这个错误很少见，排查了两个小时都不知道错在哪里，
这个是错误的sql.xml
<select id="findByClientId" resultMap="BaseResultMap">
SELECT <include refid="Base_Column_List" />
FROM client_info
where client_id= #{clientId}
/*where client_id= #{clientId}*/
</select>
乍一看 没问题 。后来尝试着把注掉的部分去掉就不报错了。
坑爹的xml
在mybites的xml配置文件里面，sql结尾不能加分号，否则报“ORA-00911”的错误
