Barbara, You could look at using the add_months() function... Just add -12,000 months like the statement below: SQL> select sysdate, add_months(sysdate, -12000) from dual; SYSDATE ADD_MONTHS(SYSDATE,- -------------------- -------------------- 24-mar-2004 08:42:07 24-mar-1004 08:42:07 Regards, Mark. Barbara Baker <barbarabbaker@yah To: oracle-l@xxxxxxxxxxxxx oo.com> cc: Sent by: Subject: update year in date column oracle-l-bounce@fr eelists.org 24/03/2004 07:00 Please respond to oracle-l 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) JServer Release 9.2.0.4.0 - Production DOC> CUSNO CUSNAME CRDATE DOC>---------- ----------------------------------- ---------- DOC> 798489 GILBERT, ROSS 09/16/2099 DOC> 826744 HOEFLER, MATT 10/08/2099 DOC> 795126 FORT, JOETTA 09/08/2099 DOC>*/ SQL> SQL> ---select to_date(to_char(crdate,'MM/DD/YYYY')) from customer where cusno=798489; SQL> ---update advdb.custtest_barb SQL> ---set crdate= to_char(crdate,'MM/DD/YYYY')) SQL> ---from customer where cusno=798489; SQL> SQL> select to_date(to_char(crdate,'ddmmyyyy')-1000),'MM/DD/YYYY') 2 from customer where cusno=798489; select to_date(to_char(crdate,'ddmmyyyy')-1000),'MM/DD/YYYY') * ERROR at line 1: ORA-00923: FROM keyword not found where expected SQL> SQL> SQL> --- these both work SQL> select to_char(crdate,'ddmmyyyy') from custtest_barb where cusno=798489; TO_CHAR( -------- 16092099 SQL> select to_char(crdate,'ddmmyyyy') - 1000 from custtest_barb where cusno=798489; TO_CHAR(CRDATE,'DDMMYYYY')-1000 ------------------------------- 16091099 Thank for any assistance.
