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:
