------------------------------------

             Summary: leastRestrictiveStructuredType should reserve the 
StructKind instead of override it to FULLY_QUALIFIED
                 Key: CALCITE-5199
                 URL: https://issues.apache.org/jira/browse/CALCITE-5199
             Project: Calcite
          Issue Type: Bug
          Components: core
            Reporter: Wenrui Meng
            Assignee: Wenrui Meng


{code:java}
protected @Nullable RelDataType leastRestrictiveStructuredType(
    final List<RelDataType> types) {
  final RelDataType type0 = types.get(0); {code}
It ignores the struct kind from type0 but override it to FULLY_QUALIFIED. 


I think it's better to keep the original struct kind.
