duongcongtoai opened a new issue, #10656:
URL: https://github.com/apache/datafusion/issues/10656
### Describe the bug
Given this slt
```
statement ok
CREATE TABLE temp
AS VALUES
([struct(1,2)])
;
query ?
select unnest(column1) as struct_elem from temp;
----
{c0: 1, c1: 2}
```
The code will throw error
```
Internal error: unnest on struct can ony be applied at the root level of
select expression
```
### To Reproduce
perform unnest on List(Struct) column, but with unnest as a child expr (e.g
an alias)
### Expected behavior
The type beling unnested is with type List, and unnesting(List(Struct))
should result into Struct correctly
