Hi All! I'm currently testing Virtuoso because we need a fast RDF store which can handle billions of triples for my company's several projects and it shows itself very well so far. However, I've found that several queries do not work as expected (neither through isql nor jdbc interface):
sparql insert into graph <http://my_graph> { <http://a> <http://b> "1"^^<http://www.w3.org/2001/XMLSchema#int> } sparql delete from graph <http://my_graph> { <http://a> <http://b> "1"^^<http://www.w3.org/2001/XMLSchema#int> } I think these queries are correct as they are very much like queries from sparul examples, but they do nothing. Please, help me to make them work! I'm using the demo database in var/lib/virtuoso/db with default configuration. Virtuoso version is 5.0.8, it is compiled from source and used on Debian lenny x86. Thanks in advance! -- Alexander
