Pre-Logon trigger

Pre-Logon trigger


Fires just before Form Builder initiates a logon procedure to the data source.
Definition Level form

Legal Commands

SELECT statements, unrestricted built-ins
Enter Query Mode no

Usage Notes

Use a Pre-Logon trigger to prepare the form for the logon procedure, particularly to a non-ORACLE data source.

On Failure

The results of a failure depend on which of the following conditions applies:

n If Form Builder is entering the form for the first time and the trigger fails, the form is exited gracefully, but no other triggers are fired.

n If the trigger fails while Form Builder is attempting to execute the LOGON built-in from within the trigger, Form Builder raises the FORM_TRIGGER_FAILURE exception.
