更新之前。在組（0.00秒）

更新記錄

mysql> select parcel_id,type, status ,accepted_at,accepted_user,submitted_at,submitted_user, updated_at from parcel_deliveries; 
+---------------+------+--------+---------------------+---------------+---------------------+----------------+---------------------+ 
| parcel_id  | type | status | accepted_at   | accepted_user | submitted_at  | submitted_user | updated_at   | 
+---------------+------+--------+---------------------+---------------+---------------------+----------------+---------------------+ 
| RI013502995TH | 1 |  1 | 2015-09-29 15:01:44 | hnong   | 2015-09-29 17:19:56 | hnong   | 2015-09-30 16:50:11 | 
| EN064142823TH | 1 |  1 | 2015-10-02 16:17:39 | hnong   | 2015-10-02 16:48:24 | hnong   | 2015-10-02 17:12:39 | 
| EN064142823TH | 2 |  1 | 2015-10-02 16:39:43 | hnong1  | 2015-10-02 16:48:24 | hnong   | 2015-10-02 17:12:39 | 
+---------------+------+--------+---------------------+---------------+---------------------+----------------+---------------------+ 

3行，我打算只更新1行（parcel_id = EN064142823TH，類型= 2）

$a = App\Parcel_delivery::where('parcel_id', 'EN064142823TH') 
->where('type', '=', 2) 
->where('postal_code', '10170')                     
->orderBy('created_at', 'desc')->first(); 

=> App\Parcel_delivery {#829 
    parcel_id: "EN064142823TH", 
    type: 2, 
    status: 1, 
    accepted_at: "2015-10-02 16:39:43", 
    accepted_user: "hnong1", 
    submitted_at: "2015-10-02 16:48:24", 
    submitted_user: "hnong", 
    destination_id: null, 
    person_type: null, 
    signature: null, 
    comment: "", 
    run_no: null, 
    } 
>>> $a->status = 5; 
=> 5 
>>> $a->save();                        => true 

後更新。在集（0.00秒）

+---------------+------+--------+---------------------+---------------+---------------------+----------------+---------------------+

+---------------+------+--------+---------------------+---------------+---------------------+----------------+---------------------+ 

3行，我不知道爲什麼另一個紀錄是更新還（parcel_id = EN064142823TH，類型= 1）。

請建議。非常感謝你。

您的表格缺少一個唯一的主鍵，因此雄辯不能區分一個記錄與另一個記錄，因此無法應用更新。將一個autoincrement id主鍵字段添加到您的表中，我認爲這個問題將得到解決。
