R help - Aug 2016 - How to connect Microsoft Sql server from R studio using freeTDS instead of RODBC package

Hi,



   Can anyone guide me how to connect the Microsoft Sql server 2012/14 from
R studio using freeTDS package instead of RODBC ,I can able to connect the
MS Sql server from R studio using RODBC.

  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.



My environment details :



    Os : windows 8

    R version 3.3.1 (2016-06-21)



Thanks in Advance .

Manu.

Manu,

Read the first paragraph under section "1 ODBC Concepts" of
https://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.

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.
