Create a Data Access Object for YouTube Data using JDBI

A brief overview of creating a SQL Object API for YouTube 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 YouTube integrates connectivity to live YouTube data in Java applications. By pairing these technologies, you gain simple, programmatic access to YouTube data. This article walks through building a basic Data Access Object (DAO) and the accompanying code to read YouTube data.

Create a DAO for the YouTube Videos 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 MyVideosDAO { //request specific data from YouTube (String type is used for simplicity) @SqlQuery("SELECT ViewCount FROM Videos WHERE MyRating = :myRating") String findViewCountByMyRating(@Bind("myRating") String myRating); /* * close with no args is used to close the connection */ void close(); }

Open a Connection to YouTube

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

YouTube uses the OAuth authentication standard. To access Google APIs on behalf on individual users, you can use the embedded CData credentials or you can register your own OAuth app.

OAuth also enables you to use a service account to connect on behalf of users in a Google Apps domain. To authenticate with a service account, you will need to register an application to obtain the OAuth JWT values.

Built-in Connection String Designer

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

java -jar cdata.jdbc.youtube.jar

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

A connection string for YouTube will typically look like the following:

jdbc:youtube:InitiateOAuth=GETANDREFRESH

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:youtube:InitiateOAuth=GETANDREFRESH"); MyVideosDAO dao = dbi.open(MyVideosDAO.class); //do stuff with the DAO dao.close();

Read YouTube Data

With the connection open to YouTube, simply call the previously defined method to retrieve data from the Videos entity in YouTube.

//disply the result of our 'find' method String viewCount = dao.findViewCountByMyRating("like"); System.out.println(viewCount);

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