如何在没有createCommand的情况下从数据库中检索信息？

Question

I have following code in my controller:

$listproduct=Yii::app()->db->createCommand()
    ->select('product')
    ->from('product_form')
    ->where('product_name=:product_name and type=:type', array(':product_name'=>'HP', ':type'=>$gettype ))
    ->queryRow();

$gettype is responsible for retrieving types of the product. (e.g if the name of the product is HP and type($gettype) is PC, it will display the HP product where type is PC). I could not realize this function without createCommand. How can I do it?

Answer 1

You could use CActiveRecord features

assuming you have a CActiveRecode model class named

class ProductForm extends CActiveRecord
{
   /**
   * @return string the associated database table name
   */
   public function tableName()
   {
   .......

you could use

For obtain all the models you can use findAllByAttributes()

  $listProduct= ProductForm::model()->
      findAllByAttributes(array('product_name'=>'HP', 'type' =>$gettype ));

for obtain a single model you can use findByAttributes()
