> ---------------------------------------------
>
> Key: SPARK-33989
> URL: https://issues.apache.org/jira/browse/SPARK-33989
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.2.0
> Reporter: ulysses you
> Priority: Minor
>
> During analysis we may introduce the Cast if exists type cast implicitly.
> That makes assgined name unclear.
> Let's say we have a sql `select id == null` which id is int type, then the
> output field name will be `(id = CAST(null as int))`.
