Select for partitioned table, will this work with sign?

Question

Hi,
I have partitioned table and select for it like :
PARTITION BY RANGE  ( "INDATE"  )
  (   PARTITION "PRT_20091201" VALUES LESS THAN (TO_DATE(' 2009-12-02 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN')...
   SELECT COLUMN_LIST FROM TABLE1   WHERE
           ( indate >= to_date(t_indate || t_timefrom, 'mm/dd/yyyy HH24:MI:SS'))                       AND
           ( indate <= to_date(t_indate || t_timeto,   'mm/dd/yyyy HH24:MI:SS'))                        AND... so selecting all info for the given date withing specifiied time period, and I'm using >= condition on partitioned column, do you think it will work correctly getting directly to the single partition, or Oralce requires me put strictly = sign for that column, and then additioanly I can probably select time period, something like:
SELECT COLUMN_LIST FROM TABLE1   WHERE
          ( indate = to_date(t_indate , 'mm/dd/yyyy'))                        AND
               ( trim_to_time(indate) >= to_char(t_timefrom, ' HH24:MI:SS'))              AND
               ( trim_to_time(indate) <= to_char( t_timeto,   ' HH24:MI:SS'))              AND... Tx all

TrI agree with David that the first example looked okay, but you should test to make sure. You can check individual partition contents by executing a query using the PARTITION option to specifiy a specific partition to check the values there.
