我有一张post
桌子,它的架构是这样的:
CREATE TABLE IF NOT EXISTS `post` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`user_id` bigint(20) DEFAULT NULL,
`site_id` bigint(20) DEFAULT NULL,
`parent_id` bigint(20) DEFAULT NULL,
`title` longtext COLLATE utf8_turkish_ci NOT NULL,
`status` varchar(20) COLLATE utf8_turkish_ci NOT NULL,
PRIMARY KEY (`id`),
KEY `IDX_5A8A6C8DA76ED395` (`user_id`),
KEY `IDX_5A8A6C8DF6BD1646` (`site_id`),
KEY `IDX_5A8A6C8D727ACA70` (`parent_id`),
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_turkish_ci AUTO_INCREMENT=16620 ;
我正在使用这个 DQL 来获取一个帖子,它是孩子:
$post = $this->_diContainer->wordy_app_doctrine->fetch(
"SELECT p,c FROM Wordy\Entity\Post p LEFT JOIN p.children c WHERE p.site = :site AND p.id = :id AND p.language = :language AND p.status != 'trashed' AND c.status != 'trashed' ORDER BY c.title",
array(
'params' => array(
'id' => $id,
'site' => $this->_currentSite['id'],
'language' => $this->_currentLanguage->code,
)
)
);
我想做的是:获取一个帖子和所有的孩子。标准是,不包括已删除的帖子或已删除的孩子。
但是当我用一个甚至没有孩子的帖子运行这个查询时,返回的结果集是空的。
当我c.status != 'trashed'
从查询中删除部分时,一切正常,但我也会收到垃圾帖子。
提前致谢。
编辑:这是给定 DQL 的 SQL 输出:
SELECT p0_.id AS id0, p0_.title AS title5, p0_.status AS status8, p0_.parent_id AS parent_id9, p1_.id AS id15, p1_.title AS title20, p1_.status AS status23, p1_.parent_id AS parent_id24 FROM post p0_ LEFT JOIN post p1_ ON p0_.id = p1_.parent_id WHERE p0_.site_id = ? AND p0_.id = ? AND p0_.language = ? AND p0_.status <> 'trashed' ORDER BY p1_.title ASC
