DbiDate object

[revuesbio]

Hi all

I am using odbc to connect to Microsoft Access DB.  When I send a
request with a datetime column from the database, odbc returns
something called a DbiDate object.
ex  :
>>> x=data[0][2]
<DbiDate object at 0x009C4140>
>>> print x
Fri Apr 20 07:27:45 2007

I would like to select columns where datetime ("DbiDate column") is >
yesterday date.
and i don't understand how to send request with this DbiDate.

Could you help me ?
thank you
