If you are dealing with a DB API-compliant module then the return value from the cursor's execute method is undefined, and you need to call one of the "fetch" methods to extract the retrieved data. So you would want something like cursor.execute("SELECT isbn,price FROM books WHERE price IS NULL") rows = cursor.fetchall() for isbn, price in rows: print isbn, ":", price Once you get that working you can do your own computations with isbn and price. Note, however, that the specific query you use guarantees that the value of "proce" will be None, since you only retrieve the rows where price is NULL! > for row in rows: > > #Is this right? > for isbn in row: > > if isbn: > print "Found price = " + price > > connection.close(True) > regards Steve -- Steve Holden +1 571 484 6266 +1 800 494 3119 Holden Web LLC http://www.holdenweb.com/ -- http://mail.python.org/mailman/listinfo/python-list
