Why is DAL returning a tuple here?
>>> from dal import DAL
>>> db = DAL('postgres://web2pyuser:password@localhost:5432/webtest',
fake_migrate_all=True)
>>> q = '''select coalesce(sum(amount), 0) from product_journal'''
>>> db.executesql(q)
[(Decimal('250.000'),)] # Why is the returned value a tuple? This does not
seem to make sense.
>>> q = '''select coalesce(sum(amount), 0) from product_journal where
product_id = 255'''
>>> db.executesql(q)
[(Decimal('0'),)]
Is this the way it's supposed to work and will it stay this way?
