SELECT { GRAPH xx { ... } } gives an error
With commit 1d8cf637 of 'master', I see the following problem:
$ tracker sparql -q 'SELECT ?u { GRAPH <urn:uuid:472ed0cc-40ff-4e37-9c0c-062d78656540> { ?u a nfo:FileDataObject } }'
Could not run query, no such column: rdfs:Resource_rdf:type1.rdf:type:graph
I'm not sure if this SELECT { GRAPH {
syntax is actually standard SPARQL 1.1, but it's something we document as working (in docs/reference/libtracker-sparql/migrating-2to3.xml for example).
The same query using FROM syntax doesn't give an error:
$ .tracker sparql -q 'SELECT ?u FROM <urn:uuid:472ed0cc-40ff-4e37-9c0c-062d78656540> { ?u a nfo:FileDataObject }'
Results:
None
