yii fetching data using CSqlDataProvider

Question

I tried get values using CSQLDataProvider but I get an error Message. Undefined index: id K:\\yii-1.1.8.r3324\\framework\\web\\CSqlDataProvider.php(116)

Here is my code

models

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);
}
}

view

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

        ),
));

Answer 1

Try this:

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

Where 'productId' - id field in table Product

Answer 2

Try this

In model

public function reportSearch()
    {
        $query = "SELECT * FROM (";

        $countQuery = 'SELECT count(*) FROM (';
