他の誰かが書いた SQL Server クエリがうまくいきました。私はそれを Postgres に移植する仕事をしています。
どちらのデータベースも、非常に基本的な SQL コマンド以外はよくわかりません (チュートリアルを進めており、どちらの方法でも続行しますが、遅かれ早かれこれを解決したいと思います)。
とにかく、4行目でエラーが発生しています。
エラー: 列 timeloggedtoday.date_logged が存在しません
これは 89 行目あたりのセクション (** でマーク) から来ていると思いますが、構文がどうあるべきかわかりません。ドキュメントから WITH/AS セクションをコピーしようとしましたが、まだ間違いを犯しているか、エラーが別の場所にあります。以下のコードはおそらく繰り返し/余分なコードがたくさんありますが、Postgres 構文に変更したときに他のエラーを簡単に導入できたので、すべてを含めたほうがよいと思いました。
編集：
問題のあるセクションを削除すると、エラーが次のように変わります
エラー: 列 timelogged1daysago.date_logged が存在しません
これは同様のコードの次のバッチであり、一時テーブルの名前を付ける際に構文上のエラーが発生していると思われます (用語は正しいですか?) が、何が問題なのかわかりません。ドキュメントで関連するセクションを見つけるのは困難です... 'With' または 'As' をグーグル検索することは、当然のことながら、役に立ちません。

編集:より簡単なクエリ
このエラーを見つけることを期待して、余分なものをいくつか編集したと思います。いずれにせよ、この短いクエリでは、少なくとも同じエラーが発生するため、デバッグに役立つ可能性があります。
