Informix live query with selection on datetime field

Hello,

I try to put a select statement on a datetime field.
When Requestlive:=False, the next lines are OK:
  select * from Table where date(datetimefield) = "01/31/2001"
  select * from Table where datetimefield = DATETIME(2001-01-31) YEAR TO DAY
  select * from Table where datetimefield = MDY(01,31,2001)

I would like to put such a selection on a live query.
Anyone ideas?
