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/Enterprise) 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?
Solution variance can be as a result of the Virtuoso Anytime Query feature and timeout settings in your INI.
