错误的日期时间值:'0000-00-00 00:00:00'

我最近接手了一个10年前创建的老项目。它使用MySQL 5.1。

除此之外，我需要将默认字符集从latin1更改为utf8。

举个例子，我有这样的表格:

  CREATE TABLE `users` (
    `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
    `first_name` varchar(45) CHARACTER SET latin1 COLLATE latin1_general_ci DEFAULT NULL,
    `last_name` varchar(45) CHARACTER SET latin1 COLLATE latin1_general_ci DEFAULT NULL,
    `username` varchar(127) CHARACTER SET latin1 COLLATE latin1_general_ci NOT NULL,
    `email` varchar(127) CHARACTER SET latin1 COLLATE latin1_general_ci NOT NULL,
    `pass` varchar(20) CHARACTER SET latin1 COLLATE latin1_general_ci NOT NULL,
    `active` char(1) CHARACTER SET latin1 COLLATE latin1_general_ci NOT NULL DEFAULT 'Y',
    `created` datetime NOT NULL,
    `last_login` datetime DEFAULT NULL,
    `author` varchar(1) CHARACTER SET latin1 COLLATE latin1_general_ci DEFAULT 'N',
    `locked_at` datetime DEFAULT NULL,
    `created_at` datetime DEFAULT NULL,
    `updated_at` datetime DEFAULT NULL,
    `ripple_token` varchar(36) CHARACTER SET latin1 COLLATE latin1_general_ci DEFAULT NULL,
    `ripple_token_expires` datetime DEFAULT '2014-10-31 08:03:55',
    `authentication_token` varchar(255) CHARACTER SET latin1 COLLATE latin1_general_ci DEFAULT NULL,
    PRIMARY KEY (`id`),
    UNIQUE KEY `index_users_on_reset_password_token` (`reset_password_token`),
    UNIQUE KEY `index_users_on_confirmation_token` (`confirmation_token`),
    UNIQUE KEY `index_users_on_unlock_token` (`unlock_token`),
    KEY `users_active` (`active`),
    KEY `users_username` (`username`),
    KEY `index_users_on_email` (`email`)
  ) ENGINE=InnoDB AUTO_INCREMENT=1677 DEFAULT CHARSET=utf8 CHECKSUM=1 DELAY_KEY_WRITE=1 ROW_FORMAT=DYNAMIC

我设置了自己的Mac来处理这个。没有考虑太多，我运行“brew install mysql”安装mysql 5.7。所以我有一些版本冲突。

我下载了这个数据库的副本并导入了它。

如果我试着像这样运行查询:

  ALTER TABLE users MODIFY first_name varchar(45) CHARACTER SET utf8 COLLATE utf8_general_ci    NOT NULL

我得到这个错误:

  ERROR 1292 (22007): Incorrect datetime value: '0000-00-00 00:00:00' for column 'created' at row 1

我想我可以用:

  ALTER TABLE users MODIFY created datetime  NULL DEFAULT '1970-01-01 00:00:00';
  Query OK, 0 rows affected (0.06 sec)
  Records: 0  Duplicates: 0  Warnings: 0

但我明白:

  ALTER TABLE users MODIFY first_name varchar(45) CHARACTER SET utf8 COLLATE utf8_general_ci    NOT NULL ;
  ERROR 1292 (22007): Incorrect datetime value: '0000-00-00 00:00:00' for column 'created' at row 1

我必须更新每个值吗?

当前回答

对于Symfony用户:添加一个默认的orm列，如下所示:

/**
 * @var DateTime $updatedAt
 *
 * @ORM\Column(name="updated_at", type="datetime", nullable=false, options={"default" : "CURRENT_TIMESTAMP"})
 */

其他回答

我还得到

SQLSTATE[22007]: Invalid datetime format: 1292错误的datetime 列值:'0000-00-00 00:00:00'

错误信息

通过将0000-00-00 00:00:00更改为1970-01-01 08:00:00来修复此问题

1970-01-01 08:00:00 Unix时间戳为0

使sql模式不严格

如果使用laravel，进入config->数据库，进入mysql设置，使严格模式为假

我在https://support.plesk.com/hc/en-us/articles/115000666509-How-to-change-the-SQL-mode-in-MySQL上找到了解决方案。我有这个:

mysql> show variables like 'sql_mode';
+---------------+-------------------------------------------------------------------------------------------------------------------------------------------+
| Variable_name | Value                                                                                                                                     |
+---------------+-------------------------------------------------------------------------------------------------------------------------------------------+
| sql_mode      | ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION |
+---------------+-------------------------------------------------------------------------------------------------------------------------------------------+
1 row in set, 1 warning (0.01 sec)

注意上面结果中的NO_ZERO_IN_DATE,NO_ZERO_DATE。我通过这样做去掉了它:

mysql> SET sql_mode = 'ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
Query OK, 0 rows affected, 1 warning (0.00 sec)

然后我有了这个:

mysql> show variables like 'sql_mode';
+---------------+--------------------------------------------------------------------------------------------------------------+
| Variable_name | Value                                                                                                        |
+---------------+--------------------------------------------------------------------------------------------------------------+
| sql_mode      | ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION |
+---------------+--------------------------------------------------------------------------------------------------------------+
1 row in set, 1 warning (0.01 sec)

在此之后，我可以成功地使用ALTER TABLE并更改我的表。

如果手动输入数据，可以考虑删除时间戳(6)上的值和零。000000，这样它就变成了TIMESTAMP。这对我来说很有效。
