把MySQL表结构映射为Python中的对象的教程

class User(object):
  def __init__(self, id, name):
    self.id = id
    self.name = name

[ 
User(‘1‘, ‘huangyi‘),
 
User(‘2‘, ‘letian‘),
 
User(‘3‘, ‘xiaosi‘)
]

from sqlalchemy import Column, String, create_engine
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base
 
Base = declarative_base()
 
class User(Base):
  __tablename__ = ‘user‘
  id = Column(String(20), primary_key=True)
  name = Column(String(20))
 
engine = create_engine(‘mysql+mysqlconnector://root:XXXXX@localhost:3306/TUZHI‘)
DBSession = sessionmaker(bind=engine)
 
session = DBSession()
new_user = User(id=‘4‘, name=‘Huangyi‘)
session.add(new_user)
session.commit()
#session.close()
 
##进行查询
#session = DBSession()
user = session.query(User).filter(User.id==‘4‘).one()
print ‘type:‘, type(user)
print ‘name:‘, user.name
session.close()
