Yingyu Wang updated CALCITE-5145:
---------------------------------
Summary: AssertionError: "Conversion to relational algebra failed to
preserve datatypes" when use derived column in Grouping Sets (was:

> + "group by grouping sets ((empno, derived_col),(empno))")
> .withConformance(SqlConformanceEnum.LENIENT).ok();
