I 'm not sure why you would be subtracting 1000 from the bad date, even if
you were actually subtracting years and not days. If I 'm understanding you,
you really want to subtract 100 years from the bad dates. Try this: update
custtable set crdate = add_months(crdate, -(12*100));

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)

JServer Release 9.2.0.4.0 - Production

Thank for any assistance.
