Gang Tim Liu commented on HIVE-3795: ------------------------------------ comments in phabricator. > 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 > Assignee: Xiao Jiang > Priority: Trivial > Attachments: HIVE-3795.1.patch.txt > > > 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. -- This message is automatically generated by JIRA.
