如果您无法添加传播删除操作的约束,则必须自己编写所有必需的删除操作:
If you can't add constraints that propagates the delete, you have to write all the necessary deletes yourself:
delete employee where companyid in (select companyid from company c where productid = xxx);
delete company where productid=xxx;
delete product where productid=xxx;
