Update Multiple Fields With 'OR'

Is there a better way to do this (more efficient).

I have up to 200 items to update per query, the id's are not sequential. Using up 200 (well 199) OR's in a single query doesnt strike me as being the best way to do this. All the fields get set to the same value.

# Example
UPDATE table SET value=value WHERE id=11 or id=23 or id=31 or id=74 or id=56 or id=96;
# Up to 200 fields

Or am I stuck with this query? (which works).
