根据定义的时间间隔将开始和结束时间戳分为两个

Question

我有一个员工进出的时间。我想根据动态间隔条件进行分割

如果间隔为15:00

输入

EMP_ID  SWIPE_IN    SWIPE_OUT
4   2019-01-21 13:10:00.000 2019-01-21 15:45:00.000

所需的输出

EMP_ID  SWIPE_IN    SWIPE_OUT
4   2019-01-21 13:10:00.000 2019-01-21 15:00:00.000
4   2019-01-21 15:00:00.000 2019-01-21 15:45:00.000

Answer 1

您可以使用类似的东西

Declare @Interval Varchar(30) = '15:00'
Insert Into [TableName]
Select EMP_ID, CAST(Convert(Varchar, SWIPE_OUT, 23)+ ' ' + @Interval As DateTime), SWIPE_OUT
From [TableName]
Where SWIPE_OUT > CAST(Convert(Varchar, SWIPE_OUT, 23)+ ' ' + @Interval As DateTime) 

Update [TableName]
SET SWIPE_OUT = CAST(Convert(Varchar, SWIPE_OUT, 23)+ ' ' + @Interval As DateTime)
Where SWIPE_IN <> CAST(Convert(Varchar, SWIPE_OUT, 23)+ ' ' + @Interval As DateTime) 
AND SWIPE_OUT > CAST(Convert(Varchar, SWIPE_OUT, 23)+ ' ' + @Interval As DateTime)
