This tutorial will help you to delete the record from database table using model in yii framework. I added the code to delete one or more record using yii framework model.
/** 1 **/
$model=User::model()->findByPk($id);
if($model)
$model->delete();
/** 2 **/
$model=User::model()->deleteAll();
/** 3 **/
$model=User::model()->deleteAll(array("condition"=>"userid='$id'"));
/** 4 **/
$mode=User::model()->deleteAll("status='A'");
