Description

I don't know any other database that lacks this type of function (even SQLite has it):

REPLACE(in, search)
REPLACE(in, search, replace)

But according to the Derby docs, this doesn't exist in Derby:

http://db.apache.org/derby/docs/10.8/ref/rrefsqlj29026.html

It would be quite simple to implement, I guess. Yet really useful for many people. Some documentation examples from other databases:
