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
