sparql级联删除个人

Question

i'm using Jena to interact with parliament triple store. The following sparql update query is to insert a new individual of a class Tenant i defined in my ontology:

PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX ex: <http://www.example.org/Example#>
INSERT DATA 
{
  ex:tenant1 a ex:Tenant;
               ex:hasName "admin";
               ex:hasStatus "Enabled".
}

where both hasName and hasStatus are two properties defined in this ontology. Then if i would delete ex:tenant1 individual, is there any way in sparqle to delete in cascade all the triples that has ex:tenant1 as subject? So, deleting only ex:tenant1 a ex:Tenant , i'd like to delete any references to it. I hope i was clear in explaining my problem and thanks you in advance for your help.

Answer 1

Sure. Just

PREFIX ex: <http://www.example.org/Example#>
DELETE WHERE { ex:tenant1 ?p ?o } 

This is based on the documentation:

3.1.3.3 DELETE WHERE

….

Example 11:

This example request removes all statements about anything with a given name of "Fred" from the default graph:

 PREFIX foaf: <http://xmlns.com/foaf/0.1/> DELETE WHERE { ?person foaf:givenName 'Fred'; ?property ?value }
