Méthode sqlalchemy.orm.Query.slice

Signature de la méthode slice

def slice(self, start, stop) 

Description

slice.__doc__

Computes the "slice" of the :class:`_query.Query` represented by
        the given indices and returns the resulting :class:`_query.Query`.

        The start and stop indices behave like the argument to Python's
        built-in :func:`range` function. This method provides an
        alternative to using ``LIMIT``/``OFFSET`` to get a slice of the
        query.

        For example, ::

            session.query(User).order_by(User.id).slice(1, 3)

        renders as

        .. sourcecode:: sql

           SELECT users.id AS users_id,
                  users.name AS users_name
           FROM users ORDER BY users.id
           LIMIT ? OFFSET ?
           (2, 1)

        .. seealso::

           :meth:`_query.Query.limit`

           :meth:`_query.Query.offset`
