You just create a selectable and then can it use like a table object in
SQLAlchemy. Like this.
-- Gerhard
from sqlalchemy import *
engine = create_engine("sqlite:///:memory:")
metadata = MetaData(engine)
user = Table("person", metadata,
Column("person_id", Integer, primary_key=True),
Column("firstname", String(20), nullable=False),
Column("age", Integer, nullable=False),
)
metadata.create_all()
user.insert().execute(firstname="Gerhard", age=31)
user.insert().execute(firstname="Lara", age=47)
user.insert().execute(firstname="Benny", age=13)
adults = user.select(user.c.age >= 18)
print adults.select().execute().fetchall()
