我正在做一个Yii项目.如何使用MySQL的ON DUPLICATE功能( http:在Yii模型上执行save()时//dev.mysql/doc/refman/5.0/zh-CN/insert-on-duplicate.html )?
I am working on a Yii project. How can I use the ON DUPLICATE feature of MySQL ( dev.mysql/doc/refman/5.0/en/insert-on-duplicate.html ) when doing a save() on a Yii model?
我的MySQL如下:
CREATE TABLE `ck_space_calendar_cache` ( `space_id` int(11) NOT NULL, `day` date NOT NULL, `available` tinyint(1) unsigned NOT NULL DEFAULT '0', `price` decimal(12,2) DEFAULT NULL, `offer` varchar(45) DEFAULT NULL, `presale_date` date DEFAULT NULL, `presale_price` decimal(12,2) DEFAULT NULL, `value_x` int(11) DEFAULT NULL, `value_y` int(11) DEFAULT NULL, PRIMARY KEY (`space_id`,`day`), KEY `space` (`space_id`), CONSTRAINT `space` FOREIGN KEY (`space_id`) REFERENCES `ck_space` (`id`) ON DELETE CASCADE ON UPDATE NO ACTION ) ENGINE=InnoDB DEFAULT CHARSET=utf8;我的PHP如下:
$cache = new SpaceCalendarCache(); $cache->attributes = $day; //Some array with attributes $cache->save();如果我的主键(sapce_id,天)中有重复项,我不想让它抱怨,我只希望它使用最新数据进行更新.
If there is a duplicate in my primary key (sapce_id,day), I don't want it to complain, I just want it to update with the latest data.
我知道如何在原始SQL中执行此操作,我只是想知道是否存在一种干净的Yii方法.
I know how to do it in raw SQL, I was just wondering if there is a clean Yii way to do it.
推荐答案我覆盖了beforeValidate(),在该处检查是否存在重复项.如果有,我设置$this->setIsNewRecord(false);
I overrode beforeValidate() where I checked if a duplicate exists. If one does, I set $this->setIsNewRecord(false);
似乎可以正常工作.不确定性能如何.
Seems to work. Not sure how performant it is.
