SQL Server 2014 RODBC Connection

Question

Does anyone have a connection string example for using RODBC and connecting to MS SQL Server 2014.

If I use below connection string works fine for SQL Server 2008 but not for 2014

library(RODBC)  

connectionstring <- odbcDriverConnect('driver={SQL Server};server=Serveraname\\Instance name,PortNumber;database=database name;uid=username;pwd=password;')

Answer 1

Is it the Instance name ? On SQL server 2014 you do not need an instance name AFAIK. I suggest you use the Native Client driver. It usually works fine with 2014 SQL servers.
