@john-bodley AdhocMetrics are always created from the datasource columns so I think from a user's perspective, it is expected that the aggregation should apply only to known columns of the underlying table (be it virtual or physical)---not another ad-hoc metric or derived column. A table name prefix will be totally transparent to the UI and users would not need to do anything extra. It is needed to create a concise & _correct_ SQL query because in this case we obviously didn't give SQLAlchemy enough hints to generate unambiguous SQL queries for all data engines. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
