insert into link_table (licence_id, software_id)
select l.id, s.id
from softwares s,
licences l,
sierras o
where l.licence_ref = o.licence_ref
and l.renewal_data = o.renewal_data
and s.regno = o.regno
and s.platform = o.platform (in case you would have the same regno on
several platforms :)).
I don't see why you need any 'id' column in the link table.
