Connect to Google Campaign Manager Data in JRuby

Create a simple JRuby app with access to live Google Campaign Manager data.

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

Configure a JDBC Connection to Google Campaign Manager 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 Google Campaign Manager\lib).

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

Google Campaign Manager uses the OAuth authentication standard. The data provider facilitates OAuth in various ways as described below. The following OAuth flow requires the authenticating user to interact with DoubleClick Campaign Manager, using the browser. You can also use a service account to authenticate.

For authentication guides, see the Getting Started section of the data provider help documentation.

Built-in Connection String Designer

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

java -jar cdata.jdbc.googlecm.jar

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

Below is a typical JDBC connection string for Google Campaign Manager:

jdbc:googlecm:UserProfileID=MyUserProfileID;InitiateOAuth=GETANDREFRESH

Create a JRuby App with Connectivity to Google Campaign Manager Data

Create a new Ruby file (for example: GoogleCMSelect.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 Google Campaign Manager 2018/lib/cdata.jdbc.googlecm.jar' url = "jdbc:googlecm:UserProfileID=MyUserProfileID;InitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT Clicks, Device FROM CampaignPerformance") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S GoogleCMSelect.rb
