如何正确使用alter modify？

Question

我有 table 这样的：

+--------+---------------+------+-----+---------+----------------+
| Field  | Type          | Null | Key | Default | Extra          |
+--------+---------------+------+-----+---------+----------------+
| car_id | int(11)       | NO   | PRI | NULL    | auto_increment |
| vin    | varchar(20)   | YES  |     | NULL    |                |
| color  | varchar(10)   | YES  |     | NULL    |                |
| year   | varchar(4)    | YES  |     | NULL    |                |
| make   | varchar(10)   | YES  |     | NULL    |                |
| model  | varchar(15)   | YES  |     | NULL    |                |
| price  | decimal(10,3) | YES  |     | NULL    |                |
+--------+---------------+------+-----+---------+----------------+

和table的内容：

+--------+------+-------+------+----------+----------+-----------+
| car_id | vin  | color | year | make     | model    | price     |
+--------+------+-------+------+----------+----------+-----------+
|      1 | NULL | gray  | 1998 | Porsche  | Boxter   | 17992.540 |
|      2 | NULL | NULL  | 2000 | Jaguar   | XJ       | 15995.000 |
|      3 | NULL | red   | 2002 | Cadillac | Escalade | 40215.900 |
+--------+------+-------+------+----------+----------+-----------+

当我想（例如）将价格列放在颜色列之后时：

alter table car_table modify column price after color;

它说：

mysql> alter table car_table modify column price after color; ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'after color' at line 1

没用。怎么了？

Answer 1

使用下面的查询您错过了包含数据类型，

ALTER TABLE car_table MODIFY price decimal(10,3) AFTER color;
