網上很多代碼給的連接數據庫是連的sqlite的例子，按照以下方法寫沒問題，我還用了ORM

# -*- coding:utf-8 -*-
from sqlalchemy import create_engine,Column,Integer,String
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base

dbPath = 'sqlite:////Users/mbp/Downloads/JA.db'
engine = create_engine(dbPath,echo=True)
Session = sessionmaker(bind=engine)
session = Session()
Base = declarative_base()




class Actresses(Base):
    __tablename__ = 'JA_NAME'
    id = Column('id', Integer, primary_key=True, autoincrement=True)
    name = Column('NAME_URL',String)
    nameUrl = Column('NAME',String)

act = session.query(Actresses).all()
print act

如果有同學依葫蘆畫瓢把數據庫地址直接改成mysql的連接就會報錯

　raise EnvironmentError("%s not found" % (mysql_config.path,))

原因是使用sqlalchemy連接mysql的話光安裝sqlalchemy這個庫還不夠，還要安裝mysql-python這個驅動庫

裝好后，代碼中也不需要import，直接運行下就好了，完整代碼如下，重點就是在安裝了sqlalchemy之后還要再安裝下mysql-python
