php - 如何在cakephp中加入

Question

我尝试获取学生的结果(最后插入)。

我可以轻松地使用 mysql 查询来获取记录。

 SELECT student.first_name,student.last_name,result.* 
    FROM result 
    join student 
        on student.student_id=result.student_id 
 WHERE result.id IN (
            SELECT MAX(result.id) FROM result GROUP BY result.student_id
        )

我尝试将其转换为 cake-php，就像这样使用分页

$this->paginate = array(
    'fields' => array(
        'Student.first_name',
        'Student.last_name',
        'Result.*',
    ),
    'joins' => array(

        array(
            'conditions' => array(
                'Student.student_id = Result.student_id',
            ),
            'table' => 'student',
            'alias' => 'Student',
            'type' => 'join',
        ),
    ),
    'conditions' => array(
        'Result.id' => array(
        ),
    ),
    'limit'=>10,
    'contain' => array(
        'Student',
    ),
);
$data = $this->paginate('Result');

请尝试这个

$this->paginate = array(
    'fields' => array(
        'Student.first_name',
        'Student.last_name',
        'Result.*',
    ),
    'joins' => array(
        array(
            'conditions' => array(
                'Student.student_id = Result.student_id',
            ),
            'table' => 'student',
            'alias' => 'Student',
            'type' => 'join',
        ),
    ),
    'conditions' => array(
        'Result.id IN ( SELECT MAX(result.id) FROM result GROUP BY result.student_id )
    ),
    'limit'=>10
);
$data = $this->paginate('Result');
