如何避免商品删除级联操作中的冗余数据问题？

use demo;create table product(    id int,    name varchar(255),    primary key(id));create table product_link_1(    product_id int,    value varchar(255),    constraint product_link_1_fk foreign key(product_id)    references product(id));create table product_link_2(    product_id int,    value varchar(255),    constraint product_link_2_fk foreign key(product_id)    references product(id));create table product_link_3(    product_id int,    value varchar(255),    constraint product_link_3_fk foreign key(product_id)    references product(id));insert into product values(1, "Product 1");insert into product_link_1 values(1, "Product 1 Link 1");insert into product_link_2 values(1, "Product 1 Link 2");insert into product_link_3 values(1, "Product 1 Link 3");delete from product where id = 1;
