使用ASP.NET窗體進行ODBC更新

Question

如何使用ASP.NET窗體（文本框）傳遞karthik@domain.com和kars@domain.com？

string MyConString = "DRIVER={MySQL ODBC 3.51 Driver};" + "SERVER=localhost;" + "DATABASE=new_db;" + "UID=root;" + "PASSWORD=password;" + "OPTION=3"; 

OdbcConnection MyConnection = new OdbcConnection(MyConString); 

OdbcCommand cmd = new OdbcCommand("UPDATE awm_create SET referral_email='karthik@domain.com' WHERE email='kars@domain.com'" , MyConnection); 

MyConnection.Open(); 

cmd.ExecuteNonQuery(); 

Answer 1

對不起我得到的答案是...

string MyConString = "DRIVER={MySQL ODBC 3.51 Driver};" + "SERVER=localhost;" + "DATABASE=new_db;" + "UID=root;" + "PASSWORD=password;" + "OPTION=3"; 

OdbcConnection MyConnection = new OdbcConnection(MyConString); 
      OdbcConnection MyConnection = new OdbcConnection(MyConString); 
      OdbcCommand cmd = new OdbcCommand("UPDATE awm_create SET referral_email=? WHERE email=?" , MyConnection); 

      cmd.Parameters.Add("@tb_refemail", OdbcType.VarChar, 255).Value = tb_refemail.Text.Trim(); 
      cmd.Parameters.Add("@tb_email", OdbcType.VarChar, 255).Value = lblemail.Text; 

      MyConnection.Open(); 
      cmd.ExecuteNonQuery();

你將不得不在兩個asp.net文本框控件添加到Web表單和回發時（使用的IsPostBack標誌），你可以從文本框在pageLoad的事件拉的電子郵件地址...即像：

private void Page_Load() 
{ 
    if(Page.IsPostBack) 
    { 
     // add validation here for the text boxes if you need... 
     string refEmail= txtReferralEmail.Text.Trim(); 
     string email = txtEmail.Text.Trim(); 

     //then you can do something like this: 

     var sql = string.Format("UPDATE awm_create SET referral_email='{0}' WHERE email='{1}'", refEmail, email); 

     OdbcCommand cmd = new OdbcCommand(sql , MyConnection); 
     try{ 
      MyConnection.Open(); 
      cmd.ExecuteNonQuery(); 
     }Catch(Exception e){ 
      // log your exception or whatever you need to do 
     } 
    } 
} 

不要忘記你需要兩個文本框添加到您的aspx形式與名稱txtReferralEmail和txtEmail。
