在触发器失败之前插入MySQL?

我在Windows XP上运行MySQL5.1.48,以下触发器测试不起作用:

-- Drop the old table
DROP TABLE IF EXISTS `ikasan01`.`ikasanwiretap`;

-- Create
CREATE TABLE  `ikasan01`.`ikasanwiretap` (
 `Id` bigint(20) NOT NULL AUTO_INCREMENT,
 `ModuleName` varchar(255) NOT NULL,
 `FlowName` varchar(255) NOT NULL,
 `ComponentName` varchar(255) NOT NULL,
 `EventId` varchar(255) NOT NULL,
 `PayloadId` varchar(255) NOT NULL,
 `PayloadContent` varchar(255) NOT NULL,
 `CreatedDateTime` datetime NOT NULL,
 `UpdatedDateTime` datetime NOT NULL,
 `Expiry` datetime NOT NULL,
 PRIMARY KEY (`Id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

-- In order to use now() as a DEFAULT value on a datetime column we
have to do it via a BEFORE INSERT TRIGGER
CREATE TRIGGER defaultUpdateDateTime
BEFORE INSERT ON ikasanwiretap FOR EACH ROW
SET NEW.UpdatedDateTime = now();

-- Test the trigger
insert into IkasanWiretap (ModuleName, FlowName, ComponentName,
EventId, PayloadId, PayloadContent, CreatedDateTime, Expiry) values
('3', '3', '3', '3', '3', '3', now(), now());

在我的触发器测试中,我仍然得到MySQL服务器,声明updatedDateTime没有默认值。

我已经尝试了所有我可以支配的事情,所以我想我会问你很多有用的事;)有什么想法吗?

干杯, 马蒂恩
