When running syncdb, an ``ORA-06552`` error may be encountered if

certain Oracle keywords are used as the name of a model field or the

value of a ``db_column`` option.  Django quotes all identifiers used

in queries to prevent most such problems, but this error can still

occur when an Oracle datatype is used as a column name.  In

particular, take care to avoid using the names ``date``,

``timestamp``, ``number`` or ``float`` as a field name.
