[Virtuoso-users] merge named graphs

[Sergio Fernandez Lopez]

Hi,

is there any fast way to merge some named graph in a new one?

I can do it with a simple query such as:

  INSERT INTO GRAPH <http://localhost/merged> {
    ?s ?p ?o
  }
  FROM <http://localhost/g1>
  FROM <http://localhost/g2>
  FROM <http://localhost/gn>
  WHERE {
    ?s ?p ?o
  }

But I'm sure if should be exist a more efficient way to do it.

Cheers,
