Answer 1

错误或多或少是不言自明的，只有当您阅读它们时。

我将大型执行拆分为单独的部分，逐个表。阅读我在每个评论开头写的评论。

不久：

如果一个对象已经存在，你就不能创建它；先放下（或重命名）
使用varchar2，而不是varchar
date 数据类型只是 "date"；它不接受格式或大小
创建主键约束时，Oracle 会自动创建索引；不要在该列上创建另一个索引
不要将数字括在单引号中
不要以字符串形式输入日期值；使用 DATE 文字或 TO_DATE 函数或 ALTER SESSION 到所需的日期格式
不要犯愚蠢的错别字；它是first_name，而不是fist_name
