Hi All,
When I was trying to execute the following statement, it fails. Can anyone tell me why?

SQL> ALTER DATABASE SET TIME_ZONE='+5:30';
ALTER DATABASE SET TIME_ZONE='+5:30'
*
ERROR at line 1:
ORA-02231: missing or invalid option to ALTER DATABASE

I checked the syntax with the documentation, everything appear to be fine.

I even tried this, which also fails.

SQL> ALTER DATABASE SET TIME_ZONE=
2 'Europe/London';
ALTER DATABASE SET TIME_ZONE=
*
ERROR at line 1:
ORA-02231: missing or invalid option to ALTER DATABASE

All these were tried from sysdba login.

Thanks in advance.

Doesn't work

It says :
SQL> alter database set time_zone '+5:30';
alter database set time_zone '+5:30'
*
ERROR at line 1:
ORA-00927: missing equal sign

Sorry, checked the docs and found indeed the equal sign was needed. Found my original answer in a syntax-definition on a website I frequently use; never tested it though (don't want to upset my collegues Smile

This might be a restriction ( and lasttime i read, is supposed to be fixed in 10g).
Check your database.
There should columns that are using the present local timezone.
You cannot alter the database timezone, without cleaning / dropping those columns.

Honestly, a google search / quick look into docs might help.
Better wordings, better explained and documented.
