#创建对象的基类：
Base = declarative_base()
 
#定义User对象：
class User(Base):
    #表的名字：
    __tablename__ = 'user'
 
    #表的结构:
    userid = Column(Integer,primary_key=True)
    username = Column(String(20))
    age = Column(Integer)
    department = Column(String(20))
 
#初始化数据库连接
engine = create_engine("mysql+pymysql://kang:[email protected]/test",encoding="utf-8")
 
#创建session类型
DBSession = sessionmaker(bind=engine)
 
#创建session对象
session = DBSession()
 
#先查询，后删除
session.query(User).filter(User.username == "Jack").delete()
session.commit()
