//删除

M('myop_myinvite')->where($map)->delete(); //成功返回删除记录个数，失败返回false

//保存

M('user')->where("uid={$this->mid}")->data($data)->save(); //data为数组，成功返回影响的行数，失败返回false

M('user')->setField('domain',$domain,'uid='.$this->mid); == M('user')->where($map)->setField('email', $_POST['email']) //成功返回影响的行数，失败返回false

//查询

$user = M('user')->where('uid='.$this->mid)->field('email,uname')->find(); //单记录

$count = M( 'UserTag' )->where( 'uid='.$this->mid )->count(); //查询条数

M('comment')->where('`id`='.$_POST['to_id'])->getField('uid'); //按字段查询

M('WeiboAttach')->where("weibo_type=1")->limit(10)->order("weibo_id DESC")->findAll(); //查询所有记录

$res= M('myop_myinvite')->where($map)->order('appid DESC')->findPage('10');  //每页10条记录

//原始执行sql语句

$res= M('')->query($sql);
