如何在ASC上對var char time列進行排序？

Question

我有一個名爲「order_details_child」，其描述表如下所示

mysql> desc order_details_child; 
+------------------+-------------+------+-----+---------+-------+ 
| Field   | Type  | Null | Key | Default | Extra | 
+------------------+-------------+------+-----+---------+-------+ 
| vendor_id  | varchar(50) | YES |  | NULL |  | 
| item_id   | varchar(20) | YES |  | NULL |  | 
| date_of_order | varchar(10) | YES |  | NULL |  | 
| time_of_order | varchar(10) | YES |  | NULL |  | 
+------------------+-------------+------+-----+---------+-------+ 
4 rows in set (0.01 sec) 

我有，我需要根據在上升爲了time_of_order以檢索記錄的要求？

order by time_of_order asc ?? (First ordered should be shown first) 

這是樣本記錄

+----------------------+-----------+---------+---------------+---------------+--------+ 
| order_child_id  | vendor_id | item_id | date_of_order | time_of_order | status | 
+----------------------+-----------+---------+---------------+---------------+--------+ 
| 1410070300301030O1O1 | 1   | 5  | 2014-10-07 | 15:10:30  | NEW | 
+----------------------+-----------+---------+---------------+---------------+--------+ 
1 row in set (0.00 sec) 

有誰請幫助我。

Answer 1

ORDER BY STR_TO_DATE（time_of_order， '％T'）ASC

％T = 24小時HH：mm：ss的 - 你的意思只是時間還是你的意思是日期嗎？
