SQLクエリアシスタントの編集/編集

Question

最初の要求日から最初の完了日までの経過時間を計算する以下のクエリがあります。 しかし、以下の例では、2017-02-06で作成された要求日が2017-02-02（期限付き）です。

私は、要求された日付を選択し、それが0 推論であるべきとき

だから今、それは1を返し FIRST 作成日から完了するまでの経過どのくらいの時間を計算するクエリを編集したいです最初に作成された日付が2017-02-03で、同じ日にリクエストされ完了したためです。2017-02-03

大変助けになりました！

Answer 1

は、私が最初に作成さDATEから

変更これを完了するまでの経過どのくらいの時間要求された日付を選択して、 を計算するクエリを編集したいですこれまで：

     ,MIN(case 
           when SN_TYPE = 'Re-Activattion' 
           then Created_Date 
           else null 
          end
