[Virtuoso-users] Permission to execute a "SPARUL_CLEAR"?

[Bob DuCharme]

I tried to execute a "clear graph" command as shown at the end of 15.4.3 
at http://docs.openlinksw.com/virtuoso/rdfsparul.html and got this:

 42000 Error SR186: No permission to execute procedure DB.DBA.SPARUL_CLEAR.
When I go to the Edit Grants of [username] screen in the Conductor and 
pick Show All, it looks like there  are dozens and dozens of named 
permissions to grant, many with very cryptic names. What do I need to 
grant an account to enable it to clear graphs with a SPARUL query?

thanks,

Bob
