MYSQL查询增强以获得正确的结果

Question

我有表“用户”：

+------+---------+  
| name | company |  
+------+---------+  
| John | a1a2a3  |  
| Mike | a10     |  
| Gorg | a3      |  
| Mary | a11     |  
+------+---------+ 

我正在尝试以下选择查询：

SELECT * FROM users WHERE company LIKE '%a1%'

结果如何：

+------+---------+  
| name | company |  
+------+---------+  
| John | a1a2a3  |  
| Mike | a10     |  
| Mary | a11     |  
+------+---------+ 

虽然我只需要：

+------+---------+  
| name | company |  
+------+---------+  
| John | a1a2a3  |  
+------+---------+

SELECT * FROM users WHERE company LIKE '%a1a%' or company LIKE '%a1'

从man page，这样的事情怎么样？

SELECT company REGEXP 'a1[^0-9]+';
