Connect to PostgreSQL Data from PowerBuilder



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

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

Connect to PostgreSQL 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 PostgreSQL, set the Server, Port (the default port is 5432), and Database connection properties and set the User and Password you wish to use to authenticate to the server. If the Database property is not specified, the data provider connects to the user's default database.

Create a Profile for the ODBC Driver for PostgreSQL

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

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

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