>                 Key: SPARK-35161
>                 URL: https://issues.apache.org/jira/browse/SPARK-35161
>             Project: Spark
>          Issue Type: Umbrella
>          Components: SQL
>    Affects Versions: 3.2.0
>            Reporter: Gengliang Wang
>            Priority: Major

> Create new safe version SQL functions for existing SQL functions/operators, which returns NULL if overflow/error occurs. So that:
> 1. Users can manage to finish queries without interruptions in ANSI mode.
> 2. Users can get NULLs instead of unreasonable results if overflow occurs when ANSI mode is off.
> For example, the behavior of the following SQL operations is unreasonable:
> {code:java}
> 2147483647 + 2 => -2147483647
> CAST(2147483648L AS INT) => -2147483648
> {code}
> With the new safe version SQL functions:
> {code:java}
> TRY_ADD(2147483647, 2) => null
> TRY_CAST(2147483648L AS INT) => null
> {code}
