Jibing-Li opened a new pull request, #22458:
URL: https://github.com/apache/doris/pull/22458

   The error message was not good for not exist column while show column stats:
   ```
   MySQL [hive.tpch100]> show column stats `lineitem` (l_extendedpric);
   ERROR 1105 (HY000): errCode = 2, detailMessage = Unexpected exception: null
   ```
   
   This pr show a meaningful message:
   ```
   mysql> show column stats `lineitem` (l_extendedpric);
   ERROR 1105 (HY000): errCode = 2, detailMessage = Column: l_extendedpric not 
exists
   ```
