Turn the data into nice types, with pg you might get PgInt types from your data, and each row of the database is in a special list & dict type allowing numeric or nomical access the value of each column. Easy way: tosend = [] for row in data: newRow = tuple([str(item) for item in row]) tosend.append(newRow) Better way? Surposing your data is returned as an int, a date/time, an interval (mx.datetimedelta) and a string... tosend = [] for myint, mydate, mydelta, mystr in data: tosend.append((int(myint), packageDate(mydate), packageDateTimeDelta(mydelta), str(mystr))) def packageDate(d): return d.year, d.month, d.day, d.hour, d.minute, d.second def unpackageDate(d): from mx.DateTime import DateTime return DateTime(*d) I will leave the rest as an exercise for the reader.
