[redland-dev] Rasqal query to insert elements

[Shashank Bandari]

Hi,
 I am trying to use rasqal to use SPARQL1.1 queries to insert a
triple into the data graph. However when I retrieve the triple using
SELECT, I do not get the inserted triple. Could someone send me a sample
code to insert triples into the data graph.

The part of the code
written by me to insert the triple is as follows

 rasqal_query *tquery;


 query_string="PREFIX cim: 
 PREFIX rdf: 
 PREFIX base: 
 INSERT DATA
{base:" +name +" rdf:type cim:GeographicalRegion .}"; 


tquery=rasqal_new_query(rql_world,"sparql11",NULL);
 int res=
rasqal_query_add_data_graph(tquery,data_graph);

rasqal_query_prepare(tquery,(const unsigned
char*)query_string.c_str(),NULL);

results=rasqal_query_execute(tquery);
 rasqal_free_query(tquery);  

Is
it the right way to insert the triple?
