When you say it does not work, what do you mean? You get no results, or you get an error? Your column_name in the where clause should be a predicate. For example, rdfs:subClassOf

I can execute this command using QueryFactory: SELECT ?x ?y ?z WHERE {?x ?y ?z } but if I want to specify the predicate SELECT ?x ?y ?z WHERE {?x column_name ?z } it does not work. Does the predicate and/or subject require a prefix? If I specify a prefix I don't get an error, but I will have to change all my data so that the query will work. Is this even a correct query?
