show records after current time - sql-server

Question

Actually I want some records from my database. There is a field Time_From. I just want to show only those records which are after DateTime.Now().
But it is not showing, it shows records before and after DateTime.Now()
Select *
from mytable
where Vehicle_Booking_Date= #Vehicle_Booking_Date
AND Time_From > #Time_From order by Time_From"
The table definition (from the comment)
CREATE TABLE [dbo].[mtblVehicle_Booking]
(
[Sno] [int] IDENTITY(1,1) NOT NULL,
[Vehicle_Number] [nvarchar](100) NULL,
[Vehicle_Booking_Date] [datetime] NULL,
[Time_From] [datetime] NULL,
[Time_To] [datetime] NULL,
[Vehicle_Used_By] [varchar](100) NULL,
[Vehicle_Booked_By] [varchar](100) NULL,
[Cost_Code] [nvarchar](50) NULL,
[Budget_Line] [nvarchar](50) NULL,
[Purpose] [varchar](20) NULL,
[Destination] [nvarchar](500) NULL,
[Trip_Details] [nvarchar](500) NULL
)
ON [PRIMARY]

Answer 1

If you want to select all records whose Time_From is greater than current time and date is equal to specified date,
Select *
from mytable
where Vehicle_Booking_Date= #Vehicle_Booking_Date
AND Time_From > now() order by Time_From'

Answer 2

You have not mentioned what database you are using. But concept remains same. Just substract the other date time from current time. If it is greater than 0 it means that the given date time is greater than the current date time.
Sample SQL
Select *
from mytable
where Vehicle_Booking_Date= #Vehicle_Booking_Date
AND DATEDIFF(Time_From,SYSDATETIME()) > 0
Hope this helps.
