sqlite3 backend does not allow '%i' in cursor.execute

[anonymous]

In file /usr/lib/python2.4/site-packages/django/db/backends/sqlite3/base.py is sais:

def convert_query(self, query, num_params):
    return query % tuple("?" * num_params)

This raises a TypeError in cases like: "SELECT * FROM table WHERE id = %i" % tuple("?" * 1), because '?' is no int.

A workaround for this special case could be

return query.replace('%i', '%s') % tuple("?" * num_params)

When does this occur? will this only happen when using custom SQL?
