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.
