Connect to Workday data in Ruby with ruby-dbi, dbd-odbc, and ruby-odbc.
The CData ODBC Driver for Workday makes it easy to integrate connectivity to live Workday data in Ruby. This article shows how to create a simple Ruby app that connects to Workday data, executes a query, and displays the results.
Create an ODBC Connection to Workday 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.
To connect, there are three pieces of information required: Authentication, API URL, and WSDL URL.
Authentication
To authenticate, specify your User and Password. Note that you must append your Tenant to your User separated by an '@' character. For instance, if you normally log in with 'geraldg' and your Tenant is 'mycompany_mc1', then your User should be specified as 'geraldg@mycompany_mc1'.
API URL
The API URL may be specified either directly via APIURL, or it may be constructed from the Tenant, Service, and Host. The APIURL is constructed in the following format: <Host>/ccx/service/<Tenant>/<Service>.
WSDL URL
The WSDLURL may be specified in its entirety, or may be constructed from the Service and WSDLVersion connection properties. The WSDLURL is constructed in the following format: https://community.workday.com/sites/default/files/file-hosting/productionapi/<Service>/<WSDLVersion>/<Service>.wsdl
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 Workday Data
Create a new Ruby file (for example: WorkdaySelect.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 Workday Source','','')
#execute a SELECT query and store the result set
resultSet = cnxn.execute("SELECT Worker_Reference_WID, Legal_Name_Last_Name FROM Workers WHERE Legal_Name_Last_Name = 'Morgan'")
#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 Workday data with Ruby. To do so, simply run your file from the command line:
ruby WorkdaySelect.rb
