Question of the Day

ORDER BY alias

There is a table tmp_tab:

CREATE TABLE tmp_tab (
id int,
val int
);
INSERT INTO tmp_tab VALUES
(1, 1),

(3, 3),
(4, 4),
(5, 5);
You want to order the rows ids by the following expression:
    ISNULL(val, id) + 1
Which of the following queries produces the expected ordering and why? (Select all correct)
