Example Code

from sqlalchemy import func

selectable = people.tablesample(
            func.bernoulli(1),
            name='alias',
            seed=func.random())
stmt = select(selectable.c.people_id)

Description

I'm trying to use the tablesample method defined in SQLAlchemy, but I can't seem to understand how to migrate it's structure from the sample code into SQLModel code.
For more context, I'm trying to get a random sample from a simple select query (with two wheres) and would prefere to do everything in the query instead of having to sample the resulting data (cause the table is really large)
