Thanks, it worked!
By the way, what does this "*j" mean there..? (this does not mean multiply there?)
And what if, I would like to declare v_to_date also, so that v_to_date is always + 1 month compared to v_date_from..?
-- This one will work, but can this be done simpler..?
v_to_date := (date_trunc('month',current_date)::date + interval '1 month' + interval '1 month'*j)::date;
Raul
