I have the following query that extends from Zend_DB_Table_Abstract

$select = $this->select()
            ->from('expense_details',
             array('SUM(expense_details_amount) AS total'))
        ->where('YEAR(expense_details_date) = ?', '2010')
            ->where('MONTH(expense_details_date) = ?', '01')
            ->where('expense_details_linkemail = ?', '[email protected]');

However it returning a NULL value despite its "equivalent" returning the desired value

SELECT SUM(expense_details_amount) AS total FROM expense_details
WHERE 
YEAR(expense_details_date) = '2010'                     
AND MONTH(expense_details_date) = '01'
AND expense_details_linkemail = '[email protected]'

Is my Zend_DB_Table construct above correct?
