Why I got an error when running a ??select * ?? query?
The cube only has aggregated data, so all your queries should be aggregated
queries (??GROUP BY??). You can use a SQL with all dimensions be grouped to get
them as close as the detailed result, but that is not the raw data.
In order to be connected from some BI tools, Kylin tries to answer ??select *??
query but please aware the result might not be expected. Please make sure each
query to Kylin is aggregated.
