This is simple and works fine for me.

Lets say you have already connected to your database table and also got a cursor object. So following on on from that point.

import csv
curs = conn.cursor()
curs.execute("select * from oders")
m_dict = list(curs.fetchall())

with open("mycsvfile.csv", "wb") as f:
    w = csv.DictWriter(f, m_dict[0].keys())
    w.writerow(dict((fn,fn) for fn in m_dict[0].keys()))
    w.writerows(m_dict)
