Connect to Humanity Data from PowerBuilder via JDBC
The CData JDBC driver for Humanity 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 Humanity in PowerBuilder.
This article shows how to create a basic PowerBuilder application that uses the CData JDBC Driver for Humanity to retrieve data.
Connect to Humanity Data from PowerBuilder
Follow the steps below to use the Database Painter tool to create a database profile based on an JDBC URL for Humanity. 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.
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.
- Click Tools -> Database Painter.
- Right-click the JDBC node and click New Profile.
- 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.
Start by setting the Profile connection property to the location of the Humanity Profile on disk (e.g. C:\profiles\Humanity.apip). Next, set the ProfileSettings connection property to the connection string for Humanity (see below).
Humanity API Profile Settings
Create an OAuth application from Settings > API V2 in your Humanity account to obtain an App ID and App Secret.
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the Humanity 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\Humanity.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;
- To view and modify a table, right-click a table and then click Edit Data -> Grid.
Using Humanity 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 Humanity 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\Humanity.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;"; CONNECT USING SQLCA; dw_budget.SetTransObject(SQLCA); dw_budget.Retrieve();
