Postgres 8.4 or higher

Starting with a particular GeoNames id (in this case 6429727) get its name and the name and id of each place containing it all the way up the hierarchy:

Code:
 WITH RECURSIVE geonametree AS
 
 (SELECT geoname.geonameid AS id, geoname.name AS name, hierarchy.parentid AS parent, hierarchy.childid AS child
 FROM hierarchy
 	JOIN geoname ON geoname.geonameid = hierarchy.childid 
 	WHERE geoname.geonameid = 6429727
 
 UNION ALL
 
 SELECT geoname.geonameid AS id, geoname.name AS name, hi.parentid AS parent, hi.childid AS child
 FROM hierarchy AS hi
 	JOIN geoname ON geoname.geonameid = hi.parentid 
 	INNER JOIN geonametree AS gt ON (hi.childid = gt.parent)
 )
 SELECT id, name, parent, child
 FROM geonametree;
