a strange problem

hi all,

i have a very strange problem. i have query like this

select
a.id as queue_id, b.*, c.text
from xxx a left join yyy b on (a.SMS_ID = b.id)
left join zzz c on (c.content_id = b.content_id)
where
is_send = 'N' and
day in (-1, to_number(to_char(SYSDATE, 'D'))) and
(minute = -1 or
minute  <= to_number(to_char(sysdate, 'HH24')) * 60 + to_number(to_char(sysdate, 'MI')))
and
c.text is not null and
(b.last_sent_sms is null or b.last_sent_sms != c.text) and
(c.content_date is null or (to_char(sysdate, 'yyyy/mm/dd') = to_char(c.content_date, 'yyyy/mm/dd')))
and (
b.comparison_operator is null or
(b.comparison_operator = '=' and b.comparison_value = c.price) or
(b.comparison_operator = '>' and b.comparison_value > c.price) or
(b.comparison_operator = '<' and b.comparison_value < c.price)
)

when i run this from toad it works fine and return 2 row but when i want to run in my java project it work very strangely and return only 1 work.

i couldnt understand anything why it behaves like that. it problem cause of java.

if you help me, i will be pleased.
thanks in advance.
