我想知道是否有人能帮我。我在sql中运行了整个过程，但它给了我一个错误：
错误报告：SQL错误：ORA-0001:违反了唯一约束（GAMES.ATHLETE_PK）00001.00000-"违反了唯一约束（%s.%s）"*原因：UPDATE或INSERT语句试图插入重复的键。对于在DBMS MAC模式下配置的Trusted Oracle，您可以看到如果在不同级别存在重复条目，则显示此消息。*操作：删除唯一限制或不插入密钥。
我想在一个事务中同时插入所有记录。并且还使用序列来生成新的主键。我试着一个接一个地插入，没关系。但如果我一次插入所有内容，这就是错误。。。

发布的代码使用INSERT ALL语法在一条语句中插入多行。它尝试使用NEXTVAL序列为每一行生成一个唯一的标识符。
文件对NEXTVAL:的功能非常清楚
"在包含对NEXTVAL的引用的单个SQL语句中，Oracle将序列递增一次"
因此，对NEXTVAL的每个调用都将从序列中返回相同的值，因此语句抛出ORA-0001。
问题是OP的代码滥用了多表插入语法。它旨在将一组源数据中的行分布到多个表中，或者有条件地将这些行操作到一个表中。在任何一种情况下，它都假定源数据已经具有主键。
有多种方法可以解决这个问题，从对ID进行硬编码到使用多个单表插入语句。
这里有一种用发布的数据填充这些表的方法：
