[jira] [Commented] (HIVE-1449) Table aliases in order by clause lead to semantic analysis failure

["sukhendu chakraborty (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-1449?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13278101#comment-13278101 ] 

sukhendu chakraborty commented on HIVE-1449:
--------------------------------------------

I have slightly different symptoms but they seem to be related:


select  dist Group1 , count(*) x from cars_tab order by dist;
FAILED: Error in semantic analysis: Line 1:43 Invalid table alias or column reference dist

However, if I use the column alias (Group1), it passes:
select  dist Group1 , count(*) x from cars_tab order by Group1;

> A simple statement of the form
> select a.account_id, count(1) from tmp_ash_test2 a group by a.account_id order by a.account_id;
> throws a sematic analysis exception
> where as
> select a.account_id, count(1) from tmp_ash_test2 a group by a.account_id order by account_id;
> works fine (the second query does not have the table alias a in the order by clause.
