select部分很好，我可以运行它并获取结果，但是如果我将查询结果插入表中，则会引发“不是由表达式分组”异常，请参见下面的sql语句：
INSERT INTO RAWDATA_FACT
(
LINEITEMID
,CALENDARYEAR
,CALENDARQUARTER
,CALENDARMONTH
,DEPARTMENTID
,PRODUCTID
,DEALERID
,ACTUALVALUE
,TARGETVALUE
,AGGREGATION
,TODATE
,CREATEDATE
,BATCH_ID
)
select parentid
,calendaryear
,calendarquarter
,calendarmonth
,departmentid
,productid
,dealerid
,sum(case when unaryoperator = '-' then actualvalue * (-1)
when unaryoperator = '~' then actualvalue * 0
else actualvalue
end
) actualvalue
,sum(case when unaryoperator = '-' then targetvalue * (-1)
when unaryoperator = '~' then targetvalue * 0
else targetvalue
end
) targetvalue
