SQL> with test (col) as
  2    (select 'MERGE|WorkRelationship|||2020/12/31|RESIGNATION|Y||XYZ Limited|12345A' from dual
  3     union all
  4     select 'Little|Foot' from dual
  5    )
  6  select rtrim(regexp_substr(col, '[^|]*\|?', 1, column_value), '|') val
  7  from test cross join
  8    table(cast(multiset(select level from dual
  9                        connect by level <= regexp_count(col, '\|') + 1
 10                       ) as sys.odcinumberlist))
 11  order by col, column_value;
