CakePHP的$這個 - >型號 - >查詢返回

Question

當我運行這樣的查詢：

$this->User->query("DELETE FROM users WHERE deleted = 1 AND created <= '".$created."'"); 

我怎麼知道是否有正在運行的查詢時出現錯誤？

我想將消息發送給用戶，如果有一個錯誤是這樣的：

if(!$this->User->query("DELETE FROM users WHERE deleted = 1 AND created <= '".$created."'")) 
    $this->Session->setFlash('There was an error running this query'); 

此方法總是返回0，但

Answer 1

你想知道如果查詢無故障運行是否有錯誤，或者是否有記錄被刪除？

您可以使用類似$this->User->deleteAll代替

$this->User->deleteAll(array(
    'deleted' => 1 
    'created <=' => $created 
)); 

它會返回布爾TRUE成功，失敗假的。
