(was: Thanks, [~dglachs]. Definetelly that looks like a bug in the visitor that builds the sql query. In principle the [patch|https://github.com/apache/marmotta/commit/56bcb6d299f6ec232f0b0fe82ef93697f91e4f0b|] look fine. But if you can also post here the query and some sample data, that would help to debug the issue.)

> SELECT DISTINCT ?uri ?title ?children {
>   GRAPH <http://host/context/graph> {
>     ?uri a <http://www.w3.org/2004/02/skos/core#ConceptScheme> .

> when using {{sparql.strategy=memory}} the query works!
