Group by fails on view with Columnstore engine

Hi,

The attached SQL shows a select statement that only produces the following error when executed on a view of a table using the columnstore engine:

ERROR 1815 (HY000) at line 23: Internal error: IDB-2021: 'dt' is not in GROUP BY clause. All non-aggregate columns in the SELECT and ORDER BY clause must be in
cluded in the GROUP BY clause.

I came across this while using Metabase as this is how it produces aggregate queries.
