There are a few dates in the database date column which are added incorrectly... The year is 0003 instead of 2003... I want to keep the dates but change the year on those dates...

example: 22-Mar-0003 should be 22-mar-2003 ...
How do I write the update statement?

I think a better thing to do is find out the cause of these bad dates (well, it's because you are using 2 digits instead of 4 digits for dates of course, but WHERE is this happening?).

Forms?
front-end tool?
third-party product?
java/perl/etc?
