如何使用 「其中查詢」 CakePHP的3.X

Question

我必須使用MySQL查詢：

SELECT doctor_id FROM `appointments`where doctor_id in (SELECT doctor_id FROM doctor_staffs WHERE staff_id=11) 

結果：

doctor_id 
2 
4 
5 

，但我需要知道如何把它寫在CakePHP 3中

Answer 1

$this->loadModel('DoctorStaffs'); 
    $docTorStaff=$this->DoctorStaffs->find()->select(['doctor_id'])->where(['staff_id'=>11]); 
    $this->loadModel('Appointments'); 
    $appointments = $this->Appointments->find(); 
    $appointments=$appointments->where(['Appointments.doctor_id IN'=>$docTorStaff]);
