to_date(SYSDATE,'DD-MON-YYYY RR')

Hi Friends,

I am trying to work out what the 'RR' Parameter in the to_data function represents. Can anyone please explain.

Also..

I entered the following in sqlplus :

select
to_date(SYSDATE,'DD-MON-YYYY RR')
from dual

and got the following error

ORA-01840: input value not long enough for date format
anybody know why?

What would be the correct syntax to display 'RR' as part of a date ?
What is it ?

Many Thanks

Suresh

Try either one of these:

select to_char(sysdate, 'DD-MON-RRRR') from dual;

select to_char(sysdate, 'DD-MON-YYYY') from dual;

to_char and not to_date

Good luck.

Hi,

These both outputted the same result.

Can you Please explain the difference between RRRR and YYYY

Thanks

Suresh

Hi, you must try this

to_date(sysdate,'DD-MON-RRRR')

Greets,

select to_char(to_date('27-OCT-98', 'DD-MON-RR'), 'YYYY') "Year"
from dual;

Would return the previous century:

Year
----
1998

On the other hand:

select to_char(to_date('27-OCT-98', 'DD-MON-YY'), 'RRRR') "Year"
from dual;

Would return current century

Year
----
2098

Hi,
RR code is used to round the century based on the current year and 2 digit year.
If current year is >=50 and 2digit year is <50,it rounds to next century.
If current year is <50 and 2digit year is>50,it rounds to previous century.
If the current year is >=50 and 2digit year is >=50 the century remains unchanged.
If the current year is <50 and 2digit year is <50 the century remains unchanged.

regards

Cheers..
