Query Help.

I need to query data from "03/30/2014 2:00 A.M. through 04/01/2014 4:00 P.M.".  The real sp in production is not return correct data
and how can I get the result below.  I have over 6 millions rows in production table and is there an easy way to filter out only
certain date and time range without missing any rows.  SQL 2012.

Thank you in advance.

IF OBJECT_ID('Tempdb.dbo.#Temp', 'u') IS NOT NULL
  DROP TABLE #Temp
GO

CREATE TABLE #Temp
(
  objie       INT       NULL,
  eventdate   DATETIME  NULL,
)
GO

INSERT #Temp VALUES (30620,  '2014-03-29 06:00:00.000'),
                    (357087, '2014-03-31 02:01:54.000'),
                    (357081, '2014-03-31 01:59:48.000'),
                    (357740, '2014-03-31 04:02:01.000'),
                    (359448, '2014-04-01 16:00:01.000'),
                    (359456, '2014-04-01 19:23:48.000');
GO

eventdate   eventdate1          time
----------- ------------------- ------
30620       2014-03-29 06:00:00 6:00AM
357087      2014-03-31 02:01:54 2:01AM *
357081      2014-03-31 01:59:48 1:59AM
357740      2014-03-31 04:02:01 4:02AM *
359448      2014-04-01 16:00:01 4:00PM *
359456      2014-04-01 19:23:48 7:23PM

-- Result want:
eventdate   eventdate1          time
----------- ------------------- ------
357087      2014-03-31 02:01:54 2:01AM
357740      2014-03-31 04:02:01 4:02AM
359448      2014-04-01 16:00:01 4:00PM

--Testing... need a better way to pass in date and time range.

    SELECT objie
           eventdate,
           CONVERT(CHAR(19),eventdate, 120) AS 'eventdate1',
           RIGHT(CAST(eventdate AS DATETIME), 6) AS 'time'
      FROM #Temp
     WHERE CONVERT(CHAR(19),eventdate, 120) > '2014-03-31 02:00:00' AND CONVERT(CHAR(19),eventdate, 120) <= '2014-04-01 16:01:00'
    GO
