> Key: SPARK-31335
> URL: https://issues.apache.org/jira/browse/SPARK-31335
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Kent Yao
> Assignee: Apache Spark
> Priority: Major
>
> {code:java}
> Evaluate an expression and handle certain types of execution errors by
> returning NULL.
> In cases where it is preferable that queries produce NULL instead of failing
> when corrupt or invalid data is encountered, the TRY function may be useful
> especially when ANSI mode is on and the users need null-tolerant on certain
> columns or outputs.
> AnalysisExceptions will not handle by this, typically errors handled by TRY
> function are:
> * Division by zero,
> * Invalid casting,
> * Numeric value out of range,
> * e.t.c
> {code}
