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).

Create a Data Access Object for Google Drive Data using JDBI

A brief overview of creating a SQL Object API for Google Drive data in JDBI.

JDBI is a SQL convenience library for Java that exposes two different style APIs, a fluent style and a SQL object style. The CData JDBC Driver for Google Drive integrates connectivity to live Google Drive data in Java applications. By pairing these technologies, you gain simple, programmatic access to Google Drive data. This article walks through building a basic Data Access Object (DAO) and the accompanying code to read and write Google Drive data.

Create a DAO for the Google Drive Files Entity

The interface below declares the desired behavior for the SQL object to create a single method for each SQL statement to be implemented.

public interface MyFilesDAO { //insert new data into Google Drive @SqlUpdate("INSERT INTO Files (Starred, Size) values (:starred, :size)") void insert(@Bind("starred") String starred, @Bind("size") String size); //request specific data from Google Drive (String type is used for simplicity) @SqlQuery("SELECT Size FROM Files WHERE Starred = :starred") String findSizeByStarred(@Bind("starred") String starred); /* * close with no args is used to close the connection */ void close(); }

Open a Connection to Google Drive

Collect the necessary connection properties and construct the appropriate JDBC URL for connecting to Google Drive.

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.

A connection string for Google Drive will typically look like the following:


Use the configured JDBC URL to obtain an instance of the DAO interface. The particular method shown below will open a handle bound to the instance, so the instance needs to be closed explicitly to release the handle and the bound JDBC connection.

DBI dbi = new DBI("jdbc:googledrive:InitiateOAuth=GETANDREFRESH"); MyFilesDAO dao =; //do stuff with the DAO dao.close();

Read Google Drive Data

With the connection open to Google Drive, simply call the previously defined method to retrieve data from the Files entity in Google Drive.

//disply the result of our 'find' method String size = dao.findSizeByStarred("true"); System.out.println(size);

Write Google Drive Data

It is also simple to write data to Google Drive, using the previously defined method.

//add a new entry to the Files entity dao.insert(newStarred, newSize);

Since the JDBI library is able to work with JDBC connections, you can easily produce a SQL Object API for Google Drive by integrating with the CData JDBC Driver for Google Drive. Download a free trial and work with live Google Drive data in custom Java applications today.
