问题描述
我有要在其中插入数据的表。我有一个源类型，它告诉数据来自哪个源。源有两种类型：1.包含WAPDA，太阳能和发电机作为源的电源；以及2.实际用户的计量表。转动仪表时，其数据会与日期和时间一起保存，同步仪表数据也会与日期和时间一起保存。信号源和同步仪表的日期和时间将相同，唯一的区别是信号源的类型
始终应该将同步仪表设为turned on，而一次只能使用一个turned on。这是一些示例数据，以及DB Fiddle相同的数据：

我要执行以下操作
根据日期和时间取出特定来源的所有同步表，持续24小时。也就是说，如果从turned on到2020-08-31 14:00:00的来源是2020-08-31 15:00:00，那么我想检查一下在这段时间内有多少个同步仪表数据可用。例如
msn | cust_id | MAX(kwh_t)| data_date_time(start) | data_date_time(end) | source
============================================================================================
00209703| | 300 | 2020-08-31 14:00:00 | 2020-08-31 14:30:00 | WAPDA
00209706|37010114713| 200 | 2020-08-31 14:00:00 | 2020-08-31 14:30:00 | Sync Meter
00209707|37010114710| 100 | 2020-08-31 14:00:00 | 2020-08-31 14:30:00 | Sync Meter
00209703| | 310 | 2020-08-31 14:30:00 | 2020-08-31 15:00:00 | WAPDA
00209706|37010114713| 250 | 2020-08-31 14:30:00 | 2020-08-31 15:00:00 | Sync Meter
00209707|37010114710| 150 | 2020-08-31 14:30:00 | 2020-08-31 15:00:00 | Sync Meter
....
执行上述操作的原因是，我想检查当特定来源为turned on时，哪个同步仪表正在提供数据。
目前，我已经在fiddle
中设置了一个查询 注意：由于一次将一个turned on作为一个来源，因此一个特定来源将有多个日期时间。例如，如果某个源在turned on至12:00:00 PM之间为13:00:00，则它将在其他时间再次为turned on，例如在18:00:00至20:00:00之间反之亦然。每个数据的持续时间为 10分钟，即每10分钟从电表中提取数据。

SELECT d.`msn`,d.`cust_id`,MAX(d.`kwh_t`),MIN(d.`data_date_time`),MAX(d.`data_date_time`),d.`s_type`
FROM `mdc_meters_data` d
WHERE d.`data_date_time`>='2020-08-31 00:00:00' AND d.`data_date_time`<='2020-08-31 23:59:59'
GROUP BY d.`s_type`
以下是结果
