Connect to Couchbase Data from PowerBuilder

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

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

Connect to Couchbase 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 using the Login method, set User, Password, and Server to the credentials for the account and the address of the server you want to connect to.

Create a Profile for the ODBC Driver for Couchbase

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

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

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