Thanks for your rapid response...
For the example,
I have do this query in my endpoint server "OpenRDF Workbench 2.3.1"..
This is the jena users list - this is a Sesame question as it's the
server that is not supporting COUNT. They have their own mailing lists.
But the answer is that Sesame 2.3.1 does not have support for SPARQL
1.1. Only the very recent release of 2..4.0 has any SPARQL 1.1 support.
2.3.1 is quite old anyway (2010-02).
Jena parses the query locally before sendning to check for error but it
is the SPARQL 1.1 parser so it lets through the query then the server
rejects it.

String queryStrAtt =
"SELECT (COUNT(?p) AS ?nbRows)
WHERE
{
?s<http://www.w3.org/1999/02/22-rdf-syntax-ns#type>
<http://purl.org/ontology/mo/Record>.
?s ?p ?o
}"
Query queryAtt =
QueryFactory.create(queryStrAtt,Syntax.defaultQuerySyntax);
QueryExecution qeAtt =
QueryExecutionFactory.sparqlService("http://xxxx/openrdf-sesame/repositories/xxxx";,
queryAtt);
ResultSet nbRows = qe.execSelect();
All i want to do is to count the total of rows of my datasets RDF, which
is in the resource "Record"...
And the problem is, the server doesnt know the function "COUNT"...
How is the solution for this?

Objet : Re: [Newbie] How to use function "COUNT" in ARQ 2.8.7 ?
Please send questions to the user list.
Also note:
----------
The Jena user list is moving to Apache.
The list name is 'jena-users' and the mail server is 'incubator.apache.org'.
