Why would you want to do that - convert two dates into a char and then
compare them ? This is not a problem but it is how char comparisions work.
They are compared char by char to see which one is greater on the ASCII
chart.
See this : SQL > select '1' from dual where '3' > '10';

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
