To access a database in a PowerBuilder application, you must specify the required connection parameters as properties of the Transaction object (SQLCA by default) in the appropriate script. For example, you might specify the connection parameters in the script that opens the application.
In PowerBuilder, the Preview tab in the Database Profile Setup dialog box makes it easy to generate accurate PowerScript connection syntax in the development environment for use in your PowerBuilder application script.
For instructions on using the Preview tab to help you connect in a PowerBuilder application, see the section on using Transaction objects in Application Techniques.
