What is the SPARQL query to get the name of all graphs existing in my triplestore?

Question

I want to get the name of all existing graphs in my Fuseki server, it should return a message with a list of all graphs name.

Answer 1

I have tried the answer given by Joshua Taylor in Virtuoso, but got nothing.

Maybe it's different between fuseki and virtuoso. So I provide a sparql for virtuoso users who just find the answer like me.

SELECT DISTINCT ?g 
WHERE {
  GRAPH ?g { ?s ?p ?o }
}

Answer 2

Without more context, we don't know whether you mean some additional metadata about the "name" of a graph, or what you mean exactly by "a message with a list of all graphs name", but it sounds like you might just want:

SELECT ?g 
WHERE {
  GRAPH ?g { }
}
