Pengcheng Xiong created HIVE-11815:
--------------------------------------
Summary: Correct the column/table names in subquery expression when create a view
Key: HIVE-11815
URL: https://issues.apache.org/jira/browse/HIVE-11815
Project: Hive
Issue Type: Sub-task
Reporter: Pengcheng Xiong
Assignee: Pengcheng Xiong
Right now Hive does not quote column/table names in subquery expression when create a view. For example
{code}
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

Time taken: 0.063 seconds, Fetched: 3 row(s)
hive> select * from tcv;
FAILED: SemanticException line 1:63 character '@' not supported here
line 1:84 character '@' not supported here
line 1:89 character '@' not supported here in definition of VIEW tcv [
