LiBinfeng-01 opened a new pull request, #22947:
URL: https://github.com/apache/doris/pull/22947

   ## Proposed changes
   
   Problem: 
   When querying sql with expression like count(case when...) Planner would 
return an implicitly cast error
   Example:
   select count(case true when true then null else null end) from t;
   Reason:
   When analyzing count function, it would expect return type of case when is a 
scalartype, if not, it would cast them into scalartype implicitly. 
   Solusion:
   Change logic of arguments type and make sure it would not be casted to 
array_type
