New description:
Two Oracle specific failures have been introduced lately:
- Inability to deal with "%" in table or other identifier names (present
in 1.5a1)
- Oracle not working correctly for select_related cases where the
related model is null but contains character fields (master only)
The first of the failures happens because Oracle backend does querystr %
args formatting and if a table name contains '%' then the formatting will
fail.
The second one happens because we check for if all fetched columns are
None then set related object to None in models/query.py when creating the
related objects. Due to a recent change we correctly convert the row
values in compiler.py for related select fields, too. This means that None
values will be converted to "" and the check in models/query.py fails.
