This feels like a bit of a blind spot in MySQL to me. [The docs say](https://dev.mysql.com/doc/refman/5.7/en/group-by-handling.html) that since 5.7.5 MySQL has detected functional dependence of expressions on the grouped columns when ONLY_FULL_GROUP_BY is _enabled_. Yet the null ordering expression `foo is null` generated by Calcite is certainly funtionally dependent on `foo` and it still gets rejected. -- This is an automated message from the Apache Git Service.
