Connect to Azure Management Data in JRuby

Create a simple JRuby app with access to live Azure Management data.

JRuby is a high-performance, stable, fully threaded Java implementation of the Ruby programming language. The CData JDBC Driver for Azure Management makes it easy to integrate connectivity to live Azure Management data in JRuby. This article shows how to create a simple JRuby app that connects to Azure Management data, executes a query, and displays the results.

Configure a JDBC Connection to Azure Management Data

Before creating the app, note the installation location for the JAR file for the JDBC Driver (typically C:\Program Files\CData\CData JDBC Driver for Azure Management\lib).

JRuby natively supports JDBC, so you can easily connect to Azure Management and execute SQL queries. Initialize the JDBC connection with the getConnection function of the java.sql.DriverManager class.

Azure Data Management uses the OAuth 2 authentication standard. See the Getting Started section of the CData driver documentation for a guide.

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the Azure Management JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.azuredatamanagement.jar

Fill in the connection properties and copy the connection string to the clipboard.

Below is a typical JDBC connection string for Azure Management:

jdbc:azuredatamanagement:InitiateOAuth=GETANDREFRESH

Create a JRuby App with Connectivity to Azure Management Data

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

require 'java' require 'rubygems' require 'C:/Program Files/CData/CData JDBC Driver for Azure Management 2018/lib/cdata.jdbc.azuredatamanagement.jar' url = "jdbc:azuredatamanagement:InitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT DisplayName, AuthorizationSource FROM Subscriptions") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S AzureDataManagementSelect.rb

Writing SQL-92 queries to Azure Management allows you to quickly and easily incorporate Azure Management data into your own JRuby applications. Download a free trial today!
