问题遇到的现象和发生背景
天天基金网获取基金数据来分析 数据库连接
用代码块功能插入代码，请勿粘贴截图
初始化数据库连接:
engine = create_engine(
"postgresql+psycopg2://username:'ncxcdb',passwd:'78265503_QQcom',@47.100.38.198:5433/dbf5d2d80675b44e41ac30430f974d0c0fncxcbd")
创建DBSession类型:
DBSession = sessionmaker(bind=engine)
创建表结构
Base.metadata.create_all(engine)
运行结果及报错内容
