Sorry, yes, I should have said I'm using pyodbc. I tried using iODBC, but I couldn't get iodbctest to recognise my DSNs, so I used unixodbc as it 'just worked'. I'll give it another go, and I might try setting up a second VM running Linux to run my tests off. I've had no problems with linux and unixodbc.
