要更新的odbc语法

Question

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=?' 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 = tb_email.Text.Trim();

MyConnection.Open();

cmd.ExecuteNonQuery();

如何使用表单提供referral_email和电子邮件？
