Question : Where or between on row_number

I need to show some_content_field/s on a table , the range of the record i need to show is,
(N) record revers (when order by date) from the last record that mach the given date.

for this example
given date='2009-12-13 04:00'
N=4

"THE ROW_NUMBER FIELD DO NOT EXIST ON THE TABLE"

ID DATE&TIME row_number some_content_field
50 2009-12-13 01:00 1 XXXXXXXXXXXXXXXX
51 2009-12-13 01:00 2 XXXXXXXXXXXXXXXX
52 2009-12-13 01:00 3 XXXXXXXXXXXXXXXX
53 2009-12-13 04:00 4 XXXXXXXXXXXXXXXX
54 2009-12-13 04:00 5 XXXXXXXXXXXXXXXX
55 2009-12-13 04:00 6 XXXXXXXXXXXXXXXX

the result should be the row between 6-3 "WITHOUT THE ROW_NUMBR FIELD"

52 2009-12-13 01:00 3 XXXXXXXXXXXXXXXX
53 2009-12-13 04:00 4 XXXXXXXXXXXXXXXX
54 2009-12-13 04:00 5 XXXXXXXXXXXXXXXX
55 2009-12-13 04:00 6 XXXXXXXXXXXXXXXX

I try to do between on row_number function it didn't work

Answer : Where or between on row_number

The last note:

If the DATE&TIME is the real column name then it has to be enclosed into square brackets in all SQL statements:

                       
             DECLARE @n int, @givenDate smalldatetime  
SET @n = 4   
SET @givenDate = '2009-12-13 04:00'  
   
SELECT ID, [date&time], some_content_field    
  FROM ( SELECT TOP (@n) * FROM YourTable WHERE [date&time] <= @givenDate  
 ORDER BY [date&time] desc, ID desc) lastN   
 ORDER BY [date&time], ID
