This is a common misconception. SPARQL can make queries over any RDF source, including RDF graphs that provide inferencing capabilities. For example in Jena, you can create graphs that take their asserted triples from a file, but then also return inferred triples when queried. Those inferences are often done on the fly, and on demand only.

SPARQL.
