Question

拜托，有人可以帮我修改下面的mysql代码吗？

它不会影响我想要的行。：/我是初学者。

DELIMITER $$
DROP PROCEDURE IF EXISTS category$$


CREATE PROCEDURE category()
BEGIN
 DECLARE count INT DEFAULT 877;
 DECLARE prd INT;



 WHILE count < 1040 DO

   select product_id into prd from xxx_hikashop_product 
   where (replace(product_name, 'Model ', '') = count);

   insert into xxx_hikashop_product_category 
   (product_category_id, category_id, product_id, ordering)
   VALUES
   (1445+count, 33, prd, count);


   SET count = count + 1;
 END WHILE;
END$$

DELIMITER ;

PRINTED ERROR:

#1064 - You have an error in your SQL syntax; check the manual that

'select product_id from elody_hikashop_product where replace(product_alias, 
'mode' at line 7

Answer 1

我将假设product_alias字段的格式为＆＃34; Model 888＆＃34;并尝试提取数值，并将其与计数进行比较。您需要使用以下命令将结果字符串转换为数字：

select product_id into prd from xxx_hikashop_product
where (convert(replace(product_name, 'Model ', ''), UNSIGNED) = count);
