以下是我在我的項目中創建帳戶的代碼。代碼工作完美,直到Response.Write(iduser)
但UPDATE命令不起作用。沒有發現使用異常的錯誤,但MySQL的記錄沒有更新。奇怪! MySQL更新無法正常工作
try
{
string pet1 = "[email protected]";
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);
}
你是否在使用UpdatePanel?如果是這樣,請刪除它,直到您修復了錯誤。 –
不。我在這段代碼中沒有使用UpdatePanel。 –
