from flask import Flask
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///test.db'
db = SQLAlchemy(app)

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(50))
    age = db.Column(db.Integer)

# 查询年龄为18或者名字为"John"的用户
users = User.query.filter((User.age == 18) | (User.name == "John")).all()

for user in users:
    print(user.name, user.age)
