Sql server SQLServer和外键/主键中的SQLAlchemy声明性模式

我正在努力创建属于SQL Server数据库中架构的表，并确保主键/外键正常工作

---

我正在寻找一些代码示例来说明这是如何实现的

实现这一点所需的成分是

\uuu table\u args\uuuu

以及在

外键上使用模式前缀

DBSession = sessionmaker(bind=engine)
session = DBSession()

from sqlalchemy import Column, Integer, String
from sqlalchemy.orm import relationship

Base = declarative_base()

class Table1(Base):
    __tablename__ = 'table1'
    __table_args__ = {"schema": 'my_schema'}

    id = Column(Integer,primary_key = True)
    col1 = Column(String(150))
    col2 = Column(String(100))

    reviews = relationship("Table2", cascade = "delete")  

class Table2(Base):
    __tablename__ = 'table2'
    __table_args__ = {"schema": 'my_schema'}

    id = Column(Integer,primary_key = True)
    key = Column(Integer)
    col2 = Column(String(100))



    key = Column(Integer, ForeignKey("my_schema.table1.id"), index=True)  
    premise = relationship("Table1") 


Base.metadata.create_all(bind=engine)
