mysql - 1292 截断不正确的 INTEGER 值

Question

我没看到什么？我不知道为什么会收到此错误。它甚至不应该要求一个整数。

MariaDB [ams]> describe server_current_status;
+----------+-------------+------+-----+---------+----------------+
| Field    | Type        | Null | Key | Default | Extra          |
+----------+-------------+------+-----+---------+----------------+
| id       | int(11)     | NO   | PRI | NULL    | auto_increment |
| serverid | varchar(20) | YES  |     | NULL    |                |
| status   | varchar(20) | YES  |     | NULL    |                |
| notify   | varchar(15) | YES  |     | NULL    |                |
| totime   | varchar(20) | YES  |     | NULL    |                |
| fromtime | varchar(20) | YES  |     | NULL    |                |

6 rows in set (0.00 sec)

MariaDB [ams]> UPDATE server_current_status SET notify = 'SOME' AND status = 'DOWN' WHERE serverid = '8';
Query OK, 0 rows affected, 2 warnings (0.04 sec)
Rows matched: 1  Changed: 0  Warnings: 2

MariaDB [ams]> show warnings;

Answer 1

notify = 'SOME' AND status = 'DOWN'

这是一个布尔表达式。引擎将其读取为

notify = ('SOME' AND (status = 'DOWN'))

因此引擎尝试转换'SOME'为布尔值（0在1MySQL/MariaDB 中）

你可能想要这个：

notify = 'SOME', status = 'DOWN'
