Connect to SAP Business Warehouse Data from PowerBuilder via ODBC

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

Connect to SAP Business Warehouse 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 to SAP Business Warehouse, set the URL property to a valid SAP Business Warehouse server base URL. The driver must connect to SAP Business Warehouse instances hosted over HTTP with XMLA access.

The driver supports the following authentication schemes via the AuthScheme property:

• None: Anonymous authentication, if available on the server.
• Basic: Set User and Password and set AuthScheme to Basic.
• Kerberos: See the Using Kerberos section of the help documentation for the required Kerberos properties.

By default, the driver attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats.

Create a Profile for the ODBC Driver for SAP Business Warehouse

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

Using SAP Business Warehouse 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 SAP Business Warehouse data into a DataWindow. You can add the following code to the open method:

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