Answer 1

since you convert the date to character format you won't be able to use the > or <
you might want to use the trunc() function and convert the '05-01-2005' in date datatype:
  select distinct to_char(LAST_MODIFIED_DATE, 'DD/MM/YYYY') start_date
    from ccst_acctsys_account
   where trunc(LAST_MODIFIED_DATE) >= to_date('05-01-2005','dd-mon-yyyy');Message was edited by:

Jonh has the same solution. You might want to try including the TRUNC() function.
