[jira] [Created] (SPARK-23179) Support option to throw exception if overflow occurs

Marco Gaido created SPARK-23179:
-----------------------------------

             Summary: Support option to throw exception if overflow occurs
                 Key: SPARK-23179
                 URL: https://issues.apache.org/jira/browse/SPARK-23179
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.3.0
            Reporter: Marco Gaido


SQL ANSI 2011 states that in case of overflow during arithmetic operations, an exception should be thrown. This is what most of the SQL DBs do (eg. SQLServer, DB2). Hive currently returns NULL (as Spark does) but HIVE-18291 is open to be SQL compliant.

I propose to have a config option which allows to decide whether Spark should behave according to SQL standards or in the current way (ie. returning NULL).
