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.
const IColumn & column_from,
        IColumn & column_to,
        const ISerialization & serialization_from,
        size_t input_rows_count,
        const PaddedPODArray<UInt8> * null_map = nullptr,
        const IDataType * result_type = nullptr)
    {
        static_assert(std::is_same_v<StringColumnType, ColumnString> || std::is_same_v<StringColumnType, ColumnFixedString>,
                "Can be used only to parse from ColumnString or ColumnFixedString");
        if (const StringColumnType * col_from_string = checkAndGetColumn<StringColumnType>(&column_from))
        {
            column_to.reserve(input_rows_count);
            FormatSettings format_settings;
            for (size_t i = 0; i < input_rows_count; ++i)
            {
                if (null_map && (*null_map)[i])
                {
                    column_to.insertDefault();
                    continue;
                }
                const auto & val = col_from_string->getDataAt(i);
                ReadBufferFromMemory read_buffer(val.data, val.size);
                serialization_from.deserializeWholeText(column_to, read_buffer, format_settings);
