Hi Anton, Can you please provide an iODBC trace of your attempts to insert unicode data with the Virtuoso unicode driver (virtodbc32u_r.so) with the mxODBC and pyodbc drivers. The iODBC tracing can be enabled by adding the following entry to your odbc.ini file:
[ODBC] Trace=1 TraceFile=<filename> This will enable us to see where the Memory Allocation error is occuring during the attempt to insert the data and hopefully to diagnose the cause of the problem Regards, Hugh On 2/4/07 23:39, "Anton Krasovsky" <anton_krasov...@yahoo.com> wrote: > Hi Hugh, > > I tried to do some tests, and found that pyodbc when > used with virtodbc32u_r.so fails to execute any > queries with error: > > "[HY001] [iODBC][Driver Manager]Memory allocation > error (-1211581185)" > > though it works for non-unicode queries with > virtodbc32_r.so. > > The mxODBC seem to work with virtodbc32u_r.so (at > least for non-unicode queries) but it crashes when > compiled for python25. > > My intention would be to use pyodbc with Python 2.5, > so I'll try to have closer look at this, perhaps I'll > contact pyodbc maintainer. > > Regards, > Anton > > --- Hugh Williams <hwilli...@openlinksw.com> wrote: > >> Hi Anton, >> >> Can you please provide details on how you are >> attempting to save these >> unicode strings as RDF literals ? >> >> From on OpenLink point of view both iODBC and the >> Virtuoso ODBC driver >> support unicode, although note for the Virtuoso ODBC >> Driver you need to >> ensure you are using the virtodbc32u_r.so which is >> the Unicode variant of >> this driver. >> >> What I am not sure about is the unicode support >> available in mxODBC or >> pyodbc, thus do you know if either of these drivers >> support unicode ? >> >> >> Best Regards, >> Hugh Williams >> Professional Services >> OpenLink Software >> Web: http://www.openlinksw.com >> Universal Data Access & Data Integration Technology >> Providers >> >> On 2/4/07 11:24, "Anton Krasovsky" >> <anton_krasov...@yahoo.com> wrote: >> >>> Hi, >>> >>> yesterday I tried to do few simple tests saving >> python >>> unicode string as RDF literals in Virtuoso, but >> with >>> no success.
