Will this do ?
Alter session set nls_date_format='DD-MON-CYYYY-HH24:MI:SS'; select * from mytabdate;

    CUSTNO CRDATE

---------- ---------------------
         1 16-SEP- 2099 00:00:00
         1 08-OCT- 2099 00:00:00

update mytabdate
set crdate =

to_date(to_char(crdate, 'DD-MON-')||
to_char(to_number(to_char(crdate,'yyyy'))-100) ||
to_char(crdate, ' HH24:MI:SS') ,'DD-MON-YYYY HH24:MI:SS')

/

2 rows updated.

 select * from mytabdate;

    CUSTNO CRDATE

---------- ---------------------
         1 16-SEP- 1999 00:00:00
         1 08-OCT- 1999 00:00:00

Subject: update year in date column

OK, I'm just going to bite the bullet and claim total ignorance here and see if someone takes pity on me :(
(sad face a nice touch, eh?)

Someone has accidently updated 378 records in the customer table. The date changed from 1999 to 2099. I need to change just the year back to 1999 for these records. (I'd like to keep the time stamp, if possible. The month and day are correct.) I looked on metalink, google, and asktom. Some nice examples, but not what I really need.

Thought I'd be clever and subtract 1000 from the date. This works, but I don't know how to get it formatted back into a date.

I'd prefer just sqlplus, but will use pl/sql if necessary.

Here's what I've done so far:
(solaris 9 oracle 9.2.0.4)
