[GitHub] [incubator-doris] Seaven removed a comment on issue #2123: If the parameter of ifnull is datetime, return wrong type

Seaven removed a comment on issue #2123: If the parameter of ifnull is datetime, return wrong type
URL: https://github.com/apache/incubator-doris/issues/2123#issuecomment-552782707
 
 
   There are several reasons for the question:
   1.The ifnull method does not support check for date type
   2.If the parameter type of ifnull method is different, maybe will return unpredictable result, such as ifnull(b.k10, b.k9), ifnull(b.k10, b.k11).....
