Connect to Cloudant Data from PowerBuilder


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

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

Connect to Cloudant 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.

Set the following connection properties to connect to Cloudant:

  • User: Set this to your username.
  • Password: Set this to your password.

Create a Profile for the ODBC Driver for Cloudant

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

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

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