mysql - symfony2/doctrine2 dql 其中字段不正确

Question

我在检查带有“不是真的”子句的 bool 字段时遇到了麻烦我收到此错误:

("[Syntax Error] line 0, col 510: Error: Expected =, <, <=, <>, >, >=, !=, got 'IS'")

查询是用 dql 构建的。所以在代码中我像这样添加了

$dql .= " AND p.archived IS NOT TRUE ";

执行的查询:

SELECT COUNT(p.id)
FROM Sandbox\WebsiteBundle\Entity\Pages\OfferPage p
INNER JOIN Kunstmaan\NodeBundle\Entity\NodeVersion nv WITH nv.refId = p.id
INNER JOIN Kunstmaan\NodeBundle\Entity\NodeTranslation nt WITH nt.publicNodeVersion = nv.id and nt.id = nv.nodeTranslation
INNER JOIN Kunstmaan\NodeBundle\Entity\Node n WITH n.id = nt.node WHERE n.deleted = 0
AND n.hiddenFromNav = 0
AND n.refEntityName = 'Sandbox\WebsiteBundle\Entity\Pages\OfferPage'
AND nt.online = 1 AND nt.lang = :lang AND p.archived IS NOT TRUE AND p.expirationDate >= :date ORDER BY p.price ASC

Answer 1

通常当你在 Doctrine 中配置了一个 bool 值时，你有一个带有 0 或 1 的整数字段。检查值是 0 还是 1 会容易得多。

$dql .= " AND p.archived = 0";

或其他解决方案:

$dql .= " AND p.archived = false";

或者如果您检查为 null

$dql .= " AND p.archived is null";

当您查看页面时，您会看到一些表情。 IS 不能在该上下文中使用。
