Re: [Dbpedia-discussion] Virtuoso 22023 Error SR008

[Patrick van Kleef]

Hi Konrad,

I was querying DBpedia, when I started to receive HTTP 500 errors, the
response says:

Virtuoso 22023 Error SR008: Function id_to_iri needs an IRI_ID or NULL
as argument 1, not an arg of type INTEGER (189) SPARQL query


to the example queries as well:

Example 1

http://dbpedia.org/snorql/?query=PREFIX+dbo%3A+%3Chttp%3A%2F%2Fdbpedia.org%2Fontology%2F%3E%0D%0A%0D%0ASELECT+%3Fname+%3Fbirth+%3Fdeath+%3Fperson+WHERE+%7B%0D%0A+++++%3Fperson+dbo%3AbirthPlace+%3ABerlin+.%0D%0A+++++%3Fperson+dbo%3AbirthDate+%3Fbirth+.%0D%0A+++++%3Fperson+foaf%3Aname+%3Fname+.%0D%0A+++++%3Fperson+dbo%3AdeathDate+%3Fdeath+.%0D%0A+++++FILTER+%28%3Fbirth+%3C+%221900-01-01%22%5E%5Exsd%3Adate%29+.%0D%0A%7D%0D%0AORDER+BY+%3Fname

Example 2

http://dbpedia.org/snorql/?query=SELECT+%3Fname+%3Fdescription_en+%3Fdescription_de+%3Fmusician+WHERE+%7B%0D%0A+++++%3Fmusician+%3Chttp%3A%2F%2Fpurl.org%2Fdc%2Fterms%2Fsubject%3E+%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2FCategory%3AGerman_musicians%3E+.%0D%0A+++++%3Fmusician+foaf%3Aname+%3Fname+.%0D%0A+++++OPTIONAL+%7B%0D%0A+++++++++%3Fmusician+rdfs%3Acomment+%3Fdescription_en+.%0D%0A+++++++++FILTER+%28LANG%28%3Fdescription_en%29+%3D+%27en%27%29+.%0D%0A+++++%7D%0D%0A+++++OPTIONAL+%7B%0D%0A+++++++++%3Fmusician+rdfs%3Acomment+%3Fdescription_de+.%0D%0A+++++++++FILTER+%28LANG%28%3Fdescription_de%29+%3D+%27de%27%29+.%0D%0A+++++%7D%0D%0A+++%7D

Is this a temporally server error?

First I thought my query became broken, but I noticed I get the response

Yes, it looks like on of the nodes did not properly initialize.

I restarted  the node and checked your samples which now all work again.
