know how to generate joins for self-referential relationships that
you could then reference externally in your criterion. while its

but the most likely cause for what youre seeing is that if any
element of the primary key in a result row is None, no

Another issue with the same setup:
node = query.select_by(name='konsole19.xx..com')[0]
print query.select_by(console=node)
The debugging output shows this:
INFO:sqlalchemy.engine.base.Engine.0x..74:SELECT node.cport AS node_cport,
node.type_id AS node_type_id, node.locshelf AS
