FORM_FATAL in Oracle Forms

Returns the outcome of the action most recently performed during the current Run form session.

Use FORM_FATAL to test the outcome of a built–in to determine further processing within any trigger. To get the correct results, you must perform the test immediately after the action executes. That is, another action should not occur prior to the test.

Example:

/* ** Built–in: FORM_FATAL

** Example: Check whether the most–recently executed built–in  had a fatal error.*/

BEGIN

User_Exit(’Calculate_Line_Integral control.start control.stop’);

/*

** If the user exit code returned a fatal error, print a

** message and stop executing this trigger.

**

** Generally it is recommended to test **

** IF NOT FORM_SUCCESS THEN ... **

** Rather than explicitly testing for FORM_FATAL

IF Form_Fatal THEN

Message(’Cannot calculate the Line Integral due to internal error.’);

RAISE Form_Trigger_Failure;

END IF;
