[Tutor] pyodbc/date values in MS Access

[Albert-Jan Roskam]

Hi,

Sorry for the late reply, but thanks a lot for helping me. It's solved now. 
Peter, the link you posted in another thread (or should I say 'query') was also 
relevant AND funny (http://xkcd.com/327/)

Merry Christmas and Happy Coding! *)

 Cheers!!
Albert-Jan

(1) Try providing the date in ISO format "yyyy-mm-dd"

"2010-01-01"

or (even better if supported) as a date value

from datetime import date
date(2010, 1, 1)

(2) Wrap the value into a tuple which I think is required by the Python 
DBAPI.

cursor.execute(sql, ("2010-01-01",))
cursor.execute(sql, (date(2010, 1, 1),))
