I just used this query to get desired output

$resource = Mage::getSingleton('core/resource');
$read = $resource->getConnection('core_read');
$select = $read->select()->from(array('cp'=>$categoryProductTable),array('sum(amount) as sum', 'name', 'address' ,'phone'));

The method addExpressionAttributeToSelect is only available as a method for the resource model. Since you've appended it after getSelect it wont be able to find the method.

$testmodel = Mage::getModel('donation/donation')->getCollection()
   ->addExpressionAttributeToSelect('SUM(`amount`)', 'amount')

Try above, that should work better

  • it didn't work I have to perform it using Zend Query Oct 14, 2015 at 10:37
