Tanner Clary created CALCITE-5735:
-------------------------------------

             Summary: Implement BigQuery SAFE_MULTIPLY function
                 Key: CALCITE-5735
                 URL: https://issues.apache.org/jira/browse/CALCITE-5735
             Project: Calcite
          Issue Type: Sub-task
            Reporter: Tanner Clary
            Assignee: Tanner Clary


Add support for SAFE_MULTIPLY in BigQuery.
SAFE_MULTIPLY: Equivalent to the multiplication operator '*', but returns NULL if overflow occurs.

Example #1: {{SELECT SAFE_MULTIPLY(3, 4)}} would return {{12}}.
Example #2: {{SELECT SAFE_MULTIPLY(2^63, 2)}} would return {{NULL}} because of overflow.
