Subject [jira] [Created] (HIVE-3795) NPE in SELECT when WHERE-clause is an and/or/not operation involving null
Date Wed, 12 Dec 2012 17:18:19 GMT
Xiao Jiang created HIVE-3795:
--------------------------------

             Summary: NPE in SELECT when WHERE-clause is an and/or/not operation involving
null
                 Key: HIVE-3795
                 URL: https://issues.apache.org/jira/browse/HIVE-3795
             Project: Hive
          Issue Type: Bug
          Components: Query Processor
            Reporter: Xiao Jiang


Sometimes users forget to quote date constants in queries. For example, SELECT * FROM some_table
WHERE ds >= 2012-12-10 and ds <= 2012-12-12; . In such cases, if the WHERE-clause contains
and/or/not operation, it would throw NPE exception. That's because PcrExprProcFactory in ql/optimizer
forgot to check null.
