<property name=”hibernate.use_outer_join”>false</property>
 把这句设置成false 就不会产生 left outer join 的sql语句
 
如果ture通过关联 mapping 映射 many-to-one 产生的sql语句 不能执行 提示sql语法有错误
 
    <many-to-one name=”MemberInfo”
            insert=”false”
            update=”false”
            not-null=”true”>
            <column name=”member_no” />
            <column name=”corp_id” />
   </many-to-one>
