> CREATE TABLE test (id INT, val INT);
> INSERT INTO test VALUES (1,1);
> INSERT INTO test VALUES (2,2);
> INSERT INTO test VALUES (3,3);
> INSERT INTO test VALUES (4,4);
> SELECT id FROM (SELECT id, val FROM test ORDER BY val DESC);
>  {code}
> Looks like CALCITE-2798 removes the sorting in sub-queries too aggressively.
