Trivial. See the attached tool that is one of 61 in the Job Spy plugin.

For you, personally, since you wish to match on book ID as the key rather than on a custom column as the key, simply create a temporary custom column of type INT, and use Calibre Search & Replace to copy ID to your temporary ID column. Import you CSV, match on tmp ID, then vary the "update column" as you please.
