Convert mysql query to zend query?

Question

I want to convert following sql query to zend query. How I can convert this mysql query into zend query with zend framework 2?

SELECT SUM(amount)
FROM tbl_sale_amount 
WHERE sale_type_id=7459650 AND YEAR(db_add_date) = YEAR(CURDATE()); 

NOTE: Need to fetch sum of amount for current year from tbl_sale_amount.

Thanks

Answer 1

Use this

 $stmt = $db->query('SELECT SUM(amount)
    FROM tbl_sale_amount 
    WHERE sale_type_id= ? AND YEAR(db_add_date) = YEAR(CURDATE()',
                array($sale_type_id)
            );

$result = $stmt->fetchAll();
        $stmt->closeCursor();
        if ($result) {
            return $result;
        } else {
            return false;
        }
