Yii - 直接执行SQL语句

例子如下：

例1

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

例2

$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"; }

例3

$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"; }

说明：把查询条件作为参数（如例2），比较安全，可直接避免注入。要是直接用在SQL语句中，最好要经过防注入处理。
