Question

我有ShiftMaster表，每台机器分配开始时间和结束时间，机器可以多班。有一些工作是在机器上进行。

即ShiftMaster，例如

MachineID   SHIFTID     STIME           ETIME
A110T02     1       07:00:00.0000000    16:00:00.0000000
A110T02     2       14:00:00.0000000    23:00:00.0000000
A110T02     3       23:00:00.0000000    07:00:00.0000000

如果我通过机器名称，开始作业日期时间和结束作业时间，它应该重新调整班次开始时间和结束时间。

我面临第三班的问题，因为它涉及半夜时间，即两天

我期待提供这样的输入

@machineName = 'A110T02'

@startJobdatetime = '2015-12-01 23:02:00'

@EndJobdatetime = '2015-12-01 23:20:00'

结果应该返回

3 23：00：00.0000000 07：00：00.0000000

中给出了正确的格式

Answer 1

这应该有效：

declare @machineName varchar(50) = 'A110T02'
declare @startJobdatetime datetime = '2015-12-01 23:02:00'
declare @EndJobdatetime datetime = '2015-12-01 23:20:00'

SELECT *
FROM @ShiftMaster
WHERE MachineID = @machineName
    AND CAST(DATEADD(hour, -7, @startJobdatetime) as time) >= DATEADD(hour, -7, STIME)
    AND CAST(DATEADD(hour, -7, @EndJobdatetime) as time) <= DATEADD(NANOSECOND, -100, DATEADD(hour, -7, ETIME))

您必须对其进行测试并确保23：59：59.999周围没有舍入错误。
如果从上午7点开始转换，基本上将所有内容都移动了7小时。

<强>输出：

MachineID   SHIFTID STIME               ETIME
A110T02     3       23:00:00.0000000    07:00:00.0000000

数据：

declare @ShiftMaster table(MachineID varchar(50), SHIFTID int , STIME time, ETIME time) INSERT INTO @ShiftMaster(MachineID, SHIFTID, STIME, ETIME) values ('A110T02', 1, '07:00:00.0000000', '16:00:00.0000000') , ('A110T02', 2, '14:00:00.0000000', '23:00:00.0000000') , ('A110T02', 3, '23:00:00.0000000', '07:00:00.0000000')

Answer 2

试

 DECLARE @Tmp table (MachineID VARCHAR(20),SHIFTID INT,STIME VARCHAR(25),ETIME VARCHAR(25)) 
INSERT @Tmp SELECT 'A110T02',1,'07:00:00.0000000','16:00:00.0000000'
INSERT @Tmp SELECT 'A110T02',2,'14:00:00.0000000','23:00:00.0000000'
INSERT @Tmp SELECT 'A110T02',3,'23:00:00.0000000','07:00:00.0000000'

DECLARE @machineName VARCHAR(20) = 'A110T02'
 ,@startJobdatetime VARCHAR(25) = '2015-12-01 23:02:00' 
 ,@EndJobdatetime VARCHAR(25) = '2015-12-01 23:20:00'
 ,@ShiftId INT = 3

    ;with t11 as 
 (select MachineID,SHIFTID,
 cast(CAST(left(@startJobdatetime,10) AS datetime)+cast(stime as time) as datetime) as st,
 cast(cast(left(@startJobdatetime,10) AS datetime)+cast(ETIME as time) as datetime) et 
 from @tmp where cast(etime as time)>cast(stime as time)
  union all
  select MachineID,SHIFTID,
  cast(CAST(left(@startJobdatetime,10) AS datetime)+cast(stime as time) as datetime),
  cast(CAST(left(@startJobdatetime,10) AS datetime)+cast('23:59:59.999' as time) as datetime) 
  from @Tmp where cast(etime as time)<cast(stime as time)
  union all
 select MachineID,SHIFTID,
 CAST(left(@startJobdatetime,10) AS datetime),
 cast(cast(left(@startJobdatetime,10) as datetime)+cast(ETIME as time) as datetime) from @Tmp 
 where cast(etime as time)<cast(stime as time)
 ) 
 select t.MachineID,t.SHIFTID,t.STIME,t.ETIME from t11  join @Tmp t on t.MachineID=t11.MachineID  and t.SHIFTID=t11.SHIFTID
 where t11.MachineID = @machineName  and st<=cast(@startJobdatetime as datetime) and et>=cast(@EndJobdatetime as datetime)
