kawadakk opened a new issue, #13558:
URL: https://github.com/apache/datafusion/issues/13558
### Describe the bug
Referencing a column from a certain form of `select` and `order by` clauses
at the same time causes an error saying "projections require unique expression
names".
### To Reproduce
```
> create table foo as values (1, 2), (3, 4), (5, 6);
0 row(s) fetched.
Elapsed 0.002 seconds.
> select cast(column1 as text) from foo order by column1;
Error during planning: Projections require unique expression names but the
expression "CAST(foo.column1 AS Utf8)" at position 0 and "foo.column1" at
position 1 have the same name. Consider aliasing ("AS") one of them.
```
### Expected behavior
Successful query execution
### Additional context
DataFusion v43.0.0
