In Torque, you can use the Criteria.addJoin() method to link two tables. Using that feature, you cannot use the Peer.doSelect() method, but have to use Peer.doSelectVillageRecords(), which will return all columns of all joined tables in a village Record object, with no big difference to plain JDBC in handling. If you need or want Torque data objects, you have to extract them one by one from the result set. For a project of us, we wrote a helper class named JoinHelper that does this business for you AND returns an tree of Torque objects. In your case, it would return COMPANY objects that can be queried for their BUILDINGs, which again know their EMPLOYEEs. Please search the thread about two years ago in Torque archive and the discussion about. JoinHelper massively uses reflection, but is tested quite well and in production. If you have more detailled questions... you're welcome.
