Return a :class:`_engine.Connection` object corresponding to this
:class:`.Session` object's transactional state.
If this :class:`.Session` is configured with ``autocommit=False``,
either the :class:`_engine.Connection` corresponding to the current
transaction is returned, or if no transaction is in progress, a new
one is begun and the :class:`_engine.Connection`
returned (note that no
transactional state is established with the DBAPI until the first
SQL statement is emitted).
Alternatively, if this :class:`.Session` is configured with
``autocommit=True``, an ad-hoc :class:`_engine.Connection` is returned
using :meth:`_engine.Engine.connect` on the underlying
:class:`_engine.Engine`.
Ambiguity in multi-bind or unbound :class:`.Session` objects can be
resolved through any of the optional keyword arguments. This
ultimately makes usage of the :meth:`.get_bind` method for resolution.
:param bind_arguments: dictionary of bind arguments. May include
"mapper", "bind", "clause", other custom arguments that are passed
to :meth:`.Session.get_bind`.
:param bind:
deprecated; use bind_arguments
:param mapper:
deprecated; use bind_arguments
:param clause:
deprecated; use bind_arguments
:param close_with_result: Passed to :meth:`_engine.Engine.connect`,
indicating the :class:`_engine.Connection` should be considered
"single use", automatically closing when the first result set is
closed. This flag only has an effect if this :class:`.Session` is
configured with ``autocommit=True`` and does not already have a
transaction in progress.
.. deprecated:: 1.4 this parameter is deprecated and will be removed
in SQLAlchemy 2.0
:param execution_options: a dictionary of execution options that will
be passed to :meth:`_engine.Connection.execution_options`, **when the
connection is first procured only**. If the connection is already
present within the :class:`.Session`, a warning is emitted and
the arguments are ignored.

:ref:`session_transaction_isolation`
:param \**kw:
deprecated; use bind_arguments
