---+Virtuoso SPARQL 1.1. VALUES Usage Examples 


---++What?
This guide contains Virtuoso SPARQL 1.1. VALUES Usage example queries which you can run against 
any SPARQL endpoint that supports SPARQL 1.1 and the ability to allow a verified user perform 
INSERT operations. 

---++Why?
SPARQL 1.1 provides a mechanism for inline incorporation of Data as part SPARQL query patterns. 

---++How?

Here are some examples showcasing Virtuoso's support for this functionality:

   1 Assume the following statement for inserting triples INTO DBMS or Store:
<verbatim>      
PREFIX :     <http://example.org/book/> 
PREFIX ns:   <http://example.org/ns#> 

INSERT 
  { 
    GRAPH <urn:sparql:bind:tests> 
      {
        :book1  <http://purl.org/dc/elements/1.1/title> "SPARQL Tutorial" . 
        :book1  ns:price                                42 . 
        :book1  ns:discount                             0.2 . 
        :book2  <http://purl.org/dc/elements/1.1/title> "The Semantic Web" . 
        :book2  ns:price                                23 . 
        :book2  ns:discount                             0.25 . 
      }
  }
</verbatim>
   1 From a Virtuoso SPARQL Endpoint ( http://host:port/sparql  ) query the graph by executing the query from below for ex.:
<verbatim>   
PREFIX :     <http://example.org/book/> 
PREFIX ns:   <http://example.org/ns#> 

SELECT ?book ?title ?price  
FROM <urn:sparql:bind:tests>  
WHERE 
  {  
    VALUES ?book { :book1 :book3 } 
    ?book <http://purl.org/dc/elements/1.1/title> ?title ; 
                                         ns:price ?price . 
  }
</verbatim>

      1 [[http://bit.ly/1i75jDz][View the SPARQL Query Results via SPARQL Protocol URL]];
   1 Alternative variant of the query:
<verbatim>
PREFIX :     <http://example.org/book/> 
PREFIX ns:   <http://example.org/ns#> 

SELECT ?book ?title ?price 
FROM <urn:sparql:bind:tests> 
WHERE
  {
    ?book <http://purl.org/dc/elements/1.1/title> ?title ; 
                                         ns:price ?price . 
    VALUES (?book ?title) 
    { (UNDEF "SPARQL Tutorial") 
      (:book2 UNDEF) 
    } 
  }
</verbatim>
      1 [[http://bit.ly/1fRt1Dz][View the SPARQL Query Definition via SPARQL Protocol URL]];
