# 1. 導入SQLAlchemy
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import Column, Integer, String


# 2.ORM 模型基類
Base = declarative_base() # 相當於Django model

# 3. 創建ORM對象
class User(Base):
    __tablename__ = ‘user‘
    id = Column(Integer, primary_key=True, autoincrement=True)
    name 
 
= Column(String(32), index=True)

# 4.創建數據庫連接

from sqlalchemy import create_engine
engine = create_engine(‘mysql+pymysql://root:[email protected]:3306/my_sqlalchemy?charset=utf8‘)

# 5.
# 去engine數據庫中創建所有繼承Base類的ORM對象
Base.metadata.create_all(engine)

SQLAlchemy的使用---數據庫的創建與連接
