Description
Fires just before Oracle Forms 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:
- If Oracle Forms is entering the form for the first time and the trigger
fails, the form is exited gracefully, but no other triggers are fired.
- If the trigger fails while Oracle Forms is attempting to execute the
LOGON Built-in from within the trigger,
Oracle Forms raises the FORM_TRIGGER_FAILURE
exception.
