ThinkPhp多表查询的问题，求帮助
PHP code
public function graduate(){
$this->checkLogin();//判断登录
$Graduate=M('Graduate');
$category=$_GET['category'];
$map['FLG']='0';
$map['LAN']='01';
import("@.ORG.Page");
$count = $Graduate->join('LEFT OUTER JOIN PERSON ON(GRADUATE.PERSOnID=PERSON.PERSONID andPERSON.FLG='.$FLG.')')->where($map)->count();
$p = new Page ($count, 10 );
$list=$Graduate->limit($p->firstRow.','.$p->listRows)->join('LEFT OUTER JOIN PERSON ON GRADUATE.PERSOnID=PERSON.PERSONID and PERSON.FLG=0')->where($map)->order('GRADUATE.GRADUATEID DESC')->findAll();
$page = $p->show ();
$pagenumber=$p->nowPage;
$this->assign ("pagenumber", $pagenumber-1 );
$this->assign ("page", $page );
$this->assign ("list", $list );
$this->display();
}
Graduate表的personID是Person表的外键，join后查不到值，哪个大侠帮看看什么问题？
还有，这东西分大小写么？
ps：不会php，但是boss让买个bug。。。
------解决方案--------------------
$list=$Graduate->limit($p->firstRow.','.$p->listRows)->join('LEFT OUTER JOIN PERSON ON GRADUATE.PERSOnID=PERSON.PERSONID and PERSON.FLG=0')->where($map)->order('GRADUATE.GRADUATEID DESC')->findAll();
后面：
echo $Graduate->getLastSql();
看下最后sql执行语句是什么，是否sql有错误
