Re: [Virtuoso-users] Connection is busy with results for another hstmt.

Thanks Hugh, but I'm not on OSX, but on Linux Ubuntu, and in the drivers provide for Linux (as you can see there : http://wikis.openlinksw.com/dataspace/owiki/wiki/UdaWikiWeb/InstallPostgreSQLLiteUnix There is no option for MASE in the process.

Re: [Virtuoso-users] Connection is busy with results for another hstmt.

Hi Julien, Please enable the Multiiple Active Statement Emulation (MASE) option of the UDA Postgres Lite Driver which should resolve this error as detailed at: http://wikis.openlinksw.com/dataspace/owiki/wiki/UdaWikiWeb/InstallPostgreSQLLiteOSX Best Regards Hugh Williams Professional

Re: [Virtuoso-users] Privileges problems

Hi Julien, What is the query you are executing and via what interface are you executing it ? Perhaps you also need to add the grant on the table the view is created from also, if not already done ? Please use the “trace_on()” function (http://docs.openlinksw.com/virtuoso/fn_trace_on.html) to e

[Virtuoso-users] Connection is busy with results for another hstmt.

Problem solved, but now I have another problem, when I execute my request now I have this error message : Virtuoso IM921 Error VD052: Remote DSN PostgreSQL Sample DSN: [OpenLink][ODBC][Driver]Connection is busy with results for another hstmt. Any idea of what's happened ? ---

[Virtuoso-users] Privileges problems

Hi, I made a R2RML mapping and I use a SQL view in this mapping that I created. So when I try to query the result of this mapping I fall on this error : Virtuoso 42000 Error SQ200: Must have select privileges on view musicbrainz_db.musicbrainz.musicbrainz_view Even if I do : GRANT SELECT ON mus

Re: [Virtuoso-users] MD5 function

Hi Lorena, Could you send us the output of: virtuoso-t -? It seems you are having Virtuoso version that does not support the SPARQL 1.1 function extensions. What about if you try with bif:MD5 ? So for ex: SELECT bif:MD5 ('test') WHERE { ?s ?p ?o } LIMIT 10 Best Regards, Rumi - Ori

Re: [Virtuoso-users] MD5 function

hi, check out this [1] post here, might not be implemented. there are also no samples working with bind on dbpedia endpoint and virtuoso's sparql grammar [2] doesn't mention bind as well. wkr turnguard [1] http://boards.openlinksw.com/phpBB3/viewtopic.php?f=12&t=2670 [2] http://docs.openlinksw.c

Re: [Virtuoso-users] OWL loading with DB.DBA.TTLP_MT it´s getting Error 37000

Hi Gabriel, The owl files are in RDF/XML format, so you need to use the Virtuoso DB.DBA.RDF_LOAD_RDFXML_MT() function for these are detailed at: http://www.openlinksw.com/dataspace/dav/wiki/Main/VirtRDFInsert#Loading%20RDF%20datasets%20into%20a%20Virtuoso%20Graph%20IRI Best Regards Hug
