I want to query the SPARQL in the picture. But I found that some of the returned results in the first SPARQL is not contained in the returned results of the second SPARQL. I doubt that it is because of the setting parameters of virtuoso. Thanks a lot.
What Virtuoso product (open source or commercial) and version (virtuoso-t -? or virtuoso-iodbc-t -?) are you using ?
What application and interface are these queries being executed against ?
If you run the queries from the Virtuoso “isql” command line tool (prefixing them with the key word “SPARQL”) do they return the expected results ?
