SQL查詢每小時報告？

Question

我有一個艱難的人在這里毆打我。 我們有一個生產各種產品的生產倉庫，我們使用以下查詢發送每日生產報告，但我希望每小時進行一次排序：

（我將查詢精簡為僅幾個產品，因為它相當大：

SET

@DayStart = '2013-10-24 07:00:00',
@DayEnd = '2013-10-24 16:00:00';

SELECT 
(SELECT COUNT(*) FROM t_container
    WHERE created_timestamp BETWEEN @DayStart AND @DayEnd
    AND container_type_id = '3'

) AS Product1,

(SELECT CONCAT (
    (SELECT COUNT(*) FROM t_container
    WHERE created_timestamp BETWEEN @DayStart AND @DayEnd
    AND container_type_id = '10'
    AND status_id = '4'
    ) , ' / ' ,
    (SELECT COUNT(*) FROM t_container
    WHERE created_timestamp BETWEEN @DayStart AND @DayEnd
    AND container_type_id = '10'
    AND status_id = '6'
    ))
) AS 'Product 1 EOL',

(SELECT COUNT(*) FROM t_container
    WHERE created_timestamp BETWEEN @DayStart AND @DayEnd
    AND container_type_id = '2'
    ) AS 'Product 2',

(SELECT COUNT(*) FROM t_container
    WHERE created_timestamp BETWEEN @DayStart AND @DayEnd
    AND container_type_id = '6'
    ) AS 'Product 3',

(SELECT CONCAT (
    (SELECT COUNT(*) FROM t_container
    WHERE created_timestamp BETWEEN @DayStart AND @DayEnd
    AND container_type_id = '9'
    AND status_id = '4'
    ) , ' / ' ,
    (SELECT COUNT(*) FROM t_container
    WHERE created_timestamp BETWEEN @DayStart AND @DayEnd
    AND container_type_id = '9'
    AND status_id = '6'
    ))
) AS 'Product 3 EOL',

(SELECT COUNT(*) FROM t_container
    WHERE created_timestamp BETWEEN @DayStart AND @DayEnd
    AND container_type_id = '4'
) AS 'Product 4',

(SELECT CONCAT (
    (SELECT COUNT(*) FROM t_container
    WHERE created_timestamp BETWEEN @DayStart AND @DayEnd
    AND container_type_id = '8'
    AND status_id = '4'
    ) , ' / ' ,
    (SELECT COUNT(*) FROM t_container
    WHERE created_timestamp BETWEEN @DayStart AND @DayEnd
    AND container_type_id = '8'
    AND status_id = '6'
    ))
) AS 'Product 4 EOL'

我想實現的是運行以上報告，但輸出以1小時為增量。

任何幫助將不勝感激。

請參見下面的“預期輸出示例”

時間| 產品1 | 產品1停產| 產品2 | 產品3
07:00 | 12345 | 1/1 | 1568789 | 1/1
08:00 | 12345 | 1/1 | 1568789 | 1/1
09:00 | 12345 | 1/1 | 1568789 | 1/1

Answer 1

您有一行包含很多子選擇

我很想將它們重新編碼為子選擇，然后再將它們加入到單行中（或僅返回多行並按照顯示代碼的格式進行格式化）。

但是，要將這些子選擇之一分成幾個小時，您可以使用類似以下內容（未經測試）：-

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

通過添加開始日期來設置小時范圍，然后使用該范圍對您的數據進行左連接（添加3599秒以獲取小時結束時間段），並進行分組計數，在開始時間的GROUP BY。

編輯

未經測試，但這是一種實現方法：-

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
AND a.container_type_id = '3'
LEFT OUTER JOIN t_container b
ON b.created_timestamp BETWEEN Sub2.StartHour AND Sub2.EndHour
AND b.container_type_id = '10'
AND b.status_id = '4'
LEFT OUTER JOIN t_container c
ON c.created_timestamp BETWEEN Sub2.StartHour AND Sub2.EndHour
AND c.container_type_id = '10'
AND c.status_id = '6'
LEFT OUTER JOIN t_container d
ON d.created_timestamp BETWEEN Sub2.StartHour AND Sub2.EndHour
AND d.container_type_id = '2'
LEFT OUTER JOIN t_container e
ON e.created_timestamp BETWEEN Sub2.StartHour AND Sub2.EndHour
AND e.container_type_id = '6'
LEFT OUTER JOIN t_container f
ON f.created_timestamp BETWEEN Sub2.StartHour AND Sub2.EndHour
AND f.container_type_id = '9'
AND f.status_id = '4'
LEFT OUTER JOIN t_container g
ON g.created_timestamp BETWEEN Sub2.StartHour AND Sub2.EndHour
AND g.container_type_id = '9'
AND g.status_id = '6'
LEFT OUTER JOIN t_container h
ON h.created_timestamp BETWEEN Sub2.StartHour AND Sub2.EndHour
AND h.container_type_id = '4'
LEFT OUTER JOIN t_container i
ON i.created_timestamp BETWEEN Sub2.StartHour AND Sub2.EndHour
AND i.container_type_id = '8'
AND i.status_id = '4'
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

這樣做是進行1次子選擇以獲取所有小時時間段，然后將表重新連接以獲取計數。 但是，使用這么多的COUNT（DISTINCT））類型的語句可能效果不佳。

可能有可能進行聯接以獲取每個子選擇中的小時范圍，然后再聯接回去，這可能更好。

請注意，我為以前有2個值（用/分隔）的列帶回了2列。

可能稍好（但也可能稍差）：-

        CONCAT(Product1EOL1.rec_cnt, ' / ', Product1EOL2.rec_cnt) AS 'Product 1 EOL',

        CONCAT(Product3EOL1.rec_cnt, ' / ', Product3EOL2.rec_cnt) AS 'Product 3 EOL',
        Product4.rec_cnt AS 'Product 4',
        CONCAT(Product4EOL1.rec_cnt, ' / ', Product4EOL2.rec_cnt) AS 'Product 4 EOL'
