#140 Virtuoso 37000 Error SQ156: Internal Optimized compiler erro

Bug (92)

I'm new to dbpedia/SPARQL, and I'm trying to query for programming languages based on rdfs:labels. When I issued this query, dbpedia borked:

Virtuoso 37000 Error SQ156: Internal Optimized compiler error : dt not found based on cname in sqlo.c:1081.
Please report the statement compiled.

SPARQL query:
define sql:big-data-const 0
define sql:signal-void-variables 1 define input:default-graph-uri <http://dbpedia.org> SELECT DISTINCT ?lang {
?lang rdf:type <http://dbpedia.org/ontology/ProgrammingLanguage> .
?lang rdf:labels ?labels .
FILTER(bif:contains(?labels, "D") || bif:contains(?labels, "D (programming language)"))
Limit 1000

As a side note, could someone help me with the proper syntax/query for searching dbpedia for programming languages by name?


  • Wonderful blog! I found it while surfing around on Yahoo News. Do you have any suggestions on how to get listed in Yahoo News? I've been trying for a while but I never seem to get there! Cheers
