In some rare cases, you might wish to pass parameters to the SQL
fragments in ``extra(select=...)``. For this purpose, use the
``select_params`` parameter. Since ``select_params`` is a sequence and
the ``select`` attribute is a dictionary, some care is required so that
the parameters are matched up correctly with the extra select pieces.
In this situation, you should use a :class:`collections.OrderedDict` for
the ``select`` value, not just a normal Python dictionary.
``select_params`` parameter.
This will work, for example::
Blog.objects.extra(
select=OrderedDict([('a', '%s'), ('b', '%s')]),
select_params=('one', 'two'))
select={'a': '%s', 'b': '%s'},
select_params=('one', 'two'),
)
If you need to use a literal ``%s`` inside your select string, use
the sequence ``%%s``.
