Question

Answer 1

Let's write the same sample as a CTE only:

with fg_rulez as (
  select 1 id,'<' symbol, 'less than' text from dual
  union all select 2, '>', 'greater than' from dual
   union all select 3, '$', 'dollars' from dual
  union all select 4, '+', 'and' from dual
),  fg_Data AS (
   SELECT 'amount $ must be < 1 + > 2' str FROM dual
   union all
   SELECT 'John is > Peter + has many $' str FROM dual
   union all
   SELECT 'Eliana is < mary + do not has many $' str FROM dual
), q(str, id) as (
  SELECT str, 0 id 
  FROM fg_Data 
     UNION ALL
  SELECT replace(q.str,symbol,text), fg_rulez.id
  FROM q 
  JOIN fg_rulez 
    ON q.id = fg_rulez.id - 1
)
SELECT str from q where id = (select max(id) from fg_rulez);
