It's a syntax error. Even when I try without DATE_FORMAT:
UDPATE activity SET activity_date = '2003-10-06 11:00:00', type_no = 1 WHERE activity_date =
'2003-06-10 11:15:00' AND type_no = 1;
Ah.
Perhaps spelling UDPATE as UPDATE will fix the problem. :-)

In that case, you don't need DATE_FORMAT() at all. Just compare activity_date
to the datetime value directly.
You still haven't indicated what you mean by the statement not working. It doesn't find any rows to update? Do you get any results from the following statement, which simply tests the comparison?
SELECT activity_date FROM activity
