Selectステートメントから値を取得し、それらをTempテーブルストアドプロシージャに挿入する
これが私のストアドプロシージャです。
テーブルからデータを選択し、それを変数に保存してから、他の変数に挿入します。しかし、私のselect文にはどこにあるのか。その日の値は、forループから取得する必要があります。これは、forループで特定の日のDAYNAME（dateTime）を取得することを意味します。それに基づいて、値をフェッチして挿入ステートメントで使用したいと思います。

問題は、私のselectクエリが複数の行を返し、コードが「ループ」を介してそれらを処理しなかったため、機能せず、エラーが発生したことです。
これは私の新しい手順です...
