found no similar issues.
   
   
   ### Description
   
    There are a lot of implicit casts in doris currently.
   
    eg.  select * from t1 where id = '1'; 
   
   When id is int, an implicit conversion occurs, converting varchar to int. 
But the implicit conversion information is not reflected in explain and explain 
verbose.
   
   Implicit conversion information is now displayed in explain verbose
   
   ### Solution
   
   Add the verbose information of the query in the executor of ConnectContext, 
judge whether it is verbose in toSql of CastExpr, and display the cast 
information for verbose direct and implicit conversion
