Hello @Moudma 

 

Open the ODBC application in Windows and click on any one of the DSN and further click on Advanced Options... to get the above window.

Hello @tusharkathpal 

I am using Rstudio web so do not need to configure ODBC on windows.

Hello @Moudma 

 

Rstudio is an application which I guess might be running on windows or mac OS. On these OS you will be downloading the ODBC application where you configure the DSN parameters. Under that configuration only, there is an Advanced Option where you will find the properties.
