Otherwise the following query will be optimized incorrectly:
SELECT
*,
any(arrayJoin([[], []]))
FROM numbers(1)
GROUP BY number
And the result will be:
┌─number─┬─arrayJoin(array(array(), array()))─┐
│ 0 │ [] │
│ 0 │ [] │
└────────┴────────────────────────────────────┘
While should be:
┌─number─┬─any(arrayJoin(array(array(), array())))─┐
│ 0 │ [] │
└────────┴─────────────────────────────────────────┘
