    query pattern for SDO_RDF_MATCH

      What form of query can be found in the first SDO_RDF_MATCH function parameter?
      In SPARQL it is possible to use in OPTIONAL keyword, for example

      SELECT ?x ?y ?z
      ?x test:value ?y OPTIONAL {  ?y test:hasIncome ?z }

      I will be given in the result the records which has both triples, but also those for which te second triple is not set. Is it possible to get the same effect in Oracle?

      Thanks for answer.
