我在插入触发器后遇到问题。当我在表中插入数据时,它应该自动更新日期,它应该是当前日期。但是当我执行以下查询时,它在我的表中无法正常工作。首先我创建了一个表:
DROP TABLE IF EXISTS `ignite`.`products`;
CREATE TABLE `ignite`.`products`(
`products_id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`products_model` varchar(30) NOT NULL,
`model_hash` bigint(20) unsigned NOT NULL,
`Product_name` varchar(45) NOT NULL,
`created` datetime NOT NULL,
PRIMARY KEY (`products_id`)
) ENGINE=MyISAM AUTO_INCREMENT=977 DEFAULT CHARSET=latin1;
然后我创建了这个触发器:
use ignite;
CREATE TRIGGER created_date BEFORE INSERT ON products
FOR EACH ROW
SET NEW.created = NOW();
但是当我在这个表中插入数据时:
use ignite;
INSERT INTO products
(products_id, products_model, model_hash, Product_name)
values
(123, "456645", 457567, "awetert");
这显示以下错误:
field 'created' does not have default value. error-1364
