在MyBatis时，使用LIKE语句出错：WHERE payed > 0 CONCAT(orderNumber, phone, IFNULL(dorm, ''), IFNULL(room,'')) LIKE '%#{content}%'

从错误看，类似数组超界的错误，是在解析上面的sql出错的， '%#{content}%'，这里在解析出现的超界错误。

所以这个MyBatis的LIKE语句就不正确了，我从网上找到了LIKE的正确写法：http://happyqing.iteye.com/blog/2172397

也看到了#和$的区别：http://www.cnblogs.com/friends-wf/p/4227999.html
