求一条SQL语句,关于分组排列显示
求一条SQL语句,高手请进,关于分组排列显示。
数据库字段如下:
表A
ID NAME SORT
1 A 01
2 B 02
3 C 03
4 D 01
5 E 02
6 F 03
表 B
id sortname
01 AA
02 BB
03 CC
其中SORT是种类 是从表B中插入得到的
现在我想显示的是
SORT:AA
1 A
2 D
SORT:BB
1 B
2 E
SORT:CC
1 C
2 F
也就是把种类分组然后分别遍历出来。最好能用最简单的SQL语句实现。请高手帮忙。
------解决方案--------------------
left join 取出值,构造成
$result['AA'] = array('A','D');
$result['BB'] = array('B','E');
...
这样的数组,显示不就轻而易举了吗.
------解决方案--------------------
- SQL code
select A.id,A.name,C.sortname from A,(select id,sortname from B) C where A.sort=C.id group by C.sortname,A,name,A,id order by C.id <div class="clear"> </div>
