Answer 1

您需要将导入放在包定义中：

package dbconfig
{
    import mx.controls.Alert;

    public class DBConn
    {
        private var dbConn:SQLConnection;
        private var dbFile:File;

        public function DBConn()
        {
            this.openConnection(); 
        }

        public function openConnection(){
            dbFile = File.applicationStorageDirectory.resolvePath("accounting.sqlite");
            dbConn = new SQLConnection();

            try 
            {
                dbConn.open(dbFile);
                Alert.show("asdf");
            }
            catch(e:SQLError)
            {
                Alert.show("SQL Error Occured: ", e.message);
            }
        }
    }
}

是的，与Java不同，您必须导入所有要使用的类，即使您完全符合它们的要求。根据标签来判断我认为你知道这一点，但是SQLConnection和File只是Air，所以不能在普通的flash播放器中运行。
