Word for a change that only applies once

I'm trying to remember the word for a function that can be applied multiple times to the same data set but only makes its change once. I've got a Rails migration that sets some data, but only if that data isn't set. So if it is run multiple times it only does work once.

Are you thinking about the word "idempotent"? (I'm frantically looking for my Category Theory book ...)
