Question

我需要帮助创建一个层次结构组“使用”我的示例表中 Event_Role 列中的数据来创建如下所示的分组结构。

的6个父层次结构

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

子级别（或更低级别）是

Did Not Attend/Yes Attend for Attendee and Do Not Register/No Reg/Yes Reg for Registration.

我有100000多行来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

我在SQL Server中创建了示例数据

提前谢谢!!

Answer 1

看这个SqlFiddleLink可能会帮助你的朋友。我为您的层次结构组创建了另一个表 Group_EventRole 或（我的想法中的层次结构类型），我也将table1的Event_Role列更改为 int 。

名称是 Event_Role ， Name_Parent 是 Event_Role

的父级

从一个表列创建层次结构组包含父层和子层次结构信息
