My query selects results correctly using ORDER BY CASE.
I would like to randomize the results within EACH case. i.e.
ORDER BY CASE WHEN apples (randomize) THEN 1 WHEN pears (randomize) THEN 2, etc.
So my results are still ordered by each case but within the results PER case they are random, each time the query is run.
You can try
ORDER BY CASE, RAND().RAND()generates a random number, of course.However, I heard somewhere that shuffling elements in SQL is not quite the most efficient way and it is better to randomize elements in PHP. But randomizing them per case is not a trivial task. (PHP
rand()function)
