siddharthteotia commented on issue #5016: Support alias replacement in 
PinotQuery
URL: https://github.com/apache/incubator-pinot/pull/5016#issuecomment-578888339
 
 
   How are these queries going to be handled?
   
   SELECT C1 AS ALIAS_C1, C2 AS ALIAS_C2, ADD(C1, C2) FROM Foo
   
   Should the user provide the aliases as arguments to ADD transform function? 
Or should they be allowed to?
   
   I think the standard is to provide original column names to functions or any 
part of the query and the users should not do alias replacement themselves. It 
will be good to add a test case for this.
