Subject [jira] [Created] (HIVE-8925) Move semantic correctness check to parser for having by queries
Date Thu, 20 Nov 2014 16:00:35 GMT
Ashutosh Chauhan created HIVE-8925:
--------------------------------------

             Summary: Move semantic correctness check to parser for having by queries
                 Key: HIVE-8925
                 URL: https://issues.apache.org/jira/browse/HIVE-8925
             Project: Hive
          Issue Type: Improvement
          Components: Diagnosability, Parser
            Reporter: Ashutosh Chauhan


For invalid queries like
{code}
select * from t1 having c1 > 0;
{code}
Currently semantic correctness check is done in semantic analyzer, but this can be caught
right at parse time by tightening up our grammar.
