我定义了一张关系表MemberSchool,里面存放的字段有college_id,senior_id,major_id
还有另外三张表college,senior,major表
这是我原先用查询语言的代码
还有另外三张表college,senior,major表

$memberSchool = M('Memberschool');
$where['member_id'] = array('EQ',$this->member_id);
$result = $memberSchool->field('college_name,major_name,school_name')
->join('JOIN __COLLEGE__ ON
__MEMBERSCHOOL__.college_id = __COLLEGE__.college_id')
->join('JOIN __SENIOR__ ON
__MEMBERSCHOOL__.senior_id = __SENIOR__.id')
->join('JOIN __MAJOR__ ON
__MEMBERSCHOOL__.major_id = __MAJOR__.major_id')
->where($where)
->find();
return $result;
现在我想利用关联模型的语句把他们的数据查询出来,请问要怎么查询呢?要以哪个表作为参照表呢?
