It’s read only. Thought it’d be obvious you can’t do updates? There’s so much business/system logic sitting in front of that data, allowing updates would be madness. Any 3rd party offerings that provide update operations may present themselves as ODBC, but they actually go through a NetSuite API (so RESTlet/Suitelet/SOAP/etc) to do updates, and won’t be very fast as a result. You’re better off looking at why you want to update & use mass updates or map/reduce scripts instead
