Question

我想知道MySQL是否有可能通过包含名字和姓氏的名称列来命令我的结果。

例如：

“title”：Albert CATERSON - Barabara ABELS - Chris WASPINK

SQL .. 
ORDER BY title

结果将是：

Albert CATERSON - Barabara ABELS - Chris WASPINK

但我想按姓氏排序我的结果：

ABELS Barabara - CATERSON Albert - WASPINK Chris

你知道在mysql中是否可以这样做？谢谢。

Answer 1

试试这个

DROP TABLE IF EXISTS OrderBySurname;
Query OK, 0 rows affected, 1 warning (0.01 sec)


CREATE TABLE OrderBySurname(id INT, title VARCHAR(255));
Query OK, 0 rows affected (0.26 sec)


INSERT INTO `OrderBySurname` (`id`, `title`) VALUES ('1','Albert CATERSON'),('2', 'Barabara ABELS'),('3', 'Chris WASPINK');
Query OK, 3 rows affected (0.01 sec)
Records: 3  Duplicates: 0  Warnings: 0


SELECT title , SUBSTRING_INDEX(title, ' ', -1) AS sur_name FROM OrderBySurname ORDER BY sur_name;
+-----------------+----------+
| title           | sur_name |
+-----------------+----------+
| Barabara ABELS  | ABELS    |
| Albert CATERSON | CATERSON |
| Chris WASPINK   | WASPINK  |
+-----------------+----------+
3 rows in set (0.00 sec)


SELECT CONCAT(SUBSTRING_INDEX(title, ' ', -1),' ',SUBSTRING_INDEX(title, ' ', 1)) FROM OrderBySurname ORDER BY SUBSTRING_INDEX(title, ' ', -1);
+----------------------------------------------------------------------------+
| CONCAT(SUBSTRING_INDEX(title, ' ', -1),' ',SUBSTRING_INDEX(title, ' ', 1)) |
+----------------------------------------------------------------------------+
| ABELS Barabara                                                             |
| CATERSON Albert                                                            |
| WASPINK Chris                                                              |
+----------------------------------------------------------------------------+
3 rows in set (0.00 sec)

Answer 2

如果您想通过姓氏订购，则需要使用SUBSTRING_INDEX：

ORDER BY SUBSTRING_INDEX(title, ' ', -1);

但是，如果你想要姓氏首先出现，你需要这样的东西：
SELECT CONCAT(SUBSTRING_INDEX(title, ' ', -1), ' ', SUBSTRING_INDEX(title, ' ', 1))

按包含名称和姓氏的字段对结果进行排序
