Connect to HPCC Systems Data from PowerBuilder

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

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

Connect to HPCC Systems 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.

To connect, set the following connection properties: Set URL to the machine name or IP address of the server and the port the server is running on, for example, https://server:port. The User and Password are required to authenticate to the HPCC Systems cluster specified in the URL. Note that LDAP authentication is not currently supported by our ODBC driver.

Set Version to the WsSQL Web server version. Note that if you have not already done so, you will need to install the WsSQL service on the HPCC Systems server. The WsSQL Web service is used to interact with the underlying HPCC Systems platform.

Set Cluster to the target cluster.

Create a Profile for the ODBC Driver for HPCC Systems

Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for HPCC Systems. In the Database Painter, you can use wizards and the UI to work with HPCC Systems 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 HPCC Systems DSN in the Data Source menu.
  4. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using HPCC Systems 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 HPCC Systems data into a DataWindow. You can add the following code to the open method:

SQLCA.DBMS = "ODBC" SQLCA.DBParm = "ConnectString='DSN=CData HPCC Source'" CONNECT USING SQLCA; dw_hpcc::test::orders.SetTransObject(SQLCA); dw_hpcc::test::orders.Retrieve();
