Question

在mysql数据库中，我创建了请假表：

+--------+---------+---------+-------------+---------+--------------------------
|ID_LEAVE|ID_WORKER| FNAME | LNAME | BEGIN_DATE         | END_DATE             | 
+--------+---------+---------+---------+------------+--------------------+------
| 1      |   1     | ALAN  | MAX   |2019-03-19 07:00:00 |2019-03-20 15:00:00   | 
| 2      |   1     | ALAN  | MAX   |2019-03-21 07:00:00 |2019-03-21 15:00:00   |
+--------+---------+---------+----------------------+---------------------------

“工人表”

+----------+---------+---------+
|ID_WORKER |  FNAME  | LNAME   |
+----------+---------+----------
| 1        |  ALAN   |  MAX    |
| 2        |  MARK   |  DARK   |
+----------+---------+---------+

“订单”表：

+----------+--------------+---------------+
|ID_ORDER  |  DESC_ORDER  | NUMBER_ORDER  |
+----------+--------------+---------------+
| 20       |  TEST        |  TEST         |
+----------+--------------+---------------+

“订单状态”表：

+----------+---------+---------+---------------------+-------------------+------------+
| Id_status|ID_WORKER| ID_ORDER| BEGIN_DATE          | END_DATE          | ORDER_DONE |
+----------+---------+---------+----------+------------+---------+--------------------+
| 30       |   1     |    20   |2019-03-18 06:50:35  |2019-03-18 15:21:32|  NO        |
| 31       |   1     |    20   |2019-03-20 06:44:12  |2019-03-20 15:11:23|  NO        |
| 32       |   1     |    20   |2019-03-22 06:50:20  |2019-03-22 12:22:33|  YES       |
| 33       |   2     |    20   |2019-03-18 06:45:11  |2019-03-18 15:14:45|  NO        |
| 34       |   2     |    20   |2019-03-20 06:50:22  |2019-03-20 15:10:32|  NO        |
| 35       |   2     |    20   |2019-03-22 06:54:11  |2019-03-22 11:23:45|  YES       |
+----------+---------+---------+------------+---------+-------------------+-----------+

我做了什么：

我可以在订单上总结每个工人（在order_status表中）的“总时间”，包括从Leave表中总结“离开时间”，也可以（部分地）总结“ Order time” +“ leave time”。我也已正确选择了彼此的工人订单（LNAME，FNAME）订单（DESC_ORDER和NUMBER_ORDER）和“ TOTAL TIME”。我在下面编写了mysql命令：

SELECT workers.fname, 
       workers.lname, 
       order_statusAgg.number_order,
       workers.id_worker,
       order_statusAgg.desc_order, 
       SEC_TO_TIME(SUM(order_statusAgg.stime)) AS 'ORDER TIME', 
       IFNULL(SEC_TO_TIME(SUM(leaveAgg.vtime)),'00:00:00') AS 'LEAVE TIME'
       time_format(SEC_TO_TIME(SUM(order_statusAgg.stime)) +  IFNULL(SEC_TO_TIME(SUM(leaveAgg.vtime)),'00:00:00'), '%H:%i:%s') AS 'TOTAL TIME'
FROM   workers 
LEFT JOIN (
SELECT leave.id_worker, time_format(SUM((datediff(leave.end_date, leave.begin_date) + 1) * (time(leave.end_date) - time(leave.begin_date))), '%H:%i:%s') AS vtime 
FROM leave
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

然后我得到结果：

+---------+---------+---------------+------------+------------+--------------+-----------+
|  FNAME  | LNAME   |  NUMBER_ORDER | DESC_ORDER | ORDER TIME | LEAVE_TIME   | TOTAL TIME|
+---------+---------+---------------+------------+------------+--------------+-----------+
|  ALAN   |  MARK   | TEST          | TEST       | 22:30:21   |   24:00:00   |  22:30:45 |
+---------+---------+---------------+------------+------------+--------------+-----------+
|  MARK   |  GREEN  | TEST          | TEST       | 21:19:18   |   00:00:00   |  21:19:18 |
+---------+---------+---------------+------------+------------+--------------+-----------+

但是另一方面，此查询仅增加了24秒而不是24小时因为可能是这一行查询：

time_format(SEC_TO_TIME(SUM(order_statusAgg.stime)) +  IFNULL(SEC_TO_TIME(SUM(leaveAgg.vtime)),'00:00:00'), '%H:%i:%s') AS 'TOTAL TIME'

应为：

+---------+---------+---------------+------------+------------+--------------+-----------+
|  FNAME  | LNAME   |  NUMBER_ORDER | DESC_ORDER | ORDER TIME | LEAVE_TIME   | TOTAL TIME|
+---------+---------+---------------+------------+------------+--------------+-----------+
|  ALAN   |  MARK   | TEST          | TEST       | 22:30:21   |   24:00:00   |  46:30:21 |
+---------+---------+---------------+------------+------------+--------------+-----------+
|  MARK   |  GREEN  | TEST          | TEST       | 21:19:18   |   00:00:00   |  21:19:18 |
+---------+---------+---------------+------------+------------+--------------+-----------+

例如由于：测试订单的ALAN MARK：总时间=订单时间+离开时间总时间= 22:30:21 + 24:00:00 = 46:30:21

有人可以显示我应该编写哪种查询吗？有任何想法吗？谢谢您的帮助或建议！

Answer 1

您所说的总时间=订单时间+离开时间总时间= 22:30:21 + 24:00:00 = 46:30:21

解决这个问题的一种方法是使用addtime函数

ADDTIME('22:30:21',IFNULL('24:00:00','00:00:00')) as `TOTAL TIME`

如何正确地概括为“订购时间” +“休假时间”-mysql（添加小时数而不是秒数）
