Why do you need the to_char?

But wouldn't it work anyway with

to_char(a.updated_date,'dd/mm/yyyy hh24:mi:ss') =

( select to_char(max(updated_date),'dd/mm/yyyy hh24:mi:ss'))

which will also use the 24 hour clock instead of

to_char(a.updated_date,'dd/mm/yyyy hh:mi:ss') =

( select max(to_char(updated_date,'dd/mm/yyyy hh:mi:ss'))

Hi All,

I am using the to_char function in the following query. But it treats the date '31/12/2001' as greater than '01/01/2002'. Is there any solution to fix this problem?

select distinct(a.default_type_id), a.new_val from amend_default_value a, amend_default_value b

 where a.effective_from <= sysdate and
       a.effective_to    >= sysdate and
       a.group_id = '942'       and
       a.default_type_id = b.default_type_id     and
       to_char(a.updated_date,'dd/mm/yyyy hh:mi:ss') = 
       ( select max(to_char(updated_date,'dd/mm/yyyy hh:mi:ss')) 
       from amend_default_value c
       where c.effective_from <= sysdate and
       c.effective_to    >= sysdate and
       c.group_id = '942' and
       c.default_type_id = b.default_type_id);

Thanks in advance.

regards,
Karthik
