Describe the bug
Interval data type is not passed correctly from subquery
Does it reproduce on recent release?
Yes, tested on 21.6.5.37.
How to reproduce
SELECT
toIntervalDay(5) AS interval,
now() + interval AS res
┌─interval─┬─────────────────res─┐
│ 5 │ 2021-07-03 13:11:45 │
└──────────┴─────────────────────┘But if I wrap interval calculation in subquery:
SELECT
(SELECT toIntervalDay(5)) AS interval,
now() + interval AS res
Received exception from server (version 21.6.5):
Code: 70. DB::Exception: Received from localhost:9000. DB::Exception: Conversion from Int8 to IntervalDay is not supported: While processing CAST(5, 'IntervalDay') AS interval, now() + interval AS res.Expected behavior
Both queries should work the same way.
