Hi friends!
For this code:
from sqlalchemy import *
import MySQLdb
def connect(user, passwd, dbname, host):
return MySQLdb.connect(user=user, passwd=passwd,
db=dbname, host=host)
if __name__ == '__main__':
db = create_engine('mysql://', creator=connect('user', 'pass',
'demo',
'192.168.1.2'))
db.echo = True
metadata = BoundMetaData(db)
users = Table('users', metadata,
Column('user_id', Integer, primary_key=True),
Column('name', String(40)),
Column('age', Integer),
)
users.create()
emails = Table('emails', metadata,
Column('email_id', Integer, primary_key=True),
Column('address', String),
Column('user_id', Integer, ForeignKey('users.user_id')),
)
emails.create()
I recive following error:
