62 DBMS_DEVELOPER
パッケージDBMS_DEVELOPERには、データベース・オブジェクトに関する情報を取得するための開発者にわかりやすいシンプルなメソッドが用意されています。
この章のトピックは、次のとおりです:
62.1 DBMS_DEVELOPERの概要
パッケージDBMS_DEVELOPERには、データベース・オブジェクトに関する情報を取得するためのサブプログラムが用意されています。
DBMS_DEVELOPERパッケージには、データベース・オブジェクトの関連情報を取得するための簡単なメソッドが用意されています。このパッケージは、開発者ツールや開発者がデータベース内のオブジェクト、そのシェイプ、構造などの情報を取得する場合に役立ちます。
パフォーマンスに関しては、DBMS_DEVELOPERパッケージは数ミリ秒以内に情報を取得します。
62.2 DBMS_DEVELOPERのセキュリティ
この項では、DBMS_DEVELOPERパッケージに関連するセキュリティ制限を示します。
このファンクションは実行者の権限で実行されます。データベース・オブジェクトのメタデータへのアクセスは、オブジェクトを「表示」する権限がある場合にのみ許可されます。そのような認可がない場合、エラーが発生し、メタデータは取得されません。
必要な権限の要約を次に示します:
- 表およびビュー: 表またはビューに対するSELECT権限またはREAD権限が必要です。
- 索引: 索引が定義される表に対するSELECT権限またはREAD権限が必要です。
- シノニム: シノニムおよび基礎となるオブジェクトに対するSELECT権限またはREAD権限が必要です。
自分のスキーマ内のオブジェクトを記述する場合は、追加の権限は必要ありません。ただし、別のスキーマのオブジェクトを記述する場合は、それらのオブジェクトに対するSELECT権限が必要です。
DBAであるか、SELECT ANY TABLE、READ ANY TABLEおよびSELECT ANY VIEWシステム権限を持っている場合は、明示的に付与しなくても、データベース内の任意の表、索引またはビューに対してDBMS_DEVELOPER.GET_METADATAをコールできます。
62.3 DBMS_DEVELOPERサブプログラムの要約
この表は、DBMS_DEVELOPERサブプログラムおよび簡単な説明を示しています。
次の表に、DBMS_DEVELOPERパッケージのサブプログラムとその簡単な説明を示します。
| サブプログラム | 説明 |
GET_METADATA |
このファンクションは、オブジェクトに関する情報(name、object_type、schema、etagなど)を受け取り、JSON形式のテキスト出力を含む対応するメタデータをCLOBに生成します。出力に生成する必要がある情報のレベルは、入力パラメータ(level)で指定できます。
|
62.3.1 GET_METADATAファンクション
この項では、GET_METADATAファンクションの構文、入力および出力形式について説明します。
このファンクションは、オブジェクトに関する情報を受け取り、対応するメタデータをJSON形式のテキスト出力を含むCLOBとして生成します。
構文
DBMS_DEVELOPER.GET_METADATA (
name IN VARCHAR2,
schema IN VARCHAR2 DEFAULT NULL,
object_type IN VARCHAR2 DEFAULT NULL,
level IN VARCHAR2 DEFAULT 'TYPICAL'
etag IN RAW DEFAULT NULL)
RETURN CLOB;表62-1 入力構成のフィールド
| フィールド | 値 |
|---|---|
|
|
オブジェクト名。オブジェクト名のシノニムも指定できます。大文字と小文字が区別され、データ・ディクショナリに示されているとおりに指定する必要があります。 |
|
|
スキーマ名。デフォルトは現行ユーザーです。大文字と小文字が区別され、データ・ディクショナリに示されているとおりに指定する必要があります。 |
|
|
取り出すオブジェクトのタイプ。これはオプションです。名前解決は、 サポートされている値: |
|
|
詳細のレベル。デフォルトは サポートされる値:
|
|
|
特定のバージョンのドキュメントの一意の識別子。この
|
GET_METADATAファンクションは、JSONスキーマを返しません。かわりに、JSONドキュメントを返します。取得するメタデータのレベルに応じて、GET_METADATAファンクションに適切なパラメータを使用して、目的のメタデータJSONドキュメントを取得できます。
アプリケーションに必要なスキーマを理解するには、「様々なオブジェクトおよびサブオブジェクト・タイプのJSONスキーマ」を参照してください。

62.3.1.1 様々なオブジェクトおよびサブオブジェクト・タイプのJSONスキーマ
この項では、様々なオブジェクト・タイプ、サブオブジェクト・タイプおよびレベルで可能な各種スキーマの概要を示します。
このJSONスキーマは、アプリケーションでリファレンスとして使用して、返されたJSONドキュメントを解析できます。特定のバージョンのデータベース・プログラムをプログラミングする場合は、そのデータベース・バージョンに対する特定のバージョンのJSONスキーマを使用すると、そのスキーマは常に同じになります。ただし、別のリリースにアップグレードまたはダウングレードする場合は、別のスキーマ・バージョンを使用するため、その正しいスキーマを使用する必要があります。スキーマが変更された場合は、$idフィールドのバージョン番号が変更されます。今後オラクルがJSONスキーマの改訂を予定している場合でも、アプリケーションはこの数値に依拠できます。既存のバージョンは変更されないため、アプリケーションは引き続き完全に機能し、更新の影響を受けません。
