTime.Parse((DateTime.Now.Year + 1).ToString() + "-1-1");

}

else

{

param.Value = DateTime.Parse(ToDate.Text);

}

command.Parameters.Add(param);

DataSet ds = new DataSet();

SqlDataAdapter da = new SqlDataAdapter();

da.SelectCommand = command;

da.Fill(ds);

DG.DataSource = ds;

DG.DataBind();

}

说明：后台代码中设计时间范围的小技巧很好用，借助JS，点击TEXTBOX控件的时候就会激发封装好的日历，然后选择日期，就可以自动完成填充了。下面就是绑定了。调用了“CM_Test”

3.数据库存储过程，精彩的来了：

    @ToDate datetime

    insert @tmp values('SIS服务合同额 :',@ic,@asb,@sales)

    select * from @tmp
GO

说明：。。。这个存储过程直接搞定这个页面，数据库也可以这样完成，我也是第一次接触这样的存储过程。里面带"Money"的变量都是数据库存储金额的类型，这个页面的功能是统计功能。红字的就直接显示在表里面了--即“统计项”；ic--即集成合同；asb--即ASB合同；Sales--即销售合同。
