--------------------------------------
Summary: Allow the symmetric and asymmetric keywords to the
between predicate
Key: HIVE-15985
URL: https://issues.apache.org/jira/browse/HIVE-15985
Project: Hive
Issue Type: Sub-task
Reporter: Carter Shanklin
When testing whether a number c3 is between c1 and c2, sometimes you don't know
when c1 <= c2. In this case it is useful to be able to run "c3 between
symmetric c1 and c2" which handles the case of c1 > c2. SQL allows the keywords
of symmetric and asymmetric to be defined, with asymmetric used if no keyword
is supplied. SQL standard reference: section 8.3
