Mapping SPARQL to SQL

Do any of you know about or have been involved in work that maps SPARQL 
queries to SQL?
I'm assuming a Relational database that has been mapped virtually to 
RDF.  SPARQL Queries
on the RDF representation would need to be translated to SQL queries on 
the underlying Relational database.
