找到一個好東西：ActionScript3MySqlDriver，用SVN的童鞋可以直接checkout:

http://assql.googlecode.com/svn/trunk/為了使用簡單，我做了一個簡單的包裝類(包含一個數(shù)據(jù)結(jié)構(gòu))：

packagecom.easily.ds{publicclassDataBaseData{publicvarhost:String;publicvarport:int;publicvarusername:String;publicvarpassword:String;publicvardatabase:String;}}

packagecom.easily.util{importcom.easily.ds.DataBaseData;importcom.maclema.mysql.Connection;importcom.maclema.mysql.Field;importcom.maclema.mysql.MySqlResponse;importcom.maclema.mysql.MySqlToken;importcom.maclema.mysql.ResultSet;importcom.maclema.mysql.Statement;importflash.events.Event;importflash.events.EventDispatcher;importmx.rpc.AsyncResponder;/***@authorEasily*/publicclassDataBaseextendsEventDispatcher{privatevarmDataBase:DataBaseData;privatevarmConnection:Connection;publicfunctionDataBase(database:DataBaseData){mDataBase=database;}publicfunctionconnect():void{mConnection=newConnection(mDataBase.host,mDataBase.port,mDataBase.username,mDataBase.password,mDataBase.database);mConnection.addEventListener(Event.CONNECT,onConnected);mConnection.connect();functiononConnected(event:Event):void{mConnection.removeEventListener(Event.CONNECT,onConnected);dispatchEvent(event);}}publicfunctiondisconnect():void{mConnection.disconnect();}publicfunctionselect(sql:String,completeHandler:Function,errorHandler:Function=null):void{varst:Statement=mConnection.createStatement();vartoken:MySqlToken=st.executeQuery(sql);varresponder:AsyncResponder=newAsyncResponder(resultHandler,faultHandler,token);token.addResponder(responder);functionresultHandler(result:Object/*ResultSet*/,token:Object/*MySqlToken*/):void{vardata:Array=[];if(resultisResultSet){varfieldList:Array=result.getColumns();while(result.next()){varitem:Object={};foreach(varfield:FieldinfieldList){item[field.getName()]=result.getString(field.getName());}data.push(item);}}completeHandler(data);}functionfaultHandler(info:Object,token:Object):void{if(errorHandler==null)return;errorHandler();}}publicfunctioninsert(sql:String,completeHandler:Function,errorHandler:Function=null):void{varst:Statement=mConnection.createStatement();vartoken:MySqlToken=st.executeQuery(sql);varresponder:AsyncResponder=newAsyncResponder(resultHandler,faultHandler,token);token.addResponder(responder);functionresultHandler(result:Object/*MySqlResponse*/,token:Object/*MySqlToken*/):void{completeHandler(result.insertID);}functionfaultHandler(info:Object,token:Object):void{if(errorHandler==null)return;errorHandler();}}publicfunctionremove(sql:String,completeHandler:Function,errorHandler:Function=null):void{varst:Statement=mConnection.createStatement();vartoken:MySqlToken=st.executeQuery(sql);varresponder:AsyncResponder=newAsyncResponder(resultHandler,faultHandler,token);token.addResponder(responder);functionresultHandler(result:Object/*MySqlResponse*/,token:Object/*MySqlToken*/):void{completeHandler();}functionfaultHandler(info:Object,token:Object):void{if(errorHandler==null)return;errorHandler();}}}}

其中有3個方法，select,insert,remove，分別對應(yīng)了SQL語句中的select,insert,delete

如何將AS3連接到MySQL數(shù)據(jù)庫上

用法很簡單，先連接：

vardatabaseData:DataBaseData=newDataBaseData();databaseData.host="127.0.0.1";databaseData.database="game";databaseData.password="123456";databaseData.port=3306;databaseData.username="root";vardataBase:DataBase=newDataBase(databaseData);dataBase.addEventListener(Event.CONNECT,onConnected);dataBase.connect();functiononConnected(event:Event):void{dataBase.removeEventListener(Event.CONNECT,onConnected);dispatchEvent(newEvent(Event.COMPLETE));}

如果不需要用了可以先斷開連接：

dataBase.disconnect();

下面是select語句：

varsql:String="selectid,namefrom`npc`";dataBase.select(sql,endQuery);functionendQuery(data:Array):void{varnpcList:Array=[];foreach(varitem:Objectindata){varnpc:Object={id:item.id,name:item.name};npcList.push(npc);}}

insert語句用法會返回一個insertID，也就是插入的那條數(shù)據(jù)的ID。
