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

             Summary: Implement SAFE_NEGATE function (enabled for BigQuery)
                 Key: CALCITE-5766
                 URL: https://issues.apache.org/jira/browse/CALCITE-5766
             Project: Calcite
          Issue Type: Sub-task
            Reporter: Tanner Clary
            Assignee: Tanner Clary


Add support for SAFE_NEGATE in BigQuery.
SAFE_NEGATE: Equivalent to the unary minus operator (-), but returns NULL if overflow occurs.

Example #1: {{SELECT SAFE_NEGATE(3)}} would return {{-3}}.
Example #2: {{SELECT SAFE_NEGATE(-9223372036854775808)}} would return {{NULL}} because of overflow.
