重複の可能性:
毎週、過去 6 週間の日曜日の日付を SQL でグループ化する方法は?

週数をカウントする必要があります。正常に動作しますが、[34]、[35]、[36]、[37]、[38]、[39] の週番号がわかりません。週番号はランタイムのみを認識します。たとえば、1 年には合計 52 週間が含まれます。@Bluefeet の助けを借りてこのクエリを取得しました。彼は同じスタックオーバーフローにクエリを投稿しました。間のフィールドで開始日と終了日を変更すると、機能しません。以下のクエリでweeknoをハードコーディングしたためです。年内のフィールド間の日付が何であれ、解決策を教えてください。

任意の日付値を渡して基準を満たすデータを取得できるようにする場合は、このタイプのPIVOT場合、次のような動的 SQL ソリューションを使用する必要があります。

    @colsRollup AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX),

    @EndDate DateTime
