Connect to Outlook Data from PowerBuilder via JDBC

The CData JDBC driver for Outlook 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 Outlook in PowerBuilder.

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

Connect to Outlook Data from PowerBuilder

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

     Microsoft Graph API uses OAuth 2.0 for authentication. You must register an application in the Microsoft Azure Portal to obtain OAuth credentials (Client ID and Client Secret).

     Obtaining OAuth Credentials

     1. Log in to the Azure Portal.
     2. Navigate to Azure Active Directory > App registrations.
     3. Click New registration to create a new application.
     4. Enter an application name and select the appropriate account types.
     5. Set the Redirect URI to your application's callback URL (e.g., http://localhost:33333 for desktop apps).
     6. Click Register to create the application.
     7. On the application overview page, copy the Application (client) ID - this is your OAuthClientId.
     8. Navigate to Certificates & secrets and create a new client secret.
     9. Copy the client secret value - this is your OAuthClientSecret.
     10. Navigate to API permissions and add the required Microsoft Graph API permissions:
         • Mail.Read - For accessing email messages
         • Contacts.Read - For accessing contacts
         • Calendars.Read - For accessing calendar events
         • Tasks.Read - For accessing To Do tasks
         • offline_access - For obtaining refresh tokens
     11. Click Grant admin consent to grant these permissions.

     Connecting with OAuth

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

     • AuthScheme: Set this to OAuth.
     • InitiateOAuth: Set this to GETANDREFRESH. The CData API Profile for Outlook will automatically walk through the OAuth process in order to obtain the access token.
     • OAuthClientId: Set this to the Application (client) ID from Azure Portal.
     • OAuthClientSecret: Set this to the client secret value from Azure Portal.
     • TenantId: Set this to your Azure AD tenant identifier (GUID or domain name like 'contoso.onmicrosoft.com').
     • CallbackURL: Set this to the Redirect URI you specified in your app registration (e.g., http://localhost:33333 for desktop apps).

     Example connection string

     Profile=C:\profiles\Outlook.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;TenantId=your_tenant_id;CallbackUrl=http://localhost:33333;
     

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the Outlook 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\Outlook.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;TenantId=your_tenant_id;CallbackUrl=http://localhost:33333;

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

Using Outlook 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 Outlook 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\Outlook.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;TenantId=your_tenant_id;CallbackUrl=http://localhost:33333;";
CONNECT USING SQLCA;
dw_calendargroupcalendars.SetTransObject(SQLCA);
dw_calendargroupcalendars.Retrieve();
