Connect to Veeva Data in Ruby

Connect to Veeva data in Ruby with ruby-dbi, dbd-odbc, and ruby-odbc.

The CData ODBC Driver for Veeva makes it easy to integrate connectivity to live Veeva data in Ruby. This article shows how to create a simple Ruby app that connects to Veeva data, executes a query, and displays the results.

Create an ODBC Connection to Veeva Data

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

You are ready to connect after specifying the following connection properties:

  • Url: The host you see in the URL after you login to your account. For example: https://my-veeva-domain.veevavault.com
  • User: The username you use to login to your account.
  • Password: The password you use to login to your account.

Installing Ruby and Necessary Gems

If you do not have Ruby installed, refer to the Ruby installation page. With Ruby installed, you will need to install the ruby-dbi, dbd-odbc, and ruby-odbc gems:

gem install dbi gem install dbd-odbc gem install ruby-odbc

Create a Ruby App with Connectivity to Veeva Data

Create a new Ruby file (for example: VeevaSelect.rb) and open it in a text editor. Copy the following code into your file:

#connect to the DSN require 'DBI' cnxn = DBI.connect('DBI:ODBC:CData Veeva Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT ProductId, ProductName FROM NorthwindProducts WHERE CategoryId = 5") #display the names of the columns resultSet.column_names.each do |name| print name, "\t" end puts #display the results while row = resultSet.fetch do (0..resultSet.column_names.size - 1).each do |n| print row[n], "\t" end puts end resultSet.finish #close the connection cnxn.disconnect if cnxn

With the file completed, you are ready to display your Veeva data with Ruby. To do so, simply run your file from the command line:

ruby VeevaSelect.rb Writing SQL-92 queries to Veeva allows you to quickly and easily incorporate Veeva data into your own Ruby applications. Download a free trial today!
