以下の SQL クエリは、教師の空き状況を表示することになっています。可能な予約タイプは、午前、午後、終日、時間単位の 4 つです。午前の予約がある場合、セル内のテキストは PM と表示され、午後の予約がある場合は AM と表示され、終日予約の場合、または午前と午後の両方の予約がある場合は「xxx」と表示されます。これはすべてうまくいきます。
それでは、時間単位の予約に移りましょう。午前 (開始時間 <= 午後 12 時) に 1 つ、午後 (終了時間 > 午後 12 時) に 1 つ、毎日 2 つの時間単位の予約しかないと想定しても問題ありません。つまり、'xxx' を表示する必要があります。しかし、私はこれを表示するのに本当に苦労しています。

表の列:

9386 Tuesday AM

9763 Tuesday AM
9763 Wednesday XXX
9927 Monday PM
9927 Tuesday AM
9927 Wednesday XXX
10358 Monday PM
10358 Monday AM
ここでわかるように、最後の 2 行をマージして、ステータス列に XXX として表示する必要があります。
以下のスクリーンショットに例を示します。黄色で強調表示されているのは、PM を示しています。ただし、2 つの時間単位の予約 (BookingDuration ID 3) があり、1 つは午前 10:00 ～ 11:00、もう 1 つは 14:00 ～ 15:00 です。したがって、これは PM/AM ではなく XXX を表示する必要があります。
これが理にかなっていることを願っています！
