如何在SQL命令，包括詞序

Question

這裏是我的查詢：

$select = $this->_conn->select(); 
    $select->from(array('usr' => $this->_prefix . 'user')); 
    $select->join(array('rol' => 'role'), 'usr.role_id = rol.role_id',array()); 
    $select->join(array('law' => 'lawyer_details'), 'usr.user_id = law.user_id', array('lawyer_url')); 
    $select->where("usr.user_status = ?","yes"); 
    $select->where("rol.role_key = ?","yes"); 
    $select->where("usr.user_section_show = ?","yes"); 
    $select->where("usr.managment_show = ?","yes"); 
    $select->limit(4); 
    $select->order(array('usr.user_firstname ASC')); 
    $rs = $select->query()->fetchAll(); 
    return new Obt_Model_RecordSet($rs, $this); 

我想user_firstname訂購，但首先要獲取用戶，其名稱是「XXX」，「YYY」，「LLL」 ;

Answer 1

試試這個： -

order by (user_firstname='xxx') DESC,user_firstname ASC 

Answer 2

在標準SQL中，你可以使用：

order by 
    (case when usr.user_firstname in ('xxx', 'yyy', 'III') then 1 else 0 end) DESC, 
    usr.user_firstname ASC 

Answer 3

- >序（新Zend_Db_Expr（「FIELD（usr.user_firstname， 'XXX'，」YYY 」， 'LLL'）「））;
