[讨论]问个SQL语句,不使用存储过程得:(

某数据表(表名:access)中有如下字段:

xxx_id
  1
  1
  2
  2
  2
  1
  3
  1
  2
  3
  3
  3
  3
  1
  1

要是按照XXX_id进行分组,同时,按照每组中xxx_id的个数进行排序(desc)

DBMS:mysql

要求不使用存储过程实现

咋办???

明白
谢谢2位了

晕，检柏真快~~~

mysql 测试
create table tt(
id int
);

insert .....

mysql> select * from tt;
+------+
| id   |
+------+
|    1 |
|    1 |
|    1 |
|    2 |
|    2 |
|    3 |
|    3 |
|    4 |
|    4 |
|    4 |
+------+
10 rows in set (0.00 sec)

结果：
mysql> select id,count(id) as cid from tt group by id order by cid desc;
+------+-----+
| id   | cid |
+------+-----+
|    1 |   3 |
|    4 |   3 |
|    2 |   2 |
|    3 |   2 |
+------+-----+
4 rows in set (0.00 sec)

不知道是不是楼主想要的~~

select count(xxx_id) from table goup by xxx_id order by count(xxx_id) desc
或
select count(xxx_id) from table goup by xxx_id order by 1 desc
