I'm using the following SPARQL query DELETE DATA { } ;

After I executing the following lines, Model model = ModelFactory.createDefaultModel(); UpdateAction.parseExecute(sparqlUpdateQuery, model);

my model is still empty. I am trying to execute the query on unnamed graph. I'm new to Jena, please guide.

  • Without seeing data, more code and query, it's impossible to give any helpful answer. For Jena, there exists a very good documentation, also with tutorials. – UninformedUser Jun 12 '16 at 19:20

    And if you DELETE something from an empty Jena model, what do you expect instead of an empty model as result? – UninformedUser Jun 12 '16 at 19:21
