How to store RDF data direct to sesame using D2R?

I am looking for any solution, to store my RDFized data direct to sesame through Java program. I have a database of 1.7 M records, i used D2R to transform it into RDF. Now i want to store RDFized data into sesame triple store. I did not generate RDF dump because data was huge. Is there any way code/solution through which i can shift my RDFized data into my triple store. Thanks

I believe what you're really trying to say is: you have a large RDBMS over which you've created an RDF wrapper view using D2RQ. Now you want to extract that data using SNORQL (D2RQ's SPARQL endpoint) and push it to a native RDF triple store using Sesame.

I tried to edit your question to reflect that but unfortunately it got voted down.

Anyway, in Sesame, you can do this through Java code by:

  1. firing a Graph Query that will return you a GraphQueryResult

    GraphQueryResult graphResult = con.prepareGraphQuery(
QueryLanguage.SPARQL, "CONSTRUCT <...your SPARQL QUERY here ...>".evaluate();

  2. use the QueryResults utility class to return the Statements as a Model:

    Model resultModel = QueryResults.asModel(graphQueryResult);

  3. use one of the overloaded RepositoryConnection.add methods to add this data to a native Sesame store.
