Oracle SQL错误无效标识符

编辑：我解决了空值问题。现在我对无效的标识符感到困惑

我的任务是将ER图转换为SQL中创建的表

我有我的代码张贴在下面，但我得到了不少不同的错误。它们大多是重复出现的错误，但有2-3种不同的错误

有人能帮我解决这个问题吗

你在一小时前发布了同样的问题，得到了回答：@dnoeth-不是同一个问题，我被告知要做一个新问题。感谢mate的关注。错误消息非常清楚：

无法在“学生”、“驾驶员”、“驾驶员ID”中插入NULL

。您在

DRIVER

表中将列

DRIVER\u ID

声明为

NOT NULL

，然后您不能将NULL插入此列-这很明显。您还不清楚什么？在我的编辑中-我发现了，现在我对

无效标识符
感到困惑。“参与点”是什么？参与表中未定义。
