' Suppose you have established the SQL Server database Unittree and created tables in the library:
' Units (ID Unit ordinal integer unique, name unit name string, upid parent unit ordinal number integer)
' Note: Upid=0 indicates that the unit is a root node unit;
' Enter some data such as: (1,aa,0) (2,aabb,1) (3,aacc,1) (4,aabb11,2)
' For the following program test.
%>
<% ' Establish a database connection
Set Conn=server.createobject ("Adodb.connection")
Conn.Open "Provider=sqloledb;data source=yoursrcname;user id=sa;password=;d atabase=unittree"
%>
<% ' Sub process: Spanning Tree Touzi node data
Sub TreeNode (Code)
sqlunit= "Select Id,name" &_
