1. Why is NLS_DATE_FORMAT = 'DD MON RRRR'?
It should be NLS_DATE_FORMAT = 'DD/MM/YY' or not?
2. If Oracle iAS can specify the NLS session parameter, how can I do?
(I would not like to specify its from my code as using DBMS_SESSION.SET_NLS or other)
PS. I know where I can set NLS parameter at SESSION and SYSTEM level but I'm confused why NLS_DATE_FORMAT='DD MON RRRR' was returned by Oracle iAS that I never set the specific NLS paramter on the server. --by default NLS_DATE_FORMAT is 'DD-MON-RR' right?
