DATEADD を変更します 日から週へ。したがって、2 つの変更:
dateadd(week, @LastXDays, l_update)
そして
dateadd(week, (@LastXDays + 1), @MaxDate)
この場合、@LastXDays の名前も変更します 変数を @LastXWeeks に .

また、アドバイス:クエリ ヒントを使用しないでください (NOLOCK ) それらの使用法を理解していない場合。この場合、NOLOCK を使用します。 結果に壊滅的な影響を与える可能性があります。
NOLOCK を使い続けるかどうかを決める前に読むべきいくつかの記事を次に示します。
