How to set custom names for query columns ?

Answer 1

The simplest way:

$this->widget('zii.widgets.grid.CGridView', array(
    'dataProvider' => $model->search(), //$model = new SomeForm()    
    'columns' => array(
        'id::ID',
        'name::NAME'
    ),
));

Another way:

$this->widget('zii.widgets.grid.CGridView', array(
    'dataProvider' => $model->search(), //$model = new SomeForm()    
    'columns' => array(
        array(
            'header' => 'ID',
            'name' => 'id'
        ),
        array(
            'header' => 'NAME',
            'name' => 'name',
        ),
    ),
));
