Connect to Oracle Service Cloud Data in Ruby

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

Create an ODBC Connection to Oracle Service 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 Service Cloud:

• Url: The Url of the account to connect to.
• User: The username of the authenticating account.
• Password: The password of the authenticating 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 Service Cloud Data

Create a new Ruby file (for example: OracleServiceCloudSelect.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 OracleServiceCloud Source','','')

#execute a SELECT query and store the result set
resultSet = cnxn.execute("SELECT Id, LookupName FROM Accounts WHERE DisplayOrder = 12")

#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 Service Cloud data with Ruby. To do so, simply run your file from the command line:

ruby OracleServiceCloudSelect.rb
