怎么写，求语句
[解决办法]
with temp as (select '篮球' name,20 price,2 num,1 type from dualunion allselect '足球' name,10 price,3 num,1 type from dualunion allselect '羽毛球' name,5 price,10 num,1 type from dualunion allselect '白衣' name,28 price,1 num,2 type from dualunion allselect '红衣' name,32 price,3 num,2 type from dualunion allselect '黑衣' name,30 price,1 num,2 type from dual)select type,name,sum(price*num) totalprice from temp group by rollup(type,name) order by type
[解决办法]
这样可以么？
create table t1 (name varchar2(10), price number(10,2), num number(5), type varchar2(5));insert into t1 values ('篮球', 20,2,1);insert into t1 values ('足球', 10,3,1);insert into t1 values ('羽毛球', 5,10,1);insert into t1 values ('白衣', 28,1,2);insert into t1 values ('红衣', 32,3,2); insert into t1 values ('黑衣', 30,1,2);commit;select type,nvl(name,'合计') name,sum(price*num) t_pricefrom t1group by rollup(type,name) type name t_price-----------------------------------1 1 篮球 402 1 足球 303 1 羽毛球 504 1 合计 1205 2 白衣 286 2 黑衣 307 2 红衣 968 2 合计 1549 合计 274

--name price num type
with t as (
select '篮球' as fname, 20 as price, 2 as num, 1 as ftype from dual
union all
select '足球', 10, 3, 1 from dual
union all
select '羽毛球', 5, 10, 1 from dual
union all
select '白衣', 28, 1, 2 from dual
union all
select '红衣', 32, 3, 2 from dual
union all
select '黑衣', 30, 1, 2 from dual
)
select ftype,nvl(fname,'total(' || case when grouping(ftype)=0 then to_char(ftype) else 'all' end || '):') as fname,sum(price) as totalprice from t
group by rollup(ftype,fname)
--结果
