raised as a result of DBAPI exceptions are all subclasses of
:exc:`.DBAPIError`.

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:`.MetaData.sorted_tables` operation, two :class:`.ForeignKey`
or :class:`.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:`.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.

r6 � s r6 c @ s e Zd ZdZdZdS )�InvalidatePoolErrora� Raised when the connection pool should invalidate all stale connections.
A subclass of :class:`.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.
This exception will be handled otherwise the same way as
:class:`.DisconnectionError`, allowing three attempts to reconnect
before giving up.

DontWrapMixina8 A mixin class which, when applied to a user-defined Exception class,
will not be wrapped inside of :exc:`.StatementError` if the error is
emitted within the process of executing a statement.
E.g.::
from sqlalchemy.exc import DontWrapMixin
class MyCustomException(Exception, DontWrapMixin):
pass
class MySpecialType(TypeDecorator):
impl = String
def process_bind_param(self, value, dialect):
if value == 'invalid':
raise MyCustomException("invalid!")

:class:`StatementError` wraps the exception raised
during execution, and features :attr:`.statement`
and :attr:`.params` attributes which supply context regarding
the specifics of the statement which had an issue.
The wrapped exception object is available in
the :attr:`.orig` attribute.

DBAPIErrora Raised when the execution of a database operation fails.
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.
