我正在尝试以这种方式更新第二张表
我有2张桌子
fr_hikashop_product： product_id，product_size_values（varchar（50））
fr_hikashop_product_category： id（自动递增）， product_id， category_id， category_parent_id
和触发器
CREATE TRIGGER trg_product_size AFTER UPDATE ON fr_hikashop_product
FOR EACH ROW
BEGIN
delete from fr_hikashop_product_category where category_id between 441 and 448 AND product_id = OLD.product_id;
insert ignore into fr_hikashop_product_category (product_id,category_id,category_parent_id) select NEW.product_id,441, 400 from fr_hikashop_product where product_size_values like '%41%' AND product_id = NEW.product_id;
insert ignore into fr_hikashop_product_category (product_id,category_id,category_parent_id) select NEW.product_id,442, 400 from fr_hikashop_product where product_size_values like '%42%' AND product_id = NEW.product_id;
etc ... up to 48
END //
让product_size_values = '41，43'
什么都没有发生，没有错误，但是我在表fr_hikashop_product_category中没有得到2个新行
感谢您的帮助
