你好我有一个工作查询，但我有点新的Zend我怎么能改变下面的查询到一个zend查询？

SELECT 
user_dob, 
user_dob + INTERVAL(YEAR(CURRENT_TIMESTAMP) - YEAR(user_dob)) + 0 YEAR AS currbirthday 
FROM user 
ORDER BY CASE WHEN currbirthday < CURRENT_TIMESTAMP 
THEN currbirthday + INTERVAL 1 YEAR 
ELSE currbirthday 
END 
LIMIT 4

这样的事情？没有测试，

$select = $sql->select ('user'); 

$select->columns(array(
      'user_dob', 
      'currbirthday' => new Expression('user_dob + INTERVAL(YEAR(CURRENT_TIMESTAMP) - YEAR(user_dob)) + 0 YEAR'))) 
->order (
    new Expression(' 
     CASE WHEN currbirthday < CURRENT_TIMESTAMP 
     THEN currbirthday + INTERVAL 1 YEAR 
     ELSE currbirthday 
     END' 
    ) 
);
