Run Process before Logout problem

Question

Good Afternoon,
I have two pages that I am trying to run a process before logging out of the system. The code works sometimes on page 4, and not at all on page 8. I have delete process on linked to the logout button.
code below.
PROC_DEL_LOGOUT
begin
delete from email_atch upper(userid) = upper(':APP_USER');
commt;
end;
button code
button with URL Redirect
javascript: doSubmit('LOGOUT'); redirect('&LOGOUT_URL.');I have similar code for when the browser closes, except in that javascript I just have it doing a doSubmit() to delete the files. Same problem, works sometimes on page 4, but not on page 8.
Can you attach validations to logout buttons or closing the browser's window?
Thanks,
Mary

Answer 1

I think this is the best way to do that
01. Create a procedure and then add your delete commands to it and logout process as below
CREATE OR REPLACE PROCEDURE MyLogout                        
AS
BEGIN
  delete from email_atch upper(userid) = upper(':APP_USER');
  COMMIT;
  wwv_flow_custom_auth_std.logout(p_this_flow=>your application id ,p_next_flow_page_sess=>Your target page after logout);     
END;* Please see the document for "wwv_flow_custom_auth_std.logout" for further information about this function and parameters
02. Grant permissions to apex_public_user
GRANT EXECUTE ON MyLogout to APEX_PUBLIC_USER;03. Change the logout url of Authentication schema as below
#OWNER#.MyLogout* This will amke sure to execute your code whenever application try to logout
