  * LOB columns may not be used in a ``SELECT DISTINCT`` list. This means that

    attempting to use the ``QuerySet.distinct`` method on a model that

    includes ``TextField`` columns will result in an error when run against

    Oracle. A workaround to this is to keep ``TextField`` columns out of any

    models that you foresee performing ``distinct()`` queries on, and to

    include the ``TextField`` in a related model instead.

    with ``distinct()`` to prevent ``TextField`` columns from being included in

    the ``SELECT DISTINCT`` list.
