just try to give you some ideas. Maybe wrong. first get the org_city and org_state then use another select to get des_city and state Table A (org_zip, dest_zip), Table zip(zipcode, city, state) select zip.city as org_city ,zip.state as org_state, A.dest_zip into table C from A,zip where A.org_zip=zip.zipcode; select C.city,C.state,zip.city as des_city, zip.state as des_state from C ,zip where c.dest_zip=zip.zipcode;
