Variable in updated schedule in SPARQL update

Question

Is it possible to use a variable to determine the graph (s) affected in the SPARQL update? For example, can I:

INSERT { GRAPH ?dest { ?person foaf:name ?name . ?person foaf:mbox ?email } } WHERE { GRAPH <http://example/people> { ?person foaf:name ?name . } } 

Answer 1

?dest should be determined by the WHERE (otherwise how does the system know where the data is in INSERT ?).

If you mean all the named graphs, add GRAPH ?dest {} to the WHERE .
