Mysql SQL查询以获取文本中的最后一个词

Question

我的数据库中有类似于下面的文本

this is my car
how are you,doing
how is your)health
this is not(working

当我查询数据库时，我应该从这篇文章中得到最后的话。在这个例子中

1st row should return "car"
2nd row should return "doing"
3rd row should return "health"
4th row should return "working"

关于如何获得这个的任何想法？

谢谢你的帮助

这是一个例子：

create table lastword (
id int not null auto_increment primary key,
mytext varchar(250)
) engine = myisam;

insert into lastword (mytext) values 
('this is my car'),
('how are you,doing'),
('how is your)health'),
('this is not(working');

select *,
substring_index(replace(replace(replace(mytext,',',' '),')',' '),'(',' '),' ',-1) as last 
from lastword

+----+---------------------+---------+
| id | mytext              | last    |
+----+---------------------+---------+
|  1 | this is my car      | car     |
|  2 | how are you,doing   | doing   |
|  3 | how is your)health  | health  |
|  4 | this is not(working | working |
+----+---------------------+---------+
4 rows in set (0.00 sec)

如您所见，您将不得不使用大量嵌套替换来完成您的任务。
