---------------------------------

             Summary: subquery's column alias can not be the same with partition column name

                 Key: HIVE-15495

          Components: Query Planning
    Affects Versions: 1.1.0
            Reporter: chenyukang


case:
create table testkk5(a string) partitioned by(dt string);
alter table testkk5 add partition(dt="1");
hive> select * from (select a as dt from testkk5 where dt="1") t1 where t1.dt="2";
