Description

Right now Hive does not quote column/table names in subquery expression when create a view. For example

hive>
    > create table tc (`@d` int);
OK
Time taken: 0.119 seconds
hive> create view tcv as select * from tc b where exists (select a.`@d` from tc a where b.`@d`=a.`@d`);
OK
Time taken: 0.075 seconds
hive> describe extended tcv;
OK
@d                  	int

hive> select * from tcv;
