sql-server-2008 - テーブル継承で配布されるSQLINSERTINTOステートメントの構文は何ですか？

Question

私は初心者で、EntityFramework4.1のモデリングツールの実験を始めたばかりです。

写真は私のデータベースの図を示しており、さらにその下には、データベース（SQL Server 2008）を作成するための自動生成されたスクリプトがあります。

ここに画像の説明を入力してください

私の質問は、Entity Framework自体ではなく、単純なSQL構文です。

私のモデルでは、CameraエンティティはUnitから継承しています。次のようなカメラテーブルINSERTを作成したいと思います。

INSERT INTO UnitSet_Camera
       (Login,
        Password,
        URL)
 VALUES
       ('myLoginName'
       ,'myPassword'
       ,'http://foo.bar:007');

また、 Cameraエンティティに「Name」を指定する必要があるため（テーブルUnitとそのプロパティ「Name」からの継承のため）、これが不完全であることもわかっています。

完全なSQLステートメントは任意のCameraエンティティをどのINSERTように探す必要がありますか？

継承であるため、2つのテーブルがあります。UnitSetには、派生クラスで参照されるIDENTITYがあります。基本的にこれを行う必要があります：

INSERT INTO dbo.UnitSet (Name) VALUES ('The Name');
INSERT INTO UnitSet_Camera
       (Login,
        Password,
        URL,
        Id)
 VALUES
       ('myLoginName'
       ,'myPassword'
       ,'http://foo.bar:007'
       ,SCOPE_IDENTITY());

ただし、1つのステートメントでそれを実行するOUTPUTのような他の機能があります。または、カメラのすべてのプロパティを公開するビューを作成し、トリガーを使用して更新可能にすることもできます。

しかし、この種の操作を行うためにORMを実行することを明らかに決定したのに、なぜSQLを介してこれを実行したいのか疑問に思います。

sql-server-2008 - テーブル継承で配布されるSQLINSERTINTOステートメントの構文は何ですか？
