Pergunta
I have non-EAV model which extends Mage_Core_Model_Resource_Db_Collection_Abstract.
This is my code:
$this->getCollection()
->removeAllFieldsFromSelect()
->removeFieldFromSelect('credit_id')
->addFieldToSelect('product_id')
->addExpressionFieldToSelect('income', 'SUM({{income}})', 'income');
I need to group by *product_id* but all parents classes doesn't have this function. Is it possible to group by somehow?
Solução
This should work:
$this->getCollection()->getSelect()->group('product_id')
