在channel表中查询status,channel_id,channel_name,account_level这些字段，且这些字段的channel_id不在adv_id为$id的表adv_channel_rule中：
$model = new Model(); $id = $req_models["id"];
tp5闭包子查询传参：
$res = $model->table(‘channel‘) ->field([‘status‘,‘channel_id‘,‘channel_name‘,‘account_level‘]) ->where(‘channel_id‘,‘NOT IN‘,function($query) use ($id) { $query->table(‘adv_channel_rule‘)->where("adv_id",$id)->field(‘channel_id‘); })->select();
mysql的原生写法：
$res = ‘SELECT adv_id,adv_name,status,account_level FROM `channel` WHERE channel_id NOT IN (SELECT channel_id FROM adv_channel_rule WHERE adv_id=‘.$id.‘)‘; $result = $model->query($res);
