具有一个包含1条记录的“订单”表：
+--------+---------+---------+------------+
|ID_ORDER | DESC_ORDER | NUMBER_ORDER |
+----------+---------+--------------------+
| 19 | TEST | TEST |
+----------+---------+--------------------+
和一个带有2条记录的“工人”：
+--------+---------+---------+--
|ID_WORKER | FNAME | LNAME |
+----------+---------+----------
| 25 | ADAM | GAX |
+----------+---------+----------
| 26 | ANDREW | WORM |
+----------+---------+----------
然后我创建了“ status_order”：
+--------+---------+---------+---------+-------------+--------+----------+------------+
| Id_status|ID_WORKER| ID_ORDER| BEGIN_DATE | END_DATE | ORDER_DONE |
+----------+---------+---------+----------+------------+---------+--------------------+
| 30 | 26 | 19 |2019-03-18 06:40:21 |2019-03-18 15:22:32| NO |
+----------+---------+---------+------------+---------+-------------------+-----------+
| 31 | 25 | 19 |2019-03-18 06:51:23 |2019-03-18 15:11:10| NO |
+----------+---------+---------+------------+---------+-------------------+-----------+
| 32 | 26 | 19 |2019-03-20 06:23:32 |2019-03-20 15:33:11| NO |
+----------+---------+---------+------------+---------+-------------------+-----------+
| 33 | 25 | 19 |2019-03-20 06:44:42 |2019-03-20 15:16:22| NO |
+----------+---------+---------+------------+---------+-------------------+-----------+
| 34 | 26 | 19 |2019-03-22 06:44:32 |2019-03-22 11:44:54| YES |
+----------+---------+---------+------------+---------+-------------------+-----------+
| 35 | 25 | 19 |2019-03-22 06:59:22 |2019-03-22 12:33:33| YES |
+----------+---------+---------+------------+---------+-------------------+-----------+
我需要一个MYSQL查询，该查询将正确总结min（begin_date）和max（end_date）之间的日期时间。我在下面尝试了该查询：
SELECT
orders.NUMBER_ORDER,
orders.DESC_ORDER,
SEC_TO_TIME(SUM(TIME_TO_SEC(status_order.END_DATE) -
TIME_TO_SEC(status_order.BEGIN_DATE))) AS 'TOTAL TIME'
FROM status_order
INNER JOIN orders ON orders.ID_ORDER = status_order.ID_ORDER
WHERE orders.NUMBER_ORDER LIKE 'TEST'
得到结果：
+--------+---------+---------+------------+
|DESC_ORDER | NUMBER_ORDER | TOTAL TIME |
+----------+---------+--------------------+
| TEST | TEST | 45:17:50 |
+----------+---------+--------------------+
那总共的时间对我来说太多了。我已经通过以下mysql命令进行了检查：
SELECT workers.FNAME, workers.LNAME, orders.NUMBER_ORDER,
orders.DESC_ORDER,
SEC_TO_TIME(SUM(TIME_TO_SEC(status_order.END_DATE) -
TIME_TO_SEC(status_order.BEGIN_DATE))) AS 'TOTAL TIME'
FROM status_order
INNER JOIN orders ON orders.ID_ORDER = status_order.ID_ORDER
INNER JOIN workers ON workers.ID_WORKER = status_order.ID_WORKER
WHERE orders.NUMBER_ORDER LIKE 'TEST'
GROUP BY workers.ID_WORKER
然后我得到结果：
+--------+---------+---------+-------+------------+------------+
| FNAME | LNAME | NUMBER_ORDER | DESC_ORDER | TOTAL TIME |
+----------+---------+---------------+------------+------------+
| ADAM | GAX | TEST | TEST | 22:25:38 |
+----------+---------+---------------+------------+------------+
| ANDREW | WORM | TEST | TEST | 22:52:12 |
+----------+---------+---------------+------------+------------+
我认为此订单的时差应为21-22小时左右，但我想正确地总结一下时差，例如“ TOTAL TIME”：
+--------+--
|TOTAL TIME|
+--------+--
|22:52:12 |
+--------+--
对不起，我写了那个任务/问题，但对我来说很困难，我不是MYSQL专家。有任何想法吗？我应该写什么样的查询。非常感谢您的帮助！
