There are two scenarios where this error occurs: * In a Session flush operation, if two objects are mutually dependent on each other, they can not be inserted or deleted via INSERT or DELETE statements alone; an UPDATE will be needed to post-associate or pre-deassociate one of the foreign key constrained values. The ``post_update`` flag described at :ref:`post_update` can resolve this cycle. * In a :attr:`_schema.MetaData.sorted_tables` operation, two :class:`_schema.ForeignKey` or :class:`_schema.ForeignKeyConstraint` objects mutually refer to each other. Apply the ``use_alter=True`` flag to one or both, see :ref:`use_alter`.

This error is raised and consumed internally by a connection pool. It can be raised by the :meth:`_events.PoolEvents.checkout` event so that the host pool forces a retry; the exception will be caught three times in a row before the pool gives up and raises :class:`~sqlalchemy.exc.InvalidRequestError` regarding the connection attempt.

A subclass of :class:`_exc.DisconnectionError` that indicates that the disconnect situation encountered on the connection probably means the entire pool should be invalidated, as the database has been restarted.

Wraps exceptions raised by the DB-API underlying the database operation. Driver-specific implementations of the standard DB-API exception types are wrapped by matching sub-types of SQLAlchemy's :class:`DBAPIError` when possible. DB-API's ``Error`` type maps to :class:`DBAPIError` in SQLAlchemy, otherwise the names are identical. Note that there is no guarantee that different DB-API implementations will raise the same exception type for any given error condition. :class:`DBAPIError` features :attr:`~.StatementError.statement` and :attr:`~.StatementError.params` attributes which supply context regarding the specifics of the statement which had an issue, for the typical case when the error was raised within the context of emitting a SQL statement. The wrapped exception object is available in the :attr:`~.StatementError.orig` attribute. Its type and properties are DB-API implementation specific.
