   ### What problem does this PR solve?
   
   Issue Number: close #xxx
   
   Related PR: #51562
   
   Problem Summary:
   
   When you execute the statement 
   `show alter table materialized view from your_db_name where IndexName = 
'xxx';`, you can get the result : 
   ```
   *************************** 1. row ***************************
             JobId: 1752222159622
         TableName: test_show_alter_table_tbl
        CreateTime: 2025-07-11 16:23:30
        FinishTime: 2025-07-11 16:23:30
     BaseIndexName: test_show_alter_table_tbl
   RollupIndexName: a_mv
          RollupId: 1752222159623
     TransactionId: 3
             State: FINISHED
               Msg:
          Progress: NULL
           Timeout: 2592000
   ```
   It's confused for user, because the result doesn't contain **IndexName** but 
user can show the result.
   
   The second problem is the value of IndexName, you can get all materialized 
views whatever you set in IndexName, for example : `where IndexName = 'yyy'` 
and `where IndexName = 'zzz'`,  the two where clauses can return all 
materialized views both.
   
   So we should fix it.
