Connecting RStudio Connect with snowflake

Hi, i am trying to connect a snowflake database with a shiny application on rconnect.
But, i am getting error regarding odbc package.

Hi @akash_gangrade1, welcome to RStudio Community!
To help others have the best opportunity to help you, it's best to provide a reproducible example. The reprex R package can help create such an example.

In this case, it would be helpful to know the code you're using to try and connect to the database along with the specific error message you are receiving.

Hi Blair,

Thanks for the reply, are there any examples where rconnect can connect to snowflake.

I'm sure examples exist, although I don't have any handy. It would be helpful to see what you've already tried and what the specific error is.

It seems the snowflake website has some examples, for example at:

Thanks for the reply Andrie,
I am able to connect snowflake via r studio. But when i deploy the application to R connect it throws error regarding odbc package.

Thanks for posting the additional detail and error message.

It seems that you have not installed the necessary ODBC drivers on your Connect machine. To fix this situation, you will need to:

  • install the Snowflake ODBC drivers
  • define the necessary ODBC connection strings or DSNs.

RStudio does not provide an ODBC driver for Snowflake, so you will have to obtain the driver files elsewhere.

However, the installation process will most likely be similar to the instructions at https://docs.rstudio.com/pro-drivers/

You'll also need to make sure unixODBC is installed: https://github.com/r-dbi/odbc#linux---debian-ubuntu

HI,

I tried to install ODBC package on the connect server, but it failed everytime. Do i have to anything different to install it on connect server. It founds the package, unpacks it and throws error.

Hi,

I am the admin of R connect and some different team in the organization manages the server and installed R on the r connect server. Can i install drivers on the server myself or, i have to ask someone from the server team to do it.

You will probably need to ssh into the server and use sudo permissions to complete this installation. I suggest you speak to your server administration team, show them the Connect admin guide and ask for their support.
