Connect to Azure DevOps Data in JRuby


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

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

Configure a JDBC Connection to Azure DevOps 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 DevOps\lib).

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

You can connect to your Azure DevOps account by providing the Organization and PersonalAccessToken.

Obtaining a Personal Access Token

A PersonalAccessToken is necessary for account authentication.

To generate one, log in to your Azure DevOps Organization account and navigate to Profile -> Personal Access Tokens -> New Token. The generated token will be displayed.

If you wish to authenticate to Azure DevOps using OAuth refer to the online Help documentation for an authentication guide.

Built-in Connection String Designer

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

java -jar cdata.jdbc.azuredevops.jar

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

Below is a typical JDBC connection string for Azure DevOps:

jdbc:azuredevops:AuthScheme=Basic;Organization=MyAzureDevOpsOrganization;ProjectId=MyProjectId;PersonalAccessToken=MyPAT;InitiateOAuth=GETANDREFRESH

Create a JRuby App with Connectivity to Azure DevOps Data

Create a new Ruby file (for example: AzureDevOpsSelect.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 DevOps 2018/lib/cdata.jdbc.azuredevops.jar' url = "jdbc:azuredevops:AuthScheme=Basic;Organization=MyAzureDevOpsOrganization;ProjectId=MyProjectId;PersonalAccessToken=MyPAT;InitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT Id, BuildNumber FROM Builds") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S AzureDevOpsSelect.rb

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