El siguiente SQL en VBA ADO da el error 'error de sintaxis en la cláusula From'.

Sub RunSQL2()

    Dim cn As ADODB.Connection
    Dim rs As ADODB.Recordset
    Dim strFile As String
    Dim strCon As String
    Dim strSQL As String
    Dim ws As Worksheet
    Dim strRangeAddress As String
    Dim dataRange As Range

    strFile = ThisWorkbook.Path & "\" & ThisWorkbook.Name
    strCon = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & strFile _
        & ";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1"";"

    Set cn = CreateObject("ADODB.Connection")
    Set rs = CreateObject("ADODB.Recordset")

    cn.Open strCon

    Set ws = ThisWorkbook.Sheets("mydata")
    strRangeAddress = ActiveSheet.Name & "$" & ws.Range("A1:C30020").Address(False, False)

        strSQL = strSQL & " (select s.* from "
strSQL = strSQL & " (select t.*, row_number() over (partition by child_level order by child_index,child_level) [rownum] from [" & strRangeAddress & "] t) s "
strSQL = strSQL & " where [rownum] = 1) u "
strSQL = strSQL & " join (select t2.*, 1 as  [rownum] from [" & strRangeAddress & "] t2) v "
strSQL = strSQL & " on (v.parent_level = u.child_level and v.[rownum] = u.[rownum]) "
strSQL = strSQL & " union select  w.child_index,w.child_level,w.child_level,w.child_index "
strSQL = strSQL & " from [" & strRangeAddress & "] w "
strSQL = strSQL & " where w.child_index = 1 "
strSQL = strSQL & " order by v.child_index;"


    rs.Open strSQL, cn

    Debug.Print rs.GetString

End Sub

El debug.print de strSQL es:

select v.child_index,v.child_level,v.parent_level,u.child_index as  parent_index 
from  
  (select s.* 
   from  
     (select t.*, row_number() over (partition by child_level order by child_index,child_level) [rownum] 
      from [mydata$A1:C30020] t
     ) s  
   where [rownum] = 1
  ) u  
join 
  (select t2.*, 1 as  [rownum] 
   from [mydata$A1:C30020] t2
  ) v  on (v.parent_level = u.child_level and v.[rownum] = u.[rownum])  

union 

select  w.child_index,w.child_level,w.child_level,w.child_index  
from [mydata$A1:C30020] w  
where w.child_index = 1  
order by v.child_index;

Cuando uso una cadena strSQL simple, la conexión funciona y devuelve resultados. Esto funciona:

strSQL = "SELECT * FROM [" & strRangeAddress & "]"

Creo que tengo la sintaxis correcta. ¿Es posible que el error surja de SQL no compatible? Por ejemplo, ¿puede ADO hacer 'Partición por'?

Estoy usando Excel 2010 de 64 bits de Office.
