Connect to Teradata Data from PowerBuilder via ODBC

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

Connect to Teradata 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 Teradata, provide authentication information and specify the database server name.

• User: Set this to the username of a Teradata user.
• Password: Set this to the password of the Teradata user.
• DataSource: Specify the Teradata server name, DBC Name, or TDPID.
• Port: Specify the port the server is running on.
• Database: Specify the database name. If not specified, the default database is used.

Create a Profile for the ODBC Driver for Teradata

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

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

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