Yii - 直接執行SQL語句(轉)

 
          $connection = Yii::app()->db;   
          
 
          $sql = "SELECT * FROM `project` ORDER BY id DESC";   
          
 
          $command =  
          $connection->createCommand( 
          $sql);   
          
 
          $result =  
          $command->queryAll();   
          
 
          print_r( 
          $result);   
         

 

$db = Yii::app()->db;  // you have to define db connection in config/main.php  
$sql = "select sum(if(starttime>'09:00:00',1,0)) as late,  
  sum(if(endtime<'18:00:00',1,0)) as early           
from present where userid=:userid and date between :date_start and :date_end"  
$results =  $db->createCommand( $sql)->query( array(  
  ':userid' => 115,':date_start'=>'2009-12-1',':date_end'=>'2009-12-31',  
));  
foreach( $results  as  $result){  
   echo  $result['late']," and ", $result['early']," /n";  

}   

 

說明：把查詢條件作為參數（如例2），比較安全，可直接避免注入。要是直接用在SQL語句中，最好要經過防注入處理。 

 

 

 $sql = "select sum(if(starttime>'09:00:00',1,0)) as late,  

             sum(if(endtime<'18:00:00',1,0)) as early            
          
 from present where userid=115 and date between '2009-12-1' and '2009-12-31'"   
          
 
          $results =  
          $db->createCommand( 
          $sql)->query();   
          
 
          foreach( 
          $results  
          as  
          $result){   
          
    
          echo  
          $result['late']," and ", 
          $result['early']," /n";   
          
 }
