Classe « ColumnOperators »

Méthode sqlalchemy.ColumnOperators.not_in

Signature de la méthode not_in

def not_in(self, other: 'Any') -> 'ColumnOperators' 

Description

help(ColumnOperators.not_in)

implement the ``NOT IN`` operator.

This is equivalent to using negation with
:meth:`.ColumnOperators.in_`, i.e. ``~x.in_(y)``.

In the case that ``other`` is an empty sequence, the compiler
produces an "empty not in" expression.   This defaults to the
expression "1 = 1" to produce true in all cases.  The
:paramref:`_sa.create_engine.empty_in_strategy` may be used to
alter this behavior.

.. versionchanged:: 1.4 The ``not_in()`` operator is renamed from
   ``notin_()`` in previous releases.  The previous name remains
   available for backwards compatibility.

.. versionchanged:: 1.2  The :meth:`.ColumnOperators.in_` and
   :meth:`.ColumnOperators.not_in` operators
   now produce a "static" expression for an empty IN sequence
   by default.

.. seealso::

    :meth:`.ColumnOperators.in_`
