Mario,
If your function returns a record, you have to treat it like it's a
relation (table). So you don't select it, you select from it.
Try:
select * from get_unidades(10, 1, 15, 17);
Also you may have to give it an explicit variable list such as:
select * from get_unidades(10,1,15,17) as (codigo numeric(3,0),
descripcion text);
Best,
Randall
