Signature de la méthode filter

def filter(self, *criterion) 

Description

filter.__doc__

Apply the given filtering criterion to a copy
        of this :class:`_query.Query`, using SQL expressions.

        e.g.::

            session.query(MyClass).filter(MyClass.name == 'some name')

        Multiple criteria may be specified as comma separated; the effect
        is that they will be joined together using the :func:`.and_`
        function::

            session.query(MyClass).\
                filter(MyClass.name == 'some name', MyClass.id > 5)

        The criterion is any SQL expression object applicable to the
        WHERE clause of a select.   String expressions are coerced
        into SQL expression constructs via the :func:`_expression.text`
        construct.

            :meth:`_query.Query.filter_by` - filter on keyword expressions.
