Date query problem

Question

Hi,
On a report I'm trying to do a date query:
select * from table v
where ..........
and ( to_date(v.fecha_inicio, 'dd/mm/yyyy')
between nvl(to_date(:P_BEGIN, 'dd/mm/yyyy'),
to_date('01/01/0001', 'dd/mm/yyyy'))
and nvl(to_date(:P_END, 'dd/mm/yyyy'),
to_date('31/12/9999', 'dd/mm/yyyy')) )
and could not get the right data (return no rows), I though it was a problem with my itmes so changed the item reference for the actual values:
select * from table v
where ..........
and ( to_date(v.begin_date, 'dd/mm/yyyy')
between nvl(to_date('01/10/2006', 'dd/mm/yyyy'),
to_date('01/01/0001', 'dd/mm/yyyy'))
and nvl(to_date('31/10/2006', 'dd/mm/yyyy'),
to_date('31/12/9999', 'dd/mm/yyyy')) )
and the result is the same.
If change to
and (to_char(v.fecha_inicio, 'dd/mm/yyyy')
between nvl(to_date('01/10/2006', 'dd/mm/yyyy'), to_date('01/01/0001', 'dd/mm/yyyy') )
and nvl(to_date('31/10/2006', 'dd/mm/yyyy'), to_date('31/12/9999', 'dd/mm/yyyy') ) )
Sends a not a valid month error but if run the same query on sqldeveloper it works right.
My question is why I could not get the right data on apex ?
Thanks you

Answer 1

I made the changes and is the same thing, no rows returned. If I try to evaluate between or > < is the same.
I tried
AND (to_char(v.fecha_inicio, 'yyyy') = '2006' )
AND (to_char(v.fecha_inicio, 'mm') = '11' )
And is the only thing I found that works !!!
So I'm thinking to change my conditions so select a month and year to show. Don't think my user will be happy but for the moment ......
Thanks
