Is that possible? I know how to do it with a program but is there any query to do it without the support of primary or foreign key?
那可能吗？我知道如何使用程序，但有没有任何查询，没有主键或外键的支持？

In MySQL I don't think it is possible. If the MySQL user running query has the DELETE privilege, then they will be able to delete any row.
在MySQL中我认为不可能。如果运行MySQL查询的用户具有DELETE权限，则他们将能够删除任何行。
