我是sql炼金术的新手, 考虑您有以下两个表定义:
class Persons(Base):
__tablename__ = 'persons'
id = Column(INTEGER, primary_key =True)
first_name = Column(String(10))
last_name = Column(String(10))
zip_code = Column(Integer)
class Addresses(Base):
__tablename__ = 'addresses'
ad_id = Column(INTEGER, primary_key =True)
name = Column(String(10))
zip_id = Column(Integer, ForeignKey('persons.zip_code'))
