column "Distinct non-numeric chars" format a30
with t as (
           select '!' a from dual union all
           select '@' from dual union all
           select '#' from dual union all
           select '$' from dual union all
           select '%' from dual union all
           select '^' from dual union all
           select '&' from dual union all
           select '*' from dual union all
           select '(78^*)5$#7' from dual union all
           select ')!@#$0-99' from dual union all
           select '_454*(&--0' from dual union all
           select '+@#$%564' from dual union all
           select '=123' from dual union all
           select '135790' from dual
select  distinct substr(a,column_value,1) "Distinct non-numeric chars"
  from  (
         select  regexp_replace(a,'[[:digit:]]') a
           from  t
           where not regexp_like(a, '^[[:digit:]]+$')
        table(
              cast(
                   multiset(
                            select  level
                              from  dual
                              connect by level <= length(a)
                   as sys.odcinumberlist
