Connect to IBM Cloud Data Engine Data in Ruby



Connect to IBM Cloud Data Engine data in Ruby with ruby-dbi, dbd-odbc, and ruby-odbc.

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

Create an ODBC Connection to IBM Cloud Data Engine 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.

IBM Cloud Data Engine uses the OAuth and HMAC authentication standards. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

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 IBM Cloud Data Engine Data

Create a new Ruby file (for example: IBMCloudDataEngineSelect.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 IBMCloudDataEngine Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT Id, Status FROM Jobs WHERE UserId = [email protected]") #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 IBM Cloud Data Engine data with Ruby. To do so, simply run your file from the command line:

ruby IBMCloudDataEngineSelect.rb Writing SQL-92 queries to IBM Cloud Data Engine allows you to quickly and easily incorporate IBM Cloud Data Engine data into your own Ruby applications. Download a free trial today!
