Traditional development SQL uses binary to identify uppercase and lowercase letters in query statements that can identify uppercase and lowercase letters: select uid from wjoy_log where binary uid='$uid' order by id desc cannot identify uppercase and lowercase letters: $res = WjoyLogModel::create( )->where('uid',$uid??'')->field('longurl')->order('id','desc')->get();What to do with the new one I can recognize it even if I write, please help
