Thank you Jonatan. func.DATE() works.
I've opened an issue sqlalchemy/sqlalchemy#5104

Hi guys,
For SQLite, I'm using the func.DATE() function:

from sqlalchemy import func

session.query(db.Transaction).filter(func.DATE(db.Transaction.datetime) == date.today())

It worked! Thank you sooo much!

This worked for me:

from sqlalchemy import func
table_db = Youtable.query.filter(func.DATE(Youtable.date_bd) == your_date)
