Connect to HubDB Data from PowerBuilder via JDBC

The CData JDBC driver for HubDB 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 HubDB in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData JDBC Driver for HubDB to perform reads and writes.

Connect to HubDB Data from PowerBuilder

Follow the steps below to use the Database Painter tool to create a database profile based on an JDBC URL for HubDB. 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.hubdb.HubDBDriver
   • URL: Enter the JDBC URL.

     There are two authentication methods available for connecting to HubDB data source: OAuth Authentication with a public HubSpot application and authentication with a Private application token.

     Using a Custom OAuth App

     AuthScheme must be set to "OAuth" in all OAuth flows. Be sure to review the Help documentation for the required connection properties for you specific authentication needs (desktop applications, web applications, and headless machines).

     Follow the steps below to register an application and obtain the OAuth client credentials:

     1. Log into your HubSpot app developer account.
        • Note that it must be an app developer account. Standard HubSpot accounts cannot create public apps.
     2. On the developer account home page, click the Apps tab.
     3. Click Create app.
     4. On the App info tab, enter and optionally modify values that are displayed to users when they connect. These values include the public application name, application logo, and a description of the application.
     5. On the Auth tab, supply a callback URL in the "Redirect URLs" box.
        • If you're creating a desktop application, set this to a locally accessible URL like http://localhost:33333.
        • If you are creating a Web application, set this to a trusted URL where you want users to be redirected to when they authorize your application.
     6. Click Create App. HubSpot then generates the application, along with its associated credentials.
     7. On the Auth tab, note the Client ID and Client secret. You will use these later to configure the driver.

     8. Under Scopes, select any scopes you need for your application's intended functionality.

        A minimum of the following scopes is required to access tables:

        • hubdb
        • oauth
        • crm.objects.owners.read
     9. Click Save changes.
     10. Install the application into a production portal with access to the features that are required by the integration.
         • Under "Install URL (OAuth)", click Copy full URL to copy the installation URL for your application.
         • Navigate to the copied link in your browser. Select a standard account in which to install the application.
         • Click Connect app. You can close the resulting tab.

     Using a Private App

     To connect using a HubSpot private application token, set the AuthScheme property to "PrivateApp."

     You can generate a private application token by following the steps below:

     1. In your HubDB account, click the settings icon (the gear) in the main navigation bar.
     2. In the left sidebar menu, navigate to Integrations > Private Apps.
     3. Click Create private app.
     4. On the Basic Info tab, configure the details of your application (name, logo, and description).
     5. On the Scopes tab, select Read or Write for each scope you want your private application to be able to access.
     6. A minimum of hubdb and crm.objects.owners.read is required to access tables.
     7. After you are done configuring your application, click Create app in the top right.
     8. Review the info about your application's access token, click Continue creating, and then Show token.
     9. Click Copy to copy the private application token.

     To connect, set PrivateAppToken to the private application token you retrieved.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.hubdb.jar
     

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

     jdbc:hubdb:AuthScheme=OAuth;OAuthClientID=MyOAuthClientID;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH;

   👁 The JDBC data source defined in the Database Profile Setup dialog. (Salesforce is shown.)
   
5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using HubDB 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 HubDB 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.hubdb.HubDBDriver',URL='jdbc:hubdb:AuthScheme=OAuth;OAuthClientID=MyOAuthClientID;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH;";
CONNECT USING SQLCA;
dw_northwindproducts.SetTransObject(SQLCA);
dw_northwindproducts.Retrieve();
