Hi all, is it possible to update a table when the current_date in
rdb$database changes to the next day?

I need to reset a delivery counter to 0 in all the orders on a system.
I can presently do this two ways.

When I print a delivery label I do it via a SP...
cut-down start of SP
select current_date
from rdb$database
into :human_date;
select p.label_counter_date
from paramfil p
into :counter_date;
if (:human_date>:counter_date) then -- it must be the next day
begin
update paramfil p
set p.label_counter_date=current_date;
update orditems oi
set oi.label_day_count=0;
end
then continue with SP to print labels as normal
This does cause a delay to the first set of delivery labels printed each
day.

I could write and run a small Delphi program which would only have the
above code as an active item. I could then use Windows (its a Windows
2016 server) to run this program at midnight plus a minute, as a
scheduled task.

But that seems a lot for something I think I should do within the
database itself. I've tried to create a trigger on rdb$database but
cannot, I don't have it available and I understand that I should not
'mess' with it anyway.

Any help or suggestions gratefully received.
