如何在较低版本的SQL上修复Magento时间戳记问题

Question

如何在较低版本的SQL上修复Magento时间戳记问题？

我已按照

进行了以下修复

`modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT 'User Modified Time'

到

`modified` timestamp NOT NULL DEFAULT 0 COMMENT 'User Modified Time'

现在想知道如何解决

1293-错误的表定义； DEFAULT或ON UPDATE子句中只能有一个带有CURRENT_TIMESTAMP的TIMESTAMP列

DROP TABLE IF EXISTS `integration`;
CREATE TABLE IF NOT EXISTS `integration` (
  `integration_id` int(10) UNSIGNED NOT NULL AUTO_INCREMENT COMMENT 'Integration ID',
  `name` varchar(255) NOT NULL COMMENT 'Integration name is displayed in the admin interface',
  `email` varchar(255) NOT NULL COMMENT 'Email address of the contact person',
  `endpoint` varchar(255) DEFAULT NULL COMMENT 'Endpoint for posting consumer credentials',
  `status` smallint(5) UNSIGNED NOT NULL COMMENT 'Integration status',
  `consumer_id` int(10) UNSIGNED DEFAULT NULL COMMENT 'Oauth consumer',
  `created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT 'Creation Time',
  `updated_at` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00' ON UPDATE CURRENT_TIMESTAMP COMMENT 'Update Time',
  `setup_type` smallint(5) UNSIGNED NOT NULL DEFAULT '0' COMMENT 'Integration type - manual or config file',
  `identity_link_url` varchar(255) DEFAULT NULL COMMENT 'Identity linking Url',
  PRIMARY KEY (`integration_id`),
  UNIQUE KEY `INTEGRATION_NAME` (`name`),
  UNIQUE KEY `INTEGRATION_CONSUMER_ID` (`consumer_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='integration';

{updated_at时间戳记非空默认值'0000-00-00 00:00:00'ON UPDATE CURRENT_TIMESTAMP COMMENT'Update Time'，
