Btrieve ODBC Driver

The Pervasive SQL (Btrieve) ODBC Driver is a powerful tool that allows you to connect with Btrieve-based databases directly from any applications that support ODBC connectivity.

Access Btrieve databases from virtually anywhere through a standard ODBC Driver interface.



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

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

Connect to Btrieve 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.

The PSQL v13 client will need to be installed on the same machine as the driver. To connect, set the User, Password, Server, and Database properties.

Create a Profile for the ODBC Driver for Btrieve

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

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

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