(3)订单统计后台页面代码
public partial class OrderStatistics : System.Web.UI.Page { OrderinfoManager bll = new OrderinfoManager(); protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { DataSet ds = bll.GetData(); for (int i = 0; i < ds.Tables[0].Rows.Count; i++) { this.lblTname.Text = ds.Tables[0].Rows[0]["Tname"].ToString(); this.lblBegin_sta.Text = ds.Tables[0].Rows[0]["Begin_sta"].ToString(); this.lblEnd_sta.Text = ds.Tables[0].Rows[0]["End_sta"].ToString(); this.lblStart_date.Text = ds.Tables[0].Rows[0]["Start_date"].ToString(); this.lblStart_time.Text = ds.Tables[0].Rows[0]["Start_time"].ToString(); this.lblCount.Text = ds.Tables[0].Rows[0][5].ToString(); } } } } DAL层： public DataSet GetData() { string sql = $"select Tname,Begin_sta,End_sta,Start_date,Start_time, COUNT(*) from Traininfo inner join Carinfo on Traininfo.Tid=Carinfo.Tid inner join Orderinfo on Carinfo.Cid=Orderinfo.Cid group by Tname,Begin_sta,End_sta,Start_date,Start_time"; return dbHelper.GetData(sql); }
3、遇到的问题:
(1)涉及到多表联查
(2)很多想实现的效果因为能力有限没办法实现，需要前端技术
4、解决的方法:
(2)技术能力方面需要利用这个暑假做提升
5、项目燃尽图更新(此内容一周已更新)
