as you said before, you can import this into sql express with no problems correct?
you can do something like this
SELECT SYSTEM_CODE, DATE_FIELD
WHERE DATE_FIELD >= convert(datetime, '2008-12-1 12:00', 120)
AND DATE_FIELD < convert(datetime, '2008-12-2 12:00', 120)
you can run this sql select, now its a matter of what you are familiar with to get it to a text file, you can do it with dts / ssis, c#, whatever else you may prefer
