Hi Hugh,
sorry, my fault. I didn't recognize the Virtuoso ISQL tool and used a
ISQL tool which I installed myself. With the Virtuoso ISQL tool it
works fine.
One follow-up question on that. How do I remove a rule graph from a
rule set? Using your example I tried:
rdfs_rule_set ('http://localhost:8890/schema/property_rules1', 'http://
localhost:8890/schema/test', 1);
But the results remain the same, i.e. for your example query :
http://localhost:8890/dataspace/discussion/oWiki-test1Wiki
http://localhost:8890/dataspace/test2/weblog/test2tWeblog
http://localhost:8890/dataspace
Thanks,
- Mirko

Hi Mirko,
I am asking what is the command line tool you are using to run the
commands giving problems ? The reference to unixODBC in your error
message indicates to me you are not using the Virtuoso isql tool as
this does not use unixODBC. The Virtuoso isql tool will be in the
"bin" directory of the virtuoso installation directory along with
the virtuoso server binary. Please provide the complete command
line output of the when encountering these errors, include the
command being run to start whatever SQL client tool you are using.
You cannot execute these functions from the Virtuoso SPARQL endpoint
as they are not SPARQL command, they must be run from the Virtuoso
SQL interface, generally the isql tool provided with Virtuoso.

Hugh Williams

Hi Hugh,
I ran the query via the ssh shell, is that what you mean by SQL
client? I also tried it via the SPARQL webinterface (www.myhost.org:
8890/sparql).
The examples from the doc don't work either. I can't even load data
with ttlp. Here is what I get:
Query string:
ttlp( [ example from http://docs.openlinksw.com/virtuoso/rdfsparqlrule.html#rdfsparqlruleexamples
] );
Result in ISQL:

Hi Mirko,
What is this SQL client you are using that references unixODBC as
I presume it is not the Virtuoso isql client ? Have you tried
using the Virtuoso isql client to create the rule set as detailed
in the documentation at:
http://docs.openlinksw.com/virtuoso/rdfsparqlrule.html#rdfsparqlruleexamples

Hi,
I would like to make rule sets for inferencing. From ISQL I tried:
SQL> rdfs_rule_set ('defaultRules', 'http://arbitraryuri.org/
test/');
(where http://arbitraryuri.org/test/ is an existing local graph
that
contains some statements), which results in:
[37000][unixODBC][OpenLink][Virtuoso iODBC Driver][Virtuoso Server]
SQ074: Line 1: syntax error
[ISQL]ERROR: Could not SQLPrepare
Can you give me an idea what's going wrong here?
I use
Virtuoso: 05.11.3039, Build: Jun 1 2009
ISQL: unixODBC 2.2.11
Thanks,
