データベース、テーブル、ビュー、ストアド プロシージャ、および関数のすべてを削除したいと考えています。リンクを見つけましたが、複雑なデータベースでは機能しません。テーブルの削除に失敗しました。これは、この Web サイトで見つけたスクリプトの独自のバージョンで、微調整したものです。

問題はドロップ制約とドロップ テーブルのみにあります。別のテーブルとの関係を持つテーブルでは常に失敗しました。より複雑なデータベースで動作するようにスクリプトを修正するにはどうすればよいですか?

提供したスクリプトはほぼ完成しています。複雑なケースでより堅牢になるように、いくつかのwhere条件をあちこちで調整しました。このバージョンは、同じ名前でスキーマが異なる2つのオブジェクトの削除をサポートしています。また、場合によってはテーブルを削除できない可能性があるため、データベーストリガーを削除するセクションを追加しました。

私はこれをAdventureWorksデータベースと自分のデータベース（やや非常に複雑です）でテストしました。

私は通常、他の答えと同じアプローチを提案しますが、それはあなたのために働いていないようですので、ここではまったく異なる角度です...

制約を回避するために適切な順序で drop ステートメントを生成するのは複雑ですが、幸いなことに、それを解決するためのスキーマ変更ツールのニッチな市場が存在します。これが私のために働いた1つのアプローチです：

  1. ターゲットと同じバージョンの SQL Server を使用するローカル SQL Server に空のデータベースを作成します。
  2. Red Gate SQL Compareの試用版をダウンロードします(他の同様のベンダー製品も動作する可能性があります) 。
  3. SQL ローカルの空の DB をターゲット DB と比較し、生成されたスクリプトを実行します。

繰り返しますが、Red Gate が唯一のツールだと言っているわけではありません。他のベンダーも同様の機能を主張していますが、私が使用しているのは Red Gate だけです。これをより大きなプロセスまたはスクリプトに埋め込もうとしている場合は、 SDKがあることにも注意してください。
