Ashutosh Chauhan commented on HIVE-13583:
-----------------------------------------

Are you suggesting to add {{UNKNOWN}} as a keyword in grammar.  I am not sure how is that
connected to this jira which is about supporting search conditions of form : "<predicate>
is not true; It should be possible (infact, desired that) we add this support with current
grammar.
Even if {{UNKNOWN}} is specified in standard discussion on how and when to add it should be
a separate effort.

> This is a part of the SQL:2011 Analytics Complete Umbrella JIRA HIVE-13554. Support for
various forms of search conditions are mandatory in the SQL standard. For example, "<predicate>
is not true;" Hive should support those forms mandated by the standard.
