mysql - SQL查询每小时报告？

Question

我有点难打败我。我们有一个生产各种产品的仓库，我们使用以下查询发送每日生产报告，但我希望每小时对其进行排序:

(我将查询缩减为只有少数产品，因为它很重要:

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'

我想要实现的是运行上述报告，但输出以 1 小时为增量。

如有任何帮助，我们将不胜感激。

请看下面的“预期输出示例”

时间 |产品 1 |产品 1 停产 |产品 2 |产品 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

你有一行包含很多子选择

我很想重新编码这些子选择，然后将它们连接成一行(或者只返回多行并在显示代码中进行格式化)。

然而，要将这些子选择之一拆分为几个小时，您可以使用类似这样的东西(未测试):-

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

这会通过添加到开始日期来得出一系列小时时间段，然后使用它对您的数据进行左连接(添加 3599 秒以获得小时时间段的结束)，然后进行分组计数，在开始时间进行 GROUP BY。

编辑

未测试，但这是一种方法:-

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

这是执行 1 个子选择以获取所有小时时间段，然后重新连接表以获取计数。然而，使用这么多 COUNT(DISTINCT )) 类型的语句可能不会执行得那么好。

可能可以进行连接以获取每个子选择中的小时范围，然后再连接回去，这可能会更好。

请注意，我已经为以前有 2 个值的列带回了 2 列，这些列被/分隔。

可能稍微好一点(但也可能稍微差一点):-

SELECT Product1.rec_cnt AS Product1,
        CONCAT(Product1EOL1.rec_cnt, ' / ', Product1EOL2.rec_cnt) AS 'Product 1 EOL',

        Product3.rec_cnt AS 'Product 3',
        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'
