I am debugging a script I wrote to apply a construct query to our Virtuoso
version 06.01.3127 triple store. I am using the Jena framework to do so. The
error message is:
Exception in thread "main" com.hp.hpl.jena.shared.JenaException: Convert
results are FAILED.:virtuoso.jdbc3.VirtuosoException: Bad column number : 2 not
in 1<n<1
The example query on Construct queries
(http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtJenaSPARQLExample9)
returns the exact same error message:
SELECT results:
{ http://aa http://bb cc . }
{ http://aa1 http://bb 123^^http://www.w3.org/2001/XMLSchema#decimal . }
Exception in thread "main" com.hp.hpl.jena.shared.JenaException: Convert
results are FAILED.:virtuoso.jdbc3.VirtuosoException: Bad column number : 2 not
in 1<n<1

Any idea’s on how to fix this would be highly appreciated.
