[KNIME] Column Filterの使い方

Last updated at Posted at 2021-04-07

Column Filterにおいて、ある特定のカラムだけをIncludeして通したいときは下部にあるEnforce inclusionにチェックを入れます。

例えば、Purposeカラムだけを通したいときは以下のようにします。

もし、Enforce inclusionにチェックを入れない場合は、入力データのカラム名が変更になったときに、ワークフローの作成に使用したテーブルには存在しなかった名前のカラムがInclude内に入ってきてしまいます。

例)Enforce inclusionにチェックを入れていないので、Purpose以外のデータまでIncludeに入ってきてしまう。
