以下のコードは、ソースシステムの温度（人が病院にいるときの気温）を含むグループ化されたデータのサンプルです。SQLクエリで不良なデータの品質を処理する方法
明らかにデータは恐ろしいですが、私たちがUOM（計量単位）フィールドを持っているので何らかの形でこのデータをINTに変換できるかどうか疑問に思っています。
データの問題：
88度摂氏 3635が36.35 0.368が36.8 37.3だろうだろう明らかに華氏ではありません。 37.3 .37.7は37.7 377が37.7 .3.8は
38は、私は他のバリエーションだけで正確な情報に仮定を作ることができないとして、公正であることを、無効なデータを除外すべきだと思うだろうだろうだろうだろう。

これは、 'CASE'、' LIKE'、 'PATINDEX'などを使用して、多くのサブ問題に分解されたT-SQLで作成したルールの実装にまで及んでいます。コンピュータの利益のために慎重に細かくコード化しなければならない。より複雑なケースでは、T-SQLの文字列操作がそれほど進んでいないため、正規表現を使用できるクライアント側のクレンジングが必要な場合があります。 –
