SqlAlchemy:使用不等于条件连接两个表

from sqlalchemy import create_engine, Column, Integer, String
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base

# 创建数据库引擎
engine = create_engine('数据库连接字符串')

# 创建会话工厂
Session = sessionmaker(bind=engine)
session = Session()

# 创建基类
Base = declarative_base()

# 定义表模型
class User(Base):
    __tablename__ = 'users'
    id = Column(Integer, primary_key=True)
    name = Column(String)
    # ...

class Product(Base):
    __tablename__ = 'products'
    id = Column(Integer, primary_key=True)
    name = Column(String)
    # ...

# 查询不等于条件连接两个表
result = session.query(User, Product).filter(User.id != Product.id).all()

# 打印结果
for user, product in result:
    print(user.name, product.name)
