Hi,
I think I found a little bug in the SPARQL parser for Jena 2.12.0. When I
run the query :
SELECT count(distinct ?s) as ?count WHERE {?s ?p ?o}
Against the DBpedia SPARQL endpoint I have a result, but if I go through
Jena I have this error :
Exception in thread "main" com.hp.hpl.jena.query.QueryParseException:
Encountered " "count" "count "" at line 1, column 8.
Was expecting one of:
<VAR1> ...
<VAR2> ...
"distinct" ...
"reduced" ...
"(" ...
"*" ...

Is-this as I think a bug or I missed something in my query ?
Thanks in advance.
Best
