わかりました.. あきらめて、旧友の xpcmdshell に戻りました。フルネームを含むページを読み込めないことが多いため、この応答とそのコード全体で、アンダースコア (_) が xpcmdshell に暗示されます。
まず、私が試した中でうまくいかなかったことが 3 つだけあります (他のすべてを思い出すことはできません)。
- NOCOUNTをオンに設定
- 一時テーブルのない任意の SP で機能しますが、2500 以上のほとんどがそれらを利用するために調べているため、これは実現不可能です。
- ノーオペレーション
- No Op を動的に作成する手順を作成しましたが、実装時に、SQL がネスト ループに陥るのを回避する方法を見つけることができませんでした。
- bcp クエリアウト
それで、頭をぶつけてグーグルで調べた後、xpcmdshellに戻りました。次のスクリプト (プロシージャに変換します) は、SP exec ステートメントとそれを実行するデータベースを取得し、xpcmdshell sqlquery コマンドをファイルにフォーマットし、ファイルを実行して、その出力を一時テーブルに挿入します。次に、これらの結果の列ヘッダーを別の一時テーブルに抽出します。
