Query to select records between 2 different times

Question

Hi all,
With trap_store table as (trap_id number,trap_received date))
and trap_time table as (from_time varchar2(10),to_time varchar(10))
How to i select records from trap_store table where time part of trap_received is between from_time and to_time of trap_time table.
Need to retrive records from trap_store table between 2 times. data in from_time and to_time(varchar columns) are stored in format HH24:MI:SS
from_time and to_time range can span over 2 days ie; from_time can be 23:00:00 and to_time can be 01:00:00
Thanks in advance,

Hi,
Here's one way:
WITH     got_received_time     AS
     SELECT  trap_id, trap_received
     ,     TO_CHAR (trap_received, 'HH24:MI:SS')     AS received_time
     FROM     trap_store
SELECT     trap_id, trap_received
FROM     trap_store     s
WHERE     EXISTS (
                SELECT  1
             FROM        trap_time
             WHERE   (    from_time  <= to_time
                     AND     s.received_time  BETWEEN  from_time
                                  AND       to_time
             OR        (    from_time  >  to_time
                     AND  (   s.received_time <= from_time
                              OR  s.received_time >= to_time
;If you'd care to post CREATE TABLE and INSERT statements for a little sample data, and the results you want from that data, then I could test this.
