Hy Maik,
you can select it directly from the tables using following sql statement
(but it's same as using views):
select
t1.id, t1.f1, t2.f2
from
(select id, sum(amount) f1
from table1
group by id) t1,
(select id, sum(amount) f2
from table2
group by id) t2
where
t1.id = t2.id
but, you must also know that in this way you may not get all the records
(sum of amount of all id-s) if this is your intention, but just sum of
amount of identical id-s (contained in both tables).
Maybe this will help you.

TIP 2: you can get off all lists at once with the unregister command
