Connect to GraphQL Data from PowerBuilder


This article demonstrates how to use the CData ODBC Driver for GraphQL to connect to GraphQL data and execute queries in PowerBuilder.

The CData ODBC Driver for GraphQL can be used from any platform or development technology that supports ODBC, including PowerBuilder. This article shows how to connect to GraphQL data and execute queries from the Database Painter and controls such as the DataWindow.

Connect to GraphQL as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

You must specify the URL of the GraphQL service. The driver supports two types of authentication:

  • Basic: Set AuthScheme to Basic. You must specify the User and Password of the GraphQL service.
  • OAuth 1.0 & 2.0: Take a look at the OAuth section in the Help documentation for detailed instructions.

Create a Profile for the ODBC Driver for GraphQL

Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for GraphQL. In the Database Painter, you can use wizards and the UI to work with GraphQL data.

  1. In PowerBuilder, click Tools -> Database Painter.
  2. In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
  3. On the Connection tab, enter a name for the profile and select the GraphQL DSN in the Data Source menu.
  4. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using GraphQL Data with PowerBuilder Controls

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

SQLCA.DBMS = "ODBC" SQLCA.DBParm = "ConnectString='DSN=CData GraphQL Source'" CONNECT USING SQLCA; dw_users.SetTransObject(SQLCA); dw_users.Retrieve();
