Connect to Streak Data in JRuby


Create a simple JRuby app with access to live Streak data.

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

Configure a JDBC Connection to Streak 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 Streak\lib).

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

Use the following steps to generate a new API key for authenticating to Streak.

  1. Navigate to Gmail
  2. Click on the Streak dropdown to the right of the search bar
  3. Select the Integrations button. This will open a window where you can view existing integrations and create new API keys.
  4. Under the Streak API section of integrations, click the button to Create New Key.

Built-in Connection String Designer

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

java -jar cdata.jdbc.streak.jar

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

Below is a typical JDBC connection string for Streak:

jdbc:streak:ApiKey=8c84j9b4j54762ce809ej6a782d776j3;

Create a JRuby App with Connectivity to Streak Data

Create a new Ruby file (for example: StreakSelect.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 Streak 2018/lib/cdata.jdbc.streak.jar' url = "jdbc:streak:ApiKey=8c84j9b4j54762ce809ej6a782d776j3;" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT UserKey, Email FROM Users") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S StreakSelect.rb

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