Actually my requirement is I have developed webpage/report using Shiny package then I was deployed it on Shinyapps.io ,but after deploying I?m encountering error like ??ERROR: *first argument is not an open RODBC channel*? ,based on this error message I did searched in google and found that we need to use freeTDS drivers instead of RODBC but I found some articles regarding freeTDS but it?s not useful for me. I was eagerly waiting for solution from someone since last month, but not yet and this issue is not allowing me to further .Can anyone please help me out me(how to install freeTDS and how to configure it) on same.

Manu, Read the first paragraph under section "1 ODBC Concepts" of cran.r-project.org/web/packages/RODBC/vignettes/RODBC.pdf. This describes the relationship among the various parts of the technical stack that allows connectivity to the database system via ODBC. One of the points made is that RODBC uses an ODBC driver (e.g., Actual Technologies, Easysoft and OpenLink). I use the driver from Actual Technologies on Mac OS, but many others have used freeTDS. I had trouble with freeTDS years ago and decided my time was worth the minor cost of using the commercial product from Actual Technologies. The driver you use is computer OS specific while RODBC is not. It is also convenient to use an ODBC manager, which is typically a graphical application used to create and manage the configuration files used by the ODBC driver. Mark R.

[R] How to connect Microsoft Sql server from R studio using freeTDS instead of RODBC package
Hi Mark, Thank you so much for reply, using exiting ODBC drivers I will make a connection to sql server and it?s working fine in my local, but as per shinyapps.io I need to use freeTDS drivers instead RODBC ,so that I may not encounter the any issue .For me here challenging work is how to install freeTDS on my machine and how to configure it? Is there any drivers/way that can i make a connection to sql server and I shouldn?t encounter the issue after deploying application on shinyapps.io. Thanks,Manu.
