This query selects the most recent advertisement (in table  
wha_listing) for all properties (in table wha_property) and returns  
the sales agency (in table wha_agency), as well as other data.  The  
query works as expected.

SELECT DISTINCT ON (property_id)
property_id, date, wha_property.propnum, wha_street.street_name,  
wha_suburb.suburb_name, wha_agent.first_name, wha_agent.last_name,
FROM wha_listing, wha_agent, wha_agency, wha_property, wha_street,  
WHERE = wha_street.suburb_id
AND = wha_property.street_id
AND = property_id
AND = wha_agent.agency_id
AND = agent_id
AND >= "2009-01-01" ORDER BY wha_listing.property_id, DESC;

I need the resulting list to be sorted by

Can I do this by adding something to this query?
