首先是一个特定的 id，然后是 desc 顺序的所有 id

Question

我首先需要获取一个特定的 id，然后，所有 id 都按降序排列。这就是我所做的，但是当我取消注释该订单行时，它将不起作用，

$result = $this->Practicetestanswers->find('all',
    ['contain' => ['Practicetestquestions' =>
        ['Practicetestconceptassignment' => ['Practicetestconcept', 'Practicetest']
        ]]])
    ->where(['Practicetestanswers.user_id' => $student_id,
        'Practicetestquestions.is_active' => 'y',
        'Practicetest.is_active' => 'y'
    ])
    ->select([
        'id' => 'Practicetest.id',
        'test_code' => 'Practicetest.test_code',
        'test_title' => 'Practicetest.test_title',
        'time_taken' => 'SUM(Practicetestanswers.time_taken)',
    ])
    ->group('Practicetest.id')
  //    ->order(["FIELD(Practicetest.id, '228')" => 'DESC'])   //need like this
        ->order(["Practicetest.id" => 'DESC'])
        ->hydrate(false)
        ->toArray();

Answer 1

只需按条件将此行替换为您的订单

->order(['FIELD(Practicetest.id, "228")'=> 'DESC', "Practicetest.id" => 'DESC' ])
