表1结构
xh dwmc zgbm（主管部门）
1 单位1 A
2 单位2 A
3 单位3 B
4 单位4 B
5 单位5 B
6 单位6 C
表2
dwmc je
单位1 1
单位2 2
单位3 3
单位4 4
单位5 5
单位6 6
想要这种结果,并插入数据库中
mc je
A 3
单位1 1
单位2 2
B 11
单位3 3
单位4 4
单位5 5
c 6
单位6 6
------最佳解决方案--------------------
if object_id('[A]') is not null
drop table [A]
go
create table [A]([xh] int,[dwmc] nvarchar(5),[zgbm] varchar(1))
insert [A]
select 1,N'单位1','A' union all
select 2,N'单位2','A' union all
select 3,N'单位3','B' union all
select 4,N'单位4','B' union all
select 5,N'单位5','B' union all
select 6,N'单位6','C'--> 测试数据：[B]
if object_id('[B]') is not null
drop table [B]
go
create table [B]([dwmc] nvarchar(5),[je] int)
insert [B]
select N'单位1',1 union all
select N'单位2',2 union all
select N'单位3',3 union all
select N'单位4',4 union all
select N'单位5',5 union all
select N'单位6',6
go
select mc,je from
(select a.zgbm as mc,sum(b.je) as je,1 as no,a.zgbm
from A a join B b on a.dwmc=b.dwmc group by zgbm
union all
select b.dwmc,b.je,2,a.zgbm
from A a join B b on a.dwmc=b.dwmc) t
order by zgbm,no
/*
mc je
----- -----------
