Question

我有一个mysql插入程序，设置为在另一个程序完成后运行...

我这样做的方式是，初始程序的最后一件事是启动mysql插入程序......这是方法

  ProcessStartInfo startInfo = new ProcessStartInfo();
            startInfo.FileName = "PFML_STATES_MYSQL.exe";
           startInfo.Arguments = args[0];
            Process.Start(startInfo);
            Environment.Exit(0);

我目前正从mysql插入器中的这段代码中获取堆栈跟踪

public void ClearAll(string args)
        {
            using (MySqlCommand command = new MySqlCommand())
            {
                command.Connection = this.connection;
                if (args.Equals("ny"))
                    command.CommandText = "delete from jurisdiction where offender_id  IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1);delete from offenders_locations where offender_id  IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1);delete from vehicles where offenders_id  IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1);delete from alias where offenders_id  IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1);delete from marks where offenders_id  IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1);delete from offender_pictures where offenders_id  IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1);delete from sentencing_info where offenders_id  IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1);delete from crimes where offendersXREF  IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1);delete from offender_pictures_additional where offenders_id IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1);";
                else
                {
                    command.CommandText = "delete from jurisdiction where offender_id  IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1 and (county_id = 360052 or county_id = 360099 or county_id = 360030));delete from offenders_locations where offender_id  IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1 and (county_id = 360052 or county_id = 360099 or county_id = 360030));delete from vehicles where offenders_id  IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1 and (county_id = 360052 or county_id = 360099 or county_id = 360030));delete from alias where offenders_id  IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1 and (county_id = 360052 or county_id = 360099 or county_id = 360030));delete from marks where offenders_id  IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1 and (county_id = 360052 or county_id = 360099 or county_id = 360030));delete from offender_pictures where offenders_id  IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1 and (county_id = 360052 or county_id = 360099 or county_id = 360030));delete from sentencing_info where offenders_id  IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1 and (county_id = 360052 or county_id = 360099 or county_id = 360030));delete from crimes where offendersXREF  IN (select offender_id from offenders WHERE offender_id like 'NY%' AND risk_level !=1 and (county_id = 360052 or county_id = 360099 or county_id = 360030));delete from offender_pictures_additional where offenders_id IN (select offender_id from offenders WHERE offender_id like 'NY%' AND (county_id = 360052 or county_id = 360099 or county_id = 360030) AND risk_level !=1);";
                }
                command.ExecuteNonQuery();
            }
        }

我删除了堆栈跟踪，因为我很傻......但它说无法通过command.executereader（）＆gt;立即完成类似非阻塞套接字操作的操作。 command.executenonquery（）

关于这个问题的真正有趣的部分是它只发生在初始程序启动mysql插入器时，如果我手动启动它完全运行的插入器......

错误：

MySql.Data.MySqlClient.MySqlException：期间遇到致命错误命令执行。 ---＆GT; MySql.Data.MySqlClient.MySqlException：致命尝试读取结果集时遇到错误。 ---＆GT; MySql.Data.MySqlClient.MySqlException：从流中读取失败。 ---＆GT; System.IO.IOException：无法从中读取数据传输连接：无法阻塞套接字操作马上完成。 ---＆GT; System.Net.Sockets.SocketException：A 非阻塞套接字操作无法立即完成

Answer 1

由于这个问题并不持久，我没有很好的答案......

但是我重新启动了服务器两次并自行修复了它。
