  2  (
  3  SELECT 1, 'M,P,Y,N,C,P' FROM dual UNION ALL
  4  SELECT 4, 'N,E,A' FROM dual UNION ALL
  5  SELECT 10, 'N,C,R,P' FROM dual)
  6  SELECT id, regexp_substr(rights, '[^,]+',1,level) res
  7  FROM a
  8  CONNECT BY  level - 1 <= regexp_count(rights,',')  /*  regexp_count:- 11g */
  9  AND prior id = id
10  AND prior sys_guid() IS NOT NULL /* sys_guid:- 11g */
11  ORDER BY id
12  /
        ID RES
