WingsGo opened a new issue #2392: Support convert INT type to DATE type
URL: https://github.com/apache/incubator-doris/issues/2392
 
 
   Now, users can change column type from INT type to DATE type by ALTER TABLE table_name MODIFY COLUMN k1 DATE.
   For example:
   before convert: "20191205" (INT)
   after convert: "2019-12-05" (DATETIME)
   If the value of int type is invalid such as  9999, after convert it will set to NULL
