Question

我有一个名为'order_details_child'的表，其描述如下所示

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)

我有一个要求，我需要根据升序顺序中的 time_of_order 来检索记录？

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

这是样本记录

+----------------------+-----------+---------+---------------+---------------+--------+
| 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)

请有人帮帮我。

Answer 1

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

％T = 24小时hh：mm：ss - 您的意思是时间还是指日期？

请参阅http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_date-format

如何对ASC的var char时间列进行排序？
