Mysql where子句的DQL问题

你好，我有这个条款：

SELECT y,
CASE WHEN (v IS NULL) THEN 0 ELSE SUM(v.viewCount) END AS HIDDEN sumviewcount
FROM YTScraperBundle:YouTubeVideo y
LEFT JOIN y.allViews v WITH v.firstFetch BETWEEN :fromDate AND :toDate
GROUP BY y ORDER BY sumviewcount DESC

这非常好，但当我尝试添加WHERE子句时，例如：

SELECT y,
CASE WHEN (v IS NULL) THEN 0 ELSE SUM(v.viewCount) END AS HIDDEN sumviewcount
FROM YTScraperBundle:YouTubeVideo y
LEFT JOIN y.allViews v WITH v.firstFetch BETWEEN :fromDate AND :toDate
WHERE y.name LIKE :videoName
GROUP BY y ORDER BY sumviewcount DESC

videoName的绑定方式如下：

$query->setParameter('videoName', "%" . $searchData['searchValue'] . "%");

所以这不是问题所在，无论如何，我得到的错误是：

Error: Expected end of string, got 'y'","class":"Doctrine\\ORM\\Query\\QueryException

您是否为搜索值尝试了不同的值？

隐藏的sumviewcount

应该是一个单词或用引号括起来，即
