Example Code

class Orders(SQLModel, table=True):
    id: Optional[int] = Field(default=None, primary_key=True)
    order_number: str
    item_name: str
    item_price: float

Description

I have a model named Orders, where I need to implement PostgreSQL sequence which will generate an auto-increment alphanumeric order number. I tried searching but no luck on how to implement in SqlModel. I have found it for SqlAlchemy but don't know how to do in SqlModel.

You can try sa_column_args and sa_column_kwargs, which will be appended to the generated SQLAlchemy column.
