数据:
aaa bbbb amount
111 222 333
222 222 444
111 333 555
111 222 777
结果:
aaa bbbb amount
111 222 333,777
222 222 444
111 333 555

amount 中,多个结果用 , 隔开。
------解决方案--------------------参考:
--生成测试数据
create table 表(部门 int,人员 varchar(20))
insert into 表 select 1, '张三 '
insert into 表 select 1, '李四 '
insert into 表 select 1, '王五 '
insert into 表 select 2, '赵六 '
insert into 表 select 2, '邓七 '
insert into 表 select 2, '刘八 '
go
--创建用户定义函数
create function f_str(@department int)
returns varchar(8000)
as
begin
declare @ret varchar(8000)
set @ret = ' '
select @ret = @ret+ ', '+人员 from 表 where 部门 = @department
set @ret = stuff(@ret,1,1, ' ')
return @ret
end
go
--执行
select 部门,人员=dbo.f_str(部门) from 表 group by 部门 order by 部门
go
--输出结果
/*
部门 人员
---- --------------
1 张三,李四,王五
2 赵六,邓七,刘八
*/
--删除测试数据
drop function f_str
drop table 表
go
------解决方案--------------------Create Table TEST
(aaa Int,
bbbb Int,
amount Int)
Insert TEST Select 111, 222, 333
Union All Select 222, 222, 444
Union All Select 111, 333, 555
Union All Select 111, 222, 777
GO
Create Function Getamount(@aaa Int, @bbbb Int)
Returns Varchar(8000)
As
Begin
Declare @S Varchar(8000)
Select @S = ' '
Select @S = @S + ', ' + Rtrim(amount) From TEST Where aaa = @aaa And bbbb = @bbbb
Select @S = Stuff(@S , 1, 1 , ' ')
Return @S
End
GO
Select
aaa,
bbbb,
dbo.Getamount(aaa, bbbb) As amount
From
TEST
Group By aaa, bbbb
GO
Drop Table TEST
Drop Function Getamount
--Result
/*
aaa bbbb amount
111 222 333,777
111 333 555
222 222 444
*/
------解决方案--------------------create table ta(aaa int, bbbb int, amount int)
insert ta
select 111, 222, 333 union all
select 222, 222, 444 union all
select 111, 333, 555 union all
select 111, 222, 777
create function test_f(@a int,@b int)
returns varchar(1000)
as
begin
declare @sql varchar(1000)
select @sql=isnull(@sql+ ', ', ' ')+rtrim(amount)
from ta where aaa=@a and bbbb=@b
return @sql
end
select distinct aaa,bbbb,dbo.test_f(aaa,bbbb)from ta
aaa bbbb
