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.
