No results found in sparql endpoint

[haklaekim]

Hi,

I have installed and stored rdf data into store. After loading a sparql endpoint, it gives "no results found" when a default query is executed as followed.

SELECT * WHERE {

  GRAPH ?g { ?s ?p ?o . }

}

LIMIT 10

This code is used. (it is same code in wiki).

What it is a problem?

with thanks,

haklae
