[jira] [Commented] (SPARK-36797) Union should resolve nested
columns as top-level columns
[ https://issues.apache.org/jira/browse/SPARK-36797?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17417069#comment-17417069 ]

> Union should resolve nested columns as top-level columns
> --------------------------------------------------------
>
> Key: SPARK-36797
> URL: https://issues.apache.org/jira/browse/SPARK-36797
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: L. C. Hsieh
> Priority: Major
>
> Union, by definition, resolves columns by position. Currently we only follow this behavior at top-level columns, but not nested columns.
> As we are making nested columns as first-class citizen, the nested-column-only limitation and the difference between top-level column and nested column do not make sense.
