The only trick with this is that you need to join the car_parts table
twice (once for parent and once for child), and to do that you need to
give it different alias names:
select bom.parent_id,
ppart.name as parent_name,
bom.child_id,
cpart.name as child_name
from bill_of_materials bom
join car_parts ppart on (ppart.id=bom.parent_id)
join car_parts cpart on (cpart.id=bom.child_id);
