I didn't notice your comment on slack until now. So currently Spark's Analyzer ensures that the `ResolveIntoTable` is fully resolved. [code](https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala#L1634-L1672) However, you are right that we don't do any semantics analysis on the plan currently. We should add it. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
