dZRS(
saAn operation encountered database state that is unaccounted for.

    Conditions which cause this to happen include:

    * A flush may have attempted to update or delete rows
      and an unexpected number of rows were matched during
      the UPDATE or DELETE statement.   Note that when
      version_id_col is used, rows in UPDATE or DELETE statements
      are also matched against the current known version
      identifier.

    * A mapped object with version_id_col was refreshed,
      and the version number coming back from the database does
      not match that of the object itself.

    * A object is detached from its parent object, however
      the object was previously attached to a different parent
      identity which was garbage collected, and a decision
      cannot be made if the new parent was really the most
      recent "parent".

Zd�ZRS(s�A refresh operation failed to retrieve the database
    row corresponding to an object's known primary key identity.

    A refresh operation proceeds when an expired attribute is
    accessed on an object, or when :meth:`.Query.get` is
    used to retrieve an object which is, upon retrieval, detected
    as expired.   A SELECT is emitted for the target row
    based on primary key; if no row is returned, this
    exception is raised.

    The true meaning of this exception is simply that
    no row exists for the primary key identifier associated
    with a persistent object.   The row may have been
    deleted, or in some cases the primary key updated
    to a new value, outside of the ORM's management of the target
    object.
