I have trigger after Insert that update field in the table with GETUTCDATE() but after Insertion I see the value = null
SET NOCOUNT ON
UPDATE [dbo].[Employee]
SET [CurrentDate] = GETUTCDATE()
FROM inserted
WHERE inserted.[Id] = [dbo].[Employee].[Id]

It appears that none of that code is the actual problem. Please post all of the code for the trigger.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

I take that back... that's actually an illegal form of update that will sometimes work and sometimes not. I'll explain more after I see the rest of the code for the trigger.

I look forward to hearing that explanation.

In the meantime, wouldn't something like this work?

SET NOCOUNT ON

UPDATE a

SET [CurrentDate] = GETUTCDATE()

FROM [dbo].[Employee] a

JOIN inserted b

ON a.[Id] = b.[Id]

My mantra: No loops! No CURSORs! No RBAR! Hoo-uh![/I]
My thought question: Have you ever been told that your query runs too fast?

My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.

I was about to make that same comment but noticed you had. 😉 I know what the problem is but I am having a hard time finding the explanation of why it happens.

You don't understand. I need to see ALL the trigger code because there are other nuances in a trigger that could be important.
