There is no default DSN. The application will take the name given in the 4GL database statement as an ODBC connect string. For instance: DATABASE ‘cms’
The application will search for a DSN named ‘cms’, e.g. DSN=cms.
Make sure that you have set ODBC_DSN environment variable correctly and there aren’t any names in the registry except HKLM\Software\Querix\Q4GL
