Oracle Forms Developer – Form Builder Reference, Volume 1

On-Delete trigger
Description
Fires during the Post and Commit Transactions process and replaces the default Form Builder processing
for handling deleted records during transaction posting. Specifically, it fires after the Pre-Delete trigger
fires and before the Post-Delete trigger fires, replacing the actual database delete of a given row. The
trigger fires once for each row that is marked for deletion from the database.
Definition Level form or block
Legal Commands
SELECT statements, DML statements (DELETE, INSERT, UPDATE), unrestricted built-ins
Enter Query Mode no
Usage Notes
• Use an On-Delete trigger to replace the default Form Builder processing for handling deleted
records during transaction posting.
• To perform the default Form Builder processing from this trigger, that is, to delete a record from
your form or from the database, include a call to the DELETE_RECORD built-in.
On Failure
Form Builder rolls back to the most recent savepoint

On-Delete trigger examples
Example
This example updates the employee table to set the Termination_Date, rather than actually deleting the
employee from the database.
BEGIN
UPDATE emp
SET termination_date = SYSDATE
WHERE empno = :Emp.Empno;
IF form_fatal OR form_failure THEN
raise form_trigger_failure;
END IF;
END;
