sparql query to delete

Question

I am writing a sparql query in java to delete rdf data with a specific id. I am trying with

Delete ?ID ?name Where { 
     ?ID rdf:type ex:example ex:name ?name 
     FILTER(?ID ="something") 
}

but it doesn't do anything. Does anyone knows what is my mistake?

Answer 1

That query is probably failing, the closer SPARQL query that might work is ...

DELETE WHERE { 
     ?id rdf:type ex:example;
         ex:name ?name .
     FILTER(?id = <http://foo.com/some/example/uri>) 
}

The var ?id cannot be a string since it is positioned as a subject and in RDF all subjects are IRIs, not literals.

If you post some sample data we might be able to help better.
