多くの副選択を含む行があります
これらを再コード化してサブ選択し、それを単一の行に結合したくなるでしょう (または、単に複数の行を返し、表示コードでフォーマットを実行します)。
ただし、これらの副選択の 1 つを時間に分割するには、次のようなものを使用できます (テストされていません):-
SELECT StartHour, COUNT(*)
FROM
(
SELECT DATE_ADD(@DayStart, INTERVAL i HOUR) AS StartHour
FROM
(
SELECT 0 i UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9
) Sub1
) Sub2
LEFT OUTER JOIN t_container
ON created_timestamp BETWEEN Sub2.StartHour AND DATE_ADD(Sub2.StartHour, INTERVAL 3599 SECOND)
WHERE created_timestamp BETWEEN @DayStart AND @DayEnd
AND container_type_id = '3'
GROUP BY StartHour
これは、開始日に追加することによって時間帯の範囲を考え出し、それを使用してデータに対して左結合を行い (3599 秒を追加して時間帯の終わりを取得します)、グループ化されたカウントを実行します。開始時間の GROUP BY。

テストされていませんが、これを行う1つの方法があります:-
SELECT StartHour,
EndHour,
COUNT(DISTINCT a.id) AS Product1,
COUNT(DISTINCT b.id) AS 'Product 1 EOL 1',
COUNT(DISTINCT c.id) AS 'Product 1 EOL 2',
COUNT(DISTINCT d.id) AS 'Product 2',
COUNT(DISTINCT e.id) AS 'Product 3',
COUNT(DISTINCT f.id) AS 'Product 3 EOL 1',
COUNT(DISTINCT g.id) AS 'Product 3 EOL 2',
COUNT(DISTINCT h.id) AS 'Product 4',
COUNT(DISTINCT i.id) AS 'Product 4 EOL 1',
COUNT(DISTINCT j.id) AS 'Product 4 EOL 2'
FROM
(
SELECT DATE_ADD(@DayStart, INTERVAL i HOUR) AS StartHour, DATE_ADD(DATE_ADD(@DayStart, INTERVAL i HOUR), INTERVAL 3599 SECOND) AS EndHour
FROM
(
SELECT 0 i UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9
) Sub1
) Sub2
LEFT OUTER JOIN t_container a
ON a.created_timestamp BETWEEN Sub2.StartHour AND Sub2.EndHour

LEFT OUTER JOIN t_container g

LEFT OUTER JOIN t_container h
ON h.created_timestamp BETWEEN Sub2.StartHour AND Sub2.EndHour

LEFT OUTER JOIN t_container i
ON i.created_timestamp BETWEEN Sub2.StartHour AND Sub2.EndHour
AND i.container_type_id = '8'

LEFT OUTER JOIN t_container j
ON j.created_timestamp BETWEEN Sub2.StartHour AND Sub2.EndHour
AND j.container_type_id = '8'
AND j.status_id = '6'
GROUP BY StartHour, EndHour
これは、すべての時間帯を取得するために 1 つの副選択を行ってから、テーブルを再び結合してカウントを取得します。ただし、非常に多くの COUNT(DISTINCT )) 型ステートメントを使用すると、パフォーマンスが低下する可能性があります。
おそらく結合を実行して、各副選択で時間範囲を取得し、結合して戻すことが可能である可能性があります。
以前は 2 つの値が / で分割されていた列を 2 つの列に戻したことに注意してください。
おそらくわずかに良い（しかし、おそらくわずかに悪い）:-
