Google Drive Icon Google Drive JDBC Driver

An easy-to-use database-like interface for Java based applications and reporting tools access to live Google Drive data (Files, Changes, Apps, and more).

Connect to Google Drive Data in JRuby

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

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

Configure a JDBC Connection to Google Drive 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 Drive\lib).

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

You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.

Built-in Connection String Designer

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

java -jar cdata.jdbc.googledrive.jar

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

Below is a typical JDBC connection string for Google Drive:


Create a JRuby App with Connectivity to Google Drive Data

Create a new Ruby file (for example: GoogleDriveSelect.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 Drive 2018/lib/cdata.jdbc.googledrive.jar' url = "jdbc:googledrive:InitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT Name, Size FROM Files") while ( do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S GoogleDriveSelect.rb
