#創(chuàng)建對象的基類：
Base = declarative_base()

#定義User對象：
class User(Base):
    #表的名字：
    __tablename__ = 'user'

    #表的結(jié)構(gòu):
    userid = Column(Integer,primary_key=True)

    department = Column(String(20))

#初始化數(shù)據(jù)庫連接

#創(chuàng)建session類型
DBSession = sessionmaker(bind=engine)

#創(chuàng)建session對象
session = DBSession()

#創(chuàng)建新的user對象

#添加單條數(shù)據(jù)
#session.add(new_user1)

#添加到session
session.add_all([new_user1,new_user2,new_user3])

#提交即保存到數(shù)據(jù)庫
session.commit()

#關(guān)閉session
session.close()
