from sqlmodel import SQLModel, Field
from typing import Optional

class MyModel(SQLModel, table=True):
id: Optional[int] = Field(default=None, primary_key=True)

class MyNextModel(MyModel):
name: str = Field(default="marvin")

Create instances for querying (similar to aliasing)

my_model_alias = MyModel(id=1)
my_next_model_alias = MyNextModel(id=2, name="Alice")

print(my_model_alias)
print(my_next_model_alias)

from sqlmodel.
