【问题描述】：

在 mysql 数据库中我创建了“离开”表：

CREATE TABLE `leave` ( 
`ID_LEAVE` int(11) NOT NULL,
`ID_WORKER` int(11) NOT NULL,
`BEGIN_DATE` datetime DEFAULT NULL,
`END_DATE` datetime DEFAULT NULL
);

INSERT INTO `leave` 
(`ID_LEAVE`, `ID_WORKER`, `BEGIN_DATE`, `END_DATE`) VALUES
(3, 26, '2019-03-20 07:00:00', '2019-03-21 15:00:00'),
(4, 22, '2019-03-20 07:00:00', '2019-03-20 15:00:00');

“工人”表：

CREATE TABLE `workers` (
`ID_WORKER` int(11) NOT NULL,
`FNAME` varchar(20) NOT NULL,
`LNAME` varchar(20) NOT NULL
);

INSERT INTO `workers` (`ID_WORKER`, `FNAME`, `LNAME`) VALUES
(22, 'ALAN', 'FAST'),
(23, 'LEON', 'SPEED'),
(24, 'ADAM', 'GREEN'),
(25, 'DAVID', 'BUCS'),
(26, 'JACK', 'FAR'),
(27, 'ADAM', 'GAX'),
(28, 'ANDREW', 'WORM');

“订单”表：

CREATE TABLE `orders` (
`ID_ORDER` int(11) NOT NULL,
`DESC_ORDER` varchar(50) NOT NULL,
`NUMBER_ORDER` varchar(30) NOT NULL
);

INSERT INTO `orders` (`ID_ORDER`, `DESC_ORDER`, `NUMBER_ORDER`) VALUES
(19, 'TEST', 'TEST'),
(20, 'TEST2', 'TEST2'),
(21, 'TEST3', 'TEST3'),
(22, 'TEST4', 'TEST4');

“Order_status”表（对不起，这不是按顺序排列的）：

CREATE TABLE `order_status` (
`ID_STATUS` int(11) NOT NULL,
`ID_ORDER` int(11) NOT NULL,
`ID_WORKER` int(11) NOT NULL,
`BEGIN_DATE` datetime NOT NULL,
`END_DATE` datetime NOT NULL,
`ORDER_DONE` varchar(50) DEFAULT NULL
) ;

INSERT INTO `order_status` (`ID_STATUS`, `ID_ORDER`, `ID_WORKER`, `BEGIN_DATE`, `END_DATE`, `ORDER_DONE`) VALUES
(30, 19, 26, '2019-03-18 06:40:21', '2019-03-18 15:22:32', 'NO'),

我做了什么：

我可以总结其他工人的“订购时间”。我也正确地选择了工人（LNAME，FNAME）订单（DESC_ORDER 和 NUMBER_ORDER）和“TOTAL TIME”。我在下面写了mysql命令：

SELECT workers.FNAME, 
workers.LNAME, 
order_statusAgg.NUMBER_ORDER,
order_statusAgg.DESC_ORDER, 
SEC_TO_TIME(SUM(order_statusAgg.stime)) AS 'ORDER TIME'
FROM workers
LEFT JOIN (
SELECT order_status.ID_WORKER, orders.NUMBER_ORDER, orders.DESC_ORDER, 
SUM((TIME_TO_SEC(order_status.END_DATE) - TIME_TO_SEC(order_status.BEGIN_DATE))) AS stime 
FROM order_status INNER JOIN orders
ON orders.ID_ORDER = order_status.ID_ORDER
GROUP BY order_status.ID_WORKER) order_statusAgg
ON workers.ID_WORKER = order_statusAgg.ID_WORKER
WHERE order_statusAgg.NUMBER_ORDER LIKE 'TEST'
GROUP BY workers.ID_WORKER;

然后我得到：

+---------+---------+---------------+------------+------------+
|  FNAME  | LNAME   |  NUMBER_ORDER | DESC_ORDER | ORDER TIME | 
+---------+---------+---------------+------------+------------+
|  DAVID  |  BUCS   | TEST          | TEST       | 22:30:21   |
+---------+---------+---------------+------------+------------+
|  JACK   |  FAR    | TEST          | TEST       | 21:19:18   |
+---------+---------+---------------+------------+------------+

我分析了 2 天（2019 年 3 月 20 日和 2019 年 3 月 21 日）。照片如下：

现在我需要 mysql 查询来正确汇总休假时间，并按如下所述的模式进行：

例如 ID_WORKER = 26 的休假时间（他有订单“TEST”）

                    '08:31:40'                                      '08:31:40'
(-------------------------------------------------) * 8:00:00 =  (--------------) * 8:00:00 = 2:00:16
 '08:31:40' + '08:37:00' + '08:53:03' + '08:29:01'                  '34:30:44'

我已经尝试过：我已经通过下面的 mysql 查询尝试了总休假时间：

SELECT workers.FNAME, 
workers.LNAME, 
order_statusAgg.NUMBER_ORDER,
order_statusAgg.DESC_ORDER, 
SEC_TO_TIME(SUM(order_statusAgg.stime)) AS 'ORDER TIME', 
IFNULL(SEC_TO_TIME(SUM(leaveAgg.ltime)),'00:00:00') AS 'LEAVE TIME'
FROM workers
LEFT JOIN (SELECT leave.ID_WORKER, SUM((datediff(leave.BEGIN_DATE, leave.END_DATE) + 1) * (time_to_sec(time(leave.END_DATE)) - time_to_sec(time(leave.BEGIN_DATE)))) AS ltime FROM leave
LEFT JOIN
(SELECT ID_WORKER, MIN(BEGIN_DATE) AS 'MIN_BEGIN_DATE', MAX(END_DATE) AS 'MAX_END_DATE' 
FROM order_status GROUP BY ID_WORKER) ordstat ON 
leave.ID_WORKER = ordstat.ID_WORKER 
WHERE leave.END_DATE <= MAX_END_DATE AND leave.BEGIN_DATE >= MIN_BEGIN_DATE GROUP BY leave.ID_WORKER) leaveAgg
ON leaveAgg.ID_WORKER = workers.ID_WORKER
LEFT JOIN (
SELECT order_status.ID_WORKER, orders.NUMBER_ORDER, orders.DESC_ORDER, 
SUM((TIME_TO_SEC(order_status.END_DATE) - TIME_TO_SEC(order_status.BEGIN_DATE))) AS stime 
FROM order_status INNER JOIN orders
ON orders.ID_ORDER = order_status.ID_ORDER
GROUP BY order_status.ID_WORKER) order_statusAgg
ON workers.ID_WORKER = order_statusAgg.ID_WORKER
WHERE order_statusAgg.NUMBER_ORDER LIKE 'TEST'
GROUP BY workers.ID_WORKER;

但恐怕这还不够，因为它只添加了例如：

22:30:21 + 8:00:00 = 30:30:21

我想得到那个结果：

22:30:21 + 2:00:16 = 24:30:37

注意！如果有人得到 2 天或更长时间的休假，我不能这样做：

                    '08:31:40'                                      
(-------------------------------------------------) * 16:00:00 
 '08:31:40' + '08:37:00' + '08:53:03' + '08:29:01'

我必须像我解释的那个例子那样每天分析。

我知道这是一个更难的问题，我找不到任何线索来解决它。有人可以请我应该更改或添加什么。提前感谢您的任何帮助或建议。

@JimJimson 是的。我仍在寻找解决方案。
太好了，请看下面的答案。

【解决方案1】：

您的 order_status 表中似乎有一些额外的数据，因为我得到了一些额外的行。但是过滤掉这些并运行一天我得到了一个结果。我在电子表格中仔细检查了结果，它似乎是正确的：

(08:31:40 / 34:30:44) * 08:00:00 = 01:58:36.3194

无论如何，这是查询，您正在寻找window functions 来解决您的问题：

SELECT *,
SEC_TO_TIME((d.ORDER_TIME / d.DAILY_TOTAL) * 28800) as 'LEAVE TIME'
FROM
(
SELECT  os.*,
        o.NUMBER_ORDER,
        ((TIME_TO_SEC(os.END_DATE) - TIME_TO_SEC(os.BEGIN_DATE))) AS 'ORDER_TIME',
        (SUM(TIME_TO_SEC(os.END_DATE) - TIME_TO_SEC(os.BEGIN_DATE)) OVER (PARTITION BY CAST(os.END_DATE AS DATE) ORDER BY o.ID_ORDER ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING)) as 'DAILY_TOTAL'
FROM order_status os
    INNER JOIN orders o ON o.ID_ORDER = os.ID_ORDER
WHERE   (
        CAST(os.BEGIN_DATE AS DATE) = '2019-03-20' OR
        CAST(os.END_DATE AS DATE) = '2019-03-20'
        )
        AND NOT (
                    os.ID_STATUS = 32 AND
                    os.ID_ORDER = 19 AND
                    os.ID_WORKER = 26)
) d
