请教统计的SQL写法
数据表A
id type area num1 num2 num3
11 A AA 3 8 5
13 B BB 1 5 1
14 B CC 3 4 4
15 A AA 3 3 5
16 C CC 2 4 8
17 C DD 3 1 6
18 D DD 5 4 7
19 D BB 3 4 3


要的结果是这样的
id type area num1 num2 num3
11 A AA 3 8 5
13 B BB 1 5 1
14 B CC 3 4 4
15 A AA 3 3 5
16 C CC 2 4 8
17 C DD 3 1 6
18 D DD 5 4 7
19 D BB 3 4 3
Total 23 33 39


求大神指教,我用rollup不行啊,rollup会对每种类型都分开统计,而我不需要类型分开

谢谢

SQL code

select id,type,area,num1,num2,num3 
from 你的表
union 
select null,null,null,sum(num1),sum(num2),sum(num3)
from 你的表

------解决方案--------------------
如果要用rollup 要添加子查询过滤条件了 一步完成不了吧 空值可以自己转换成合计

SQL code

with t1 as
(
     select 11 c1,'a' c2,'aa' c3,3 c4,8 c5,5 c6 from dual
     union all
     select 13 c1,'b' c2,'bb' c3,1 c4,5 c5,1 c6 from dual
     union all
     select 14 c1,'b' c2,'cc' c3,3 c4,4 c5,4 c6 from dual
)

select *
from 
(
  select c1,c2,c3,sum(c4) c4,sum(c5) c5,sum(c6) c6 
  from t1
  group by rollup(c1,c2,c3)
) t1
where (c2 is not null and c3 is not null) or c1 is null


     c1    c2    c3    c4    c5    c6
------------------------------------------------------
1    11    a    aa    3    8    5
2    13    b    bb    1    5    1
3    14    b    cc    3    4    4
4                7    17    10

SQL code
WITH CTE AS
(
SELECT 11 id,'A' type,'AA' area,3 num1,8 num2,5 num3 FROM DUAL
UNION ALL
SELECT 13, 'B', 'BB', 1, 5, 1 FROM DUAL UNION ALL
SELECT 14, 'B', 'CC', 3, 4, 4 FROM DUAL UNION ALL
SELECT 15, 'A', 'AA', 3, 3, 5 FROM DUAL UNION ALL
SELECT 16, 'C', 'CC', 2, 4, 8 FROM DUAL UNION ALL
SELECT 17, 'C', 'DD', 3, 1, 6 FROM DUAL UNION ALL
SELECT 18, 'D', 'DD', 5, 4, 7 FROM DUAL UNION ALL
SELECT 19, 'D', 'BB', 3, 4, 3 FROM DUAL 
)
SELECT N.ID,
       NVL(N.type,M.TYPE) TYPE,AREA,
       NVL(NUM1,M.A) NUM1,
       NVL(NUM2,M.B) NUM2,
      NVL(NUM3,M.C) NUM3 
   FROM CTE N FULL JOIN 
      (SELECT 'TOTAL' TYPE, SUM(NUM1) A,SUM(NUM2) B,SUM(NUM3) C
             FROM CTE) M
    ON N.TYPE=M.TYPE
结果如下:
19    D    BB    3    4    3
18    D    DD    5    4    7
17    C    DD    3    1    6
16    C    CC    2    4    8
15    A    AA    3    3    5
14    B    CC    3    4    4
13    B    BB    1    5    1
11    A    AA    3    8    5
    TOTAL        23    33    39
