You have to provide the following information whenever possible.

**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**

```sql
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:

```sql
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.
{
        if (from < 0)
            return 0;
        return static_cast<ToType>(std::min(time_t(from), time_t(0xFFFFFFFF)));
    }
};
