How to install odbc package to Databricks cluster? - r

Question

I need to access an Azure SQL Database from an R notebook in Databricks. To do this I aimed to use the odbc package, which installed fine on my local instance of R.
I have tried to install the package to the cluster using Databricks' interface, which always fails. I have also tried the following code within a notebook:
install.packages("odbc")
which results in:
Installing package into ‘/databricks/spark/R/lib’

* csw: unixodbc_dev (Solaris)
* brew: unixodbc (Mac OSX)
To use a custom odbc set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

I have also tried installing from github:
library(devtools)
devtools::install_github("r-dbi/odbc")
Which gives a different error:

In addition: Warning messages:
1: In install.packages("odbc") :

2: In install.packages("odbc") :

Any idea why this package will not install on Databricks when it works fine locally and when all other packages I have tried install on Databricks work fine using the same syntax?

Answer 1

Best option to access a SQL Database is using the preinstalled JDBC connectivity (see the Documentation).
If you want to use ODBC this requires (as mentioned in one of the comments) unix odbc. Good practice to install multiple packages is using init-scripts. Following python code is for creating an init-script for pyodbc installation.
script = """
sudo apt-get -q -y install unixodbc unixodbc-dev
sudo apt-get -q -y install python3-dev
sudo pip install pyodbc
curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add -
sudo curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list > /etc/apt/sources.list.d/mssql-release.list
sudo apt-get update
sudo ACCEPT_EULA=Y apt-get -q -y install msodbcsql
"""
dbutils.fs.put("/databricks/init/pyodbc/pyodbc.sh", script, True)
Hope this helps.
