Question

我想查询＆＃34; 更新类别c SET c.display =！c.display ＆＃34; 但我得到了例外。

我的代码：

$qb = $entityManager->createQueryBuilder();
$q = $qb->update('Category', 'c')
        ->set('c.display', '!c.display')
        ->getQuery();

$p = $q->execute();

我收到异常

如果您使用的数据库中布尔值存储为1或0，则可以尝试使用

$q = $qb->update('Category', 'c')
        ->set('c.display', '1 - c.display')
        ->getQuery();
