@ -669,9 +669,9 @@ some limitations on the usage of such LOB columns in general:
* 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.
Oracle. As a workaround, use the ``QuerySet.defer`` method in conjunction
with ``distinct()`` to prevent ``TextField`` columns from being included in
the ``SELECT DISTINCT`` list.
