bliss.run("CREATE TABLE contributors (firstname VARCHAR, lastname VARCHAR)")
bliss.run("INSERT INTO contributors VALUES (?, ?)", [('Andrew', 'Kuchling'),
                                                     ('James', 'Henstridge'),
                                                     ('Daniele', 'Varrazzo'),
                                                     ('Marc-Andre', 'Lemburg')])

print bliss.one("SELECT firstname FROM contributors WHERE lastname='Lemburg'")
# Marc-Andre

print bliss.all("SELECT firstname FROM contributors")
# [u'Andrew', u'James', u'Daniele', u'Marc-Andre']

print bliss.all("SELECT firstname, LENGTH(lastname) AS length FROM contributors")
'''
 [Record(firstname=u'Andrew', length=8),
  Record(firstname=u'James', length=10),
  Record(firstname=u'Daniele', length=8),
  Record(firstname=u'Marc-Andre', length=7)]
