```php
$db = Db::instance('development');
$db->update('mailList')->cols(array('status'=>1,'times'=>'times,$id);
$db->update('mailList',array('status'=>1,'times'=>new Zend_Db_Expr('times+'.1)),$where)
```
還是只能取的時(shí)候多取一個(gè)字段加$db->update('mailList')->cols(array('status'=>1,'times'=>$times+1))->where('id='.$id)->query();
```SQL
update mailList set status=1, times = times+1 where id =1;
```
