Hi,
I would like to ask for a bit of advice on how to
get RDF type information for the SPARQL query result.
Normally results of SPARQL query over ODBC connection
are strings. I would like to find out their actual RDF
types (iri, literal, etc).
So far my approach was using output:format and par
Hi,
according to the docs it is possible to use
expressions
in SELECT clause. I'm trying to use some functions
like isIRI(), isLiteral() but it does not always work.
For example, while I can run this query:
sparql select (isiri(?o)) where {?s ?p ?o};
These queries fail:
sparql select (isiri
Thanks guys for your excellent support!

Anton

Hi,
I just noticed that when running SPARQL query with
output:format (TTL or RDF/XML it does not matter)
setting, immediately after the server restart, query
results are always returned in the valmode LONG
format.
Subsequent queries (if made on different connection)
are OK.
For example:
# /etc/i
Hi Patrick!
Thanks for your help, I've rebuild it according to
instructions and got it running fine.
The one more thing I had to do is to
comment out struct pgm_info program_info in
binsrc/maildrop/odbc_mail.c.

Hi,
I'm upgrading from Virtuoso 5.0.0 to 5.0.1, to use it
with Python + PyODBC + iODBC.
Unfortunately after the upgrade my Python application
fails to connect with the error message:

undefined symbol: program_info (0); [IM003

Shouldn't this be the result of the first query?

Hi Guys,
trying to use new inference feature, I've found
that it stops working after I call RDF_GLOBAL_RESET()
which I use for cleanup in few test scripts.
BTW, is there any examples for "SPARQL Inserts,
Updates, and Deletions"?

Hi Patrick,
versions are as follows:
OpenSUSE 10.2
Virtuoso 5.0
pyodbc 2.0.35 with your patch
iODBC 3.52.5 with your patch
Python 2.5
Also, I had to patch pyodbc/cursor.cpp line 575 and
611 changing SQLINTEGER to SQLLEN to build it with
iODBC.

Anton

thanks for your fixes, especially for doing extra work

I've applied the patches, and I can run my non-unicode

Hi,
yesterday I tried to do few simple tests saving python
unicode string as RDF literals in Virtuoso, but with
no success. So I wonder if there is any existing guide
on
setting system up for Unicode support?
What db driver should I use mxODBC or pyodbc?
What ODBC manager unixODBC or iODBC?
What
Thanks!
Tell us more about coming (after 5.0, is it?)
inference
support?

Hi,
is there any way to programmatically insert
triples containing bnodes into the store?
Something similar to DB.DBA.RDF_QUAD_URI(...)?

Hi Jeff,
have a look here:
http://docs.openlinksw.com/virtuoso/rdfapiandsql.html
Section: 14.2.2.1 Data Import
you should be able to import your data using command
line tool 'isql'.
BTW, I suspect there may be a bug related to RDF
import
(or maybe I did something wrong), I had better results

It would be very nice to see GNU Readline support
added to isql in the future releases of Virtuoso.
Current input line editing is not very convenient.

Hi,
Is there any examples using RDF_DELETE_TRIPLES?
I'm looking for API to add/remove individual triples
from store, so far I was able to add triples using
RDF_QUAD_URI/RDF_QUAD_URI_L but its a bit unclear how
to remove triples.

Hi guys!
I was playing with SPARQL and triple store
functionality
of virtuoso, and hit a problem using
RDF_DELETE_TRIPLES
function, calling it causes an error:
SR185: Undefined procedure isiri.
It looks like both RDF_INSERT_TRIPLES and
RDF_DELETE_TRIPLES use isiri() function when they
should be
