/********************数据库操作的相关语法**************/

/********************查询**************/

$collect = $model->find(array('condition'=>'status > 0 ','order'=>'id desc','limit'=>5));

$collect->addtime;

Yii::app()->db->createCommand($sql)->queryAll();

Yii::app()->db->createCommand($sql)->queryRow();
Yii::app()->db->createCommand($sql)->execute();

/********************增加**************/

$model = new Industry();

$model->setAttribute('name', "");

$model->setAttribute('addtime', time());

if($model->save()){

$this->redirect('/seller/industry/index/');

Yii::app()->end();

}

/****************************统计*******************/

$num = $this->count(array("condition"=>"uid={$id} and token={$token}"));

//获取上次插入记录后的id

Yii::app()->db->getLastInsertID();

/********************修改**************/

//第一种方式

$user = new User;

$userinfo['updatetime'] = time();

$rs=$user->updateAll($userinfo, 'id=:user_id', array(':user_id'=>$user_id));

//第二种方式

public function actionUpdate($id){

$model = $this->loadModel($id);

$model->setAttribute('name', "");

$model->setAttribute('addtime', time());

if($model->save()){

$this->redirect('/seller/industry/index/');

Yii::app()->end();

}

}

public function loadModel($id)

{

$project=new Industry();

$model = $project->findByPk($id);

if($model===null)

throw new CHttpException(404,'The requested page does not exist.');

return $model;

}

//处理报错
print_r($model->getErrors());

//获取域名

Yii::app()->request->hostInfo

//获取参数 get或者post传值

Yii::app()->request->getParam('id');
