最近由于制作任务编辑器，需要连接到数据库中进行一些任务数据的操作，而我们存放任务数据的数据库中MYSQL，所以就找了一下AS3接连MYSQL数据库的资料。

找到一个好东西：ActionScript 3 MySql Driver，用SVN的童鞋可以直接checkout:?

为了使用简单，我做了一个简单的包装类(包含一个数据结构)：

package com.easily.ds 
{ 
    public class DataBaseData 
    { 
        public var host:String; 
        public var port:int; 
        public var username:String; 
        public var password:String; 
        public var database:String; 
    } 
} 
?
package com.easily.util 
{ 
    import com.easily.ds.DataBaseData; 
    import com.maclema.mysql.Connection; 
    import com.maclema.mysql.Field; 
    import com.maclema.mysql.MySqlResponse; 
    import com.maclema.mysql.MySqlToken; 
    import com.maclema.mysql.ResultSet; 
    import com.maclema.mysql.Statement; 
      
    import flash.events.Event; 
    import flash.events.EventDispatcher; 
      
    import mx.rpc.AsyncResponder; 
  
    /**

    public class DataBase extends EventDispatcher 
    { 
        private var mDataBase:DataBaseData; 
        private var mConnection:Connection; 
          
        public function DataBase(database:DataBaseData) 
        { 
            mDataBase = database; 
        } 
          
        public function connect():void
        { 
            mConnection = new Connection(mDataBase.host, mDataBase.port,  
                mDataBase.username, mDataBase.password, mDataBase.database); 
            mConnection.addEventListener(Event.CONNECT, onConnected); 
              
            mConnection.connect(); 
              
            function onConnected(event:Event):void
            { 
                mConnection.removeEventListener(Event.CONNECT, onConnected); 
                  
                dispatchEvent(event); 
            } 
        } 
          
        public function disconnect():void
        { 
            mConnection.disconnect(); 
        } 
          
        public function select(sql:String, completeHandler:Function, errorHandler:Function = null):void
        { 
            var st:Statement = mConnection.createStatement(); 
            var token:MySqlToken = st.executeQuery(sql); 
            var responder:AsyncResponder = new AsyncResponder(resultHandler, faultHandler, token); 
            token.addResponder(responder);

                    while (result.next()) 
                    { 
                        var item:Object = {}; 
                        for each (var field:Field in fieldList) 
                        { 
                            item[field.getName()] = result.getString(field.getName());
