关于列转行

很多情况下会遇到这种情况:

 

表里的数据是:

  id      name
3200    01
3200    02
3200    03
3200    04

 

需要的结果是:

 

id         name

3200   01,02,03,04

 

 

其实现脚本是:

 

1 、在10g下:

with t as (

select 3200 id , 01 name from dual
union all

select 3200 id , 02 name from dual
union all

select 3200 id , 03 name from dual
union all

select 3200 id , 04 name from dual
 

)

 

 

select id,wmsys.wm_concat(name)   name from t group by id;
 

 

2、在9i下

 select * from t
 

select id,  substr(max(sys_connect_by_path( name,',')),2)  name
from (select t.*,row_number()over(order by  name) rn from t )
  group by id
  start with rn=1
connect by rn-1=prior rn
