一项活动中有多个延迟。可以将延迟放置在边界处，并且许多延迟可以存在于一个 Long 活动中。我们需要优先考虑延迟记录，因此我们应该忽略延迟记录中出现的任何活动记录

我在一个表中有两组记录，即特定机器在特定 shiftdate 和 shift 中的 ACTIVITY 和 DELAY。在某些轮班日期和轮班期间，活动和延迟之间发生重叠。活动记录之间发生的延迟记录应优先考虑，活动记录应围绕延迟记录相应拆分，从而消除活动和延迟之间的重叠

我应该使用什么方法来根据延迟分解活动记录，并将延迟优先于活动记录。

创建表的代码如下

CREATE TABLE [dbo].[Activity_Delays](
    [Type] [nvarchar](15) NOT NULL,
    [Shiftdate] [datetime] NOT NULL,
    [Shift#] [int] NOT NULL,
    [MachineID] [nvarchar](10) NOT NULL,
    [StartTime] [datetime] NOT NULL,
    [EndTime] [datetime] NOT NULL
) ON [PRIMARY]

这是您的示例输出的查询：

select *, Activity_Delays.StartTime SortStartTime
from Activity_Delays
where 
   Type = 'Delay'
union all
select distinct Activities.*, Delays.StartTime SortStartTime
from
 Activity_Delays Delays
 inner join Activity_Delays Activities on Activities.ShiftDate = Delays.ShiftDate and
                                      Activities.MachineID = Delays.MachineID and
                                      ((Delays.EndTime between Activities.StartTime and Activities.EndTime) or
                                      (Delays.StartTime between Activities.StartTime and Activities.EndTime))
where
  Activities.Type = 'Activity' and
  Delays.Type = 'Delay'
order by MachineID, ShiftDate, SortStartTime, 1 desc

这里也是一个工作输出
