我有一张这样的表
+------------------+------------------+------+-----+-------------------+-----------------------------+
| Field | Type | Null | Key | Default | Extra |
+------------------+------------------+------+-----+-------------------+-----------------------------+
| id | int(10) unsigned | NO | PRI | NULL | auto_increment |
| user_id | int(10) unsigned | NO | | NULL | |
| arena_ids | json | NO | | NULL | |
| organization_id | int(10) unsigned | NO | MUL | NULL | |
| type | tinyint(4) | NO | | NULL | |
| registration_fee | double | YES | | NULL | |
| tax_group_id | int(10) unsigned | YES | MUL | NULL | |
| from_date | date | YES | | NULL | |
| to_date | date | YES | | NULL | |
| status | varchar(10) | YES | | NULL | |
| comments | varchar(100) | YES | | NULL | |
| created_at | datetime | NO | | CURRENT_TIMESTAMP | |
| updated_at | datetime | YES | | NULL | on update CURRENT_TIMESTAMP |
| deleted_at | datetime | YES | | NULL | |
+------------------+------------------+------+-----+-------------------+-----------------------------+
现在，在此表中，我需要再添加一列serial number
而且serial number会auto_increment，但在我的情况下，我需要增加serial_number，直到organization_id更改，如果organization_id更改，那么
serial_number从1开始。
`serial_number` `organization_id`
1 1
2 1
1 2
3 1
2 2
当我阅读文档时，我发现了一些像这样的例子，但我在这里我必须更新而不是创建
CREATE TABLE animals (
grp ENUM('fish','mammal','bird') NOT NULL,
id MEDIUMINT NOT NULL AUTO_INCREMENT,
name CHAR(30) NOT NULL,
PRIMARY KEY (grp,id)
)
+--------+----+---------+
| grp | id | name |
+--------+----+---------+
| fish | 1 | lax |
| mammal | 1 | dog |
| mammal | 2 | cat |
| mammal | 3 | whale |
| bird | 1 | penguin |
| bird | 2 | ostrich |
+--------+----+---------+
如何在更新查询中实现此功能。
