Answer 1

你可以做如下：

$db = Zend_Db_Table::getDefaultAdapter(); 

    $select = $db->select(); 
    $select->from('advertisercontest', '*') 
      ->joinLeft(
        'advertiseraccount', 
        'advertiseraccount.loginid = advertisercontest.loginid', 
        array('advertiseraccount.advertiserid', 'advertiseraccount.companyname') 
        ) 
      ->where('advertisercontest.golive is not NULL');; 

    $result = $db->fetchAll($select); 

    var_dump($result); 

希望这是确定。
