URL: https://github.com/apache/datafusion/issues/11766
**Is your feature request related to a problem or challenge? Please describe
what you are trying to do.**
```shell
datafusion-cli
```
Then run
```sql
DataFusion CLI v40.0.0
> create table foo as values ('value1', arrow_cast('one', 'Utf8View')),
('value1', arrow_cast('two', 'Utf8View'));
0 row(s) fetched.
> select column2||'ff' from foo;
Internal error: Data type Utf8View not supported for binary operation
'concat_elements' on string arrays.
This was likely caused by a bug in DataFusion's code and we would welcome
that you file an bug report in our issue tracker
```
**Describe the solution you'd like**
I would like the query to work
**Describe alternatives you've considered**
We can probably get the query to work by fixing the coercion logic to
coerce to `Utf8`, but that will be less efficient than implementing native
StringView support for `concat`
The coercion is here:
https://github.com/apache/datafusion/blob/6e2ff2955d96cacba905d24993353c7e5fe0cf93/datafusion/expr/src/type_coercion/binary.rs#L116-L122
The physical expression implementation starts here
https://github.com/apache/datafusion/blob/6e2ff2955d96cacba905d24993353c7e5fe0cf93/datafusion/physical-expr/src/expressions/binary.rs#L661
