嗨，我無法得到yii中的最後10個元素，使用findby sql

Question

public function getGet($nid) 
     { 
      $sensor = $this->findBySql("select * from tbl_sensor where stype=4 and nid=$nid order by timestamp desc limit 10;"); 

     if ($sensor == NULL) 
     return "NULL"; 
     return $sensor->sdata; 
     } 

Answer 1

試試這個代碼。

echo "select * from tbl_sensor where stype=4 and nid=$nid order by timestamp desc limit 10"; 
$res= Yii::app()->db->createCommand("select * from tbl_sensor where stype=4 and nid=$nid order by timestamp desc limit 10")->queryAll(); 

//print_r($res); // will return array of result. 
// to check query, print the query executed. 

return $res;
