Sql server 2008 从一个表列创建层次结构组时，该表列同时包含父层次结构信息和子层次结构信息

我需要帮助“使用”我的示例表中Event\u Role列中的数据创建层次结构组，以创建如下分组结构

这6个父层次结构是

'Speaker', 'Coordinator', 'Volunteer', 'Instructor', 'Attendee', 'Registration'

子层次结构（或更低级别）是

我有100000多行要创建这些层次结构组，我有更多的组和子层次结构

层次结构组

Speaker     
Coordinator     
Volunteer       
Instructor      
Attendee---   **child(Lv2)**-- Did Not Attend/Yes Attend
Registration--**child(Lv2)**---Do Not Register/No Reg/Yes Reg

我已经在SQLServer中创建了示例数据

提前谢谢你

看，这可能会帮助你的朋友。 我已经为您的层次结构组或（我认为是层次结构类型）创建了另一个表组事件角色，并且我还将您的表1的事件角色列更改为int

---

名称是你的事件角色，名称是你的事件角色

的父角色。为了呈现这样的数据，我建议你在SqlFiddle.com上创建一个示例，它将有助于你的事业。接下来，您可以显示您期望的输出是什么，因为您的解释还有很多需要改进的地方。
