有没有人知道如何将Zend_Db的子句分组？基本上我有这个查询

$sql = $table->select()
             ->where('company_id = ?', $company_id)
             ->where('client_email = ?', $client_email)
             ->orWhere('client_email_alt = ?', $client_email);

哪个给了我这个:

SELECT `clients`.* FROM `clients` WHERE (company_id = '1') AND (client_email = 'email@address.com') OR (client_email_alt = 'email@address.com')

但我需要它给我这个,OR语句被分组:

SELECT `clients`.* FROM `clients` WHERE (company_id = '1') AND ((client_email = 'email@address.com') OR (client_email_alt = 'email@address.com'))
