SELECT SESSIONTIMEZONE FROM DUAL;

Question

Hi,
On 10g , I have :
SELECT SESSIONTIMEZONE FROM DUAL;
SESSIONTIMEZONE                                                            
+01:00                                                                     
1 rows selectedWhich parameter should I change im my session to have :
SESSIONTIMEZONE                                                            
Europe/Paris
1 rows selectedIn documentation it is said :
SESSIONTIMEZONE returns the time zone of the current session. The return type is a time zone offset (a character type in the format '[+|]TZH:TZM') or a time zone region name, depending on how the user specified the session time zone value in the most recent ALTER SESSION statement.
Thank you.

Answer 1

I want to know in which time zone my session is ? Just to know its name but not the offset which is a number. Just to have something like :
select sessiontimezone, current_date from dual;
SESSIONTIMEZONE                                                             CURRENT_DATE             
Europe/Paris                                                                10-JANV.-2012 14:12:14  Without any alter session before, because that will change the settings.
Regards.
