Question

我正在使用CakePHP，似乎无法翻译我在工作台上所做的SQL查询。这正是我想要做的，但我似乎无法使它发挥作用。

这是我对MySQL的查询：

select
    docs.id, docs.schoolId, schools.name, docs.datesubmitted, docs.status,
    uploads.iddocs,
    COUNT(*),
    COUNT(case uploads.staff_checked when 1 then 1 else null end)
FROM
    docs as docs, schools as schools,
    uploads as uploads
where
    docs.schoolId = schools.schoolId AND
    docs.id = uploads.iddocs AND
    docs.status ="Submitted"
group by
    docs.id;

我需要做的是组合三个表：文档，学校和上传。

这两项指标：COUNT(case when)和COUNT(*)表示审核的文档数量（COUNT(case when)）和需要审核的文档总数（COUNT(*)）。

到目前为止，MySQL正在展示我的需求。有人可以弄清楚如何在Cake中做到这一点吗？

尝试以下查询

$this->virtualFields = array(
    'count_case_uploads_staff_checked_when_1_then_1_else_null_end' => 'COUNT(case uploads.staff_checked when 1 then 1 else null end)',
    'count' => 'COUNT(*)',
);
$options = array(
    'fields' => array(
        'Doc.id',
        'Doc.schoolId',
        'schools.name',
        'Doc.datesubmitted',
        'Doc.status',
        'uploads.iddocs',
        'Doc.count_case_uploads_staff_checked_when_1_then_1_else_null_end',
        'Doc.count',
    ),
    'joins' => array(

        array(
        ),
    ),
    'conditions' => array(
        'Doc.schoolId = schools.schoolId',
        'Doc.id = uploads.iddocs',
        'Doc.status' => 'Submitted',
    ),
    'group' => array(
        'Doc.id',
    ),
);
$data = $this->find('all', $options);
