SELECT that returns list of values not occurring in any row

Question

Query:

select id from users where id in (1,2,3,4,5)

If the users table contains ids 1, 2, 3, this would return 1, 2, and 3. I want a query

Answer 1

Sorry, I cannot add comments, @Austin,

You have my +1.

Anyway, not sure if this works on mysql, but change all that atomic selects concatenated unions for a value set, so you have something like that:

SELECT id FROM (
    VALUES (1), (2), (3), (4), (5)
) AS list(id)
LEFT JOIN users USING (id)
WHERE users.id IS NULL
