i'm trying last datetime record table happens store multiple status. table looks so:

+---------+------------------------+-------+ |filename |dates                   |status | +---------+------------------------+-------+ |abc.txt  |2012-02-14 12:04:45.397 |open   | |abc.txt  |2012-02-14 12:14:20.997 |closed | |abc.txt  |2013-02-14 12:20:59.407 |open   | |dfg.txt  |2012-02-14 12:14:20.997 |closed | |dfg.txt  |2013-02-14 12:20:59.407 |open   | +---------+------------------------+-------+

the results should 

+---------+------------------------+-------+ |filename |dates                   |status | +---------+------------------------+-------+ |abc.txt  |2013-02-14 12:20:59.407 |open   | |dfg.txt  |2013-02-14 12:20:59.407 |open   | +---------+------------------------+-------+

if want 1 row each filename, reflecting specific states , listing recent date friend:

select filename ,        status   ,        max_date = max( dates ) some_table t group filename , status having status = '<your-desired-status-here>'
