----------------------------------

             Summary: An exception should be raised if the result is outside the range of decimal
                 Key: HIVE-18291
                 URL: https://issues.apache.org/jira/browse/HIVE-18291
             Project: Hive
          Issue Type: Sub-task
    Affects Versions: 2.3.0
            Reporter: Marco Gaido


Citing SQL:2011 on page 27 available at http://standards.iso.org/ittf/PubliclyAvailableStandards/c053681_ISO_IEC_9075-1_2011.zip:


{noformat}
If the result cannot be represented exactly in the result type, then whether it is rounded
or truncated is implementation-defined. An exception condition is raised if the result is
outside the range of numeric values of the result type, or if the arithmetic operation
is not defined for the operands.
{noformat}

Currently Hive is returning NULL instead of throwing an exception if the result is out of range, eg.:

{code}
> select 1000000000000000000.000001*1000000000000000000.000001;
+-------+
|  _c0  |
+-------+
| NULL  |
+-------+
{code}
