         ON AFFILIATEMEMBER.CATEGORYSUBGROUP_ID =

Problem

AFFILIATEMEMBER.CITYOTHER AS OTHERCITY,
         CITY.DESCRIPTION AS CITY,
         CITY.CITY_ID,
If CITYOTHER IS PRESENT, THEN IT SHOULD NOT DISPLAY  CITY.DESCRIPTION AS CITY,
         CITY.CITY_ID,

IF CITY_ID IS PRESENT THEN IT SHOULD NOT DISPLAY
 CITY.DESCRIPTION AS CITY,
         CITY.CITY_ID,

Answer : Help In Query

Then http:#a33324276 should be right. If you do need the CITY_ID, then

SELECT   AFFILIATEMEMBER.AFFILIATEMEMBERNO,
         AFFILIATEMEMBER.AFFILIATEMEMBERCLUBNO,
         COALESCE(AFFILIATEMEMBER.CITYOTHER, CITY.DESCRIPTION) AS CITY,
         COALESCE(AFFILIATEMEMBER.CITY_ID, CITY.CITY_ID) AS CITY_ID,
         STATE.DESCRIPTION AS STATE,
         STATE.STATE_ID,
         COUNTRY.DESCRIPTION AS COUNTRY,
         COUNTRY.COUNTRY_ID,
