You can do this from a SQL query using SEM_MATCH table function which allows you to specify a SPARQL graph pattern.
SEM_MATCH retrieves relevant data from the RDF store which can then be joined with one or more relational tables.
For more details on use of SEM_MATCH, please refer to documentation at:
I am using Jena & SparQL. I am not sure if i can call SEM_MATCH query directly from Jena. As per my understanding Sparql gets converted to SEM_MATCH query.
As i am calling Sparql query using Jena, I want to use RDBMS table data also with sparql query in a single query.
If possible , kindly share an example , it would be of great help
Thanks and Regards,

Use of SPARQL from Jena does not currently allow access to relational tables. A workaround you may consider trying would be to first generate RDF triples from the relational tables and then try querying using SPARQL the original RDF data plus the RDF data generated from relational tables.
