John,

If you do not want to specify column names then you need a 'double action' query, eg something such as

  set pause off
  set echo off
  set verify off
  set pagesize 0
  set feedback off
  set recsep off
  spool tally_ho.sql
  select decode(rownum, 1, 'update &&my_table set ',

                             ', ') || column_name
                                   || ' = replace(' || column_name 
                                   || ', <suitable stuff>);'

  from user_tab_columns
  where table_name = upper('&&my_table')     and column_type in ('CHAR', 'VARCHAR2');   spool off
  set echo on
  set feedback on
  @tally_ho

That's basically the idea.
