If you are using oracle 10g or higher, you can use the regexp_replace function http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions130.htm

select regexp_replace(your_column, '62([:digit:]*)', '0\2')
from your_table;

Or a more old-fashioned way without:

select case
         when your_column like '62%' then '0' || substr(your_column, 3)
       else
         your_column
       end
from your_table;

Just be careful with leading spaces or other characters in your phone number strings.
