Question

我有两张桌子。一个存储视频信息，另一个存储与该视频相关联的标签。他们共享共同字段vid_id。我正在尝试全文搜索两个表格的匹配。目标是如果两个表中都匹配，则从视频中收集具有该vid_id的所有字段。

问题是我的查询只是与Call to undefined method PDOConnectionFactory::errorInfo()崩溃了。它应返回一行，因为标记中有一个条目，其中name field = test。有人有主意吗？我一直在努力解决这个问题。

CREATE TABLE IF NOT EXISTS `tags` (
  `id` varchar(35) NOT NULL,
  `vid_id` varchar(35) NOT NULL,
  `name` varchar(45) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
  UNIQUE KEY `vid_id` (`vid_id`,`name`),
  FULLTEXT KEY `name` (`name`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

CREATE TABLE IF NOT EXISTS `video` (
  `timestamp` int(11) NOT NULL,
  `vid_id` varchar(32) NOT NULL,
  `file_name` varchar(32) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
  `uploader` varchar(55) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
  `title` varchar(30) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
  `subject_id` int(1) NOT NULL,
  FULLTEXT KEY `title` (`title`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

$sql = "SELECT video.*
  MATCH(video.title) AGAINST('?') as cscore, 
  MATCH(tags.name) AGAINST('?') as htscore
FROM video
LEFT JOIN tags ON video.vid_id=tags.vid_id
WHERE
  MATCH(video.title) AGAINST('?') OR
  MATCH(tags.name) AGAINST('?')
ORDER BY cscore DESC;";
$stmt4 = $conn->prepare($sql);
$result=$stmt4->execute(array('test','test','test','test')) or die(print_r($db->errorInfo(), true));

问题是您在SQL查询中SELECT video.*之后缺少逗号（，）。

工作示例：

SELECT video.*,
  MATCH(video.title) AGAINST('?') as cscore, 
  MATCH(tags.name) AGAINST('?') as htscore
FROM video
LEFT JOIN tags ON video.vid_id=tags.vid_id
WHERE
  MATCH(video.title) AGAINST('?') OR
  MATCH(tags.name) AGAINST('?')
ORDER BY cscore DESC;
