如何按案例添加多个列？

Question

我的查询中有以下group by子句，它使用了一个case语句，但我也希望在该组中添加另一列：

        group by case @dateType

WHEN 'Daily' then i.overridedate
WHEN 'Weekly' then dateadd(day,-1*datepart(weekday,i.overridedate)+1,i.overridedate) 
WHEN 'Monthly' THEN DATEADD(day, -1*DATEpart(day,i.overridedate)+1, i.overridedate) 
WHEN 'Quarterly' THEN dateadd(mm,-3,DATEADD(qq, DATEDIFF(qq,0,i.overridedate )+1, 0)) END

如何通过？
