Jon (or anyone else),
Is this an optimally formed query, considering it is a join of the 3 reference tables?
select s.abbrev, z.name, c.name
from us_zipcodes z, us_states s, us_counties c
where z.fips_state_code = s.fips_state_code and
z.fips_county_code = c.fips_county_code and
z.fips_state_code = c.fips_state_code and
z.zipcode=:zip_code;
It is to replace this query for the non-existant table:
select state_code, city_name, county_name
from zip_codes
where zip_code=:zip_code;
