如何更新Composite外键

Question

这是我的父表

CREATE TABLE `parent` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `delete` bit(1) NOT NULL,
  PRIMARY KEY (`id`,`delete`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

这是我的孩子表

CREATE TABLE `child` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `parent_id` int(11) DEFAULT NULL,
  `parent_delete` bit(1) DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `parent_if_delete_idx` (`parent_id`,`parent_delete`),
  CONSTRAINT `parent_if_delete` FOREIGN KEY (`parent_id`, `parent_delete`) REFERENCES `parent` (`id`, `delete`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

我得到的输出：

+----+--------+
| id | delete |
+----+--------+
|  1 |      0 |
|  2 |      0 |
+----+--------+
CHILD
+-----+-----------+---------------+
| id  | parent_id | parent_delete |
+-----+-----------+---------------+
| 1   |         1 |             0 |
| 2   |         2 |             0 |
| 3   |         1 |             0 |
| 4   |         2 |             0 |
+-----+-----------+---------------+

如果我更新父ID和父删除标志，我的子行parent_id会更新，但我的删除标志不会更新。
