【中文标题】计算通过的服务时间【英文标题】：Calculating passed service hours 【发布时间】：2021-01-15 12:32:22 【问题描述】：

我正在尝试根据服务时间计算自记录服务请求以来经过的时间（服务时间）。

开始时间是记录工单的时间 (date_logged)，结束时间可以是当前时间（对于打开的工单）或 date_closed 对于已关闭的工单。

服务时间因工单被分配到的部门而异，如下例所示（我表中的所有时间和日期都具有数据类型 datetime ):

Ticket-Nr.	Department	date_logged	date_closed	start_mon	end_mon	start_tue	end_tue	start_wed	end_wed	start_trs	end_trs	start_fri	end_fri	start_sat	end_sat
1234567	A	06.01.21 11:30:52		01.01.2001 07:30	01.01.2001 16:45	01.01.2001 07:30	01.01.2001 16:45	01.01.2001 07:30	01.01.2001 16:45	01.01.2001 07:30	01.01.2001 16:45	01.01.2001 07:30	01.01.2001 13:00
8912345	B	13.01.21 09:14:16		01.01.2001 07:00	01.01.2001 16:30	01.01.2001 07:00	01.01.2001 16:30	01.01.2001 07:00	01.01.2001 16:30	01.01.2001 07:00	01.01.2001 16:30	01.01.2001 07:00	01.01.2001 16:30	01.01.2001 07:00	01.01.2001 15:00
6789012	C	14.01.21 10:48:01	14.01.21 11:40	01.01.2001 07:00	01.01.2001 16:30	01.01.2001 07:00	01.01.2001 16:30	01.01.2001 07:00	01.01.2001 16:30	01.01.2001 07:00	01.01.2001 16:30	01.01.2001 07:00	01.01.2001 16:30	01.01.2001 07:00	01.01.2001 15:00
3456789	D	15.01.2021 09:41:00		01.01.2001 08:00	01.01.2001 15:00	01.01.2001 08:00	01.01.2001 15:00	01.01.2001 08:00	01.01.2001 15:00	01.01.2001 08:00	01.01.2001 15:00	01.01.2001 08:00	01.01.2001 13:00
0123456	B	02.01.2021 13:12:00	...	...	...	...	...

结果应该看起来像这样（减去“当前日期时间”列，这只是为了上下文）：

Ticket-Nr.	department	date_logged	service time [hh:mm]	current datetime	date_closed
1234567	A	06.01.21 11:30:52	62:33	14.01.2021 12:03
8912345	B	13.01.21 09:14:16	12:19	14.01.2021 12:03
6789012	C	14.01.21 10:48:01	00:28	14.01.2021 12:03	14.01.21 11:40
...	...	...	...	...	...

A、B、D部门必须包括公共假期。

【问题讨论】：

鉴于您的业务规则的复杂性，我建议您创建每天一行和部门的表格，指定当天的工作时间。 @GordonLinoff 好点！我希望现在更清楚了。如果你没有太多的部门那么你仍然可以使用我的方法：***.com/questions/41936398/… 请edit 使用minimal reproducible example 提出您的问题，包括DDL (CREATE TABLE) 语句或您的表和DML (INSERT) 语句用于您的示例数据。虽然表格可能看起来不错，但对于回答问题的人来说，必须将表格中的所有数据提取到 INSERT 语句中并猜测您的数据类型是没有帮助的。另外，假设一个部门对所有工单的服务时间始终相同，看起来您的更新违反了第 3 范式，并且您将在每一行。最好回到你以前的结构并有一个单独的小时表。 【参考方案1】：

您可以直接计算小时数（扩展您的previous question）：

【讨论】：

非常感谢您的回答！不幸的是，我意识到我对表格结构的解释不够充分......服务时间实际上与门票在同一个表格中。我已经编辑了我原来的问题，所以你知道它是什么样子的。我尝试通过将 s.hours_day 与 24*(day_end - day_start) 交换来更改您的脚本，但我收到一个错误，告诉我“不允许日期 + 日期”（day_start 和 day_end 列具有日期时间格式）。再次感谢您，给您带来的不便深表歉意。 @Acinogara 变化不大db<>fiddle。
