Examples of execSelect()

com.hp.hpl.jena.query.QueryExecution.execSelect()
Execute a SELECT query
Important: The name of this method is somewhat of a misnomer in that depending on the underlying implementation this typically does not execute the SELECT query but rather answers a wrapper over an internal data structure that can be used to answer the query. In essence calling this method only returns a plan for executing this query which only gets evaluated when you actually start iterating over the results.
