   ### Search before asking

   ### Version

   ### What's Wrong?
   
   Execution of a query statement having a `COUNT` aggregate function which could trigger a materialized view will get the unknown column exception, and the column name corresponds to the rewrited materialized column of the parameter of aggregate function.

   ### How to Reproduce?
   
   1. 
   ```sql
   CREATE TABLE case_tbl (col1 varchar, col2 varchar, col3 int)
   DISTRIBUTED BY HASH(col3)
   BUCKETS 3
   PROPERTIES(
       "replication_num"="1"
   );
   ```
   
   2. 
   ```sql
   create materialized view case_mv as select col2, count(col1) as c from d_test2 d_test2 group by col1, col2;
   ```
   
   3.
   ```sql
   select col2, count(col1) as c from d_test2 d_test2 group by col1, col2;
   ```
