私は2つのテーブルでのMySQL DBを持っている：
1.カテゴリ - カテゴリID /カテゴリ/説明
2.写真 - PHOTOID /カテゴリID/photodescription /写真フレックス＆PHP - PHPのサービスで挿入クエリ
そして、私は、Flash Builderによって自動的に作成されたサービス（CategoryService.php）を持っていますが、2番目のテーブルを取得できません！私は2スパークリストを持っているFlash Builderで

、最初のものは、すべてcategorysを持っており、それが通信員写真と他のものを移入したときにselectedItem私はしたいです。 私はデータベースで動作するクエリを持っていますが、PHPに挿入することはできません。 これはクエリです：
SELECT TC.*, TP.photodescription , TP.photo FROM category TC inner join photos TP on TC.categoryId = TP.categoryId
私はこれをどのように行うことができます！ 「聞いてくれてありがとう」と感謝します。
EDIT：
<fx:Script>

これは私の.mxmlの一例です。
「selectedItem」では、categoryIdに基づいて2番目のリストを変更する方法はありますか。
いくつか例を教えてください。 ありがとうございました..
おかげで全体の説明のために多くのことを！私は本当に試しましたが、私はそれを達成していません。 – Rpgccv
私は私の.mxmlで投稿を編集します。あなたが私を助けてくれることを願います。再度、感謝します。 – Rpgccv
