Example Code

class Xconnect(SQLModel, table=True):
    id: int = Field(primary_key=True)
    lvc: Optional[str] = Field(sa_column_kwargs={"unique": True})
    customer: int = Field(foreign_key="customer.id")
    region: int = Field(foreign_key="attr.id")

Description

Im trying to see if I can update the exisitng generated table Xconnect without deleting and recreating it,

for example, if I wantto make the Region field Optional, adding

region: Optional[int]

will not update the existing schema bcs the table is already created. How can I update the existing schema? Do I need to use Alembic for this?
