Hi Eugene,
You can perform multiple insert/delete commands against Virtuoso as detailed at:
http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtTipsAndTricksGuideSPARQLSingleMultipleExecution
Although note you have to execute against an endpoint with read/write access,
which /sparql does not have by default so I suspect you were getting an error
of the form:
Virtuoso 42000 Error SR186: No permission to execute procedure
DB.DBA.SPARQL_DELETE_DICT_CONTENT with user ID 106, group ID 106
So you have to run against the /sparql-auth endpoint which challenges you for
authentication and will then allow you to perform write operations, see the
following docs for more details:
