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.
src_converted_to_full_column = !removeNullable(arg.type)->equals(*removeNullable(res_type));
                    if (src_converted_to_full_column)
                        arg.column = arg.column->index(col_low_cardinality->getIndexes(), 0);
                    else
                        res_indexes = col_low_cardinality->getIndexesPtr();
                    tmp_rows_count = arg.column->size();
                }
                
                converted_column = wrapper(args, res_type, nullable_source, tmp_rows_count);
            }
            if (to_low_cardinality)
            {
                auto res_column = to_low_cardinality->createColumn();
                auto * col_low_cardinality = typeid_cast<ColumnLowCardinality *>(res_column.get());
                if (from_low_cardinality && !src_converted_to_full_column)
                {
                    col_low_cardinality->insertRangeFromDictionaryEncodedColumn(*converted_column, *res_indexes);
                }
                else
                    col_low_cardinality->insertRangeFromFullColumn(*converted_column, 0, converted_column->size());
                return res_column;
            }
            else if (!src_converted_to_full_column)
                return converted_column->index(*res_indexes, 0);
            else
                return converted_column;
        };
    }
