Connect to Spotify Data from PowerBuilder via JDBC

The CData JDBC driver for Spotify is a standards-based control that can be used from any platform or development technology that supports JDBC, including PowerBuilder. This article shows how to use the CData JDBC Driver for Spotify in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData JDBC Driver for Spotify to retrieve data.

Connect to Spotify Data from PowerBuilder

Follow the steps below to use the Database Painter tool to create a database profile based on an JDBC URL for Spotify. You can use a database profile to save connection properties. In the Database Painter, you can graphically manipulate data as well as execute SQL queries.

1. Add the driver JAR to the PowerBuilder classpath. Set the CLASSPATH system environment variable to the path to the driver JAR, located in the lib subfolder of the installation directory.

   Note: If you are using PowerBuilder Classic, you can also add the path to the driver JAR by clicking Tools -> System Options -> Java.

2. Click Tools -> Database Painter.
3. Right-click the JDBC node and click New Profile.
4. In the Database Profile Setup dialog, enter the following:
   • Profile Name: Enter a user-friendly name for the profile.
   • Driver Name: Enter the class name of the driver, cdata.jdbc.api.APIDriver
   • URL: Enter the JDBC URL.

     Using OAuth Authentication

     Spotify uses OAuth 2.0 for authentication. You will need to create an application in the Spotify Developer Dashboard to obtain your client credentials.

     Setting Up Your Spotify Application

     1. Visit the Spotify Developer Dashboard.
     2. Log in with your Spotify account and click Create app.
     3. Provide an app name, description, and set a Redirect URI (e.g.,

        http://localhost:33333

        for desktop applications).
     4. Copy your Client ID and Client Secret from the app settings.

     Connection Properties

     After setting the following connection properties, you are ready to connect:

     • AuthScheme: Set this to OAuth.
     • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
     • OAuthClientId: Set this to your Spotify application's Client ID.
     • OAuthClientSecret: Set this to your Spotify application's Client Secret.
     • Scope: Set this to the required OAuth scopes (space-separated). The default includes all read scopes needed for the tables in this profile.
     • CallbackURL: Set this to the Redirect URI configured in your Spotify application (e.g., http://localhost:33333).

     Example Connection String

     Profile=C:\profiles\Spotify.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackURL=http://localhost:33333;
     

     Available OAuth Scopes

     • user-read-private: Read access to user's subscription details and explicit content settings.
     • user-read-email: Read access to user's email address.
     • user-library-read: Read access to a user's saved tracks, albums, episodes, shows, and audiobooks.
     • playlist-read-private: Read access to user's private playlists.
     • playlist-read-collaborative: Read access to collaborative playlists the user follows.
     • user-follow-read: Read access to the list of artists the current user follows.
     • user-read-playback-state: Read access to a user's player state (device, current track, progress).
     • user-read-currently-playing: Read access to a user's currently playing content.
     • user-read-playback-history: Read access to a user's recently played tracks.
     • user-top-read: Read access to a user's top artists and tracks.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.api.jar
     

     Fill in the connection properties and copy the connection string to the clipboard. A typical JDBC URL is below:

     jdbc:api:Profile=C:\profiles\Spotify.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackURL=http://localhost:33333;

   
5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Spotify Data with PowerBuilder Controls

You can use standard PowerBuilder objects to connect to JDBC data sources and execute queries. The following example shows how to retrieve Spotify data into a DataWindow. You can add the following code to the open method:

SQLCA.DBMS = "JDBC"
SQLCA.AutoCommit = False
SQLCA.DBParm = "Driver='cdata.jdbc.api.APIDriver',URL='jdbc:api:Profile=C:\profiles\Spotify.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackURL=http://localhost:33333;";
CONNECT USING SQLCA;
dw_albums.SetTransObject(SQLCA);
dw_albums.Retrieve();
