Question

The below is my code to create account in my project. The code is working perfect till Response.Write(iduser) but the UPDATE command is not working. No error found using exception but MySQL’s record is not updated.

    try
                {

                    string pet1 = "[e-mail]";
                    string MyConString = "DRIVER={MySQL ODBC 3.51 Driver};" + "SERVER=localhost;" + "DATABASE=newtest;" + "UID=root;" + "PASSWORD=**********;" + "OPTION=3";
                    OdbcConnection MyConnection = new OdbcConnection(MyConString);
                    OdbcCommand cmd = new OdbcCommand("Select id_user from awm_accounts where email=?", MyConnection);
                    cmd.Parameters.Add("@val1", OdbcType.VarChar, 255).Value = pet1;
                    MyConnection.Open();
                    OdbcDataReader dr = cmd.ExecuteReader();
                    if (dr.HasRows == false)
                    {
                        throw new Exception();
                    }
                    if (dr.Read())
                    {
                        int iduser = Convert.ToInt32(dr[0].ToString());
                        Account acct = new Account();
                        acct.Email = username.Text + domain.Text;
                        acct.MailIncomingLogin = username.Text + domain.Text;
                        acct.MailIncomingHost = "imap." + DropDownList1.SelectedValue;
                        acct.MailIncomingPassword = password.Text;
                        acct.MailIncomingPort = 993;
                        acct.MailOutgoingHost = "smtp." + DropDownList1.SelectedValue;
                        acct.MailOutgoingPort = 465;
                        acct.MailIncomingProtocol = IncomingMailProtocol.Imap4;
                        acct.MailOutgoingAuthentication = true;
                        acct.DefaultAccount = false;
                        acct.IDUser = 1;
                        integr.CreateUserFromAccount(acct);
                        Response.Write(iduser);
                        if (!IsPostBack)
                        {
                            cmd = new OdbcCommand("UPDATE awm_accounts SET id_user=? WHERE email=? ", MyConnection);
                            cmd.Parameters.Add("@tb_nickname", OdbcType.Int, 11).Value = iduser;
                            cmd.Parameters.Add("@tb_fullname", OdbcType.VarChar, 255).Value = username.Text + domain.Text;
cmd.ExecuteNonQuery();
                        }
                    }
                    MyConnection.Close();
                }
            catch (Exception exp)
            {
                Response.Write(exp);
            }

I’m not sure about the Response.Write part but I am sure that you create a SQLCommand but never actually execute it.

Did you forget to put a cmd.executeNonScalar() in there?
