我有任务列表，
对于每个人，我都有一个TaskID，startTime和StopTime（以毫秒为单位，从1-1-1970开始）和一个用户列表（#Tasks）。
我需要计算每个用户花在任务上的时间，该时间按白天/晚上，星期或周末，固定时间/加班时间划分，并考虑夜间时间从10:00 PM到06:00 AM。
当然有更好的解决方案，但到目前为止，我知道了：
IF OBJECT_ID('tempdb..#Tasks') IS NULL
BEGIN
create table #Tasks
(
TaskID nvarchar(50),
DateStart bigint,
DateStop bigint,
Staff nvarchar(100)
)
insert into #Tasks values
('C001',1554181200000,1554190200000,'john,jack'),
('C002',1554202800000,1554212700000,'tom,john'),
('C003',1554228000000,1554246900000,'john,franck'),

END

我现在需要：
1）按天分组结果，将WeekDay，WeekNight，WeekendDay，WeekendNight和TotalMinutes相加，并合并时间范围，例如在4月2日“ 05：00-07：30 | 11：00-13：45 | 18：00 -23：00“
2）由于是午餐时间，所以不能汇总12:00和12:30（如果有）之间的时间
3）考虑到每天8小时后必须将其计算为加班时间，因此我必须将总分钟数分为时间和加班时间，但要取决于加班时间是白天还是晚上还是周末
4）最终使用假期表
换句话说，我们应该拥有这个：
Day TotalMinutes WeekDay WeekNight WeekendDay WeekendNight WeekDayOverTime WeekNightOvertime WeekendDayOvertime WeekendNightOvertime UserName timeframe
02/04/2019 630 420 60 0 0 45 75 0 0 john 05:00-07:30|11:00-13:45|18:00-23:00
07/04/2019 225 0 0 165 60 0 0 0 0 john 05:00-08:45
因为（在4月2日）我们有：
第一项任务：
常规夜间时间60分钟
常规时间90分钟
第二项任务：
正常白天时间为165分钟，但由于午餐时间而只需计算135分钟
第三项任务：
240天时间
75夜间
但是由于任务1和任务2总计285分钟，因此第三项任务的前185分钟仅是常规日间时间：其余的45是加班日间，而随后的75夜间实际上是OvertimeNightTime
答案 0 :(得分：1)
通过这种方法，第一个CTE（properDates）获得开始和停止日期时间，因此您无需在查询中重复该公式。
第二个CTE（splittedMinutes）将获得与您当前方法相同的数据，但第一个CROSS APPLY除外，它将交叉的时间范围与午餐时间分开。第二个CROSS APPLY获取分钟数和isWeekend值。
在第三个CTE（qualifiedMinutes）中，我使用窗口分区来获取累积的分钟数并在适用时生成加班时间。
最后，我使用选择性的SUM将汇总中的工作日和周末分开
