[Virtuoso-users] Delete from SPARQL Endpoint

[Chuck Borromeo]

Hi,
  I am trying to delete a triple from my local machine.  I am running 
Virtuoso 5.0.6.  I am executing the following SPARQL statement from the 
SPARQL endpoint:

delete from graph <http://xyz>
 {   <testURI>  <hasProperty>  <http://testnode> }

I got the following error when I ran on my localhost.  It sounds like a 
permissions error:

42000 Error SR186: No permission to execute procedure 
DB.DBA.SPARQL_DELETE_DICT_CONTENT.

SPARQL query:
define sql:signal-void-variables 1 define output:valmode "LONG" delete 
from graph <http://xyz>
 {   <testURI>  <hasNeuroML>  <http://testnode> }

I was not able to find the Procedure DB.DBA.SPARQL_DELETE_DICT_CONTENT 
in Conductor.  How do I execute a delete through the SPARQL endpoint?

Thanks,
Chuck
