Hello, as always I would be grateful if someone could help me with the following questions..
1) While in isql I cannot display previous commands in history. The up key button shows the famous ^[[A string. This happens only in isql. In the terminal I can see the previous commands using the referred key button. Is it possible to solve this? I think this is quite critical for me... 2) How do I delete a graph (not just delete all the triples from it) ? The old command (i.e., sparql delete graph <>) probable does not work anymore. The other command: soarql drop graph <>) gives me this message: *** Error 22023: [Virtuoso Driver][Virtuoso Server]SPARUL_DROP() failed: graph <http://....com> has not been explicitly created before What is the difference for an explicit graph? This choice also exists in the conductor interface. 3) How to show all the graphs? When I use: sparql select distinct ?g where{graph ?g {?s ?p ?o}}; gives me no result. However, the query: sparql select count(distinct ?g) where{graph ?g {?s ?p ?o}}; gives me 8. The conductor also shows correctly my graphs. Thank you.
