Gengliang Wang updated SPARK-35161:
-----------------------------------
Issue Type: Umbrella (was: New Feature)
> Safe version SQL functions
> --------------------------
>
> 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
> 2. The result can be more reasonable. For example, the result of the
> following operation is terrible
> {code:java}
> 2147483647 + 2 => -2147483647
> CAST(2147483648L AS INT) => -2147483648
> {code}
> Having the safe version SQL functions provides an alternative solution for
> handling such cases
> {code:java}
> TRY_ADD(2147483647, 2) => null
> TRY_CAST(2147483648L AS INT) => null
> {code}
