SQLAlchemy query to return only n results?

问题

I have been googling and reading through the SQLAlchemy documentation but haven't found what I am looking for.

I am looking for a function in SQLAlchemy that limits the number of results returned by a query to a certain number, for example: 5? Something like first() or all().

回答1:

for sqlalchemy >= 1.0.13 Use the limit method.

query.(Model).filter(something).limit(5).all()

回答2:

Alternative syntax

query.(Model).filter(something)[:5].all()

回答3:

In my case it works like

def get_members():
    m = Member.query[:30]
    return m
