englefly opened a new pull request, #35610:
URL: https://github.com/apache/doris/pull/35610

   ## Proposed changes
   this pr improves #34542, when the real data type is date-like type.
   
   Some users are likely to define date(datetime) column as Varchar type.
   when estimating the selectivity of predicate like A>'2020-01-01', if nereids 
regards A and '2020-01-01' as date type, the sel is more accurate than that as 
string type.
