如何在sqlalchemy中生成此查询？

pip install sqlalchemy

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

Base = declarative_base()

class User(Base):
    __tablename__ = 'users'
    id = Column(Integer, Sequence('user_id_seq'), primary_key=True)
    name = Column(String(50))
    age = Column(Integer)

engine = create_engine('sqlite:///users.db')
Base.metadata.create_all(engine)
Session = sessionmaker(bind=engine)

session = Session()

# 查询所有用户
users = session.query(User).all()

# 按条件查询
users = session.query(User).filter(User.age > 18).all()

# 按条件查询并排序
users = session.query(User).filter(User.age > 18).order_by(User.name.asc()).all()

# 按条件查询并分页
users = session.query(User).filter(User.age > 18).order_by(User.name.asc()).offset(0).limit(10).all()
