循环问题－－HELP
求教：
表1：
db_1

fid
fup
name
---------------
表2：
db2

fid
subject
---------------
fid（表db_1）＝fid（表db_2）
--------------------------------
我是想循环列出表1中 fup＝0 的name以及跟name相关的subject。

|
| name1 | name2 | name3 | name4
|subject subject subject subject
|subject subject subject subject
|subject subject subject subject
|subject subject subject subject
|subject subject subject subject
|subject subject subject subject
|

------解决方案--------------------
select db_1.name,db_2.subject from db_1,db_2 where db_1.fid=db_2.fid and db_1.fup=0 
 group by db_1.name,db_2.subject
