Hello I have a probably simple problem but I am not able to find it
anywhere in docs.

I use this code in Interactive SQL

SPARQL clear graph <http://product-open-data.org/temp>;
SPARQL clear graph <
http://linked.opendata.cz/resource/dataset/product-open-data.org/2014-01-01
>;
DB.DBA.TTLP ('
@prefix rr: <http://www.w3.org/ns/r2rml#> .
@prefix foaf: <http://xmlns.com/foaf/0.1/> .
@prefix gr: <http://purl.org/goodrelations/v1#> .
@prefix s: <http://schema.org/> .
@prefix pod: <http://linked.opendata.cz/ontology/product-open-data.org#>
<#TriplesMapBrand>
a rr:TriplesMap;
rr:logicalTable [
      rr:tableSchema "POD";
      rr:tableOwner  "DBA";
      rr:tableName   "BRAND"
];
    rr:subjectMap
    [
      rr:template "http://linked.opendata.cz/resource/brand/{BSIN}";;
      rr:class gr:Brand;
      rr:graph <
http://linked.opendata.cz/resource/dataset/product-open-data.org/2014-01-01>
    ];
   rr:predicateObjectMap [
        rr:predicateMap [rr:constant pod:bsin];
        rr:objectMap [rr:termType rr:Literal; rr:column "BSIN" ];
];
 rr:predicateObjectMap [
        rr:predicateMap [rr:constant gr:name];
        rr:objectMap [rr:termType rr:Literal; rr:column "BRAND_NM" ];
];
 rr:predicateObjectMap [
        rr:predicateMap [rr:constant s:url];
        rr:objectMap [rr:termtype "IRI"; rr:template "{BRAND_LINK}";];

];.
', 'http://product-open-data.org/temp', 'http://product-open-data.org/temp',
0);

exec ('sparql ' || DB.DBA.R2RML_MAKE_QM_FROM_G ('
http://product-open-data.org/temp','
http://linked.opendata.cz/resource/dataset/product-open-data.org/2014-01-01')
);


SPARQL Select * from <
http://linked.opendata.cz/resource/dataset/product-open-data.org/2014-01-01>
where {?s ?o ?p.} limit 1000000;


My problem is following I want to get TTL file with this procedure
<http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtRDFDatasetDump>
 .
But when I run this procedure like this in iSQL

SQL> DB.DBA.dump_one_graph('
http://linked.opendata.cz/resource/dataset/product-o
pen-data.org/2014-01-01','../R2RML/pod_',1000000000);

But only thing I get is this

# Dump of graph <
http://linked.opendata.cz/resource/dataset/product-open-data.org/2014-01-01>,
as of 2014-11-11 23:46:48.000004

So my question is where is my triples stored and why is SPARQL SELECT
returning result set while DUMP_ONE_GRAPH isnt?

Thank you.

Kind regards
