我尝试使用 CSQLDataProvider 获取值，但收到一条错误消息。未定义索引：id K:\yii-1.1.8.r3324\framework\web\CSqlDataProvider.php(116)

这是我的代码

楷模

class Product extends CActiveRecord{
...
public function getProductsForIndexPage(){
        $sql = '
            SELECT P.*  FROM Product P, Make M, Company C
            WHERE M.makeId=P.makeId AND C.companyId= P.companyId
        ';
        return new CSqlDataProvider($sql);
}
}

看法

$model = new Product(); 
$this->widget('zii.widgets.grid.CGridView', array(
        'dataProvider'=>$model->getProductsForIndexPage(),
        'columns'=>array(
                'name'

        ),
));

尝试这个：

 return new CSqlDataProvider($sql, array('keyField' => 'productId'));

Where 'productId'- 表中的 id 字段Product

Try this
