Hi Cristian,

if it is the case all over your program, use a "setup" table containing
each users criteria and join against it!

somthing like
create table user_settings(
userid numeric(8,0),
year numeric(4),
month numeric(2)
);

then join like this:

select x,y,z
from yourtable,
user_settings
where yourtable.year = user_settings.year
and yourtable.month = user_settings.month
and user_settings.userid = :userid

this way you only need to supply one param.
