HarperDB ODBC Driver

The HarperDB ODBC Driver is a powerful tool that allows you to connect with live data from HarperDB, directly from any applications that support ODBC connectivity.

Access HarperDB data like you would a relational database - read, write, and update HarperDB through a standard ODBC Driver interface.



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

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

Connect to HarperDB 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 Server, User, and Password connection properties to connect to HarperDB. Set UseSSL to secure connections with TLS/SSL.

Create a Profile for the ODBC Driver for HarperDB

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

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

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