it's strange! With 7.1.3 here I don't get any parser error, but
"ERROR: Attribute people_attributes.people_id must be GROUPed or used
in an aggregate function". So I changed Josh's statement to
SELECT people.people_id, people.name,
people.address,
people_attributes.attribute_name,
people_attributes.attribute_value
FROM people, people_attributes,
( SELECT people_id, count(*) as match_count
FROM people_attributes, search_attributes
WHERE search_id = 31
AND people_attributes.attribute_name =
search_attributes.attribute_name
AND people_attributes.attribute_value ~*
search_attributes.attribute_value
GROUP BY people_id) matches,
( SELECT count(*) as attribute_count
FROM search_attributes
WHERE search_id = 31 ) searched
WHERE people.people_id = people_attributes.people_id
AND people.people_id = matches.people_id
AND matches.match_count = searched.attribute_count;
and it seems to work now.
