Hi Dhaval,
You indicate the error occurs when running complex queries can you
provide an example of such queries in comparison with those that work.
If you could provide a sample program we could compile in house to
recreate the issue that would be even better. It might also be useful
to set trace_on() to enable more detailed trace on the server
(virtuoso.log) so we can see what queries and an errors that might be
occurring server side when the problem occurs Details on setting
trace_on are available at:

Hi Hugh,
I have tried with the latest jdbc driver from the link you had sent.
Still the same error:
com.hp.hpl.jena.shared.JenaException: Convert results are
FAILED.:virtuoso.jdbc3.VirtuosoException: Bad column number : 2 not
in 1<n<1
at virtuoso.jena.driver.VirtuosoQueryExecution.execConstruct

Hi Dhaval,
What is the version number of the Virtuoso JDBC Driver being used
( java virtuoso.jdbc3.Driver) ? Can you please re-try with the
latest cut available from:
ftp://download.openlinksw.com/support/vos/virtjdbc3.jar

Hi,
I have a program to run the construct queries from API ( snippet
below). For complex queries, while executed it complains with the
following:
Convert results are FAILED.:virtuoso.jdbc3.VirtuosoException: Bad
column number : 2 not in 1<n<1
It is occuring at line no 4 of the following..
1. VirtGraph set = new VirtGraph (url, "dba", "dba");
2. VirtuosoQueryExecution vqe = VirtuosoQueryExecutionFactory.create
(sparql, set);
3. vqe = VirtuosoQueryExecutionFactory.create (sparql, set);
4. Model model = vqe.execConstruct();
I am assuming that the result of the construct query execution
generates certain type of data that is creating problem...anybody
had similar problem/error?
thanks
Dhaval
