adriangb opened a new issue, #19410:
URL: https://github.com/apache/datafusion/issues/19410

   ### Describe the bug
   
   In `main` running this query fails with
   
   ```
   Error during planning: Column in ORDER BY must be in GROUP BY or an 
aggregate function: While expanding wildcard, column "Count" must appear in the 
GROUP BY clause or must be part of an aggregate function, currently only "t.x, 
count(Int64(1)), count" appears in the SELECT clause satisfies this requirement
   ```
   
   ### To Reproduce
   
   ```sql
   > with t as (select 'foo' as user_agent)
   select user_agent "User Agent", count(*) as "Count"
   from t
   where user_agent not like 'Mozilla%'
   group by "User Agent"
   order by 2 desc;
   Error during planning: Column in ORDER BY must be in GROUP BY or an 
aggregate function: While expanding wildcard, column "Count" must appear in the 
GROUP BY clause or must be part of an aggregate function, currently only 
"t.user_agent, count(Int64(1)), User Agent, count" appears in the SELECT clause 
satisfies this requirement
   ````
   
   ### Expected behavior
   
   Query succeeds.
   
   In v50:
   
   ```
   ❯ datafusion-cli
   DataFusion CLI v50.0.0
   > with t as (select 'foo' as x)
   select x, count(*) as "Count"
   from t
   group by x
   order by 2 desc;
   +-----+-------+
   | x   | Count |
   +-----+-------+
   | foo | 1     |
   +-----+-------+
   1 row(s) fetched.
   Elapsed 0.003 seconds.
   ```
   
   In DuckDB:
   
   ```
   ❯ duckdb
   DuckDB v1.3.2 (Ossivalis) 0b83e5d2f6
   Enter ".help" for usage hints.

   D with t as (select 'foo' as x)
     select x, count(*) as "Count"
     from t
     group by x
     order by 2 desc;
   ┌─────────┬───────┐
   │    x    │ Count │
   │ varchar │ int64 │
   ├─────────┼───────┤
   │ foo     │   1   │
   └─────────┴───────┘
   ```
