how to return triple (was "row") number in SPARQL?

Can I return the triple number in SPARQL query?

For example, in Oracle database we can do this with rownum pseudo-column or ROW_NUMBER() function.

So how to query it in SPARQL from DBpedia, for example?

We can count triples by using count(*) or count(?var_name) function in SPARQL, but how to display an incremental number for each triple in SPARQL query? Is it possible?

No, it is not possible because SPARQL is designed to query RDF graphs, and RDF graphs are not tables. Hence there is no concept of a row - instead data is represented by subject, object, predicate triples representing a graph.

A SPARQL SELECT statement does return a result set that is basically a row for each query match, but that's different than representing the data in rows.
