更新SQL記錄在Drupal

Question

我需要改變的評論的狀態來更新50K記錄（車削讀&讀取/寫入禁用），並希望確保我的SQL語句是正確的：

$query = "UPDATE node.nid AS nid, node.comment AS node_comment, node.type AS node_type 
     SET node.comment = '0' 
     WHERE (node.type in ('article', 'blog', 'event')) 
     AND (node.comment in ('1','2'))"; 

$total = 0; 
$count = 0; 
while ($query_result = db_query($query)){ 
    $count++; 
    $total++; 
    if($count>200){ 
     $count = 0; 
     sleep(300); 
    }  
} 
echo "Updated records:" . $total; 

我加在那裏定期暫停，所以它不會殺死服務器。這看起來好嗎？

我將UPDATE更改爲只是節點節點，並工作。
