Question

我正在寻求帮助，我可以通过ironpython脚本将sql数据导入数据库。

目前我的脚本如下，首先运行此脚本：

import clr;
import System;

clr.AddReference("TCAdmin.SDK");
from TCAdmin.SDK.Misc import Random;
from System import String;

ThisService.Variables["MySQLUser"] = String.Format("exile_{0}",     ThisService.ServiceId);
ThisService.Variables["MySQLPassword"] = Random.RandomString(10,True,True);
ThisService.Save();

然后这个脚本运行：

import clr;
import System;

clr.AddReference("TCAdmin.DatabaseProviders.MySql");
clr.AddReference("TCAdmin.SDK");
from TCAdmin.DatabaseProviders.MySql import MySqlManager;
from System import String;

mysql_server="localhost";
mysql_root="root";
mysql_password="Password";

with MySqlManager() as mysql:
 escapeduser=mysql.PrepareSqlValue(ThisService.Variables["MySQLUser"]);
 escapedpass=mysql.PrepareSqlValue(ThisService.Variables["MySQLPassword"]);
 mysql.Connect(String.Format("Data Source={0};User Id={1};Password={2};Pooling=False;", mysql_server, mysql_root, mysql_password));

 mysql.ExecuteNonQuery(String.Format("DROP DATABASE IF EXISTS {0};", escapeduser));
 if mysql.Execute(String.Format("SELECT COUNT(*) as count FROM mysql.user WHERE user='{0}' AND host='localhost';", escapeduser)).Rows[0].Item[0] == 1 :
  mysql.ExecuteNonQuery(String.Format("DROP USER {0}@localhost;", escapeduser));

 mysql.ExecuteNonQuery(String.Format("CREATE DATABASE {0};", escapeduser));
 mysql.ExecuteNonQuery(String.Format("GRANT ALL PRIVILEGES ON {0}.* TO '{0}'@'localhost' IDENTIFIED BY '{1}';", escapeduser, escapedpass));

 mysql.ExecuteNonQuery(String.Format("USE '{0}';", escapeduser));
 mysql.ExecuteNonQuery(String.Format("""CREATE TABLE IF NOT EXISTS `account` (
  `uid` varchar(32) NOT NULL,
  `clan_id` int(11) UNSIGNED DEFAULT NULL,
  `name` varchar(64) NOT NULL,
  `money` double NOT NULL DEFAULT '0',
  `score` int(11) NOT NULL DEFAULT '0',
  `kills` int(11) UNSIGNED NOT NULL DEFAULT '0',
  `deaths` int(11) UNSIGNED NOT NULL DEFAULT '0',
  `first_connect_at` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `last_connect_at` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `last_disconnect_at` datetime DEFAULT NULL,
  `total_connections` int(11) UNSIGNED NOT NULL DEFAULT '1'
 ) ENGINE=InnoDB DEFAULT CHARSET=utf8;""", escapeduser));

当我运行脚本时，我收到错误：

您的SQL语法有错误;查看与您的MySQL服务器版本对应的手册，以便在第1行的“exile_2”附近使用正确的语法

TCAdmin.SDK.Database.DatabaseException：SQL语法中有错误;检查与MySQL服务器版本对应的手册，以便在第1行的''exile_2''附近使用正确的语法---＆gt;您的SQL语法有错误;检查与MySQL服务器版本对应的手册，以便在第1行“exile_2”附近使用正确的语法---内部异常堆栈跟踪结束---在Microsoft.Scripting.Interpreter.ThrowInstruction.Run（InterpretedFrame框架））在Microsoft.Scripting.Interpreter.LunLnsda.Run2 [T0，T1，TRet]的Microsoft.Scripting.Interpreter.Interpreter.Run（InterpretedFrame框架）中的Microsoft.Scripting.Interpreter.Interpreter.RunInstructions（InterpretedFrame框架）（T0 arg0， T1 arg1）位于TCAdmin.SDK.Scripting.Engines的Microsoft.Scripting.Hosting.ScriptSource.Execute（ScriptScope范围）的IronPython.Compiler.RuntimeScriptCode.InvokeTarget（范围范围）中的IronPython.Compiler.PythonScriptCode.RunWorker（CodeContext ctx）。 TCAdmin.GameHost上的TCAdmin.GameHosting.SDK.Objects.GameScript.ExecuteEventScripts（ScriptEngineManager scriptEngineManager，ServiceEvent eventScript，ObjectList脚本）中的TCAdmin.SDK.Scripting.ScriptEngineManager.Execute（）上的IronPythonEngine.Execute（凭证凭证） ing.AutomationProcesses。Ձ（）at TCAdmin.GameHosting.Automation.AutomationProcesses.Start（）at TCAdmin.TaskScheduler.ModuleApi.StepBase.Start（Object arguments）

所以我能够通过使用以下脚本导入实际的SQL文件来解决这个问题。

import clr;
import System;

clr.AddReference("TCAdmin.DatabaseProviders.MySql");
clr.AddReference("TCAdmin.SDK");
from TCAdmin.DatabaseProviders.MySql import MySqlManager;
from System import String;
from System.IO import File, Path;

mysql_server="localhost";
mysql_root="root";
mysql_password="Password";

if not ThisService.Variables.HasValue("MySQLUser") :
Script.Exit();


backupfile=Path.Combine(ThisService.RootDirectory, "dbname.sql");

with MySqlManager() as mysql:
escapeduser=mysql.PrepareSqlValue(ThisService.Variables["MySQLUser"]);
escapedpass=mysql.PrepareSqlValue(ThisService.Variables["MySQLPassword"]);
mysql.Connect(String.Format("Data Source={0};User Id={1};Password={2};Pooling=False;", mysql_server, mysql_root, mysql_password));

mysql.ExecuteNonQuery(String.Format("DROP DATABASE IF EXISTS {0};", escapeduser));
if mysql.Execute(String.Format("SELECT * FROM mysql.user WHERE user='{0}' AND host='localhost';", escapeduser)).Rows.Count == 1 :
mysql.ExecuteNonQuery(String.Format("DROP USER {0}@localhost;", escapeduser));

mysql.ExecuteNonQuery(String.Format("CREATE DATABASE {0};",  escapeduser));
mysql.ExecuteNonQuery(String.Format("GRANT ALL PRIVILEGES ON {0}.* TO '{0}'@'localhost' IDENTIFIED BY '{1}';", escapeduser, escapedpass));

if File.Exists(backupfile) :
with MySqlManager() as mysql2:
mysql2.Connect(String.Format("Data Source={0};Database={1};User Id=    {1};Password={2};Pooling=False;", mysql_server,     ThisService.Variables["MySQLUser"], ThisService.Variables["MySQLPassword"]));
mysql2.ImportDatabase(backupfile);
File.Delete(backupfile);
