時間のリストのシーケンス島に基づいて行をクロスオーバー

ちょうど質問のタイトルを書いて私の頭を傷つける！時間のリストのシーケンス島に基づいて行をクロスオーバー

私に同行してください！次のDDL &ダミーデータを参照してください。

は今、私は次のようにダミーデータをレンダリングする必要があります。

あなたが見ることができるように、私は島の開始時刻と終了時刻を抽出する必要があります別個の列として、ブランチに基づいて分割島に注意を払い、& EntryCount。シンプルな数値シーケンスを扱うときにこれを行うための巧妙な解決策を見たことがありますが、このシナリオに合うようにすることはできません。私はあなたが人々にこれにどのようにアプローチするか見ることに興味があります。

つの質問してください。「島」はどういう意味ですか？以前はSQLでこれまで聞いたことがありません。また、[tbl_Example]。[Time]はStartTimeとEndTimeにどのように関係していますか？ – PowerUser
