KonarzewskiP opened a new pull request, #30510:
URL: https://github.com/apache/shardingsphere/pull/30510

   Fixes #29188.
   
   Changes proposed in this pull request:
     - add test case to cover scenario:
   
   ```sql
   SELECT state_desc  
    , file_type_desc  
    , COUNT(*) AS [count]  
    , SUM(CASE  
      WHEN state = 5 AND file_type=0 THEN 128*1024*1024  
      WHEN state = 5 AND file_type=1 THEN 8*1024*1024  
      WHEN state IN (6,7) THEN 68*1024*1024  
      ELSE file_size_in_bytes  
       END) / 1024 / 1024 AS [on-disk size MB]   
   FROM sys.dm_db_xtp_checkpoint_files  
   GROUP BY state, state_desc, file_type, file_type_desc  
   ORDER BY state, file_type
   ```
   - The following test case was covered in this [PR](https://github.com/apache/shardingsphere/pull/30258)
   ```sql
   SELECT PersonName, Friends
   FROM (
       SELECT
           Person1.name AS PersonName,
           STRING_AGG(Person2.name, '->') WITHIN GROUP (GRAPH PATH) AS Friends,
           LAST_VALUE(Person2.name) WITHIN GROUP (GRAPH PATH) AS LastNode
       FROM
           Person AS Person1,
           friendOf FOR PATH AS fo,
           Person FOR PATH  AS Person2
       WHERE MATCH(SHORTEST_PATH(Person1(-(fo)->Person2)+))
       AND Person1.name = 'Jacob'
   ) AS Q
   WHERE Q.LastNode = 'Alice'
   ```

   Since this PR does not change any g4 or visitor logic, it can be considered that these cases are already supported. I will close this PR and welcome other issues.

Review Comment:
   Does this PR not involve any changes to G4 or visit logic? In other words, the SQL on the issue is already supported, in this case, we just need to leave a message on the issue, and the community volunteer will close the issue.
