I cannot use Distinct or Unique clause due to Organisation restrictions. Is there a way to modify the code so that no duplicate values are shown? My code is listed below:

`SELECT PER_PERSON_NAMES_F.TITLE,
               PER_PERSON_NAMES_F.FIRST_NAME,
               PER_PERSON_NAMES_F.LAST_NAME,
               PER_PERSON_NAMES_F.FULL_NAME,
               PER_PERSON_NAMES_F.DISPLAY_NAME,
FROM PER_PERSON_NAMES_F,PER_ALL_PEOPLE_F, PER_PERSONS
WHERE PER_PERSON_NAMES_F.PERSON_ID=PER_ALL_PEOPLE_F.PERSON_ID
AND PER_PERSON_NAMES_F.PERSON_ID=PER_PERSONS.PERSON_ID
AND PER_ALL_PEOPLE_F.PERSON_ID=PER_PERSONS.PERSON_ID
AND name_type='GLOBAL'
ORDER BY PER_PERSON_NAMES_F.FULL_NAME.`
