I would like to extract each of the words in a string/value and print them as given below :-

WITH get_str
     AS (SELECT 'Porter Care Adventist Health Systems DBA Littleton Adventist Hospital'
                   txt
           FROM DUAL
         UNION
         SELECT 'Sample string for the query' txt FROM DUAL
         UNION
         SELECT 'Smith Carter Architects - Engineers, Inc. (US)' txt
           FROM DUAL
         UNION
         SELECT 'Avenue of the Americas Development Company LLC.' txt
           FROM DUAL)
SELECT *
  FROM get_str
