Question

我的应用程序需要在CakePHP中重新编码。

我通过子选择进行了以下选择：

        SELECT COUNT(*) AS item1,
            (SELECT COUNT(*) FROM portal_members) AS item3, 
            (SELECT COUNT(*) FROM portal_reviews) AS item3, 
            (SELECT COUNT(*) FROM portal_downloads) AS item4
        FROM portal_articles 
        WHERE 1 = 1

任何人都知道如何使用CakePHP find（$ type，$ params）创建该查询？

Answer 1

如果这是您的确切查询，我建议您分四次通过。

$item1 = $this->PortalArticle->find('count');
$item2 = $this->PortalReview->find('count'); // etc..

运行可能需要更长时间，但您的意图更清晰，代码更清晰。

Answer 2

请尝试此代码

$this->loadModel('PortalArticle');
$db = $this->PortalArticle->getDataSource();
$a = $db->fetchAll(
    ' SELECT COUNT(*) AS item1,
    (SELECT COUNT(*) FROM portal_members) AS item3, 
    (SELECT COUNT(*) FROM portal_reviews) AS item3, 
    (SELECT COUNT(*) FROM portal_downloads) AS item4
FROM portal_articles 
WHERE 1 = 1'
);
