我需要使用 Oracle SQL 获取经理的直接和间接报告，最高可达 3 级。
我正在使用 Oracle 的分层查询来获取报告。但我得到了一些奇怪的结果。
假设我有一个名叫 John 的经理。安妮向约翰报告，拉詹向安妮报告。
现在，如果我为 John 运行报告，那么如果 John 和向 Anne 和 Rajan 报告的报告，我应该得到所有的直接报告。拉詹有 5 名直接下属。
但是当我为 John 运行报告时，我只收到一份关于 Rajan 的报告。如果我为 Rajan 运行报告，则会获得 5 份报告。
这也发生在安妮身上。
并非所有的报告都列出了安妮在竞选约翰时的情况。
我没有得到这个问题。
这是我的代码：
