Data inserted simultaneously two MySQL database (C #)

I have this functionality is achieved when inserting data to a remote MySql database, insert a same data in the same local database MySql.
During insertion, at the same time I did not connect the two databases. Process is as follows:

• First, insert data using SQL statements to a remote database
• Then close the connection to the remote database
• And then start to connect the local database
• Then use SQL statements to insert data into a local database
• Finally, turn off the local database and remote database connection

Part of the code as follows:

• connect is used to connect the database, the remote database if the connection is not on, it is connected to the local database. judge for judgment, 1 represents a remote database, the local database is connected represents 0.
• disconnect the current connection is disconnected database.
• connectlocal is connected to a local database.

sql = "insert into doctor(user,pwd,reg_date) VALUE ('" + MD5_new_admin + "','" + password2 + "',now());";
Goal_Mysql_var.mysql.exec_mysql_command_execute(sql);

mysql_none mn = new mysql_none();
if (mn.getjudge().ToString() == "1") 
{
    mn.disconnect();
    mn.connect1ocal();
    sql = "insert into doctor(user,pwd,reg_date,judge) VALUE ('" + MD5_new_admin + "','" + password2 + "',now(),1);";
    Goal_Mysql_var.mysql.exec_mysql_command_execute(sql);
    mn.disconnect();
    mn.connect();
}

    try
    {
        conn.Open();
        judge = 1;
    }
    catch (Exception ee)
    {
    //连接MySQL数据库出错  此处一般是服务器端出错，或者本机网络突然崩溃  只要连接语句无错误  几乎不会再此处出现异常
    //   Console.WriteLine("first..." + ee.Message);
        conn = new MySqlConnection("Server=localhost;UserId=root;Password=123456;Database=vr;Charset=utf8");//连接MySQL本地数据库
