Connect to Strava Data from PowerBuilder via JDBC

The CData JDBC driver for Strava 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 Strava in PowerBuilder.

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

Connect to Strava Data from PowerBuilder

Follow the steps below to use the Database Painter tool to create a database profile based on an JDBC URL for Strava. 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.

     To authenticate to Strava, and connect to your own data or to allow other users to connect to their data, you can use the OAuth standard.

     Using OAuth Authentication

     You must create a custom OAuth application to connect to Strava. To create a custom OAuth application:

     1. Log into the Strava API Settings page
     2. Create a new application or select an existing application
     3. Set the "Authorization Callback Domain" to your callback URL domain (e.g. localhost)
     4. Note down the Client ID and Client Secret

     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 the Client ID from your Strava API application.
     • OAuthClientSecret: Set this to the Client Secret from your Strava API application.
     • CallbackURL: Set this to the redirect URI matching your application's callback domain.

     Example connection string:

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

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the Strava 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\Strava.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 Strava 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 Strava 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\Strava.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackURL=http://localhost:33333;";
CONNECT USING SQLCA;
dw_athlete.SetTransObject(SQLCA);
dw_athlete.Retrieve();
