將PHP腳本轉換爲MySQL程序

-1

我在PHP中有一個腳本，我需要將其轉換爲MySQL程序。我無法運行PHP腳本，因爲這必須由MySQL觸發器執行。因爲我不知道如何在所有MySQL中解決這個問題，所以我使用PHP編寫了它。將PHP腳本轉換爲MySQL程序

下面的PHP腳本需要更改爲MySQL程序。該25和http://www.someurl.com/是變量，從扳機（new.order_id/new.store_url）填充：

$query = "SELECT 
      oc_order_product.quantity, 
      oc_order_option.option_value_id, 
      product.id 
      FROM oc_order_product 
      JOIN oc_order_option 
       ON oc_order_option.order_id = oc_order_product.order_id 
      JOIN product 
       ON product.oc_product_id = oc_order_product.model 
      WHERE oc_order_product.order_id = '25' AND oc_order_product.store_url = 'http://www.someurl.com/'"; 

$result = $mysqli->query($query); 
while($row = $result->fetch_object()){ 
    $query = "UPDATE product_option_value SET quantity = quantity - {$row->quantity} WHERE product_id='{$row->id}' AND option_value_id='{$row->option_value_id}'"; 
    $mysqli->query($query); 
}

@Dimitri我不知道這個問題會對我有何幫助？ – Timo002

奧凱，我發現我自己的答案閱讀互聯網連接做一些試錯後。

我創建了一個存儲過程，我將在更新觸發器上執行。

觸發

CREATE TRIGGER `order_gereed` AFTER UPDATE ON `oc_order` 
FOR EACH ROW IF new.order_status_id = "15" 
THEN 
CALL VooraadUpdate(new.order_id, new.store_url); 
UPDATE push_voorraad SET actie = '1'; 
END IF

過程

CREATE DEFINER=`root`@`localhost` PROCEDURE `VooraadUpdate`(IN `orderID` INT(11), IN `storeURL` VARCHAR(255)) 
    NO SQL 
BEGIN 
    DECLARE done INT DEFAULT FALSE; 
    DECLARE a, b, c INT; 
    DECLARE cur1 CURSOR FOR SELECT 
           oc_order_product.quantity, 
           oc_order_option.option_value_id, 
           product.id 
          FROM oc_order_product 
           JOIN oc_order_option 
           ON oc_order_option.order_id = oc_order_product.order_id 
           JOIN product 
           ON product.oc_product_id = oc_order_product.model 
          WHERE oc_order_product.order_id = orderID AND oc_order_product.store_url = storeURL; 
    DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE; 

    OPEN cur1; 
    read_loop: LOOP 
     FETCH cur1 INTO a, b, c; 
     IF done THEN 
      LEAVE read_loop; 
     END IF; 

     UPDATE product_option_value SET quantity = quantity - a WHERE product_id=c AND option_value_id=b; 

    END LOOP; 

    CLOSE cur1; 
END
