What's causing 'unable to connect to data source' for pyodbc?

Question

I\'m trying to connect to an MSSQL database from python on Linux (SLES).

I have installed pyodbc and Free TDS. From the command line:

tsql -H server          


        

Answer 1

After hours of going in circles it turns out all I was missing was

TDS_Version = 8.0 in the DSN in my odbc.ini file.

I had specified it elsewhere, but it needed to be here, too, apparently.

Hope this helps some other poor soul.
