2010YOUY01 opened a new issue, #24421:
URL: https://github.com/apache/datafusion/issues/24421

   ### Describe the bug
   
   Producer in `datafusion-cli`:
   
   ```sh
   > CREATE EXTERNAL TABLE grouping_set_ordered (
     a0 INTEGER,
     a INTEGER,
     b INTEGER,
     c INTEGER,
     d INTEGER
   )
   STORED AS CSV
   WITH ORDER (c)
   LOCATION 
'/Users/yongting/Code/datafusion-grouping-sets-ordering/datafusion/core/tests/data/window_2.csv'
   OPTIONS ('format.has_header' 'true');
   
   > SELECT c
   FROM (
     SELECT b, c, grouping(b, c) AS gid
     FROM grouping_set_ordered
     GROUP BY GROUPING SETS ((b, c), (c))
   )
   ORDER BY c
   LIMIT 10;
   +---+
   | c |
   +---+
   | 0 |
   | 1 |
   | 2 |
   | 3 |
   | 4 |
   | 5 |
   | 6 |
   | 7 |
   | 8 |
   | 9 |
   +---+
   10 row(s) fetched.
   Elapsed 0.002 seconds.
   ```
   
   Because we have `grouping set ((b,c), (c))`, each distinct `c` value should 
appear twice in the output
   ```sh
   D SELECT b,c
     FROM (
         SELECT b, c, grouping(b, c) AS gid
         FROM grouping_set_ordered
         GROUP BY GROUPING SETS ((b, c), (c))
     )
     ORDER BY c
     LIMIT 10;
   ┌───────┬───────┐
