Access Oracle HCM Cloud data like you would a database - read, write, and update Oracle HCM Cloud 0, etc. through a standard ODBC Driver interface.

Connect to Oracle HCM Cloud data in Ruby with ruby-dbi, dbd-odbc, and ruby-odbc.

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

Create an ODBC Connection to Oracle HCM Cloud 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.

Using Basic Authentication

You must set the following to authenticate to Oracle HCM Cloud:

  • User: The user of your account.
  • Password: The password of 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 Oracle HCM Cloud Data

Create a new Ruby file (for example: OracleHCMSelect.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 OracleHCM Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT SiteId, SiteName FROM RecruitingCESites WHERE Language = 'English'") #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 Oracle HCM Cloud data with Ruby. To do so, simply run your file from the command line:
