[fw-core] Zend_Db_Select Question

Hello, I have a question about Zend_Db_Select:

 

My question, does Zend_Db_Select have an option to where you can add an AND NOT clause like so.

SELECT COUNT(shift_id) as total FROM location_shifts WHERE location_id = '1' AND label = 'N1 SL' AND NOT shift_id = '5'

 

I currently have the select query setup like this.

$select = $this->select();

          $select->from($this->_name, array('total' => new Zend_Db_Expr('COUNT(shift_id)')))

                     ->where('label = ?', $label);

                    

            if ($locationID)

                  $select->where('location_id = ?', $locationID);

                 

            if ($shiftID)

                  $select->Where('shift_id = ?', $shiftID);

 

$select->limit(1);

 

And this is the generated output

SELECT COUNT(shift_id) AS `total` FROM `location_shifts` WHERE (label = 'N1 SL') AND (location_id = 1) AND (shift_id = 5) LIMIT 1

 

Thank you for your time in advanced
