$[CHE_TEST@asterix1_impl] exec :phoneno := '9988585633';
PL/SQL procedure successfully completed.
$[CHE_TEST@asterix1_impl] ed
Wrote file c:\temp\afiedt.sql
  1  with data as (
  2    select substr(:phoneno, level, 1) no
  3    from dual connect by level <= length(:phoneno)
  4  )
  5  select count(*), no
  6  from data
