Phantom

Usage

Phantom fields are never displayed to the user, although they can be used by dialog instructions of BDL programs. If you want to implement a screen-array with all the columns of a database table defined in the schema file, but you don't want to display all the columns in the table, you must use Phantom fields. With the screen-array matching the database table, you can easily write program code to fetch all columns into an array defined with a LIKE clause.

Phantom fields can be based on database columns defined in a schema file or as NON_DATABASE field.

Phantom fields are used to store the id and parent id of the nodes in a tree object.

To add a Phantom field to your form, right-click on the form object and select Add Phantom from the context menu.

Phantom field data is never send to the front-ends. Therefore, you can use a phantom field to store critical data that must not go out of the application server.
