I feel obliged to point out that there ARE no rows meeting the criteria 
you query specified!

mysql> SELECT expire_date, NOW() FROM amember_payments;
+-------------+---------------------+
| expire_date | NOW()               |
+-------------+---------------------+
| 2004-10-21  | 2007-05-27 15:59:21 |
| 2004-11-21  | 2007-05-27 15:59:21 |
+-------------+---------------------+
2 rows in set (0.02 sec)

mysql>

So I am not sure how you managed to get a manual query to work, but do 
be sure that the Python query you mentioned at the start of the thread

             sql = """SELECT payment_id FROM amember_payments WHERE
member_id=%s AND expire_date > NOW() AND completed=1 AND (product_id
 > >11 AND product_id <21)""", (self.uid)

doesn't stand a chance of returning any results unless you use a time 
machine to go back almost three years!
