ERROR 1292 (22007): Truncated incorrect DOUBLE value

表是这样
> desc prop;
+---------------+-------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+---------------+-------------+------+-----+---------+----------------+
| proid | int(10) | NO | PRI | NULL | auto_increment |
| cityid | int(2) | NO | | 0 | |
| content_basic | varchar(32) | NO | | | |
| content_other | text | YES | | NULL | |
| updated | int(10) | YES | | 0 | |
+---------------+-------------+------+-----+---------+----------------+

简单的一条query,故意写错
> update prop set content_basic='aa' and content_other='bb' where proid=17011445;
Query OK, 1 row affected, 1 warning (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 1

> show warnings;
+---------+------+----------------------------------------+
| Level | Code | Message |
+---------+------+----------------------------------------+
| Warning | 1292 | Truncated incorrect DOUBLE value: 'aa' |
+---------+------+----------------------------------------+
1 row in set (0.00 sec)

> select * from prop;
+----------+--------+---------------+---------------+------------+
| proid | cityid | content_basic | content_other | updated |
+----------+--------+---------------+---------------+------------+
| 17011445 | 11 | 0 | bb | 1377185448 |
+----------+--------+---------------+---------------+------------+

问题是就算被Truncated ,为什么content_basic字段会被changed 为0呢?想不通Mysql为啥这样设计,有的情况下会让人很闷。

有哪位大神可以帮忙解释下?
