The answer is no, unless the person who holds the rights to the BY-SA
work explicitly chooses to separately licence it under the ODbL.

This is because BY-SA is a copyleft licence and so it doesn't allow the
work or its derivatives to be placed under another licence.

Data from an ODbL database may however be used to create a BY-SA
Produced Work.
