francis0407 commented on issue #23783: [SPARK-26854][SQL] Support ANY/SOME subquery URL: https://github.com/apache/spark/pull/23783#issuecomment-466881768 I'm not sure where to throw the analysis exception, how about this: ``` scala case class AnySubquery(...) { if (values.size > 1) { throw new AnalysisException( "ANY/SOME predicate doesn't support multi-column currently", origin.line, origin.startPosition) } } ``` Besides, should I remove those redundant test cases? I'll add more tests that focus on the comparison operators, especially with 'null'.
