Creating a Field Trigger
Follow these steps to create a field trigger for an existing field:
- Choose Schema
Field Editor. Progress alphabetically lists all the tables defined for your database.
- Select the table that contains the field for which you want to create the trigger. The Field Editor window appears.
- Choose the Triggers option at the bottom of the window.
- Select the field for which you want to define the trigger. The Field Triggers dialog box appears:
![]()
- Specify the name of the trigger procedure, then press PUT to enter the trigger code. The Trigger Editor appears.
- Specify whether a session trigger can override the schema trigger. For more information about session and schema triggers, see the chapter on database triggers in the Progress Programming Handbook.
- Specify whether Progress verifies the cyclical redundancy check (CRC) code.
- Choose OK to create the trigger and return to the Field Editor.
