はnu.new_uplift列を取り、ことを各行に適用されますクエリを記述で現在表示されている値で表示されています（混乱する文章、別の方法で説明する必要がある場合は教えてください）。私はCTEを使用してこれを行うことができると思ったが、私はサブクエリを使用しているので可能だとは思わない。そのことを念頭に置いて - 私はここで何を利用すべきですか？

Answer 1

非常に広い意味で、UPDATE... from...がここで動作するはずです。 1つの可能なテンプレート：

SELECT文と同様に、「OtherTableName」はほとんどの表のosサブクエリで置き換えることができます。

ここでは、更新するテーブルを選択し、「from」句に最初にリストされたものとして配置し、ORDER BY句なしのモンスターサブクエリに適切に結合します。
