SELECT * from ProdCar A WHERE A.EndDate > GETDATE ()
and A.EndDate > = ' 2019-11-07 00: 00: 00.000 '
the aND ' 2019-11-07 18 is: 00: 00.000 ' > A.BeginDate
- implement 2
- given time interval (begin, end), the database fields BeginDate EndDate, now determines whether there is an intersection between them
