Takeshi Yamamuro updated SPARK-23179:
-------------------------------------
Parent Issue: SPARK-30374 (was: SPARK-27764)
> Support option to throw exception if overflow occurs during Decimal arithmetic
> ------------------------------------------------------------------------------
>
> Key: SPARK-23179
> URL: https://issues.apache.org/jira/browse/SPARK-23179
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 2.3.0
> Reporter: Marco Gaido
> Assignee: Marco Gaido
> Priority: Major
> Fix For: 3.0.0
>
>
> 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).
