Trigger on logoff trouble

741904Mar 3 2010 — edited Mar 3 2010
Hi to all,

I'd like to try setting a trigger on logoff event. But when I logoff either from the terminal and from the APEX's web igu admin nothing's added into the target table.

Any clue?
Thank.
Claude
------------------------------------------
The trigger code:
===========
CREATE OR REPLACE TRIGGER TrigLog
BEFORE LOGOFF ON CLASIE.SCHEMA
BEGIN
INSERT INTO TTRIG VALUES('Test');
END;

the table:
======
create table ttrig (message VARCHAR2(100));

No errors showned when creating both db objets.

My system:

Oracle Database 10g Express Edition Release 10.2.0.1.0 - Product
PL/SQL Release 10.2.0.1.0 - Production
CORE 10.2.0.1.0 Production
TNS for Linux: Version 10.2.0.1.0 - Production
NLSRTL Version 10.2.0.1.0 - Production

It is working perfectly in my laptop.

Did you exit from your SQL prompt or How are you checking that?

Regards.

Are you connecting as CLASIE and then logging off.

What roles are granted to the user?
DBA role perhaps?

Martijn,

The DBA role does not prevent the trigger been fired. So I think this is not the cause of the issue...

Hi Lakmal,

Yes, you're right, thanks for pointing out, I was a bit too hasty with my reply.
I ran some tests (which I should have done in the first place before posting ).
SQL>  create table loginfo(msg varchar2(1000));

Table created.

SQL> create or replace trigger test
  2  before logoff on hoek.schema
  3  begin
  4  insert into loginfo values( user||' logged off @ '||to_char(sysdate, 'dd-mm-yyyy hh24:mi:ss'));
  5  end;
  6  /

Trigger created.

when I logoff either from the terminal and from the APEX's web igu admin
which terminal?

How is APEXs web gui disconnecting?

I assume no regular disconnect in either case is made so no insert into the target table has taken place.

But starting and ending a regular sql*plus session should verify that the trigger is indeed working as expected.

Hello,

With 'terminal' I meant pl*sql terminal.

In order to be sure I'm well disconnected I have made a new trigger but now on the event on 'logon'. It works fine:

CREATE OR REPLACE TRIGGER Trig7174
AFTER LOGON ON CLASIE.SCHEMA
CALL p7174

where p7174 is a procedure inserting a value into a table:

CREATE OR REPLACE PROCEDURE p7174 IS
BEGIN
INSERT INTO TEST1 VALUES('p7174');
END;

Then if I can logon I suppose it's only possible if I've been previously logoff.

So to be clear, I connect through pl*sql and I disconnect from it by the 'disconnect' command.

Thank for all suggestions.
Regards.
Claude
