データベース内のすべてのインデックスのスクリプトを生成する
データベース内のすべてのインデックスのスクリプトを生成したい（Create Index）。
インデックススクリプトとテーブル作成スクリプトは必要ありません。 SQL Server（2005または2008）でどのように生成できますか。クラスター化インデックスと非クラスター化インデックスには個別のスクリプトが必要です。

探しているもの（ソート、フィルタリング）が正確ではない場合、最初から始めるよりも編集する方が簡単だと確信しています。
最初の例のわずかに修正された（2019）コードは次のとおりです。

データベース内のすべてのインデックスをスクリプト化するためのTSQL
これはスクリプトアウトします：
- クラスター化インデックスと非クラスター化インデックス（フィルター選択されたインデックスを含む）
- インデックスが作成されるファイルグループ（パーティション化されていない場合）
- インデックスが作成されるパーティションスキーム（パーティション化されている場合）
- インデックスが圧縮されている場合の圧縮設定-テーブルがパーティション化されている場合はパーティションごと
- クラスタ化インデックスを持たないテーブルの場合、ヒープであることを示すコメント付きの結果の行が引き続き取得されます

私はこれのための方法を提案するかもしれません：
- インデックス（インデックス）なしでテーブルのスクリプトを作成します。
- 他のデータベースにテーブルを再作成します
- sql comparerツールを使用して、2つのデータベースに基づいてインデックス作成スクリプトを作成します（おそらく、そのようなツールがある場合、そのツールには既にこの機能が備わっている可能性があります）。
