Question

I have created a trigger to set the time value of a Column of data type time() to NULL when ever it is greater than GETDATE().

I am getting an error which indicates a conflict between the columns’ data type time() and GETDATE() since GETDATE() retrieves date and time.

My question is how can I get the time portion only of the GETDATE() to use it in my trigger?

Trigger Code:

  create trigger trig1 
  on [dbo].[Products]
  after insert
  as
  update Products
  set ParkingStartTime = null
  from Products
  join inserted i
  on i.ParkingStartTime  = Products.ParkingStartTime 
  where i.ParkingStartTime >= GETDATE();

Regards.

based on the comment, you cannot implicitly cast time to datetime – so you need to convert it manually:

create trigger trig1    
on [dbo].[Products]   
after insert   
as   
update Products   
set ParkingStartTime = null   
from Products   
join inserted i   
on i.ParkingStartTime  = Products.ParkingStartTime    
where i.ParkingStartTime >= CAST(GETDATE() AS time(7))
