flex4.5移动开发操作sqlite数据库

由于sdcard存储是只读模式，flex4.5移动开发操作sqlite数据库时，只能查询，不能insert，update，delete，所以初始化应用的时候要把sqlite的数据库copy的程序安装的目录下，代码如下：

? var dbFiledb:File = new File("/mnt/sdcard/erppos/erppos.db");??

????var dbWorkFile:File = File.applicationStorageDirectory.resolvePath("database/erppos.db");
????if(!dbWorkFile.exists){?
?????dbFiledb.copyTo(dbWorkFile);
????}

?

?

建立连接的时候：

file = File.applicationStorageDirectory.resolvePath("database/erppos.db");??????????? sqlConnection = new SQLConnection();?????????? ??????????? ??????????? sqlConnection.addEventListener(SQLEvent.OPEN,openHandler);?? ???sqlConnection.addEventListener(SQLErrorEvent.ERROR,errorHandler);?????????????? stmt = new SQLStatement();??????????? stmt.sqlConnection = sqlConnection;??????????? sqlConnection.open(file);
