Could you please put all pertinent information of your question in the
body, and not only in the subject. It makes questions a lot easier to
read (especially on mobile devices).

I'm sorry, I rewrite the question:

  what is more performant: "EXTRACT (YEAR FROM DT.DATA) <= 2016" or "DT.DATA <= '12/31/2016'"?

I would prepare myself for a table that grows rapidly.

Is the same in FB 2.5.6 or 3.0.1?

Thanks
