> 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.
