Thanks much for any help you may provide. I am running oracle 7.3.x.x and have set the nls_date_format to dd-mon-rr. Here's the proof:

     > select    substr(name,1,20),       substr(value,1,20)
          from sys.v_$parameter  where name like '%nls_date%'

        nls_date_format               2 DD-MON-RR

I have created a 1 row, 1 column table:
> desc test_y2k

    col1 date

Here is all that is in the table:
> select col1 from test_y2k;

   05-JAN-11 The "RR" is not acting as expected when I perform the following query. I thought I would get 2011
and not 1911.

>select DECODE(to_char(col1 , 'YYYY-MON-DD'),

                                     '2011-JAN-05'   ,    '2011',
                                     '1911-JAN-05'   ,    '1911',
                                     'OTHER'   )

    from test_y2k ;

I get:
1911

I get this even if I put RRRR instead of YYYY I get 1911. What's wrong! Thanks Again,
Frank S.
