Again it appears that this query is valid

SELECT ?range ?comment
FROM ns:hasNoMaximumOrMinimumAreaGuidance
This is the dataset description
Did you mean:
WHERE
{ GRAPH ns:hasNoMaximumOrMinimumAreaGuidance
{
?x ns:hasNoMaximumOrMinimumAreaGuidance ?range .
?x ns:hasNoMaximumOrMinimumAreaGuidance ?comment
FILTER regex (?comment, "^^xsd:string") }
}
}
FROM creates the thing to query, GRAPH accesses it.
Andy
WHERE
{ ?x ns:hasNoMaximumOrMinimumAreaGuidance ?range .
?x ns:hasNoMaximumOrMinimumAreaGuidance ?comment
FILTER regex (?comment, "^^xsd:string") }
But I get an Error 400: Query may not include a dataset description (FROM/FROM
NAMED)
Can someone please advise on how I can rearrange the query to obtain a three
column table of results
range | prefix:ns | comment
Thank you

Subject: Valid SPARQL query no results
Hi list,
Using Fuseki-0.2.0, I'm trying to run queries on some test data. I load in the
data with the following command
./fuseki-server --update --file myfile.owl /dataset
Part of my test data is as below
###
http://www.semanticweb.org/ontologies/2010/11/section6energydomestic2010.owl#hasNoMaximumOrMinimumAreaGuidance
section6energydomestic2010:hasNoMaximumOrMinimumAreaGuidance rdf:type
owl:FunctionalProperty ,
owl:ObjectProperty ;
rdfs:comment "Due to
the target method set by carbon dioxide emissions standard 6.1, there is no need for
guidance on minimum or maximum area for windows, doors, rooflights and roof windows in
new dwellings."^^xsd:string ;
rdfs:range
section6energydomestic2010:Door ,
section6energydomestic2010:Framing ,
section6energydomestic2010:Glazing ,
section6energydomestic2010:RoofWindow ,
section6energydomestic2010:Rooflight ,
section6energydomestic2010:Window ;
rdfs:domain [
rdf:type owl:Class ;
owl:intersectionOf ( section6energydomestic2010:BuildingElement
section6energydomestic2010:NewDwelling
)
] .
After confirming that the syntax in the following query is valid, from the
control panel I submit the query but I get a 404 error: not found...
PREFIX xsd:<http://www.w3.org/2001/XMLSchema#>

FILTER regex (?comment, "^^xsd:string") }
Can someone please help me with my query. I wish to retrieve something like the
following
range ?b
?comment
-----------------------------------------------------------------------------------------------------------------
Door hasNoMaximumOrMinimumAreaGuidance Due to the target method set
by carbon dioxide emissions standard 6.1... blah blah blah
Framing hasNoMaximumOrMinimumAreaGuidance Due to the target method set by
carbon dioxide emissions standard 6.1... blah blah blah
Glazing hasNoMaximumOrMinimumAreaGuidance Due to the target method set by
carbon dioxide emissions standard 6.1... blah blah blah
etc
etc
etc
Any help would be great. Thanks
